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 60603-7-3 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 60603-7-3 published in 2004. This first edition
constitutes a technical revision.
The text of this standard is based on the following documents:

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

INTRODUCTION
Applications have emerged which require the use of the interface described in IEC 60603-7:
1996, with certain performance specifications at higher frequencies. The parameters for this
performance include insertion loss, near end crosstalk (NEXT), far end crosstalk (FEXT), and
return loss. Based on application requirements, the specifications for these parameters
always apply to a mated connection of a free (plug) and fixed (outlet) connector. Details for
testing of connectors and test plugs are given in Annex C.

CONNECTORS FOR ELECTRONIC EQUIPMENT –

Part 7-3: Detail specification for 8-way, shielded,
free and fixed connectors, for data transmissions
with frequencies up to 100 MHz

1 General
1.1 Scope
This part of IEC 60603 covers 8-way shielded free and fixed connectors and specifies
mechanical and environmental requirements and electrical transmission requirements for
frequencies up to 100 MHz. These connectors are typically used as category 5 connectors in
class D cabling systems specified in ISO/IEC 11801:2002.
These connectors are intermateable, interoperable, and backward compatible with other
IEC 60603-7 series connectors. While the definition of interoperable is being discussed within
the IEC, “interoperable” in this standard means the following: the fixed and the free connector
are capable of interconnecting with any IEC 60603-7 series connector, and when it is
interconnected, it fully meets all requirements of the lower frequency IEC 60603-7 series
standard.
NOTE Transmission performance categories: in this IEC standard, the term “category”, when used in reference to
transmission performance, refers to those categories defined in ISO/IEC 11801:2002.

2.1 Terms and definitions
For the purposes of this document, the terms and definitions of IEC 60050(581), IEC 61076-1,
IEC 60512-1, as well as the following, apply.
2.1.1
interchangeability level
Level at which these connectors are intermateable, interoperable and backward compatible
with IEC 60603-7 series connectors

– 12 – 60603-7-3 © IEC:2008
2.1.2
intermateability
Intermateability is ensured by application of the “GO” and “NO-GO” gauge requirements
herein, and adherence to the dimensional requirements within
2.1.3
backward compatibility
Plug or jack which is in compliance with this detail specification, mated with a jack or plug in
compliance with any lower frequency IEC 60603-7 series standard, fully complying with the
requirements of the lower frequency IEC 60603-7 series standard
2.1.4
interoperability
Interoperability of different IEC 60603-7-3 connectors is assured by compliance with all
transmission requirements for the different IEC 60603-7-3 connectors when the fixed
connector is mated with a full range of “test” free connectors, or “test plugs”, as described
herein
