That flexibility means one board layout can serve two enclosure z-height budgets — useful when a single PCB design ships into different chassis. The ground plate running the length of the connector provides a low-inductance return path and a shield against radiated emissions, which matters when 220 high-speed lines share a narrow pitch and crosstalk becomes the limiting factor on signal integrity. ## Mating Half and Stack Height Math This receptacle mates with the Free Height (FH) plug 3-6318491-6, which carries outer shroud contacts and a board height of 7.45 mm. If your board stack calls for 5 mm, pair this receptacle with the shorter plug variant; for 8 mm, use the taller plug. The 0.50 mm pitch means the breakout fanout needs micro-vias or tight trace/space rules — plan the escape routing before committing the footprint.","metaTitle":"TE Free Height (FH) 3-6318490-6, 0.50mm Pitch, 220 Pos","metaDescription":"TE 3-6318490-6 Free Height (FH) receptacle, 220 positions, 0.50mm pitch, dual stacking heights of 5mm and 8mm.","metaKeywords":null},"attributes":{"series":"Free Height (FH)","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Pitch":"0.020\\\" (0.50mm)","Series":"Free Height (FH)","Package":"Tray","Features":"Board Guide, Ground Plate","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":"0.128\\\" (3.25mm)","Base Product Number":"6318490","Number of Positions":"220","Mated Stacking Heights":"5mm, 8mm","Contact Finish Thickness":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.4700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.47000","currency":"USD"},{"qty":10,"price":"$13.19200","currency":"USD"},{"qty":30,"price":"$12.84167","currency":"USD"},{"qty":60,"price":"$12.21000","currency":"USD"},{"qty":240,"price":"$11.01713","currency":"USD"},{"qty":450,"price":"$10.94696","currency":"USD"},{"qty":960,"price":"$9.54350","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the exact mated stacking height for 3-6318490-6?","answer":"The 3-6318490-6 supports two mated stacking heights: 5 mm and 8 mm, depending on the plug height paired with it."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/3-6318490-6","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/te-connectivity-amp-connectors/3-6318490-6 when reusing this data.
