Solder retention features on the body help keep the part seated during SMT reflow. ## What the 4mm Stack Height and 0.50mm Pitch Mean for Your Layout The 0.50mm pitch drives the PCB routing density: you'll need fine trace-and-space capability to fan out 50 signals from the footprint. The two-row arrangement gives 25 contacts per row, so the footprint is roughly 12.5mm long (25 positions × 0.50mm) plus the keep-out at each end. The outer shroud contacts add some width to the body but also provide mechanical alignment and pin protection during mating — useful for automated assembly where misalignment can damage fine-pitch pins.","metaTitle":"Hirose DF12NB(4.0)-50DP-0.5V(51) 50-Pos 0.50mm Header","metaDescription":"Hirose DF12NB(4.0)-50DP-0.5V(51) 50-position, 0.50mm pitch header, outer shroud contacts, 4mm mated stack height, gold plating, SMT, solder retention.","metaKeywords":null},"attributes":{"series":"DF12","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking 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":"Header, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Height Above Board":"0.130\\\" (3.30mm)","Base Product Number":"DF12N","Number of Positions":"50","Mated Stacking Heights":"4mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8800","priceTiers":[{"qty":1,"price":"$1.88000","currency":"USD"},{"qty":10,"price":"$1.63800","currency":"USD"},{"qty":25,"price":"$1.56800","currency":"USD"},{"qty":50,"price":"$1.53320","currency":"USD"},{"qty":100,"price":"$1.46350","currency":"USD"},{"qty":250,"price":"$1.32412","currency":"USD"},{"qty":500,"price":"$1.21958","currency":"USD"},{"qty":1000,"price":"$1.04535","currency":"USD"},{"qty":2000,"price":"$1.01051","currency":"USD"},{"qty":3000,"price":"$0.97566","currency":"USD"},{"qty":5000,"price":"$0.92688","currency":"USD"},{"qty":10000,"price":"$0.90597","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/56abd4eecf06f2004ec36cd39c1d5304.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12NB(4.0)-50DP-0.5V(51)/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy DF12NB(4.0)-50DP-0.5V(51) available via RFQ confirmation?","answer":"Availability is confirmed at quote time — submit an RFQ for current pricing and lead time."},{"question":"What is the exact mated stacking height of DF12NB(4.0)-50DP-0.5V(51)?","answer":"The mated stacking height is 4mm.
