The 68023-403HLF is a 3-position, single-row, unshrouded BergStik® II header from Amphenol ICC (FCI). It uses the standard 0.100" (2.54mm) pitch that matches breadboard and perfboard layouts. The right-angle through-hole termination places the pins parallel to the board surface, which suits edge-mounted connections in mezzanine or daughtercard stacks. Tin plating on both the mating surface and the solder tails keeps the per-unit cost low; the 5A per-contact rating gives it headroom for a local power rail or low-current drive alongside signal lines.
What the key ratings mean for the fit
The 0.100" pitch is the de facto standard for 0.1-inch grid prototyping — no footprint adjustment needed. The 5A per-contact rating is generous for a 2.54mm pitch unshrouded header; it can carry a 5V rail or a low-power fan/motor line, not just logic signals. The tin mating finish is cost-effective but wears faster than gold — expect a limited number of mating cycles, so this header is best for semi-permanent connections or infrequent field service. The UL94 V-0 housing meets the flame-rating requirement for equipment inside an enclosure.
Mating and board layout
This unshrouded header mates with any standard 0.100" pitch female socket housing or crimp receptacle — no proprietary keying or locking ramp. The right-angle orientation and 0.305" (7.75mm) post length give enough standoff for a wire-to-board connector on the mating side. The 0.136" (3.45mm) mating pin length provides a solid wipe inside the receptacle contact. The single-row layout keeps the board footprint narrow — useful for tight edge clearance.
