Product details

0.40mm Pitch Header for Tight Board-Stacking

The Hirose DF37B-10DP-0.4V(53) is a 10-position, dual-row header from the DF37 series, designed for parallel board-to-board stacking where board real estate is at a premium. The 0.016" (0.40mm) pitch forces a tight pad layout — expect 0.20mm to 0.25mm pad width on the footprint, with trace escape routing between pads requiring a controlled impedance stack if signals run above a few hundred MHz.

It is ROHS3 Compliant, which covers the EU RoHS directive's current substance restrictions.

Frequently asked questions

What is the pitch of DF37B-10DP-0.4V(53)?

The pitch is 0.016" (0.40mm), which is the center-to-center spacing between adjacent contacts. This tight pitch drives the PCB footprint — expect fine-pitch SMT pads and narrow trace escapes between them.

What is the stacking height of Hirose DF37B-10DP-0.4V(53)?

The mated stacking height is 0.98mm. That's the total z-height from the bottom board's top surface to the top board's bottom surface when the header is mated with its matching receptacle. Check this against your component keep-out zones on the underside of the top board.
