Gold plating on the contacts (8.00µin) handles the repeated mating cycles a field-serviceable device demands; the solder retention feature keeps the connector anchored through reflow without shifting. ## What the 3mm Stack Height and Solder Retention Mean on the Line The 3mm mated stacking height sets the board-to-board gap — your mezzanine design must allocate exactly that z-height between the two PCBs. The solder retention feature adds holding force during reflow, which reduces the chance of the connector lifting or skewing on the paste. Surface-mount termination with gold-over-nickel contacts (8.00µin gold) gives a reliable interconnect for moderate-cycle applications — think test fixtures, handheld terminals, or instrumentation where the boards need to separate for service.","metaTitle":"Hirose DF12B(3.0)-32DS-0.5V(86) 32-Position 0.50mm","metaDescription":"Hirose DF12 series 32-position receptacle, 0.50mm pitch, 3mm stack height, gold-plated center strip 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) 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":"32","Mated Stacking Heights":"3mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12B(3.0)-32DS-0.5V(86)/alternatives.json"},"ai":{"faq":[{"question":"Is the DF12B(3.0)-32DS-0.5V(86) obsolete?","answer":"Yes, the lifecycle status is Obsolete — Hirose has discontinued production.
