Product details

Board-to-board receptacle, 6 positions, 2.54 mm pitch

The 71991-803LF is the 6-position member of Amphenol ICC (FCI)'s Dubox board-to-board receptacle line, dual-row, with all positions loaded. Gold-plated mating contacts (15.0 µin) mate with a 0.100" pitch header to achieve a mated stack height of 11.04 mm. The through-hole solder termination and push-pull fastening suit bottom- or top-entry board stacking.

Position count within the Dubox series

At 6 positions the 71991-803LF sits at the low end of the Dubox dual-row receptacle family — the 2.54 mm pitch and row spacing, gold mating contacts, and 11.04 mm stack height are shared across the series, so match the position count to the circuit count on the board.
