BergStik II 24-Position Unshrouded Header
The Amphenol FCI 91276-124HLF is a 24-position, single-row, unshrouded male header from the BergStik II series. It uses the standard 0.100-inch (2.54 mm) pitch, making it a drop-in fit for legacy breadboard layouts and common 0.100-inch grid PCBs. The through-hole solder termination and push-pull fastening are straightforward for manual or wave-solder assembly. Rated 5 A per circuit at 110 V, this header is sized for signal-level and low-power interconnects — think logic-level I/O, control lines, or sensor inputs, not a main power rail.
Contact Plating and Duty
The mating surface carries 30.0 µin (0.76 µm) of gold over phosphor bronze. That gold thickness supports repeated mating cycles without the contact resistance drift you'd see with tin — a practical advantage if this header lives in a board that gets reworked or tested across multiple harness swaps. The 5 A per-contact rating holds at the stated voltage; for continuous duty near that limit, keep the ambient temperature inside the UL94 V-0 housing's envelope.
Sourcing and Lifecycle
This part carries an Active lifecycle status — no end-of-life notice, no last-time-buy clock. No official successor or cross-reference is recorded; the 91276-124HLF is the current production part for this position count and pitch.
