The 0022173122: ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive for global BOMs.
The white nylon (PA) housing with 0.311" (7.90 mm) insulation height provides clearance for board routing under the connector body.
ROHS3 compliant. Mating contact finish is gold at 15.0 µinch (0.38 µm) over brass; post finish is tin at 50.0 µinch (1.27 µm).
Yes — board hooks are integrated into the through-hole solder tails to anchor the connector during soldering and resist cable strain.
