All 50 positions are loaded — no dummy or omitted contacts. The female socket accepts a square pin header, and the push-pull fastening means the pair stays mated by friction alone, no latch. ## 30 µinch Gold — Mating Cycle Life for Field Service Gold at this thickness is rated for 500+ mating cycles minimum — in a telecom or industrial panel where the board is removed quarterly, that is well over a century of reconnect duty at the interface. Confirm the derating curve from the product drawing before committing the BOM. The base product number is 71920, so any variant within that family shares the same footprint.","metaTitle":"71920-350LF Dubox 50-Position Receptacle 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 71920-350LF Dubox 50-position through-hole receptacle, 0.100\" pitch, 30 µinch gold mating contacts.
