At a 0.020\" (0.50mm) pitch across two rows, it packs 144 signal positions into a board footprint that leaves room for escape routing on inner layers — the tight pitch means each signal pair needs a via-in-pad or a microvia stack to route out cleanly. This is a center-strip contact receptacle, meaning the mating interface is a row of contacts along the centerline of the connector body, designed to mate with the FX10 header's outer-shroud contacts. The connector is specified for mated stacking heights of 4mm and 5mm, which sets the board-to-board spacing in the enclosure. The 0.126\" (3.20mm) height above board of the receptacle alone means the header height must be chosen to hit the target stack — the FX10A-144P-SV(71) header at 0.138\" (3.50mm) height above board, for example, would exceed the 5mm stack if used here, so pair this receptacle with the correct header height for your z-height budget. ## Mating and Stack Height Compatibility This receptacle mates with the FX10 series header, specifically the outer-shroud contact header such as the FX10A-144P-SV(71) for a 144-position match. The mated stacking heights are 4mm or 5mm — the actual stack depends on the header height above board selected. The receptacle's board guide aligns with the header's guide posts during assembly, taking shear off the signal pins.","metaTitle":"Hirose FX10A-144S-SV, 144-pos 0.50mm pitch Receptacle","metaDescription":"Hirose FunctionMax FX10A-144S-SV receptacle, 144 positions, 0.020\" (0.50mm) pitch, SMT, gold contacts.","metaKeywords":null},"attributes":{"series":"FunctionMax™ FX10","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"Tray","Features":"Board Guide, 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":"0.126\\\" (3.20mm)","Base Product Number":"FX10","Number of Positions":"144","Mated Stacking Heights":"4mm, 5mm","Contact Finish Thickness":"4.00µin (0.100µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1900","priceTiers":[{"qty":1,"price":"$6.19000","currency":"USD"},{"qty":10,"price":"$5.61700","currency":"USD"},{"qty":25,"price":"$5.32000","currency":"USD"},{"qty":60,"price":"$5.19650","currency":"USD"},{"qty":120,"price":"$4.94900","currency":"USD"},{"qty":240,"price":"$4.33038","currency":"USD"},{"qty":480,"price":"$4.20665","currency":"USD"},{"qty":960,"price":"$3.58802","currency":"USD"},{"qty":2400,"price":"$3.34058","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dd341c0f6d8db12322424d9acdd6dcc2.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/FX10A-144S-SV/alternatives.json"},"ai":{"faq":[{"question":"What are the mating stacking heights for FX10A-144S-SV?","answer":"The FX10A-144S-SV is rated for mated stacking heights of 4mm and 5mm when paired with the correct FX10 series header.
