Overview

IEC 61076-1:2006, titled "Connectors for electronic equipment - Product requirements - Part 1: Generic specification," is an international standard developed by the International Electrotechnical Commission (IEC) focusing on uniform specifications for electronic connectors. This standard applies broadly to families of connectors used in electronic and electrical equipment but explicitly excludes those intended for radio frequency use. It provides a generic framework for product requirements, ensuring compatibility, reliability, and performance in electronic connector design.

This standard is regularly updated to align with technological advances and industry best practices, with the latest consolidated edition including amendments up to 2019. The document aims to harmonize connector specifications to facilitate international cooperation, streamline manufacturing quality, and support interoperability in electronic equipment.

Key Topics

• Scope and Applicability
  IEC 61076-1 establishes uniform technical information and general requirements for connectors that do not operate at radio frequencies. It sets a foundation for connector families in electronic and electrical systems.

• Product Specification Structure
  The standard separates the documentation into two main parts:

  • Product requirements (covering general and detailed specifications, dimensions, performance characteristics, and test schedules).
  • Quality assessment requirements (addressing capability approval, technology approval, and qualification).

• Performance Characteristics
  Requirements cover key factors such as:

  • Operating environment conditions (temperature, humidity, and climatic categories).
  • Electrical properties including current-carrying capacity and insulation.
  • Mechanical properties like durability, mating cycles, and mechanical strength.
  • Compatibility and interchangeability criteria to ensure connectors from different manufacturers or batches are functional together.

• Testing and Quality Assessment
  The standard introduces modern quality control concepts such as:

  • Capability Approval (CA) for connector families demonstrating production consistency.
  • Technology Approval (TA) covering processes used in connector manufacturing.
  • Qualification Approval (QA) ensuring connectors meet specified environmental and mechanical performance levels.

• Marking and Identification
  IEC 61076-1 specifies requirements for clear connector markings, including product codes and package labeling to enhance traceability and correct application.

• Dimensional and Engineering Drawings
  Provides guidelines on technical drawings, dimensional data, and gauge usage to guarantee dimensional conformity among connector components.

Applications

IEC 61076-1 is essential for manufacturers, designers, and quality engineers working with electronic connectors in a broad range of industries:

• Electronic Equipment Manufacturing: Ensures connectors used in computers, industrial electronics, consumer electronics, and automation devices meet standardized criteria.
• Electrical Systems Design: Facilitates implementation of robust connectors in power supplies, control panels, and electrical devices.
• Quality Assurance Processes: Supports systematic inspection and certification to maintain manufacturing consistency and product reliability over time.
• Supply Chain and Interoperability: Assists in selecting and verifying connector components compatible across suppliers and applications, improving operational efficiency.
• Product Development: Guides early-stage connector design and development with clear performance and testing benchmarks.

Related Standards

IEC 61076-1 works in conjunction with other IEC and ISO standards related to connector design and testing, including:

• IEC 62197-1 – Connectors for electronic equipment; often used together for detailed connector specifications.
• IEC 60512 Series – Connectors for electronic equipment – Tests and measurements.
• IEC 60068 Series – Environmental testing standards relevant to climatic categories defined in IEC 61076-1.
• ISO/IEC Directives Part 2 – Framework for the preparation of international standards, influencing the structure of IEC 61076-1.
• Additional IEC TC 48 Subcommittee 48B Specifications – Detail specifications for families of connectors expanding on the generic requirements.

---

By adhering to IEC 61076-1:2006 standards, stakeholders can enhance interoperability, ensure high-quality, and maintain reliable connector performance across global electronic equipment markets. The standard’s emphasis on product requirements and modern quality assessment processes provides a consistent foundation for manufacturing and applying electronic connectors worldwide.

