The 0.020\" (0.50mm) pitch packs 20 circuits into a compact footprint — the tight pitch means the board layout needs controlled impedance routing if used for high-speed signals, and the via keep-out zone around each pad is minimal. This receptacle accepts the matching DF12 series plug header (the male counterpart with the same 0.50 mm pitch and position count) to form a board-to-board interconnect. The mated stacking height is configurable: the receptacle alone sits 0.106\" (2.70mm) above the board, and the mated assembly supports 3.5mm, 4mm, or 5mm stack heights depending on which plug height variant is paired. That flexibility lets the same receptacle serve different board spacing requirements across a product family — a single BOM line for the receptacle while the plug height changes per assembly. ## Board Layout and Assembly Considerations","metaTitle":"Hirose DF12-20DS-0.5V(80) 20-Position 0.50mm Receptacle","metaDescription":"Hirose DF12-20DS-0.5V(80) 0.50mm pitch 20-position receptacle, center strip contacts, gold plating, 2.70mm height, supports 3.5/4/5mm stack heights.","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":"Tube","Features":"Board Guide, Solder Retention","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"0.106\\\" (2.70mm)","Number of Positions":"20","Mated Stacking Heights":"3.5mm, 4mm, 5mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ec3a1e7b7e2032976a5195b0ee91977e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the stacking height of DF12-20DS-0.5V(80)?","answer":"The DF12-20DS-0.5V(80) receptacle supports mated stacking heights of 3.5mm, 4mm, or 5mm, depending on which plug height variant is mated with it.
