The FCI 92417-434HLF is a 34-position, dual-row BergStik II unshrouded header on the standard 0.100" (2.54mm) pitch. Typical use is as a board-to-board signal interconnect — the 5A per-contact rating and tin-on-tin contact system place it in the cost-optimized segment of the BergStik II family, suited for internal connections where frequent mating cycles aren't the primary concern.
What the key specs mean for fit
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing are the industry-standard grid — your board footprint is the same as any standard 34-pin DIP or IDC pattern, so layout is straightforward. Overall contact length is 0.530" (13.46mm), with a 0.110" (2.79mm) solder tail — check your board thickness and through-hole plating depth against that tail length for a proper solder fillet. The limiting factor isn't the contact itself — it's the temperature rise in the unshrouded plastic housing when all 34 circuits are loaded near max. For a 34-position header carrying 5A on every pin, you'd be pulling 170A total through the connector; derate per the application note if you're running more than a handful of circuits at full current.
