Part 7: Detail specification for 8-way, unshielded,
free and fixed 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.
International Standard IEC 60603-7 has been prepared by subcommittee 48B: Electrical
connectors, of IEC technical committee 48: Electrical connectors and mechanical structures
for electrical and electronic equipment.
This fourth edition cancels and replaces the third edition, published in 2008, its
Amendment 1:2011 and its Amendment 2:2019. It constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
– Revised the definitions for intermateability and interoperability; added new definitions.
– Corrected dimension line for dimension AZ2 in Figure 5.
– Corrected dimension line for dimension F1 in Figure A.1.
– Revised the reference to ISO/IEC 11801 to ISO/IEC 11801-1.

– 6 – IEC 60603-7:2020 © IEC 2020
– Added lower limiting temperature and upper limiting temperature definitions.
– Revised Table 1 to Table 8 so the column order is Minimum-Nominal-Maximum
dimensions (ascending order).
– Corrected Table 7: Climatic category and Upper temperature values to 90 °C (to be
consistent with the graph in Figure 10 and Note 1 in Figure 10).
– Revised the wording in 8.2, contact resistance, for clarification.
– Revised Figure 11 and Figure 12 and the wording in the Key below for clarification.
– Removed the sentences under the figure in the Introduction.
– Added Annex E.
The text of this International Standard is based on the following documents:
FDIS Report on voting
48B/2832/FDIS 8B/2843/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document 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 document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

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 specifications regarding a component of a higher numbered document, all lower
numbered documents must be considered as well. Figure 1 shows the interrelation of the
documents.

CONNECTORS FOR ELECTRONIC EQUIPMENT –

Part 7: Detail specification for 8-way, unshielded,
free and fixed connectors
1 Scope
This part of IEC 60603-7 covers 8-way, unshielded, free and fixed connectors and is intended
to specify the common dimensions (interface 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.

3.1
intermateability
intermateability (level 2 of IEC 61076-1) is ensured by application of the "Go" and "No‑Go"
gauge requirements in the standards that may be referenced, and by adherence to the
dimensional requirements therein
SEE: Clause E.3.
3.2
interoperability
interoperability of different IEC 60603-7 connectors and of IEC 60603-7 connectors with
connectors of other families (e.g. IEC 61076-3 series) is ensured by compliance with the
specified interface dimensions, when they have the same number of contacts, the same
electrical wiring-related dimensions and when the lowest electrical, mechanical and climatic
performance (performance level) among the two connectors is suitable for the intended
application
SEE: Clause E.5.
3.3
category
relevant level of transmission performance as given in ISO/IEC 11801-1
3.4
Keystone connector
is defined by its mounting features
Note 1 to entry: The dimensional requirements for the connector and its corresponding mounting panel are
defined in Annex D.
3.5
number of contacts
number of contacts (or ways) that a connector owns, including the protective and/or functional
earth contact(s), if any
Note 1 to entry: A connector for removable contacts is characterized by its number of contact positions (seats): its
number of contacts (ways) may be lower than the number of contact positions (seats).
Note 2 to entry: The same number of contacts does not grant the same electrical interface: the geometry of said
contacts may be different while their number is the same.
3.6
overall dimensions
dimensions providing the overall space occupied by a connector
Note 1 to entry: Two connectors of the same gender may have the sa
