Board-to-Board Receptacle — 28 Positions at 0.100" Pitch
The 76342-314LF: The through-hole termination with a 0.114" (2.90 mm) post length suits conventional wave-solder assembly. Contact finish is 30.0 µinch (0.76 µm) gold on the mating side over phosphor bronze, with a tin post finish (78.7 µinch / 2.00 µm).
Mechanical Fit and Stacking Height
In a vibration-prone assembly, a secondary retention method (board locks or adhesive) should be evaluated. Insulation height is 0.275" (6.99 mm), and the mated stacking height is 11.04 mm — this defines the z-height budget between parallel boards.
