Wire gauge window and plating
The 175285-3 is the gold-plated crimp pin in TE's Dynamic D-3 series, accepting 20-24 AWG wire.
Peer contacts in the same series
The 175285-3 pin differs from the 1-1326032-0 socket and the 1326031-9 blade — both are 16 AWG tin-plated contacts in the Dynamic D-3 family, so the 175285-3 suits finer-gauge wire and gold-plated mating interfaces. The 929989-8 socket accepts 17-20 AWG with tin plating, a different wire range and plating grade than the 175285-3.
