_____________
1.1 Scope
Add the following new paragraph at the end of the subclause:
Annex E (normative) is added to provide details regarding the levels of compatibility to be
declared by the manufacturer as appropriate.
1.2 Normative references
Add the following new reference:
IEC 61076-3:2008, Connectors for electrical and electronic equipment – Product requirements
– Part 3: Rectangular connectors – Sectional specification
2 Terms and definitions
Replace definitions 2.1 and 2.2 with the following:
2.1
intermateability
intermateability (level 2 of IEC 61076-1:2006) 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 within
SEE: Clause E.3.
© IEC 2019
2.2
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.
Add, after Subclause 2.4, the following new terms and definitions:
2.5
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.
2.6
overall dimensions
dimensions providing the overall space occupied by a connector
Note 1 to entry: Two connectors of the same gender may have the same overall dimensions but different
mounting dimensions and/or different interface dimensions.
2.7
interface dimensions
set of dimensions required to fully describe the connector’s mating interface, belonging to
both the connector insert and to the relevant electric contacts
Note 1 to entry: Interface dimensions enable the proper functioning of a mated set of connectors according to the
relevant product detail specification or manufacturer’s detail specification.
Note 2 to entry: Two connectors with same interface dimensions have the same number of contact seats (or
positions), whereas they may not show the same number of contacts (ways).
2.8
mounting dimensions
dimensions enabling the mounting of a connector
Note 1 to entry: Examples of mounting dimensions are panel cutout size, size and interaxes of fixing holes or
threads.
Note 2 to entry: The geometry of the mounting interface of Printed Circuit Board connectors to the PCB belongs
to the mounting dimensions: two Printed Circuit Board connectors of the same gender with the same mounting
dimensions share the same pattern and pitch of their contacts.
Note 3 to entry: Two connectors not of the Printed Circuit Board type of the same gender with the same mounting
dimensions may have different interface dimensions.
Note 4 to entry: Two connectors of the same gender with the same mounting dimensions may have different
overall dimensions.
2.9
electrical wiring-related dimensions
dimensions related to the wiring of the connector, i.e. to its number and type of contacts
(ways)
– 4 – IEC 60603-7:2008/AMD2:2019
© IEC 2019
Note 1 to entry: Two connectors of the same gender with the same electrical wiring-related dimensions have the
same number of contacts (ways) or contact positions (seats), the same dimensions of these contacts or contact
positions, the same overall dimensions, the same interface dimensions, and if they are Printed Circuit Board
connectors, the same mounting dimensions
2.10
electrical, mechanical and climatic performances
levels of electrical, mechanical and climatic performance assigned to a connector in the
relevant product detail specification or manufacturer’s detail specification, therein verified
through dedicated groups of tests
Note 1 to entry: The electrical performance includes signal integrity.

Add the following new Annex E (normative):
Annex E
(normative)
Levels of compatibility
E.1 General
In applications where connectors according to IEC 60603-7 are used, a mixture of connectors
from different sources may be available. In cases where these products were given a different
rating by the manufacturer, and also when dimensional details are deviating, it is important to
know and consider the right level of compatibility.
The levels of compatibility are intended to compare connectors of the same gender on their
capability to be mated with a complementary connector of the different gender. The levels
indicate the functional differences (if any) between connector products of the same gender but
from different sources.
A product detail specification under this standard may declare a certain level of compatibility –
e.g. in terms of backward compatibility or of interoperability – with other product detail
specification(s) within the same family of standards (e.g. this IEC 60603-7 family or
IEC 61076-3 family) or with a cross reference to a connector covered by a product detail
specification belonging to a different IEC family.
In fact, for historical reasons some recent additions have been assigned to this IEC 60603-7
family of standards, while other new connectors have been assigned to the IEC 61076-3
family of rectangular connectors. For this reason a similar Annex has been included in the
generic specification IEC 61076-1 in order to align the terminology used in both families in
regard to levels of compatibility.
The levels of compatibility between connectors from different sources are characterized – as
a function of the standardization degree – by 4 levels. These levels are already defined in
2.2.3.2 to 2.2.3.5 of IEC 61076-1:2006 and shall, when appropriate, be indicated in the
relevant detail product specification of connectors.

The prefix “inter” in the terms “intermountable”, “intermateable”, “interoperable”, and “interchangeable” has the meaning of
“interchangeably” (adv), i.e. intermountable = interchangeably mountable, and so on. Thus the prefix “inter” has not the
meaning “among them”, i.e. intermountable does not mean “mountable among them”, intermateable does not mean “mateable
among them”. In other words, two intermateable connectors are not a male and
