CONNECTORS FOR ELECTRONIC EQUIPMENT –

Part 3-104: Rectangular connectors –

Detail specification for 8-way, shielded free

and fixed connectors for data transmissions

with frequencies up to 600 MHz minimum

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
The International Electrotechnical commission (IEC) draws attention to the fact that it is claimed that compliance
with this document may involve the use of a patent concerning 8-way shielded free and fixed connectors for data
transmissions with frequencies up to 600 MHz minimum.
The IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he is willing to negotiate licences under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the
holder of this patent right is registered with IEC. Information may be obtained from
The Siemon Company
Siemon Business Park
76 Westbury Park Road
Watertown, CT 06795-0400
USA
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights
other than those identified above. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61076-3-104 has been prepared by subcommittee 48B:
Connectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
This standard cancels and replaces IEC/PAS 61076-3-104 published in 2002. This first edition
constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
48B/1303/FDIS 48B/1335/RVD

voting indicated in the above table.

2 Marking Information
2.1 IEC type designation
Connectors, connector bodies and connectors with pre-inserted contacts according to this
standard shall be designated by the following system.
Connectors conforming to this standard shall be identified by the following indications and in
the order given:
• the letters “IEC”;
• the number denoting this detail specification;
• the number of the detail specification (without dashes), being nine characters (e.g.
IEC 61076-3-104 B08 FS-G101-1 Shielded connector, fixed version B, having 8 female
contacts, solder termination, board mount));
• a letter denoting the style of the connector (the system shall be specified in the detail
specification.
2.2 Marking
Each connector and its associated package shall be marked in accordance with the
requirements specified in 2.6 of IEC 61076-1.
2.3 Groups of related connectors
Groups of connectors within a subfamily having common features. Typical examples are of

the same type and range but of a different style. A group of related connectors is covered by
a single detail specification.
– type: connectors within a particular subfamily such as a multicontact connector with one,
two or four pairs;
– range: the housing (shell) sizes and contacts arrangements within a type. For example a
housing containing one, two or four pairs;
– style: a particular connector within a type, for example fixed panel, PCB or free connector;
– variant: variations within a type, style or range.

61076-3-104  IEC:2003(E) – 9 –

2.4 Interchangeability level
These connectors shall be fully interchangeable and intermateable. The mechanical and

electrical characteristics shall be met whatever is the source of the connector. Moreover, it is

desirable that the mechanical and electrical compatibility with lower performance connecting

hardware as defined in ISO/IEC 11801 and IEC 60603-7 is ensured when connected to this

connector.
This can be achieved through the use of an adapter cord. Elements of connecting hardware,

for example plugs, sockets that terminate more than one cable are permitted.

The plug/socket interface may be constructed so as to permit the use of multiple modules, for
example 2 × 2 pairs or 4 × 1 pair plugs mated directly with a single 4 pairs socket.

4 Characteristics
4.1 General
Compliance to the test schedules is intended to ensure the reliability of all performance
parameters, including transmission parameters. Stable and compliant contact resistance is a
good indication of the stability of transmission performance.
4.2 Terminology
The terminology used in and applicable to this standard is stated in 2.1 of IEC 61076-1.
IEC 60512-1 also contains applicable terms.
4.3 Classification into climatic categories
The lower and upper temperatures and the duration of the damp heat, steady state test
should, unless otherwise impractical, be selected from the preferred values stated in 2.2 of
IEC 61076-1. The connectors are classified into climatic categories in accordance with the
general rules given in IEC 60068-1. The following preferred temperature range and severity of
the damp heat steady state test has been selected.

4.4 Creepage and clearance distances

The permissible operating voltages depend on the application and on the applicable or

specified safety requirements.

Insulation co-ordination is not required for this connector; therefore, the creepage and

clearance distances in IEC 60664-1 are reduced and covered by overall performance

requirements.
Therefore, the creepage and clearance distances are given as operating characteristics of

mated connectors.
In practice, reductions in creepage or clearance distances may occur due to the conductive
pattern of the printed board or the wiring used, and shall duly be taken into account.
