X
Denotes connector body plating material option. The only plating options allowable are Silver or
Nickel over brass in accordance with MIL-PRF-39012. Only connectors of the same materials shall
be mated to avoid dissimilar metal problems. CAUTION: A NICKEL PLATED BODY IS NOT FOR
USE IN APPLICATIONS WHERE PASSIVE INTERMODULATION GENERATION (PIM) MAY BE A
CONCERN (https://amphenolrf.com/simple/PIM%20Paper.pdf). Silver is the preferred plating
option.

1/ If a connector manufacturer produces a connector which meets all the requirements for two or more
connector PIN's (within the same series), the manufacturer may receive qualification approval for two
or more connector PIN's qualifying the one connector. It is not necessary that such connectors be in
the same group. Each connector, however, must be marked with its own appropriate PIN. For group
qualification, the connectors must be of similar design and be of the same materials and plating.
2/ For qualification retention, where more then one part is listed in a group in this column, data may be
supplied on any of those parts in order to retain qualification for those parts in the corresponding right
hand column. The part does not necessarily have to be the part initially qualified.
