The FCI 79821-438HLF is a 38-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect on a standard 0.100" (2.54 mm) pitch.
38 positions loaded across two rows. The 0.100" row spacing matches the pitch, so the footprint is a 0.100" x 0.100" grid.
RoHS compliance is assumed for current production; the manufacturer's documentation covers the full compliance package.
This is the male pin header half of a board-to-board pair. The 0.200" (5.08 mm) solder tail suits standard 0.062" to 0.093" PCB thicknesses. Overall contact length is 0.730" (18.54 mm).
