Product details

The Hirose DF37B-20DP-0.4V(53) is a 20-position header from the DF37 series, using outer shroud contacts on a 0.40mm pitch in a dual-row layout. It's designed for board-to-board mezzanine stacking where the mated height is 0.98mm — tight for compact handheld or module-to-motherboard interconnects. Gold flash plating (2.00µin) on the contacts handles moderate mating cycles typical of internal device connections.

The 0.40mm pitch drives the board footprint — trace escape between pads needs a fine-line PCB fab capable of 0.20mm or tighter trace/space. The 0.75mm height above board is the header's own standoff from its mounting surface.

Plating Grade and Duty Cycle

If your application needs higher cycle life or sees corrosive atmospheres, the sibling DF37B-20DP-0.4V(75) carries 4.00µin gold, which doubles the wear layer at the same pitch, position count, and stack height. That extra thickness buys you more reconnect margin without changing the footprint.

Frequently asked questions

What is the pitch of DF37B-20DP-0.4V(53)?

The pitch is 0.016" (0.40mm), dual-row. That 0.40mm centerline drives the PCB footprint and trace escape routing — verify your board fab can handle the fine pitch before committing the layout.

What is the mated stacking height for DF37B-20DP-0.4V(53)?

The mated stacking height is 0.98mm. That's the total z-height from the header's PCB to the mating receptacle's PCB when fully mated. The header itself sits 0.75mm above its own board.
