The 3-position SM03B-SRSS-TB shares the same 1.00 mm pitch, 1 A rating, and right-angle SMT footprint — just fewer circuits. The 6-position SM06B-SRSS-TB(LF)(SN) adds two more positions on the same pitch, so the board footprint scales linearly with position count. All three use the same mating receptacle and terminal family, so a harness built for one can cross to the others by swapping the header.","metaTitle":"SM04B-SRSS-TB(LF)(SN) JST SH/SR Header 4-Pos 1mm Pitch SMT","metaDescription":"JST SM04B-SRSS-TB(LF)(SN) SH/SR series header, 4 positions, 1.00mm pitch, SMT right-angle, shrouded 4-wall, tin-plated contacts, 1A/50V, UL94 V-0.","metaKeywords":null},"attributes":{"series":"SH/SR","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"JST Sales America Inc.","Style":"Board to Cable/Wire","Series":"SH/SR","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.039\\\" (1.00mm)","Product Status":"Active","Voltage Rating":"50V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.114\\\" (2.90mm)","Ingress Protection":"-","Base Product Number":"SM04B-SR","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A","Operating Temperature":"-25°C~85°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.57000","currency":"USD"},{"qty":10,"price":"$0.49300","currency":"USD"},{"qty":100,"price":"$0.40630","currency":"USD"},{"qty":500,"price":"$0.35328","currency":"USD"},{"qty":1000,"price":"$0.29146","currency":"USD"},{"qty":3000,"price":"$0.26496","currency":"USD"},{"qty":6000,"price":"$0.25613","currency":"USD"},{"qty":9000,"price":"$0.23847","currency":"USD"},{"qty":15000,"price":"$0.23493","currency":"USD"},{"qty":30000,"price":"$0.22963","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/01a3d0422a428094e98b60769fffa9d7.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/jst/SM04B-SRSS-TBLFSN","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/jst/SM04B-SRSS-TBLFSN when reusing this data.
