The contact material is brass, a standard conductor for this current range. Operating temperature range -40°C to 80°C covers indoor industrial cabinets and automotive passenger compartments, but not engine-bay or high-heat zones.
The mating pitch is 0.100" (2.54 mm), which is the standard 0.100-inch grid. The PCB footprint matches common KK254 headers.
Yes, it is ROHS3 compliant.
