The 641211-4: The post finish is 150.0µin tin-lead, compatible with standard wave-solder processes. Current rating is listed as varying by wire gauge — the per-contact current ceiling is set by the wire size in the mating crimp terminal, not by the header itself.
The header has 4 positions in a single row, all loaded. The square male pins are on 0.100" (2.54mm) pitch. Pin 1 is typically marked by a polarizing notch or chamfer on the housing — refer to the MTA-100 product drawing for the exact orientation.
Yes, it is ROHS3 compliant. The contact post finish is tin-lead, which is exempt under certain RoHS categories; verify your application's exemption status.
