The connector stands 0.130\" (3.30mm) above the board and achieves a mated stacking height of 4mm when paired with the matching DF12 receptacle. This geometry suits tight z-height budgets in portable electronics, handheld instruments, and other space-constrained assemblies where two PCBs need a reliable signal interconnect. ## Board Layout Fit — Pitch, Stack Height, and Footprint The 0.50mm pitch drives the board layout — the SMT pads are closely spaced, so the PCB fab must handle fine-pitch registration and solder paste deposition. The 30 positions across two rows give 15 contacts per row, which sets the footprint length at roughly 7.5mm plus keep-out. Gold plating at 8.00µin on the contacts provides corrosion resistance for the expected mating cycle count in consumer and industrial environments — adequate for assembly and occasional rework, not for high-cycle field service.","metaTitle":"Hirose DF12E(4.0)-30DP-0.5V(81) Header, 30 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12 series 30-position header, 0.50mm pitch, 4mm stacking height, gold-plated contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Board-to-Board Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Pitch":"0.020\\\" (0.50mm)","Series":"DF12","Package":"Tape & Reel (TR)","Features":"-","Mounting Type":"Surface Mount","Connector Type":"Header, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"0.130\\\" (3.30mm)","Number of Positions":"30","Mated Stacking Heights":"4mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12E(4.0)-30DP-0.5V(81)/alternatives.json"},"ai":{"faq":[{"question":"What is the mated stacking height of the DF12E(4.0)-30DP-0.5V(81)?","answer":"The mated stacking height is 4mm when mated with the corresponding DF12 series receptacle.
