The Amphenol 68498-424HLF is a 24-position, single-row, unshrouded male pin header from the BERGSTIK® II series. It uses a 0.100" (2.54 mm) pitch, the standard grid for legacy through-hole PCB layouts, and mounts at a right angle to the board. This connector is designed for board-to-board interconnect applications where a low-profile, unshrouded header mates with a standard 0.100" pitch receptacle.
Key Specs and What They Mean
The 24 positions are fully loaded, so the circuit count on the BOM must match exactly. The 0.100" (2.54 mm) pitch is the de facto standard for many ribbon-cable and discrete-wire receptacles, making board layout straightforward. The 5 A per-contact rating is the current ceiling at the stated temperature rise — fine for signal and light power duty, but derate above ambient if the enclosure runs hot. The tin-on-tin contact finish (100.0 µin on the mating side) keeps cost low but limits mating cycles compared to gold; this header is best suited for semi-permanent connections or low-cycle field service. The right-angle orientation routes the header parallel to the PCB, which saves vertical space inside an enclosure and is common for board-edge or mezzanine-style stacking. The UL94 V-0 rated black housing means the connector meets the flame-retardancy requirement for equipment inside an enclosure. The push-pull fastening type means no locking latch — the retention comes from the friction of the pin-and-receptacle interface.
Mating and Termination
This unshrouded header mates with any standard 0.100" (2.54 mm) pitch female receptacle housing that accepts 0.025" square pins — a common interface across the BERGSTIK and compatible series. The solder termination is through-hole, with a 0.220" (5.58 mm) post length for the PCB side and a 0.230" (5.84 mm) mating pin length. The square pin profile ensures reliable four-point contact in the mating receptacle.
