The mated stacking height is 3mm, making it a board-to-board mezzanine interconnect for parallel PCB stacking at a fixed 3mm gap. The 0.50mm pitch is tight — board layout must account for routing one trace between pads on standard PCB fab capabilities. ## Replacement and Cross-Reference The closely related DF12(3.0)-40DS-0.5V(80) shares the same 40-position count, 0.50mm pitch, and 3mm stacking height, but the suffix difference (86 vs 80) may indicate a packaging or material variant. Verify footprint and mating compatibility against your existing board layout before substituting.","metaTitle":"Hirose DF12B(3.0)-40DS-0.5V(86) Receptacle, 40 Pos, 0.50mm","metaDescription":"Hirose DF12B(3.0)-40DS-0.5V(86) receptacle, 40 positions, 0.50mm pitch, 3mm stacking height.
