Active Production — No EOL Crosswind
The 76342-410LF: RoHS Compliant out of the tube.
20 Positions, Dual-Row, 0.100" Pitch — the BOM-Fit Baseline
The row spacing is also 0.100" (2.54 mm), so the PCB footprint is a 2×10 array on a 0.100" grid. All 20 positions are loaded — no skipped or dummy pins.
Through-Hole Termination and Stack Height
Termination is through-hole solder. The contact length — the post that goes through the board — is 0.114" (2.90 mm). This is the distance between the two PCBs when the receptacle is mated with its matching header — a critical dimension for mezzanine card spacing.
Where It Lands — Board-to-Board, Push-Pull
The contact type is a female socket with a square contact shape, designed to mate with a 0.025" square pin header from the same Dubox™ series.
Gold-Plated Sibling — 76342-310LF
The closest functional alternative is the 76342-310LF — identical in every dimension (20 positions, dual-row, 0.100" pitch, 11.04 mm stack height, through-hole, blue housing) except the mating contact finish. The 76342-310LF uses 30.0 µinch (0.76 µm) gold on the mating surface instead of tin. If your application demands higher mating-cycle life or a more corrosion-resistant interface, the gold-plated sibling is the better pick. The tin-plated 76342-410LF is the cost-optimised choice for lower-cycle, benign-environment boards.
