Board-to-Board Header for Standard 0.100" Footprints
The Amphenol FCI 87052-138HLF is a 38-position, dual-row unshrouded header from the BERGSTIK® II series, built on the industry-standard 0.100" (2.54mm) pitch. It uses through-hole solder termination with square male pins, push-pull fastening, and a black UL94 V-0 rated housing. This is a fully loaded header — all 38 positions are populated, so the BOM line matches the circuit count directly without unpopulated pins to track. With a 0.770" (19.56mm) mating pin length and a 0.120" (3.05mm) solder post, this header suits standard through-hole board thicknesses and typical mating receptacles in the BERGSTIK II family.
38 Positions vs 36 Positions — Same Pitch, One Row More
The 87052-138HLF carries 38 positions against the 36 positions of the 87052-136HLF at the same 0.100" (2.54mm) pitch and dual-row layout. The two extra positions add one more pin per row, extending the header length by 0.200" (5.08mm) along the board edge. If the BOM calls for 36 circuits, the 87052-136HLF is the direct fit; for 38 circuits, this is the one.
