When mated with the corresponding Free Height plug, the assembly achieves a stack height of 8 mm, 9 mm, or 10 mm — the exact height depends on the plug variant selected. ## Gold Plating and Contact Reliability The outer shroud contacts provide mechanical alignment before the signal pins engage, reducing the risk of stubbing or bending during blind mating.","metaTitle":"TE Connectivity 5120521-1 Free Height Receptacle, 64 Pos","metaDescription":"TE Connectivity 5120521-1 Free Height (FH) IEEE 1386, PMC receptacle. 64 positions, 1.00 mm pitch, 30.0 µ\" gold contacts, SMT, 5.38 mm board height.","metaKeywords":null},"attributes":{"series":"Free Height (FH) IEEE 1386, PMC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Pitch":"0.039\\\" (1.00mm)","Series":"Free Height (FH) IEEE 1386, PMC","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Board Guide","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Height Above Board":"0.212\\\" (5.38mm)","Base Product Number":"5120521","Number of Positions":"64","Mated Stacking Heights":"8mm, 9mm, 10mm","Contact Finish Thickness":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5135","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.81000","currency":"USD"},{"qty":1,"price":"$6.19000","currency":"USD"},{"qty":10,"price":"$6.16000","currency":"USD"},{"qty":10,"price":"$5.42200","currency":"USD"},{"qty":25,"price":"$5.81920","currency":"USD"},{"qty":25,"price":"$5.28000","currency":"USD"},{"qty":50,"price":"$5.16640","currency":"USD"},{"qty":50,"price":"$5.67740","currency":"USD"},{"qty":100,"price":"$4.85420","currency":"USD"},{"qty":100,"price":"$5.39350","currency":"USD"},{"qty":250,"price":"$4.82580","currency":"USD"},{"qty":250,"price":"$4.82580","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the height above board for the 5120521-1?","answer":"The board height is 0.212\" (5.38mm), and when mated with the corresponding plug it supports stack heights of 8 mm, 9 mm, or 10 mm."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5120521-1","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/5120521-1 when reusing this data.
