It uses a 0.016\" (0.40mm) pitch across two rows of center strip contacts, with a mated stacking height of 1.5mm and a height above board of 0.057\" (1.45mm). The gold-plated contacts and solder retention features are designed for reliable SMT assembly in space-constrained, fine-pitch interconnects typical of mobile devices, cameras, and compact modules. The 0.057\" (1.45mm) height above board is the receptacle's own profile on the PCB. ## Solder Retention for Reflow Reliability The solder retention feature provides additional mechanical hold during reflow, reducing the risk of tombstoning or shifting on fine-pitch 0.40mm pads. This is a practical advantage for high-volume SMT lines where placement accuracy and reflow yield are under constant pressure. The DF40B-10DS-0.4V(58) carries an Active product status, with no end-of-life notice on record. It is RoHS compliant.","metaTitle":"Hirose DF40B-10DS-0.4V(58) Receptacle, 10 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40B-10DS-0.4V(58) receptacle, 10 positions, 0.40mm pitch, 1.5mm mated stack height, gold contacts, solder retention.","metaKeywords":null},"attributes":{"series":"DF40","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Pitch":"0.016\\\" (0.40mm)","Series":"DF40","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":"Active","lifecycle_stage":"unknown","Height Above Board":"0.057\\\" (1.45mm)","Base Product Number":"DF40B","Number of Positions":"10","Mated Stacking Heights":"1.5mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7600","stockQuantity":26,"priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.64300","currency":"USD"},{"qty":25,"price":"$0.61720","currency":"USD"},{"qty":50,"price":"$0.60400","currency":"USD"},{"qty":100,"price":"$0.57770","currency":"USD"},{"qty":250,"price":"$0.52520","currency":"USD"},{"qty":500,"price":"$0.47268","currency":"USD"},{"qty":1000,"price":"$0.42016","currency":"USD"},{"qty":2000,"price":"$0.39390","currency":"USD"},{"qty":3000,"price":"$0.38077","currency":"USD"},{"qty":5000,"price":"$0.36764","currency":"USD"},{"qty":10000,"price":"$0.34926","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/aec32b0d4a5f742c03de5786d68c7607.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mated stacking height of DF40B-10DS-0.4V(58)?","answer":"The mated stacking height is 1.5mm.
