The through-hole solder tails are 0.360" (9.14 mm) long, which suits standard PCB thicknesses around 1.6 mm with enough protrusion for a reliable solder fillet.
Board-to-board style and unshrouded design
Listed as a board-to-board style connector, this header is designed to mate with a dual-row 0.100" pitch receptacle — typically a BERGSTIK II socket or a standard IDC socket with the same 70-position count. Because it is unshrouded, there is no polarization key; the mating receptacle's housing provides alignment. With an overall contact length of 0.820" (20.83 mm), the total stack height from board to mated interface is determined by the receptacle's own insulation height plus the 0.360" (9.14 mm) mating pin length.
