It uses a 2-row configuration and is designed for surface-mount soldering, with a mated stacking height of 0.98 mm and a height above board of 0.75 mm. The gold-plated contacts with 2.00 µin (0.051 µm) thickness suit repeated mating cycles in signal-level applications. This connector is typically used in compact portable electronics, handheld devices, and other space-constrained assemblies where a low-profile, high-density board-to-board interconnect is required. ## Key Specs for the Build The 40 positions match a 40-circuit signal BOM line. The 0.75 mm height above board and 0.98 mm mated stack height define the z-axis clearance in the enclosure. The 40-position DF37C-40DP-0.4V(51) sits alongside the 50-position DF37C-50DP-0.4V(51) in the same DF37 series. Both share the 0.40 mm pitch, 2-row layout, gold plating, and 0.75 mm height. ## Mating Connector The mated pair achieves a stacking height of 0.98 mm. Confirm the receptacle order code matches the 40-position, 0.40 mm pitch requirement.","metaTitle":"Hirose DF37C-40DP-0.4V(51) 40-Position 0.40mm Pitch Header","metaDescription":"Hirose DF37C-40DP-0.4V(51) 40-position 0.40mm pitch header, outer shroud contacts, gold plating, 0.75mm height, RoHS compliant, active production, sourced to","metaKeywords":null},"attributes":{"series":"DF37","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":"DF37","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","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":"0.030\\\" (0.75mm)","Base Product Number":"DF37C","Number of Positions":"40","Mated Stacking Heights":"0.98mm","Contact Finish Thickness":"2.00µin (0.051µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.64000","currency":"USD"},{"qty":10,"price":"$1.42400","currency":"USD"},{"qty":25,"price":"$1.36360","currency":"USD"},{"qty":50,"price":"$1.33320","currency":"USD"},{"qty":100,"price":"$1.27260","currency":"USD"},{"qty":250,"price":"$1.15140","currency":"USD"},{"qty":500,"price":"$1.06050","currency":"USD"},{"qty":1000,"price":"$0.90900","currency":"USD"},{"qty":2500,"price":"$0.84840","currency":"USD"},{"qty":8000,"price":"$0.78780","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/3aa4291611ad64fcbe6042571475da76.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DF37C-40DP-0.4V(51) RoHS compliant?","answer":"Yes, the DF37C-40DP-0.4V(51) is RoHS Compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/DF37C-40DP-0.4V~151~2","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/DF37C-40DP-0.4V~151~2 when reusing this data.
