NOTES:
1. If a conn ector manufac tu r er produces a connector which meets al l the r equir em ent s for two or more
connec tor PI N s ( within the same ser i es) , the manufacturer may receive qualification approval for two
or more connector PINs by qualifying the one c onnector. It i s not neces sar y t hat such connector s be
in the same gr oup. Each connector , however , must be marked with its own appropr i ate PI N . For
group quali ficati on, th e connector s must be of similar desi gn.
2. F or qualifi cati on retention, where mor e than one part is li sted in a gr oup in this colu mn, data m ay be
