Its 0.156" (3.96mm) pitch is wider than the common 0.100" headers, giving more room per contact for routing and a higher current ceiling before the temperature rise hits the housing limit.
Both the mating and post finishes are tin, not gold. For a 3-position header, expect the per-contact current to be in the 5-7 A range with 18-20 AWG wire at 25°C ambient; derate above that per the wire manufacturer's curve.
Yes, the 640387-3 is ROHS3 compliant per the manufacturer's listing.
