The TPA notch accepts a separate Terminal Position Assurance retainer (sold separately) that slides over the loaded terminals to confirm each one is fully seated; without it, a partially inserted contact can pass a pull test but still back out in service.","metaTitle":"Molex Ultra-Fit 1722561103 3-Position Receptacle, Obsolete","metaDescription":"Molex Ultra-Fit 1722561103 3-position single-row receptacle, 3.50mm pitch, latch lock, TPA notched, contacts not included.
