NOTES: 1. For qualification retention, where more than one part is listed in a group in the middle 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. This note does not apply if there is only one port listed in the middle column. 2. If a connector manufacturer produces a connector which meets all the requirements for two or more connector PINs (within the same series), the manufacturer may receive qualification approval for two or more connector PINs by 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. 10 MIL-PRF-39012/55H w/AMENDMENT 2 TABLE V. Category B - nonfield replaceable (special tools may be required).
