It mates with the matching FX23L series header (outer shroud contacts) to form a board-to-board mezzanine stack at a 5.80mm mated height. The hybrid contact set lets a single connector carry both low-current signal lines and a moderate power rail, reducing the connector count on densely populated mezzanine boards. Surface-mount termination and integrated board guide and pick-and-place features make this part suited for automated SMT assembly lines. The gold-plated contacts (4.00µin) provide a corrosion-resistant mating interface for moderate-cycle applications in controlled environments. The dual-row layout doubles the contact density at the board edge, but the fan-out on inner rows requires a via-in-pad or a short dog-leg trace to an inner layer. The 4 power contacts (positions 21–24) are typically assigned to a single voltage rail or a return path. Their current capacity is higher than the signal contacts due to wider contact beams, but the 0.50mm pitch still limits the total power per contact compared to a dedicated power connector. Plan the power trace width from the pad to the plane accordingly.","metaTitle":"Hirose FX23L-20S-0.5SV(20) Receptacle, 24 Pos, 0.50mm","metaDescription":"Hirose FunctionMax FX23L receptacle, 24 positions (20 signal + 4 power), 0.50mm pitch, 5.80mm board height, SMT, gold plating, RoHS.","metaKeywords":null},"attributes":{"series":"FunctionMax™ FX23L","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™ FX23L","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Board Guide, Pick and Place","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":"0.228\\\" (5.80mm)","Base Product Number":"FX23","Number of Positions":"24 (20 + 4 Power)","Mated Stacking Heights":"-","Contact Finish Thickness":"4.00µin (0.100µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3800","stockQuantity":21,"priceTiers":[{"qty":1,"price":"$3.38000","currency":"USD"},{"qty":10,"price":"$3.07200","currency":"USD"},{"qty":25,"price":"$2.91000","currency":"USD"},{"qty":50,"price":"$2.84220","currency":"USD"},{"qty":100,"price":"$2.70680","currency":"USD"},{"qty":250,"price":"$2.36844","currency":"USD"},{"qty":500,"price":"$2.30078","currency":"USD"},{"qty":1000,"price":"$1.96243","currency":"USD"},{"qty":1500,"price":"$1.89476","currency":"USD"},{"qty":2500,"price":"$1.82709","currency":"USD"},{"qty":5000,"price":"$1.75942","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy FX23L-20S-0.5SV(20)?","answer":"Submit a request for quote to confirm current availability and pricing."},{"question":"What is the pitch of FX23L-20S-0.5SV(20)?","answer":"The pitch is 0.020\" (0.50mm)."},{"question":"How many positions does FX23L-20S-0.5SV(20) have?","answer":"It has 24 positions total — 20 signal contacts and 4 power contacts, arranged in two rows."},{"question":"What is the height above board for FX23L-20S-0.5SV(20)?","answer":"The height above board is 0.228\" (5.80mm)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/FX23L-20S-0.5SV~120~2","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/FX23L-20S-0.5SV~120~2 when reusing this data.
