Hirose DF40C-60DP-0.4V(51) — 60-Position, 0.40mm Pitch Mezzanine Plug
The Hirose DF40C-60DP-0.4V(51) is a 60-position plug with outer shroud contacts from the DF40 series of fine-pitch board-to-board connectors. It uses a 0.016" (0.40mm) pitch in a dual-row layout, with gold-plated contacts (2.00µin thickness) for reliable signal connections in compact electronic assemblies.
Stacking Height Range and Board Spacing
The mated stacking height options — 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm — cover the common board-to-board gaps used in compact handheld devices, camera modules, and portable electronics. The 0.045" (1.14mm) height above board keeps the profile low, which matters when the total z-height budget is tight. The stacking height is set by the matching receptacle; the plug itself stays at a fixed 1.14mm above the PCB.
60 Positions — Mid-Range in the DF40C Family
At 60 positions, this plug sits between the 50-position DF40C-50DP-0.4V(51) and the 70-position DF40C-70DP-0.4V(51), all sharing the same 0.40mm pitch, 2-row layout, gold plating, and solder retention. The 80-position DF40C-80DP-0.4V(51) extends the family further. The position count is the only variable that changes the BOM line — pitch, footprint, and mating receptacle family are identical across these siblings, so swapping to a different position count means a new PCB layout.
