The 0.50mm pitch is standard for the DF12 series, so any replacement candidate must match that pitch exactly to avoid a board respin. ## Mated stacking heights and board spacing The DF12A-30DS-0.5V(81) supports three mated stacking heights: 3.5mm, 4mm, and 5mm. That range gives the board designer flexibility in z-axis clearance — a 3.5mm stack for tight enclosures, 5mm for more component clearance on the underside. ## Contact finish and termination Gold-plated contacts with 8.00µin thickness. That's a moderate gold flash — adequate for the mating cycle life of a typical board-to-board interconnect in a production assembly, but not designed for repeated field disconnect. The surface mount termination and board guide feature simplify pick-and-place alignment.","metaTitle":"DF12A-30DS-0.5V(81) Obsolete — Hirose DF12 30-Pin 0.5mm","metaDescription":"Hirose DF12A-30DS-0.5V(81) 30-position, 0.50mm pitch board-to-board receptacle.
