Product Introduction
The Amphenol 92417-424HLF is a 24-circuit, dual-row unshrouded header from the BergStik II series, on the standard 0.100" (2.54mm) pitch. It is a board-to-board interconnect, through-hole soldered, with tin-plated phosphor bronze contacts rated at 5A per circuit and 110V. The black UL94 V-0 housing and push-pull fastening make it a straightforward, cost-effective choice for internal PCB stacking or wire-to-board applications where a shrouded header is not required.
Key Ratings and What They Mean for Fit
The 0.100" (2.54mm) pitch is the industry-standard breadboard-compatible spacing, which means the PCB footprint is a known quantity and the header mates with a wide range of standard 0.100" pitch receptacles. The 24 positions, all loaded, match the circuit count on the BOM directly — no unpopulated positions to account for. The 5A per-contact rating is the current ceiling at the stated voltage; for signal-level duty this is ample headroom, but for power distribution it sets the limit per pin, and the total current through the header is the sum of all active circuits, so thermal management at the board level should be considered if many circuits are loaded near the maximum. The tin mating finish (100.0µin / 2.54µm) is cost-effective but is best suited for applications with a low number of mating cycles — typically under 25 cycles — as tin is more prone to fretting corrosion than gold under vibration or frequent disconnect/reconnect.
Deployment Context
As an unshrouded header, the 92417-424HLF is a good fit for board-to-board stacking or as a pin header for a mating IDC socket or crimp receptacle, but the exposed pins mean the mating connector must be aligned manually — there is no polarization keying or shroud to prevent mis-mating. The through-hole solder termination provides a mechanically robust joint for the board assembly line.
