It uses a 0.020\" (0.50mm) pitch and surface-mount termination, with a mated stacking height of 5mm. This part is now obsolete per the manufacturer's lifecycle status. ## What the 5mm Stacking Height and 0.50mm Pitch Mean for Your Layout The 0.50mm pitch, combined with 40 positions across two rows, defines the board footprint width and the routing channel density underneath the connector. At this pitch, trace escape from inner rows requires via-in-pad or dog-bone fanout on the inner layer.","metaTitle":"Hirose DF12(5.0)-40DP-0.5V(86) Header, 40 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12(5.0)-40DP-0.5V(86) 40-position, 0.50mm pitch, dual-row SMT header with 5mm stacking height, gold plating.","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":"0.169\\\" (4.30mm)","Number of Positions":"40","Mated Stacking Heights":"5mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12(5.0)-40DP-0.5V(86)/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy DF12(5.0)-40DP-0.5V(86) available via RFQ confirmation?","answer":"The DF12(5.0)-40DP-0.5V(86) is an obsolete part, so stock is found in the surplus and independent broker channel, not through factory franchise lines."},{"question":"Is DF12(5.0)-40DP-0.5V(86) obsolete?","answer":"Yes, the DF12(5.0)-40DP-0.5V(86) is marked obsolete by Hirose."},{"question":"What is the mated stacking height of DF12(5.0)-40DP-0.5V(86)?","answer":"The mated stacking height is 5mm.
