The black housing includes a Terminal Position Lock (TPA) notch — a secondary retention feature that confirms each crimped terminal is fully seated before the connector is mated. ## Termination and Contact Note The TPA notch in the housing accepts a separate Terminal Position Assurance (TPA) retainer (sold separately) that locks each terminal in place — critical for harness builds that see vibration or field service where a backed-out contact would open the circuit. This receptacle mates with the Ultra-Fit male header (plug) of the same 172258 series with matching 6 circuits and 3.50mm pitch. The free-hanging (in-line) mounting style means it is wired into a harness and not board-mounted, so the strain relief comes from the crimp and TPA, not a board anchor.","metaTitle":"Molex Ultra-Fit 1722581106, 6-Position Receptacle, Obsolete","metaDescription":"Molex Ultra-Fit 1722581106 6-position dual-row receptacle, 3.50mm pitch, latch lock, TPA notched.
