Key Specs and Fit
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing define the board footprint — a standard grid that matches legacy 0.100" header patterns. The 0.430" (10.92mm) mating pin length engages with the receptacle before the housing bottoms out, and the 0.200" (5.08mm) post length is sized for a standard 0.062" (1.6mm) PCB.
