This part is marked Obsolete. The 0.020\" (0.50mm) pitch is tight — the board footprint must match the contact pattern exactly, and trace escape from the inner rows of a 50-position, dual-row layout requires either via-in-pad or fine-line routing. The 0.130\" (3.30mm) height above board gives a low-profile mezzanine stack, but the mating header's height also sets the final gap. Gold contacts handle the insertion cycles typical of a production board or field-service disconnect without fretting corrosion.","metaTitle":"JST 50RF-JMCS-G-1B-TF(N)(LF)(SN) Receptacle, 50 Pos","metaDescription":"JST JMC series 50-position receptacle, 0.020\" (0.50mm) pitch, dual-row, gold contacts, SMT.","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":"Board Guide, Solder Retention","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"0.130\\\" (3.30mm)","Base Product Number":"50RF-JMC","Number of Positions":"50","Mated Stacking Heights":"-","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0412","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8c653c81397fb0c79388c30e672d0c7e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the JST 50RF-JMCS-G-1B-TF(N)(LF)(SN)?","answer":"No stock-holding claim is made."},{"question":"Is 50RF-JMCS-G-1B-TF obsolete?","answer":"Yes, JST has marked the 50RF-JMCS-G-1B-TF(N)(LF)(SN) as Obsolete.
