The Amphenol FCI (Amphenol FCI) 87900-124HLF is a dual-row, 24-circuit unshrouded pin header in the BERGSTIK II series — a standard board-to-board interconnect at 0.100 inch (2.54 mm) pitch built for through-hole soldering. Contacts are gold-plated to 30 µin (0.76 µm) over phosphor bronze, rated 5 A per circuit at the contact level, with square pin geometry and push-pull mating. All 24 positions are loaded. The 0.720 inch (18.29 mm) mating length and 0.940 inch (23.88 mm) overall contact length define the engagement window for the mating receptacle. UL94 V-0 rated housing, 110 V rating, black insulation. Ships in a bag.
Where this fits in BERGSTIK II
The 87900 base covers the BERGSTIK II dual-row footprint with position counts loaded per variant. The gold-plating on this HLF variant targets longer mating-cycle applications. The push-pull fastening relies on receptacle friction and guide features for lateral retention; verify the application does not impose sustained vibration normal to the board plane.
Compliance
The housing carries a UL94 V-0 flammability rating suitable for industrial and commercial equipment enclosures. No RoHS, REACH, or UL agency code appears in the listing; confirm the full material declaration from Amphenol FCI directly.
