Board-to-Board Stacking with a Fixed 11.04 mm Gap
The 71991-802LF is a 4-position, 2-row female socket receptacle from the Dubox™ series, designed for board-to-board stacking at a fixed mated height of 11.04 mm.
Gold Mating Finish and What It Buys the Design
That thickness is rated for moderate cycle life — think a few hundred mates over the product lifetime, not a field-service connector cycled weekly. For higher cycle duty, the sibling 71991-302LF and 71991-305LF carry 30.0 µinch gold, doubling the wear layer.
The 4-position 71991-802LF is the smallest circuit count in the 71991 series.
RoHS compliant and rated UL94 V-0 for the glass-filled thermoplastic housing.
