Outer shroud contacts provide alignment during mating and protect the terminals from side-load damage, which matters in assemblies where the boards are stacked without a separate guide frame. ## What the Stacking Height and Pitch Mean for Your Board Layout The 0.50mm pitch forces the trace fan-out to use fine-line routing or via-in-pad on the inner rows; expect to drop to micro-vias if routing all 36 signals out of a single layer. ## Where the Real Stock Is — and How We Quote It Because this part is obsolete, we don't maintain a shelf stock. We source it against your RFQ — we'll check our network of independent distributors and brokers for real, date-coded inventory. No commitment to ship same-day; this is a locate-and-quote part for legacy repair or last-time-buy coverage.","metaTitle":"Hirose DF12D(4.0)-36DP-0.5V(81) Header, 36 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12D(4.0)-36DP-0.5V(81) 36-position SMT header, 0.50mm pitch, 4mm 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)","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":"0.130\\\" (3.30mm)","Number of Positions":"36","Mated Stacking Heights":"4mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy DF12D(4.0)-36DP-0.5V(81) available via RFQ confirmation?","answer":"DF12D(4.0)-36DP-0.5V(81) is obsolete and not stocked on the shelf."},{"question":"What is the stacking height for DF12D(4.0)-36DP-0.5V(81)?","answer":"The mated stacking height is 4mm, with a height above board of 0.130\" (3.30mm) for the unmated header."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/DF12D~14.0~2-36DP-0.5V~181~2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/hirose-electric-co-ltd/DF12D~14.0~2-36DP-0.5V~181~2 when reusing this data.
