It's a surface-mount board-to-board interconnect designed for a 3.5mm mated stack height — the z-height budget that decides whether it clears the enclosure lid or the opposing board's tallest component. ## Sourcing this obsolete part — what crosses when it's dry This part is marked Obsolete on the official record. There is no listed direct replacement or cross-reference from JST within the evidence — no successor order code, no pin-compatible alternative named. ## Mating half and termination basics Termination is surface-mount only; the Tape & Reel packaging suits automated pick-and-place. The 0.50mm pitch means the PCB footprint needs tight registration — no hand-soldering this one. Gold on the contact finish gives good oxidation resistance for the signal path, but the mating cycle life is driven more by the shroud alignment than the plating alone.","metaTitle":"JST 40P3.5-JMCS-G-TF(N) Plug, 40 Pos, 0.50mm Pitch, Obsolete","metaDescription":"JST JMC series 40P3.5-JMCS-G-TF(N) plug with outer shroud contacts, 40 positions, 0.50mm pitch, 2 rows, SMT, gold finish, 3.5mm stacking height.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Board-to-Board Connectors"],"specifications":{"Mfr":"JST Sales America Inc.","Pitch":"0.020\\\" (0.50mm)","Series":"JMC","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Mounting Type":"Surface Mount","Connector Type":"Plug, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"-","Base Product Number":"40P3.5-J","Number of Positions":"40","Mated Stacking Heights":"3.5mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8c653c81397fb0c79388c30e672d0c7e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 40P3.5-JMCS-G-TF(N) available via RFQ confirmation?","answer":"No live stock is held; submit an RFQ for your quantity and we'll locate traceable date-coded inventory."},{"question":"Is 40P3.5-JMCS-G-TF(N) obsolete and what is the replacement?","answer":"Yes, the official lifecycle status is Obsolete.
