It uses a 0.100\" (2.54 mm) pitch on both rows and between rows, which is the standard footprint for legacy and current PCB layouts — no routing surprises. All 52 positions are loaded with square male pins in phosphor bronze, finished with 15.0 µ\" (0.38 µm) gold on the mating surface. That gold thickness supports repeated mating cycles in environments where tin would fret, so it suits field-serviceable or test-point interconnects where the header sees more than a few insertions. ## Key ratings and what they mean for the fit Rated 5 A per contact at 110 V, this header handles signal-level current and moderate power distribution across the 52 circuits. The 5 A figure is per-pin at the rated temperature rise — derate if the ambient inside the enclosure runs above 25 °C. The 0.100\" pitch gives enough creepage for the 110 V rating without crowding the board, so a 2-layer PCB with standard clearance rules will route cleanly. The through-hole solder termination (contact length - post 0.107\") provides a stronger mechanical anchor than an SMT equivalent, which matters when the mating cable or board applies lever forces during insertion or removal. ## Construction and compliance The housing is rated UL94 V-0, so the header is acceptable inside equipment that requires a flame-retardant enclosure. The black insulation stands 0.100\" above the board surface, which is low-profile enough to fit under a mezzanine board or a shroud. The push-pull fastening type means no latch — the retention comes from the friction of the pin-to-receptacle interface, so the mating half should include a positive lock if the assembly sees vibration. ## Sourcing and lifecycle The 67998-252HLF carries an Active lifecycle status from the manufacturer — no end-of-life notice, no last-time-buy window. No official cross-reference or direct replacement is listed, so the BOM line should reference this exact base product number 67998.","metaTitle":"FCI 67998-252HLF BERGSTIK II Header, 52-Pos, 0.100\" Pitch","metaDescription":"FCI BERGSTIK II unshrouded header, 52 positions, 0.100\" pitch, dual-row, through-hole, 5 A, 15.0 µ\" gold plating.
