The 0.40mm pitch and 2.5mm mated stacking height let you route high-density signals between parallel PCBs in compact handheld devices, wearables, or camera modules. ## Stack Height and Board Spacing The mated stacking height is 2.5mm, fixing the gap between the two PCBs once the header and receptacle are mated. ## SMT Termination and Assembly Features Surface-mount termination with solder retention pads and a pick-and-place vacuum area — the connector is designed for automated assembly. The solder retention feature holds the part in place during reflow, preventing tombstoning or shift on a fine-pitch 0.40mm footprint. ## Position Count and Series Siblings At 50 positions, this is a high-density member of the DF40T family. The sibling DF40TC(3.0)-40DS-0.4V(58) shares the same 0.40mm pitch and gold plating but drops to 40 positions and a taller 2.90mm stack height — choose it when the board spacing opens up and you need fewer lines. The DF40TC-50DS-0.4V(58) and DF40TC-50DS-0.4V(51) also carry 50 positions at the same pitch but with a 1.45mm stack height, which is nearly half the z-height of this part — those are for ultra-thin builds where the 2.5mm gap won't fit.","metaTitle":"Hirose DF40TC(2.5)-50DS-0.4V(58) Receptacle, 50 Pos","metaDescription":"Hirose DF40TC(2.5)-50DS-0.4V(58) receptacle, center strip contacts, 50 positions, 0.40mm pitch, 2.5mm stacking height, gold plating.","metaKeywords":null},"attributes":{"series":"DF40T","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":"DF40T","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Pick and Place, 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":"0.094\\\" (2.40mm)","Number of Positions":"50","Mated Stacking Heights":"2.5mm","Contact Finish Thickness":"1.97µin (0.050µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.18000","currency":"USD"},{"qty":10,"price":"$1.89900","currency":"USD"},{"qty":25,"price":"$1.81800","currency":"USD"},{"qty":50,"price":"$1.77760","currency":"USD"},{"qty":100,"price":"$1.69680","currency":"USD"},{"qty":250,"price":"$1.53520","currency":"USD"},{"qty":500,"price":"$1.41400","currency":"USD"},{"qty":1000,"price":"$1.18924","currency":"USD"},{"qty":2000,"price":"$1.14961","currency":"USD"},{"qty":3000,"price":"$1.10996","currency":"USD"},{"qty":5000,"price":"$1.05446","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ee353916a52fdc0d2aa13cbbf97c384a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mated stacking height of DF40TC(2.5)-50DS-0.4V(58)?","answer":"The mated stacking height is 2.5mm — that is the total gap between the two PCBs when the receptacle and its matching header are fully mated."},{"question":"What is the pin pitch of DF40TC(2.5)-50DS-0.4V(58)?","answer":"The pitch is 0.016\" (0.40mm) — a fine-pitch connector requiring a matching PCB footprint and careful routing for signal integrity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/DF40TC~12.5~2-50DS-0.4V~158~2","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/DF40TC~12.5~2-50DS-0.4V~158~2 when reusing this data.
