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.
3/ Qualification by similarity may be given for the like styles of currently qualified TNC series connectors
with the approval of the qualifying and preparing activity. Similarity will include, cable accommodation,
materials and plating, assembly procedures and crimp tools/dies, as a minimum.
