Product details

Board Layout Fit: 0.40mm Pitch and 100 Positions

The Hirose DF40C-100DP-0.4V(51) is a 100-position plug with outer shroud contacts from the DF40 series, designed for board-to-board mezzanine stacking. The 0.016" (0.40mm) pitch on two rows packs 100 circuits into a compact footprint — the tight pitch demands careful trace escape routing and via fanout on the PCB, especially for dense signal layers.

Stack Height Options and Mating Flexibility

This plug supports six mated stacking heights: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm. The height is set by pairing the plug with the matching receptacle (DF40C-100DS-0.4V(51) or equivalent) — the same PCB footprint works across all heights, so you can change board spacing without a layout revision.

For applications requiring frequent field reconnection, a thicker gold layer would be preferable; here the thin flash keeps cost down while maintaining corrosion resistance in the mated state.

Position Count Comparison Across the DF40C Subfamily

Within the DF40C subfamily, the 100-position DF40C-100DP-0.4V(51) sits at the top of the position range.

Frequently asked questions

What is the mating receptacle for DF40C-100DP-0.4V(51)?

The mating receptacle is the DF40C-100DS-0.4V(51) or any DF40C-series 100-position receptacle with the same 0.40mm pitch. The plug and receptacle pair to achieve one of the six supported stack heights.

What are the stack height options available with DF40C-100DP-0.4V(51)?

Six stack heights are supported: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm. The height is determined by the receptacle variant chosen; the plug footprint is common across all.
