The 0.40 mm pitch drives the board footprint – the contact pads are spaced tightly, so the PCB layout must match the Hirose recommended land pattern to avoid solder bridging during reflow. ## Pick and Place compatibility for SMT assembly This is standard for high-volume SMT lines – the tape-and-reel packaging (Cut Tape and Tape & Reel options) feeds directly into the pick-and-place machine without manual handling. The gold contact finish at 1.97 µinch thickness provides a corrosion-resistant mating surface for signal-level currents.","metaTitle":"Hirose DF40TC(4.0)-50DS-0.4V(51) – 0.40 mm Pitch, 50-Pin","metaDescription":"Hirose DF40TC(4.0)-50DS-0.4V(51) – 0.40 mm pitch, 50-position, 4 mm mated stack height receptacle from the DF40 series.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Board-to-Board Connectors"],"specifications":{"Pitch":"0.016\\\" (0.40mm)","Series":"DF40","Features":"Pick and Place","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Active","Manufacturer":"Hirose Electric Co Ltd","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","lifecycle_stage":"unknown","Height Above Board":"0.154\\\" (3.90mm)","Base Product Number":"DF40TC","Number of Positions":"50","Mated Stacking Heights":"4mm","Contact Finish Thickness":"1.97µin (0.050µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6bcbeafbf2e74799998376310e806237.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the stacking height of DF40TC(4.0)-50DS-0.4V(51)?","answer":"The mated stacking height is 4 mm."},{"question":"Is DF40TC(4.0)-50DS-0.4V(51) compatible with pick-and-place assembly?","answer":"Yes, the connector includes a Pick and Place feature, and it is supplied in Tape & Reel packaging for automated SMT placement."},{"question":"What is the part status of DF40TC(4.0)-50DS-0.4V(51) – is it active or obsolete?","answer":"The part is active and in production.
