The 0.100\" (2.54 mm) pitch drives the board footprint — standard 0.025\" square pins on a 0.1\" grid, compatible with most prototyping perfboards and production layouts. The 40 positions in two rows mean a 20-pin-per-row footprint, 2.54 mm apart, with 2.54 mm row spacing. The 110 V rating is the working voltage — the unshrouded pins reduce creepage distance compared to a box header, so keep adjacent traces clear. ## Pinout and Mating Considerations The 67998-440HLF is a through-hole male pin header with all 40 positions loaded. The pinout follows standard dual-row numbering: pin 1 at one end of row A, pin 2 opposite in row B, alternating down the length. The 0.318\" (8.08 mm) mating pin length and 0.107\" (2.71 mm) solder post length are fixed — the overall contact length of 0.525\" (13.34 mm) determines the board-to-board stack height when mated with a matching receptacle. Use a female socket header with 0.100\" (2.54 mm) pitch and 0.025\" square pin acceptance for a reliable mate.","metaTitle":"Amphenol FCI BERGSTIK II 67998-440HLF, 40-Pin 2.54mm Header","metaDescription":"67998-440HLF BERGSTIK II header: 40 positions, dual-row, 2.54mm pitch, unshrouded, tin-plated, 5A/110V.
