The Amphenol 87900-426HLF is a 26-position, dual-row BERGSTIK® II unshrouded male pin header on the standard 0.100" (2.54 mm) pitch. This is the workhorse square-pin header used for prototyping, mezzanine stacking, and general-purpose board interconnect where the unshrouded design gives flexibility in mating with standard 0.100" pitch receptacles.
Position count and footprint
26 positions across two rows at 0.100" row spacing gives a 13-by-2 pin grid that matches the standard 0.100" x 0.100" DIP footprint. The 0.720" (18.29 mm) mating pin length provides good wipe depth in standard box headers and IDC receptacles, while the 0.120" (3.05 mm) solder tail suits 0.062" to 0.093" PCBs without trimming.
5 A per contact is a signal-level rating — adequate for logic-level power and I/O lines, but not a power bus.
