The Amphenol FCI 86503-422HLF is a 22-position dual-row unshrouded male header from the BergStik® II series, on the standard 0.100" (2.54mm) pitch. It terminates through-hole with solder, mates with the matching BergStik II receptacle housing via a push-pull fastening, and carries tin-plated phosphor bronze contacts rated 5A per circuit at the stated voltage rating of 110V.
The 22-position count at a 0.100" pitch and dual-row layout places this header in the middle of the BergStik II range — enough positions for a parallel data bus or a ribbon-cable interface without the board space of a 34- or 40-position header. The 0.120" (3.05mm) solder-tail length suits standard 0.062" (1.6mm) PCBs; the overall contact length of 0.470" (11.94mm) and mating length of 0.250" (6.35mm) are typical for this class.
