It uses a 0.50 mm pitch, dual-row layout with center strip contacts — the mating half is the corresponding DF12 header. The gold-plated contacts and 3 mm mated stacking height make this part suited for compact parallel-board stacking in portable electronics, handheld instruments, and other space-constrained assemblies where the z-height budget is tight. ## What the 0.50 mm pitch and 3 mm stacking height mean for the build The 0.50 mm pitch is tight — it drives the PCB routing density and limits the current per contact to the low-signal range. The 3 mm mated stacking height is the z-height between the two parallel boards; it's a fixed dimension, so the enclosure and component clearance on the underside of the top board must account for it.","metaTitle":"Hirose DF12B(3.0)-20DS-0.5V(86)","metaDescription":"Hirose DF12B(3.0)-20DS-0.5V(86) receptacle, 20 positions, 0.50mm pitch, 3mm stacking 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":"Solder Retention","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"0.087\\\" (2.20mm)","Number of Positions":"20","Mated Stacking Heights":"3mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12B(3.0)-20DS-0.5V(86)/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the DF12B(3.0)-20DS-0.5V(86) and how do I get a price?","answer":"The DF12B(3.0)-20DS-0.5V(86) is obsolete and sourced through independent distribution."},{"question":"What is the stacking height of the DF12B(3.0)-20DS-0.5V(86)?","answer":"The mated stacking height is 3 mm.
