The Amphenol 86503-448HLF is a 48-position, dual-row unshrouded male pin header from the BERGSTIK® II series, the workhorse 0.100-inch pitch board-to-board interconnect family. The 0.100" (2.54mm) pitch and 0.100" row spacing give a standard grid that matches decades of legacy PCB layouts and the matching BERGSTIK II receptacle. Rated 5 A per contact with a 110 V voltage rating, it sits comfortably in signal and moderate-power board-stacking applications inside enclosures where the UL94 V-0 housing meets the flame rating requirement.
The 0.250" (6.35mm) mating pin length gives enough engagement depth for standard BERGSTIK II receptacles without bottoming out. The 0.120" (3.05mm) solder tail suits standard 0.062" PCBs, and the through-hole termination gives a mechanically robust joint that stands up to vibration better than an SMT equivalent of the same pitch.
