Board-Stacking Header at 0.40mm Pitch
The Hirose DF37C-24DP-0.4V(53) is a 24-position header from the DF37 series, designed for board-to-board mezzanine stacking. The mated stack height is 0.98mm, with the header itself standing 0.030" (0.75mm) above the board — a tight z-height budget for compact handheld or portable electronics.
The 0.75mm height above board means the component sits flush enough to clear tight enclosures or secondary boards. The 0.40mm pitch demands careful trace routing — fine-line PCB capability is expected for fanout between the two rows.
