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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61076-2-104 has been prepared by subcommittee 48B: Electrical connectors, of IEC
technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment. It is an International Standard.
This third edition cancels and replaces the second edition published in 2014. This edition
constitutes a technical revision.

4.1 Recommended method of termination for connectors
The contact termination for rewirable connectors shall in accordance with the IEC 60352 series
or IEC 60999-1, as applicable, or shall be by soldering.
4.2 Connector coding, number of contacts, ratings and characteristics
Table 1 provides the coding of these connectors as a function of their style, number of contacts,
rated voltage and rated current.
Table 1 – Ratings of connectors

NOTE The rated current refers to the interface. It refers to the maximum conductor cross section that can be
terminated.
Insulation resistance: 10 Ω min.
Contact spacing:  see interface dimensions in 5.4
4.3 Systems of levels
4.3.1 Performance level
Connectors according to this document are classified by mating performance level (MPL).
See 6.5.1 for details.
4.3.2 Compatibility levels, according to IEC 61076-1
Connectors according to this document are intermateable and interoperable according to
IEC 61076-1 (level 3).
Interoperability is granted, provided that the same performance level as defined in 4.3.1 and
the same surface of contacts as defined in 6.2 is considered.
4.4 Classification into climatic categories
See 6.3.
4.5 Creepage and clearance distances
The creepage and clearance distances shall be dimensioned according to rated insulation
voltage values specified in Table 30 (see 6.4.1), in accordance with IEC 60664-1, and shall be
measured only in mated position according to IEC 60512-1-2 (see 4.8, connectors are without
breaking capacity (COC) unless otherwise specified by the manufacturer).
NOTE 1 Creepage distances can be dimensioned for pollution degree 2 for connectors IP54 or higher, see
IEC 61984:2008, 6.19.3.
The creepage and clearance distances that cover performance requirements in IEC 60664-1
may be reduced, based on IEC TR 63040.
NOTE 2 As indicated in IEC 60664-1, IEC TR 63040 provides an alternative and more precise dimensioning
procedure for clearances equal to or less than 2 mm.
In practice, reductions in creepage or clearance distances can occur due to the conductive
pattern of the printed board, or the wiring used, and should in such case duly be taken into
account.
NOTE 3 The permissible rated voltage depends on the application and the relevant specified safety requirements.
4.6 Current-carrying capacity
See 6.4.3.
4.7 Marking
The marking of the connector and the package shall be in accordance with IEC 61076-1.
4.8 Safety aspects
For safety aspects, IEC 61984 should be considered as guidance.
Connectors according to this document are COC per IEC 61984, unless otherwise specified by
the manufacturer.
