The connector is surface-mount, with gold-plated contacts (4.00µin thickness) that handle the moderate mating cycle count typical of a production board stack. A built-in ground plate runs through the connector body to manage return current and reduce EMI between the stacked boards. The 0.50mm pitch packs 80 signal contacts into a footprint roughly 20mm long — that is 40 contacts per row. Routing that density on a standard two-layer board is tight; you will likely need four or more layers to fan out the traces between vias. The 5mm mated stack height is the dimension to design for: the receptacle's own height plus the header's 4.50mm above-board profile add up to the 5mm post-mate gap, so your mezzanine board spacing is fixed at 5mm. The ground plate gives you a low-inductance return path right at the connector, which helps keep signal integrity clean on high-speed lines without relying solely on board-layer stitching.","metaTitle":"FX10A-80P/8-SV1(91) Hirose FunctionMax™ FX10 Header, 80 Pos","metaDescription":"Hirose FX10A-80P/8-SV1(91) FunctionMax™ FX10 header, 80 positions, 0.020\" (0.50mm) pitch, 5mm stacking height, SMT, gold contacts, RoHS.","metaKeywords":null},"attributes":{"series":"FunctionMax™ FX10","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Pitch":"0.020\\\" (0.50mm)","Series":"FunctionMax™ FX10","Package":"Tape & Reel (TR)","Features":"Board Guide, Ground Plate, 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":"0.177\\\" (4.50mm)","Base Product Number":"FX10","Number of Positions":"80","Mated Stacking Heights":"5mm","Contact Finish Thickness":"4.00µin (0.100µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3976","stockQuantity":0,"priceTiers":[{"qty":1000,"price":"$3.39764","currency":"USD"},{"qty":2000,"price":"$3.28048","currency":"USD"},{"qty":3000,"price":"$3.16332","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dd341c0f6d8db12322424d9acdd6dcc2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the FX10A-80P/8-SV1(91) and how is it quoted?","answer":"Submit a request with your target quantity and the current availability and pricing will be confirmed at quote time."},{"question":"What is the stacking height for the FX10A-80P/8-SV1(91)?","answer":"The FX10A-80P/8-SV1(91) supports a mated stacking height of 5mm, which sets the spacing between the two parallel PCBs once mated with the matching receptacle."},{"question":"Is the FX10A-80P/8-SV1(91) RoHS compliant?","answer":"Yes, the FX10A-80P/8-SV1(91) is RoHS compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/FX10A-80P-8-SV1~191~2","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/FX10A-80P-8-SV1~191~2 when reusing this data.
