Product details

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.

Frequently asked questions

What is the closest functional second-source for 71991-802LF?

The 71991-808LF is the same series, same pitch, same stack height, same through-hole footprint — just 16 positions instead of 4. Both are active and share the same board layout for the populated rows.
