Board-to-Board Receptacle — Dubox™ 10-Position, 0.100" Pitch
The 71991-305 is a 10-position, dual-row board-to-board receptacle from the FCI Dubox™ series, designed for through-hole soldering to a PCB. The housing is blue thermoplastic, glass-filled, rated UL94 V-0 for flammability. The connector uses a push-pull fastening system — no locking latch, so it's best suited for applications where the mated pair won't see continuous vibration.
