Board-to-board receptacle, 11 positions, 0.100" pitch
The 68685-211LF: Mating contacts are gold-plated (15.0 µín), the solder tails are tin (100.0 µín), and the housing is rated UL94 V-0 PPS.
The 0.276" (7.00 mm) insulation height sets the board-to-board spacing when mated with a matching Dubox header — the receptacle sits above the board surface by that dimension, so the total stack height equals the header's mating post length plus 7.00 mm.
