connectors for data transmissions with frequencies up to 1 000 MHz

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.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance
with this document may involve the use of a patent concerning connectors given in 3.2.2 and 3.2.4.
The IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he is willing to give free licences with applicants throughout
the world. In this respect, the statement of the holder of this patent right is registered with the IEC

This second edition of IEC 61076-3-104 cancels and replaces the first edition, published in
2003, and constitutes a technical revision.
Changes from the first edition of this standard (2003) include editorial changes throughout the
standard and:
1) an increase of upper frequency from 600 MHz to 1 000 MHz;
2) changes to the characteristics clause (Clause 6) and test schedules clause (Clause 7) to
align the document with test schedules of IEC 60603-7 series documents.
The text of this standard is based on the following documents:
FDIS Report on voting
48B/1678/FDIS 48B/1702/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 61076 series, under the general title Connectors for electronic
equipment – Product requirements, 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.

The terminology used in and applicable to this specification is stated in 2.1 of IEC 61076-1.
Some applicable terms are also covered in IEC 60512-1. (For definitions of terms used, refer
to IEC 60050-581.)
2.1.2 Transmission performance categories
In this IEC standard, the term “category”, when used in reference to transmission
performance, refers to those categories defined by ISO/IEC 11801:2002.
2.1.3 Interchangeability level
2.1.3.1 General
These connectors interchangeabey insofar as the intermateability and interoperability
requirements herein are ensured for mated connectors when individual connector halves are
from different sources.
2.1.3.2 Intermateability
Intermateability is ensured by applying the “Go” and “No-Go” gauge requirements herein, and
adherence to dimensional requirements herein.
2.1.3.3 Interoperability
Interoperability of different IEC 61076-3-104 connectors is assured by compliance with all
transmission requirements when the connector is mated with the respective “test” connector
as described in Annex C.
61076-3-104  IEC:2006(E) – 9 –
2.2 Groups of related connectors
Groups of connectors within a subfamily having common features. Typical examples are same
type and range but different style. A group of related connectors is covered by a single detail
specification.
