The Amphenol/FCI 93939-144HLF is a 44-position, dual-row BergStik® II unshrouded header on a 0.100" (2.54 mm) pitch. It is a through-hole, right-angle male pin header with square pins, designed for board-to-board interconnect where a solder-terminated, unshrouded interface is needed.
The 0.100" (2.54 mm) pitch and 0.100" row spacing create a standard 0.100" x 0.100" grid. This is the footprint of a classic BergStik II or equivalent square-pin header strip. The 44 positions are loaded fully across two rows of 22 each. For a board layout engineer, this means the footprint is a 2 x 22 array of 0.025" square holes on a 0.100" grid, with the right-angle bend placing the pin tails 0.120" (3.05 mm) below the board surface.
