The 0.50mm pitch keeps the footprint compact, but it also means the routing channels between pads are narrow; a 2-row, 20-position layout fits in about 5mm of board edge. ## Obsolete — what that means for sourcing The DF12(3.0)-20DP-0.5V(86) is marked Obsolete. That means the factory has stopped production, and the only available stock sits in the surplus and broker channel. ## What crosses when the original is dry Because the DF12 series uses the same 0.50mm pitch and 2-row layout across multiple stack heights, a sibling like the DF12(5.0)-20DP-0.5V(86) (5mm stack height) shares the same footprint and pinout — but the taller gap means it won't fit a 3mm enclosure. If your mechanical stack-up has any z-height margin, a 3.5mm or 4mm variant from the same DF12 family may work, but there is no drop-in 3mm replacement from Hirose. The only way to match the original 3mm height is to source the exact obsolete code or redesign the board for a current-production mezzanine connector.","metaTitle":"Hirose DF12(3.0)-20DP-0.5V(86) Header, 20 pos, 0.50mm","metaDescription":"Hirose DF12(3.0)-20DP-0.5V(86) 20-position header, 0.50mm pitch, 3mm mated stack 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) Cut Tape (CT)","Features":"Board Guide, Solder Retention","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":"0.091\\\" (2.30mm)","Number of Positions":"20","Mated Stacking Heights":"3mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy DF12(3.0)-20DP-0.5V(86)?","answer":"This part is obsolete and sourced through the independent distribution channel.
