The mated stacking height is 1.5mm, which sets the gap between parallel PCBs in a compact assembly. At 0.40mm pitch, the footprint demands careful PCB routing — trace widths and via keepouts need to be planned for the tight pad spacing. This is a production-current part — active lifecycle, RoHS compliant, and available through the independent channel against an RFQ. ## What crosses to it when the original is dry? The closest functional peer is the DF40GL-44DP-0.4V(58), which shares the exact same 44-position count, 0.016\" (0.40mm) pitch, 1.5mm stacking height, gold plating, and shielded SMT construction. Mechanically and electrically they are identical, so a board laid out for one accepts the other without any footprint or clearance change. The mating receptacle is the DF40GL-44DS-0.4V(58), also a 44-position, 0.40mm pitch, gold-plated part with center strip contacts. That's the half you pair with this header to complete the board-to-board link.","metaTitle":"Hirose DF40GL-44DP-0.4V(51) 44-Pos 0.40mm Header, SMT","metaDescription":"Hirose DF40GL-44DP-0.4V(51) 44-position 0.016\" (0.40mm) pitch SMT header, gold contacts, shielded, 1.5mm stacking height.","metaKeywords":null},"attributes":{"series":"DF40GL","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":"DF40GL","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Shielded, 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":"0.045\\\" (1.14mm)","Base Product Number":"DF40G","Number of Positions":"44","Mated Stacking Heights":"1.5mm","Contact Finish Thickness":"1.97µin (0.050µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4500","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.45000","currency":"USD"},{"qty":10,"price":"$1.25800","currency":"USD"},{"qty":25,"price":"$1.20440","currency":"USD"},{"qty":50,"price":"$1.17760","currency":"USD"},{"qty":100,"price":"$1.12410","currency":"USD"},{"qty":250,"price":"$1.01708","currency":"USD"},{"qty":500,"price":"$0.93678","currency":"USD"},{"qty":1000,"price":"$0.80295","currency":"USD"},{"qty":2500,"price":"$0.74942","currency":"USD"},{"qty":5000,"price":"$0.71195","currency":"USD"},{"qty":10000,"price":"$0.69589","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c1e975d984bbbf30d2ff3078feec07e7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy DF40GL-44DP-0.4V(51) and how is it quoted?","answer":"Submit an RFQ for your BOM quantity."},{"question":"Will DF40GL-44DP-0.4V(51) drop into a board laid out for DF40GL-44DP-0.4V(58)?","answer":"Yes, they are mechanically and electrically identical — same 44 positions, 0.40mm pitch, 1.5mm stacking height, gold plating, and shielded SMT footprint.
