Metric equivalents are given for information only. 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 (http://amphenolrf.com/simple/PIM%20Paper.pdf). Silver is the preferred plating option. Group qualification: See table II. TABLE II. Group qualification. 1/ 2/ Group I Submission and qualification of any of the following connectors M39012/21-X001 M39012/21-X002 M39012/21-X003 M39012/22-X001 Qualifies the following connectors M39012/21-X001 M39012/21-X002 M39012/21-X003 M39012/22-X001 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. 2 MIL-PRF-39012/22B w/AMENDMENT 1 TABLE III. Cross reference of PIN. PIN Substitute for type 1/ designation M39012/22-0001 UG-290/U 1/ The superseded PIN or the type designation is for cross reference only. The PIN M39012/ 22-XXXX shall be used in all cases for marking and identifying the connector. ENGINEERING DATA Nominal impedance: 50 ohms. Frequency range: 0 to 4 GHz.
