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.

International Standard IEC 60679-3 has been prepared by IEC technical committee 49:

Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control,

selection and detection.

This third edition cancels and replaces the second edition issued in 2001. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
• CO 01, CO 07, CO 10, CO 17 and CO 18 were deleted;

• The current pin layout of CO 06 was deleted. And new pin layout of CO 06 was added as

CO 40;
• New layout of CO 15 was added as CO 41;
• Two new enclosures, CO 42 and CO 43 were added.

Therefore revised edition includes 15 types of enclosures as in Table 1 of Clause 5.

FDIS Report on voting
49/1009/FDIS 49/1021/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of the IEC 60679 series, published under the general title Quartz crystal

controlled oscillators of assessed quality, can be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until the

stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to

the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

QUARTZ CRYSTAL CONTROLLED OSCILLATORS
OF ASSESSED QUALITY –
Part 3: Standard outlines and lead connections
1 Scope

This part of IEC 60679 specifies the outline dimensions and lead connections for quartz crystal

controlled oscillators with lead enclosures.
2 Guidance for the standardization of outline drawings for frequency control
and selection devices

In order to achieve a uniform presentation of outline drawings for frequency control and

selection devices, the following shall be considered.

a) An outline drawing shall show all dimensional and geometrical characteristics of an

enclosure necessary to ensure mechanical interchangeability with all other enclosures of

the same outline. Enlarged and detailed view may be used, if necessary.
b) The outline drawing shall consist of three parts:

1) A drawing with dimensional symbols (capital letter) as shown in Figure 1 with applicable

footnotes, if necessary.

2) A tabular listing relating to the drawing symbol to the actual dimensions. Where possible,

this shall be shown on the same page as the drawing.
3) An "actual-size" sketch (scale 1:1).
c) The outline drawing shall be executed in the third-angle projection.

d) The function and identification of the lead connections (termination) shall be determined by

agreement between the supplier and user. They shall not be defined on the outline drawing.

e) Descriptive footnotes may be used at the bottom of/ or adjacent to, the drawing with proper

reference to the body of the drawing.
f) All dimensions shall be in millimeters.
g) 0utline dimensions A, B, C, D and E shall be listed with maximum values only.

h) If there are plural identical enclosures with different height (C), C shall be expressed with a

suffix number such as C , C , etc. The following letter and number after the basic type

1 2

number (four digits) indicate the enclosure height and lead length. The identity references

are given in the table in the sheet.

i) Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum

values. If applicable, nominal dimensions may be added.

j) The spacing of the leads (termination) – symbol H – shall be listed with minimum, nominal

and maximum dimensions.

k) Leads (terminations) for soldering application shall be specified with the minimum length

dimensions (symbol L) only.

Lead (termination) for plug-in application shall be specified with minimum and maximum length

dimensions.

l) If leads (terminations) are provided with an undercut, dimensions U and W shall be listed

with minimum dimensions only.
3 Dimensions of crystal oscillator enclosure

The dimensions in this standard apply to the completed quartz crystal controlled oscillators.

Only those dimensions which meet the requirements of the guidance for standardization of

outline drawings are given (see Clause 2).
4 Lead connections

Recommendations for the lead connections of quartz crystal controlled oscillators are given in

Annex A to this standard. Lead connections shall always be given in the detail specification.

(1) An indication shall be provided to locate the position of lead No. 1.

2 The complete identity for any oscillator outline is a six digit type number consisting of the basic type number

(four digits) followed by a letter indicating the enclosure height and a number indicating the lead length. The identity

references are given in the table, where a dot indicates the missing information which is given on another line.

EXAMPLE CO 22 A1 is therefore the complete identity of this enclosure.

(1) The presence of lead No.1 is optional.
(2) The position of the hole should be on the side of leads No.1 and No.4.

(four digits) followed by a letter indicating the enclosure height and a number indicating the lead length. The

identity references are given in the table, where a dot indicates the missing information which is given on another
