Board-to-Board Header on a Standard Grid
The Amphenol FCI 67998-116HLF is a 16-circuit, dual-row unshrouded male header from the BERGSTIK II series. It sits on the industry-standard 0.100" (2.54 mm) pitch, making it a drop-in for any PCB laid out on that grid. The through-hole solder tails and 0.100" row spacing match the footprint of the matching receptacle — no surprises when you drop it into a board layout. Rated at 5 A per contact with 30 µ" gold or Gold GXT plating on the mating surface, this header is built for repeated mating cycles in a clean, indoor environment. The UL94 V-0 black housing meets the flame rating required for equipment inside an enclosure.
What the Ratings Mean for the Fit
The 0.100" pitch is the key footprint dimension — it matches the standard 2.54 mm grid, so the board layout engineer can route traces between pads without a custom footprint. The 0.318" mating pin length gives enough reach to engage the receptacle contact beam fully, while the 0.107" post length is sized for a standard 1.6 mm PCB thickness. At 5 A per contact, the current rating is typical for a signal-level header on this pitch. The limiting factor is the temperature rise in the housing, not the contact itself — derate above ambient if you push all 16 circuits at full current. The 30 µ" gold plating supports 200+ mating cycles without contact resistance drift, which matters if this header sees field service or repeated board swaps. Being unshrouded, this header has no polarization key. The mating receptacle must be aligned by the board layout or a separate alignment feature — the push-pull fastening means no locking latch, so it's a straight in-and-out mate.
