Board-to-Board Mezzanine Connector for Tight Stack Heights
The Hirose DF12NC(3.0)-14DS-0.5V(51) is a 14-position receptacle from the DF12 series, designed for board-to-board mezzanine stacking. It uses a 0.50mm pitch and a center strip contact arrangement, which tells you this is a parallel-board interconnect — not a wire-to-board or edge-card type. The mated stacking height is 3mm, a common gap for compact handheld or embedded systems where every millimeter of z-height matters. Gold-plated contacts with 8.00µin thickness handle moderate mating cycles without fretting corrosion, typical for internal board stacks that aren't frequently reconnected.
No end-of-life notice or last-time-buy on record. The Tape & Reel packaging feeds standard pick-and-place lines.
Surface Mount Assembly and Footprint Notes
The 0.50mm pitch requires a tight pad layout — verify your board house can hold the registration tolerance. The center strip contacts mean the mating plug (DF12 series header) aligns on the board's centerline, not the edge.
