It mates with standard MTA-100 crimp-socket housings for board-to-cable wiring.
The male pins are gold-plated on the mating end (30.0 µin thickness) and tin-plated on the solder tails (150.0 µin). The gold layer supports repeated mating cycles without oxidation; the tin tails solder cleanly into plated through-holes.
Yes, the 3-647116-4 is RoHS3 compliant per the manufacturer's declaration.
