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.

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.
