Silver vs gold — same wire gauge
The 5-963715-6 uses silver contact finish; the same-series 5-963715-5 uses gold finish while sharing the same 18-20 AWG wire range, stamped construction, and crimp termination — the plating choice affects mating cycle life and corrosion resistance.
Wire gauge options in the series
The 5-968221-6 accepts 16-18 AWG wire with silver finish, while the 5-968221-1 accepts 18-20 AWG with tin finish — both are stamped socket contacts in the Micro Quadlok family.
