Product details

0.40mm-Pitch Board-to-Board Header for Tight Stack Heights

The Hirose DF37B-30DP-0.4V(53) is a 30-position header from the DF37 series, designed for parallel board-to-board stacking where the z-height budget is tight.

Contacts are gold-plated at 2.00µin (0.051µm) — a thin flash that keeps contact resistance low for the initial mate. For applications requiring frequent reconnection cycles, a thicker gold layer would be needed to avoid exposing the nickel underplate.

The DF37B series offers the same 0.40mm pitch and 0.75mm height in 24-position (DF37B-24DP-0.4V(53)) and 40-position (DF37B-40DP-0.4V(51)) variants. The 30-position DF37B-30DP-0.4V(53) sits between them — pick the position count that matches the signal or power lines in your board stack. The (53) suffix indicates Tape & Reel and Cut Tape packaging, while the (51) suffix adds Digi-Reel as an option; the connector itself is electrically and mechanically identical between the two suffix codes.
