The 0.016\" (0.40mm) pitch and 1.14mm above-board height make it a compact interconnect for tight stack-up budgets. ## Stack Height Flexibility This plug supports six mated stacking heights: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm. That range lets a single board layout accommodate different mezzanine gaps by swapping the receptacle height — no footprint change needed. The 0.40mm pitch keeps the board routing dense, so the stack height choice is the main variable for z-axis clearance. No through-hole posts — the SMT pads and solder retention take the mechanical load. ## Position-Count Sibling Comparison The DF40C-10DP-0.4V(51) is the 10-position sibling at the same 0.40mm pitch and 1.14mm height.","metaTitle":"Hirose DF40C-12DP-0.4V(58) Plug, 12 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-12DP-0.4V(58) plug, 12 positions, 0.40mm pitch, gold contacts, SMT with solder retention.
