Plating choice across the series
The 102128-1 (gold, 30.0µin) and the 102128-2 (tin, 50.0µin) share the same 22-26 AWG wire range and crimp termination — the plating grade drives the mating cycle budget, with gold preferred for repeated mate/unmate duty. Siblings 103455-2 (27-32 AWG, gold) and 1-87309-4 (20-24 AWG, gold) extend the wire range within the same Mod V contact system.
