The part is ROHS3 Compliant per TE's compliance documentation.
This unshrouded header mates with MTA-100 series IDC or crimp receptacles (such as the 3-640441-3 or 3-641215-3 families) that accept 22-26 AWG wire. Termination is through-hole solder — the kinked pin (0.110" post length) provides retention in the PCB hole during assembly.
The natural color insulation is standard for MTA-100 headers.
