The header mates with any DF12 series receptacle that matches the 20-position, 0.50 mm pitch layout. Surface-mount termination requires reflow soldering; the Tape & Reel packaging suits automated pick-and-place assembly.","metaTitle":"Hirose DF12E(4.0)-20DP-0.5V(81) 20-Pin 0.5mm Header","metaDescription":"Hirose DF12E(4.0)-20DP-0.5V(81) 0.5mm pitch board-to-board header, 20 positions, 2 rows, 4mm stacking 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)","Features":"-","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":"20","Mated Stacking Heights":"4mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12E(4.0)-20DP-0.5V(81)/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for DF12E(4.0)-20DP-0.5V(81)?","answer":"A pin-compatible alternative would need to match the 20-position, 2-row, 0.50 mm pitch, 4 mm stacking height, and surface-mount footprint — confirm fit against the specific receptacle and board layout before substituting."},{"question":"What is the stacking height of DF12E(4.0)-20DP-0.5V(81)?","answer":"The mated stacking height is 4 mm.
