Obsolete — Sourcing Path for This 40-Position Mezzanine Header
The DF12E(3.5)-40DP-0.5V(81): This is a 40-position, 0.50mm pitch header with outer shroud contacts, designed for a 3.5mm mated stack height — a common mezzanine gap for compact portable or embedded systems. 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Because this part is Obsolete, it is not stocked for immediate shipment.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.
