The FCI 87916-419HLF is a 19-circuit, single-row unshrouded header from the BERGSTIK® II series, built on the industry-standard 0.100" (2.54mm) pitch. The 100.0µin (2.54µm) tin finish on the mating contacts provides a durable, cost-effective interface for moderate-cycle applications — think test fixtures, internal board-to-board jumpers, or prototyping where gold plating isn't justified. Rated at 5A per contact and 110V, it handles signal and low-power distribution without the cost premium of a shrouded or high-current header.
Pitch and Footprint — Drops Into Standard 0.100" Layouts
The 0.100" (2.54mm) pitch is the de facto standard for breadboard-compatible headers and perfboard prototyping.
Plating and Current — Tin for Cost-Effective Signal Duty
Tin plating on both the mating contact and the solder post keeps the per-unit cost low, but the 100.0µin (2.54µm) thickness is a heavy deposit — it resists fretting corrosion better than thin flash tin in applications with moderate vibration or thermal cycling. The 5A per-contact rating is generous for signal lines; you can also use it for low-current power distribution without pushing the temperature rise.
Mechanical and Compliance
Overall contact length is 1.058" (26.87mm), with a mating length of 0.830" (21.08mm) and a post length of 0.128" (3.25mm) — the short post is meant for standard-thickness PCBs, not backplane press-fit. The insulation height is 0.100" (2.54mm), keeping the mated profile low.
No official cross-reference or direct replacement is on record, but the standard 0.100" pitch means any 19-position unshrouded header with the same pitch and tin plating is a functional equivalent for prototyping — confirm the mating contact length for your stack height.
