Crimp pin for 20-26 AWG signal circuits
The 170429-3 is a gold-plated crimp pin from the TE Connectivity EI series, accepting 20-26 AWG wire.
Gold vs tin plating across the series
The 170429-3 uses gold contact finish; series peers 1-1326032-0, 1326031-9, and 929989-8 use tin finish at 16 AWG or 17-20 AWG — the plating grade difference drives mating cycle life, not current capacity.
