The Amphenol FCI 79821-138HLF is a 38-position, dual-row BERGSTIK II unshrouded header with square male pins on the standard 0.100" (2.54mm) pitch.
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.
The 79821-138HLF is listed as RoHS compliant in the product specifications.
