The 0.50mm pitch keeps the board footprint tight — each row of 10 contacts on 0.50mm centers means the overall width across both rows is about 4.5mm, leaving room for routing traces between pads on a dense PCB. The 3.5mm mated stacking height is set by the (3.5) in the order code — the header stands 2.80mm above the board surface, and the matching receptacle accounts for the remaining gap. A 20-position board like this one matches a 20-circuit bus; stepping to a 10-position sibling halves the row length but keeps the same pad geometry. ## Lifecycle Status — Obsolete, Sourced to Order This DF12D(3.5)-20DP-0.5V(81) is listed as Obsolete by Hirose.","metaTitle":"Hirose DF12D(3.5)-20DP-0.5V(81) Header, 20 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12 series header, 20 positions, 0.50mm pitch, 2 rows, gold contacts, 3.5mm stack height.","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","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":"0.110\\\" (2.80mm)","Number of Positions":"20","Mated Stacking Heights":"3.5mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12D(3.5)-20DP-0.5V(81)/alternatives.json"},"ai":{"faq":[{"question":"What is the stacking height of DF12D(3.5)-20DP-0.5V(81)?","answer":"The mated stacking height is 3.5mm, with the header standing 0.110\" (2.80mm) above the board surface."},{"question":"What is the mating connector for DF12D(3.5)-20DP-0.5V(81)?","answer":"This header mates with a matching DF12 series receptacle of the same 20-position count and 0.50mm pitch.
