Plating split and what it means
The 57102-F06-11ULF: The mating face carries a gold flash — adequate for a limited number of matings, not for high-cycle service. The solder-post side is tin-plated at 78.7 µin (2.00 µm), which gives strong solder-wetting and a durable permanent joint. Treat this as a signal-header plating grade rather than a power-cycle contact: the 2 A per circuit rating is real, but the gold flash is the limiting factor on reconnect duty, not the current ceiling.
Ratings summary
Voltage rating is 200V AC/DC — the insulation material is thermoplastic rated UL94 V-0, which sets the temperature ceiling for the housing. Contact material is copper alloy. Black insulation is standard for this series; colour is not a selection parameter but confirms the tube packaging lot.