INTRODUCTION
Ces travaux sont destinés à mettre à jour les procédures d'assurance de la qualité des
spécifications pour connecteurs afin de prendre en compte les processus industriels
correspondant à l'état de l'art actuel.
A l'heure actuelle, toutes les spécifications particulières pour connecteurs du ressort du sous-
comité 48B de la CEI sont construites comme indiqué à la Figure 1 avec 5 chapitres
principaux.
Les procédures dépassées les plus importantes sont celles qui concernent les essais lot par
lot avec différents niveaux de contrôle et un niveau d'acceptation de la qualité et les essais
périodiques avec un nombre autorisé de défauts.
Il a été considéré comme nécessaire d'introduire l'agrément de savoir-faire et l'agrément de
technologie avec les paramètres de conception de base de la maîtrise statistique des
processus comme système de retour d'informations pour avoir un contrôle continu de la
qualité au cours des différentes étapes de la fabrication.
Il est également apparu approprié de diviser l'actuelle structure des documents en deux
structures séparées de documents qui, dans l'utilisation au quotidien des spécifications,
satisfont la plupart des utilisateurs, voir la Figure 2.
Le système de documents sera divisé en deux parties:
• Des exigences de produit
• Des exigences d'assurance de la qualité
La structure concernant la spécification de produit contient les exigences de caractéristiques,
de dimensions, de performances et les programmes d'essais.
La structure concernant les spécifications d'assurance de la qualité contient les exigences
pour obtenir l'homologation (QA) pour un niveau de performance donné (par catégorie
d'environnement), l'agrément de savoir-faire (CA) par famille de connecteurs ou l'agrément de
technologie (TA) qui comprend toutes les technologies entrant dans la production des
connecteurs.
L'agrément de savoir-faire ou l'agrément de technologie combiné aux paramètres de maîtrise
statistique des processus sont destinés à remplacer les essais lot par lot et périodiques.
Pour homologuer complètement un produit, l'utilisateur doit choisir une combinaison des deux
structures en gardant à l'esprit que, dans la maîtrise statistique des processus, les
caractéristiques clés doivent faire l'objet d'un accord entre le fabricant et l'utilisateur.
Une spécification générique de produit avec la structure à 4 niveaux comprend une
spécification générique, une spécification intermédiaire, une spécification particulière cadre et
une spécification particulière.
On peut en conclure que deux spécifications génériques sont diffusées, une pour les aspects
de produit et l'autre pour les aspects de qualité.
Les spécifications intermédiaires seront présentées au niveau du produit par famille de
connecteurs par exemple connecteurs pour cartes imprimées, connecteurs circulaires,
connecteurs rectangulaires, etc.

INTRODUCTION
The objective of this work is to update the quality assessment procedures of the connector
specifications to the current state of the art industrial procedures.
At the time of publication, all the connector detail specifications dealt with by subcommittee
48B of the International Electrotechnical Commission were built as described in Figure 1 with
5 major chapters.
The most significant out of date procedures relate to the lot-by-lot tests with different
inspection levels and acceptance quality level and to the periodic tests with permitted number
of defectives.
It was felt necessary to introduce the capability and the technology approval together with the
basic design parameters of statistical process control as a feed back system to have a
continuous control of the quality during the various steps of manufacture.
It was also felt appropriate to split the current documentation structure into two separate
structures of documents which, in the day to day use of specifications, satisfy most users, see
Figure 2.
The documentation system will be split into two parts:
• Product requirements
• Quality assessment requirements
The structure for the Product Specification contains characteristics, dimensions, performance
requirements and test schedules.
The structure for the quality assessment specification contains the requirements to obtain
Qualification Approval (QA) for a given performance level (per environment category),
Capability Approval (CA) per family of connectors or Technology Approval (TA) comprising all
relevant technologies for connector production.
Capability Approval or Technology Approval combined with statistical process control
parameters are intended to replace lot-by-lot and periodic tests.
To fully certify a product, a combination of the two structures will have to be selected by the
user, keeping in mind that in the statistical process control, key characteristics shall be
agreed between manufacturer and user.
A generic product specification with a 4 level structure consists of a generic, a sectional, a
blank detail and a detail specification.
From this, it can be concluded that two generic specifications are being circulated, one
document for the product aspects and a second one for the quality aspects.
The sectional specifications will be presented at the product level per family of connectors, for
example printed board connectors, circular connectors, rectangular connectors, etc.

