The gold-plated contacts (8.00µin thickness) suit moderate mating-cycle duty in signal-level applications. The 0.50mm pitch and 2-row layout (40 positions total) demand a tight board footprint — verify the keep-out zone and trace escape before committing the layout. Surface-mount termination with tape-and-reel packaging supports automated pick-and-place assembly. ## Sourcing an Obsolete Part Because this part is Obsolete, it is not stocked for immediate shipment. For a pin-compatible alternative, the buyer should verify the pitch, stack height, and position count against other DF12 variants.","metaTitle":"DF12E(3.5)-40DP-0.5V(81) Hirose Board-to-Board Connector","metaDescription":"Hirose DF12E(3.5)-40DP-0.5V(81) 40-position, 0.50mm pitch board-to-board header, 3.5mm stack height.
