The 0.50mm pitch packs the 40 circuits into a compact footprint — typical for space-constrained handheld or portable equipment where the mezzanine card sits close to the main board. Gold-plated contacts on the mating interface handle repeated connect cycles without fretting corrosion, and the outer shroud contacts provide alignment and strain relief during mating. The surface-mount termination suits automated pick-and-place assembly, though the bulk packaging means no tape-and-reel feed for high-volume lines — plan for tray or tube handling. ## Obsolete — Sourcing the DF12D(3.5)40DP0.5V80 That means no active factory production — the only channel is surplus inventory or broker stock. ## 0.50mm Pitch, 40 Circuits — Board Layout Fit The 0.50mm pitch drives a dense board footprint — each row of 20 contacts sits on that tight centerline, which means trace routing between pads is narrow and requires careful impedance control for high-speed signals. The 3.5mm mated stack height is fixed by the connector body; the mating receptacle (a Hirose DF12 series female) must match this height exactly — swapping to a 3.0mm or 4.0mm stack variant changes the mezzanine spacing and may not align with the board keep-out zones.","metaTitle":"Hirose DF12D(3.5)40DP0.5V80 Header, 40 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12 series header, 40 positions, 0.50mm pitch, 3.5mm stack height, SMT, gold contacts.