L'objectif de cette 2 Edition est de réviser et de mettre à jour les spécifications de
connecteurs définissant les produits et les exigences d'assurance de qualité.
Actuellement toutes les spécifications particulières de connecteurs prises en compte par le
Sous Comité 48B de la Commission Electrotechnique Internationale sont préparées tel que
décrit dans la figure 1 avec 5 chapitres principaux.
Les procédures obsolètes les plus significatives concernent les essais lot par lot ayant
différents niveaux d'exigences et niveaux d'assurance de la qualité ainsi que les essais
périodiques avec les niveaux de défauts tolérés.
Pour mettre à jour ce document afin de prendre en compte des règles plus récentes, il a été
nécessaire d'introduire les procédures d'agrément de savoir faire et de technologie incluant
les paramètres de base de conception de la maîtrise statistique des procédés afin d'avoir un
contrôle continu de la qualité pendant les différentes étapes de fabrication.
Il a également été estimé approprié de séparer la documentation en deux parties qui au cours
de l'utilisation au jour le jour des spécifications, conviennent au plus grand nombre
d'utilisateurs, comme indiqué dans la figure 2.
Ceci permet à l'utilisateur d'acquérir des produits certifiés ou non. Il est évident qu'il est
nécessaire à l'industrie d'avoir des informations séparées sur les dimensions, les exigences
de performance et les paramètres de conception de base.
Les deux documents séparés concernent:
– Les exigences de produit
– Les exigences d'assurance de la qualité
La spécification de produit contient les caractéristiques, les dimensions, les exigences de
performance, et les programmes d'essais. Le document correspondant est:
CEI 61076-1 Ed. 2
Connecteurs pour équipements électroniques – Exigences de produit
Partie 1: Spécification générique.
La spécification d'assurance de qualité contient les exigences nécessaires à l'obtention de
l'agrément d'homologation (QA) pour un niveau de qualité donné (par catégorie
d'environnement), l'Agrément de Savoir Faire (CA) par famille de connecteurs ou l' Agrément
de Technologie (TA) comprenant toutes les technologies de référence pour la production de
connecteurs.
L'agrément de savoir faire ou l'agrément de technologie combinés avec les paramètres de
maîtrise statistique de procédé sont destinés à remplacer les essais lot par lot et les essais
périodiques. Le document correspondant est:

The objective of this 2 Edition is to review and update the actual connector specifications
containing product and quality assessment requirements.
Today, all the connector detail specifications dealt with by Subcommittee 48B of the
International Electrotechnical Commission are prepared as described in figure 1 with 5 major
chapters.
The most significant out of date procedures relate to the lot-by-lot tests with different
inspection levels and acceptance quality level and to the periodic tests with permitted number
of defectives.
To update the document to reflect modern practices it was necessary to introduce the
capability and the technology approval together with the basic design parameters of statistical
process control as a feed back system to have a continuous quality control during various
steps of manufacture.
It was also felt appropriate to split the current documentation into two separate structures of
documents which, in the day-to-day use of specifications, satisfy most users, see illustration
in Figure 2.
This offers the user the option to acquire products with and without certification. It is obvious
that the industry needs to get separate information on dimensions, performance requirements
and basic design parameters.
The two separate documents are:
▪ Product requirements
▪ Quality assessment requirements
The Product Specification contains characteristics, dimensions, performance requirements
and test schedules. The relevant document is:
IEC 61076-1 (Ed. 2)
Connectors for electronic equipment – Product requirements –
Part 1: Generic Specification.
The Quality Assessment Specification contains the requirements to obtain Qualification
Approval (QA) for a given performance level (per environment category), Capability Approval
(CA) per family of connectors or Technology Approval (TA) comprising all relevant
technologies for connector production.
Capability Approval or Technology Approval combined with statistical process control
parameters are intending to replace lot-by-lot and periodic tests. The relevant document is:
IEC 62197-1

To specify a fully certified product, a combination of specifications from both structures shall
be required.
The 4 level document structure adopted by SC48B consists of a Generic, a Sectional, a Blank
Detail and Detail Specifications.

Pour maintenir cette structure à 4 niveaux, deux Spécifications Génériques ont été diffusées,
la première concernant les aspects produit, et la seconde pour les aspects qualité.
Les Spécifications Intermédiaires seront présentées au niveau produit par famille de
connecteurs par exemple les connecteurs pour cartes imprimées, les connecteurs circulaires,
les connecteurs rectangulaires, etc. Pour les Niveaux d'Assurance Qualité l'Annexe B de la

To maintain this 4 level structure, two Generic Specifications are being circulated, one
document for the product aspects and a second one for the quality aspects.
The Sectional Specifications will be presented at the product level per family of connectors

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 61076-1 edition 2.1 contains the second edition (2006-04) [documents 48B/1621/FDIS and
48B/1671/RVD] and its amendment 1 (2019-01) [documents 48B/2678/FDIS and 48B/2691/RVD].

