It's a right-angle surface-mount plug with outer shroud contacts, meaning it mates with a JMC receptacle that carries inner contacts. Gold plating on the contacts suits it for signal-level interconnect where moderate mating cycle life matters, not power duty. This part is officially obsolete. No successor order code is listed on record, so there's no direct drop-in from JST. No official cross-reference to a JST 20PS-JMCS-G-1C or any other specific replacement is on record. This is the plug with outer shroud contacts, so it mates with a JMC series receptacle that has inner contacts — same 0.50mm pitch, same 20 positions. No crimp terminals here — this is a direct-solder interface, so the board footprint and stencil design for the 0.50mm pitch pads are what determine joint reliability.","metaTitle":"JST 20PS-JMCS-G-1B-TF(N)(LF)(SN) 20 Position 0.50mm Plug","metaDescription":"JST JMC series 20PS-JMCS-G-1B-TF(N)(LF)(SN) 20-position 0.50mm pitch right-angle SMT plug with gold contacts.","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)","Features":"Board Guide, Solder Retention","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Plug, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"0.170\\\" (4.33mm)","Base Product Number":"20PS-JMCS","Number of Positions":"20","Mated Stacking Heights":"-","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8c653c81397fb0c79388c30e672d0c7e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for 20PS-JMCS-G-1B-TF(N)(LF)(SN)?","answer":"For an existing design, source through independent distribution.
