It uses a 0.020\" (0.50mm) pitch in a dual-row layout, with a mated stacking height of 3mm — a fixed dimension that sets the z-height budget between parallel PCBs. ## What the 3 mm Stack Height and Solder Retention Mean for Assembly The 3mm mated stacking height is a fixed value — not adjustable — so the board-to-board spacing is locked once this connector is specified. The solder retention features are integrated into the SMT footprint to prevent the connector from lifting off the pad during reflow or under mechanical stress, which is a practical advantage for high-density mezzanine stacks where rework access is limited. The 0.50mm pitch requires careful PCB layout to maintain routing clearance between pads.","metaTitle":"Hirose DF12B(3.0)-50DS-0.5V(86), 50-pos 0.50mm Receptacle","metaDescription":"Hirose DF12B(3.0)-50DS-0.5V(86) receptacle, 50 positions, 0.50mm pitch, 3mm stack height, gold contacts, solder retention.","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":"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":"0.087\\\" (2.20mm)","Number of Positions":"50","Mated Stacking Heights":"3mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12B(3.0)-50DS-0.5V(86)/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for DF12B(3.0)-50DS-0.5V(86)?","answer":"A pin-compatible alternative within the Hirose DF12 series should be evaluated — confirm the 0.50mm pitch, 50 positions, dual rows, and 3mm mated stack height match the board footprint before specifying."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/DF12B~13.0~2-50DS-0.5V~186~2","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/DF12B~13.0~2-50DS-0.5V~186~2 when reusing this data.