INTRODUCTION
The objective of this work is to update the quality assessment procedures of the connector
specifications to the current state of the art industrial procedures.
At the time of publication, all the connector detail specifications dealt with by subcommittee
48B of the International Electrotechnical Commission were built as described in Figure 1 with
5 major chapters.
The most significant out of date procedures relate to the lot-by-lot tests with different
inspection levels and acceptance quality level and to the periodic tests with permitted number
of defectives.
It was felt necessary to introduce the capability and the technology approval together with the
basic design parameters of statistical process control as a feed back system to have a
continuous control of the quality during the various steps of manufacture.
It was also felt appropriate to split the current documentation structure into two separate
structures of documents which, in the day to day use of specifications, satisfy most users, see
Figure 2.
The documentation system will be split into two parts:
• Product requirements
• Quality assessment requirements
The structure for the Product Specification contains characteristics, dimensions, performance
requirements and test schedules.
The structure for the quality assessment specification contains the requirements to obtain
Qualification Approval (QA) for a given performance level (per environment category),
Capability Approval (CA) per family of connectors or Technology Approval (TA) comprising all
relevant technologies for connector production.
Capability Approval or Technology Approval combined with statistical process control
parameters are intended to replace lot-by-lot and periodic tests.
To fully certify a product, a combination of the two structures will have to be selected by the
user, keeping in mind that in the statistical process control, key characteristics shall be
agreed between manufacturer and user.
A generic product specification with a 4 level structure consists of a generic, a sectional, a
blank detail and a detail specification.
From this, it can be concluded that two generic specifications are being circulated, one
document for the product aspects and a second one for the quality aspects.
The sectional specifications will be presented at the product level per family of connectors, for
example printed board connectors, circular connectors, rectangular connectors, etc.

 IEC 2019
At the quality assessment level, Annex B of IEC 62197-1 deals with qualification approval in
B.2, capability approval in B.3 and technology approval in B.4.

2.2 System of levels
2.2.1 General
The term level is used in the following different meanings and should clearly be distinguished.
All details of the levels and their combinations shall be specified in the detail specification.
A detail product specification may contain more than one performance level and compatibility
level.
2.2.2 Performance levels
The term performance level reflects the grouping of the environmental and mechanical
stresses at which a component is tested, and also such features as long-term stability of
electrical characteristics. These levels are numbered, where the lowest number (1) usually
indicates the highest performance.
2.2.3 Compatibility levels
2.2.3.1 General
As a function of the standardisation degree, 4 levels characterize the compatibility of
connectors from different sources. These levels are defined in 2.2.3.2 to 2.2.3.5 and shall,
when appropriate, be indicated in the detail product specification of connectors.
NOTE If connectors of different compatibility levels are mated, the lower level prevails.
2.2.3.2 Level 1 – Intermountable
This level standardizes only overall dimensions and mounting dimensions on printed board or
panel cut-out and cable termination assembly. Connectors from different sources are not
necessarily intermateable.
Information required in a detail specification in order to satisfy to this level is:
For printed board connectors:
– printed board layout;
– board distances and orientation (parallel or perpendicular);
– panel cut-out and location, if applicable.
For free cable connector, cable termination assembly characteristics shall be specified.
2.2.3.3 Level 2 – Intermateable
This level standardizes only dimensions of electrical and mechanical interfaces.
Electrical, mechanical and climatic performances of connectors from different sources, when
mated, are not fully guaranteed.
2.2.3.4 Level 3 – Intermateable and intermountable
This level standardizes mounting dimensions, electrical and mechanical interface and overall
dimensions.
Electrical, mechanical and climatic performances of connectors, from different sources, when
mated, are not fully guaranteed.

2.2.3.5 Level 4 – Interchangeable
This level standardizes all the elements guaranteeing compliance of the electrical, mechanical
and climatic performances of mated connector when individual connectors halves are from
different sources.
NOTE The complexity of demonstrating interchangeability at level 4 may be substantial and therefore should be
evaluated prior to the level being specified.
2.3 Classification into climatic categories
Connectors are classified into climatic categories in accordance with the general rules given
in IEC 60068-1.
Preferred temperature ranges and severities of the damp heat, steady state tests have been
selected, see Table 1. Any combination of these elements may be used, and should be written
in the format: for example 10/070/04, in the applicable sectional and detail product
specifications.
