Part 7: Detail specification for 8-way, unshielded,

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60603-7 has been prepared by subcommittee 48B: Connectors, of
IEC technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
This third edition cancels and replaces the second edition published in 1996 and constitutes a
technical revision. This edition includes the following significant technical change with respect
to the previous edition:
– Drawings and test schedules were updated based on the work done developing
IEC 60603-7-4.
– A corrected figure (Figure 10) illustrating a connector de-rating curve has been
prepared and inserted in the text.
– Annex D contains the dimensions that define the panel mounting features on the
connector and panel that were referenced as the Type A, variant 03 connector in the
previous edition.

FDIS Report on voting
48B/1883A/FDIS 48B/1917/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 IEC 60603-7 series, under the general title: Connectors for electronic
equipment, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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.

INTRODUCTION
IEC 60603-7 is the base specification of the whole series. Subsequent specifications do not
duplicate information given in the base document, but list only additional requirements. For
complete specification regarding a component of a higher number document all lower
numbered documents must be considered as well. The following diagram shows the
interrelation of the documents:

It should be noted that during the preparation of the third edition of IEC 60603-7, the
subcommittee 48B Cat 6&7 project team members determined the current de-rating curve in
the standard was not correct. Several experts researched the current rating-temperature rise
measurements for 60603-7 style connectors and verified that the de-rating curve in the
published standard has been incorrect for many years. A corrected figure (Figure 10) has
been prepared and inserted in this edition.

1.1 Scope
This part of IEC 60603-7 covers 8-way unshielded free and fixed connectors, it is intended to
specify the common dimensions, mechanical, electrical and environmental characteristics and
tests for the family of IEC 60603-7-x connectors.
These connectors are intermateable (according to IEC 61076-1 level 2) and interoperable with
other IEC 60603-7 series connectors.

4 Cable terminations and internal connections – Fixed and free connectors
4.1 General
A connector may include multiple terminations between the cable termination and the
separable contact interface. These may include press-in connections of fixed connector
contacts into PCBs for example. All terminations shall meet the relevant termination
requirements.
Free connectors are intended to be terminated to cable to provide connector and cable
assemblies. The connector manufacturer shall provide basic information concerning the type
of conductor (stranded, solid) to which the connector may be applied, and the type of
connection used (solder, insulation displacement, etc.). Specific details concerning wire
gauge size, type and thickness of conductor insulation, size and shape of cordage or cable
sheath, etc. are not intended to be part of this detail specification. Minor variations in a free
connector’s interior details to accommodate differing wire gauge sizes, outer sheaths, etc. do
not require the generation of new free-connector specifications.
4.2 Termination types
4.2.1 Solder terminations
(under consideration)
4.2.2 Solderless terminations
4.2.2.1 Insulation displacement terminations
Insulation displacement terminations shall conform to IEC 60352-3 or IEC 60352-4.
4.2.2.2 Crimp terminations
Crimp terminations shall conform to IEC 60352-2.
4.2.2.3 Insulation piercing terminations
Insulation piercing terminations shall conform to IEC 60352-6.
4.2.2.4 Press-in terminations
The compliant pin shall conform to IEC 60352-5.
4.2.2.5 Spring clamp terminations
Spring clamp terminations shall conform to IEC 60352-7.
4.2.2.6 Other types
In the case where a type of solderless termination is used which is not covered by any IEC
standard and the supplier cannot demonstrate a similar level of performance or there is no
applicable IEC 60352 standard to be used as a reference, the supplier shall show
conformance with the full test schedule in 7.7 for all possible variations of termination, for
example each cable construction type (screen construction types, wire construction (solid,
flexible)) the connector is intended to be used for.

minimum.
= Surface roughness, according to ISO 1302.
Ra = 0,25 μm maximum.
A 0,01 mm wear tolerance shall be applied.
Clearance shall be provided for connector contacts.
