Use anything thicker and the IDC slot won't close; anything thinner and the insulation won't pierce reliably. The closed-end housing blocks wire push-through, so the conductor stops where it should — a detail that matters when you're building a harness without a backshell. ## Still in production — no last-time-buy scramble It's ROHS3 compliant, which covers the current EU directive.","metaTitle":"JST 12SR-3S SR Series Receptacle, 12 Pos, 1.00mm Pitch, IDC","metaDescription":"JST 12SR-3S SR series receptacle, 12 positions, 1.00mm pitch, IDC termination for 30 AWG wire, tin contacts, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"SR","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"JST Sales America Inc.","Color":"Natural","Pitch":"0.039\\\" (1.00mm)","Series":"SR","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete","Wire Gauge":"30 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Contact Finish":"Tin","Fastening Type":"-","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"12SR","Number of Positions":"12","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9100","priceTiers":[{"qty":1,"price":"$0.91000","currency":"USD"},{"qty":10,"price":"$0.76900","currency":"USD"},{"qty":25,"price":"$0.73720","currency":"USD"},{"qty":50,"price":"$0.72160","currency":"USD"},{"qty":100,"price":"$0.69030","currency":"USD"},{"qty":250,"price":"$0.62752","currency":"USD"},{"qty":500,"price":"$0.56476","currency":"USD"},{"qty":1000,"price":"$0.50201","currency":"USD"},{"qty":2500,"price":"$0.45495","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b6b85058330abf039f5e059a7f9f37e1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/12SR-3S/alternatives.json"},"ai":{"faq":[{"question":"What is the pin pitch of JST 12SR-3S?","answer":"The pin pitch is 0.039\" (1.00 mm).
