The black housing accepts female socket contacts (sold separately) terminated by crimping, so you build the wire length and gauge to match your harness layout.
The latch lock snaps over the header shroud for positive retention. The Terminal Position Lock (TPA) Notched feature means the housing has a slot for a secondary lock that secures each terminal after insertion — a nice detail for production environments where a partially seated contact is a field failure waiting to happen.
If you need a current-production alternative, look at the active members of the Ultra-Fit 172256 series with the same 3.50mm pitch and single-row layout, but verify the position count and latch style match your application.
The 1722561104 housing accepts female socket contacts terminated by crimping. The contacts are not included with this part — you must order them separately. Use the Molex Ultra-Fit crimp terminals specified for the 172256 series; the exact order code for the contact depends on your wire gauge.
This part is obsolete and sourced to order.
