Product details

Board-stacking selection

The Hirose DF12NC(3.5)-40DP-0.5V(51) is a 40-position header with outer shroud contacts from the DF12 series, designed for board-to-board mezzanine stacking. The 0.50mm pitch and dual-row layout pack 40 circuits into a compact footprint, while the 3.5mm mated stacking height sets the board spacing in the assembly. Surface-mount termination keeps the profile low at 2.80mm above the board.

The 0.50mm pitch drives a dense board layout; the footprint requires precise SMT placement, not hand-soldering.

Frequently asked questions

What is the mated stacking height of DF12NC(3.5)-40DP-0.5V(51)?

The mated stacking height is 3.5mm. This is the gap between the two PCBs when the header is mated with the matching DF12 receptacle.

What is the pitch of DF12NC(3.5)-40DP-0.5V(51)?

The pitch is 0.50mm (0.020"). This is a fine-pitch connector requiring SMT placement and a matching PCB footprint.
