Its outer shroud contacts and dual-row layout suit dense digital signal interconnects where board spacing is at a premium — think handheld devices, camera modules, or embedded computing stacks. The 0.50mm pitch drives the PCB footprint: trace routing between pads requires a controlled impedance stack-up and fine-line capability, typical of high-density interconnect designs. ## Why the 4mm Stack Height Matters At 4mm mated stack height, this header fits between boards with a tighter Z-axis envelope than the 5mm and 6mm variants in the same DF12E family. The 0.50mm pitch is consistent across the DF12E series, so a layout designed for the 36-position version accepts the 20- or 50-position sibling at the same stack height without a board respin. ## Mating and Termination Check Surface-mount termination means the connector reflows with the board — no through-hole posts, so alignment during placement is critical.","metaTitle":"Hirose DF12E(4.0)-36DP-0.5V(81) Header, 36 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12 series header, 36 positions, 0.50mm pitch, 4mm stack height, gold 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) Cut Tape (CT)","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":"36","Mated Stacking Heights":"4mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12E(4.0)-36DP-0.5V(81)/alternatives.json"},"ai":{"faq":[{"question":"Is the DF12E(4.0)-36DP-0.5V(81) obsolete?","answer":"Yes, this part is obsolete per the manufacturer's product status.
