It mounts through-hole right-angle, terminates by solder, and carries tin-plated brass and phosphor bronze contacts with a PBT housing rated -25°C to 85°C. ## Same-series sibling: switch vs no-switch The STX-3150-3N-1 and the STX-3150-3C-1 share the same 3-conductor, 3-contact layout, 3.50mm mating diameter, thread lock, and through-hole right-angle mounting — the difference is internal switching: the 3N-1 has no switch, while the 3C-1 carries two switches. The STX-3150-5C-1 adds two more contacts (5 total) and two switches, but keeps the same 3.50mm plug interface and thread lock.","metaTitle":"Kycon STX-3150-3N-1 Phone Jack, 3.50mm, Female","metaDescription":"Kycon STX-3150-3N-1 phone jack: 3 conductors, 3 contacts, 3.50mm industry mating diameter, female, through-hole right-angle, tin-plated contacts, thread lock","metaKeywords":null},"attributes":{"series":"STX-3150","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors","Audio Connectors"],"specifications":{"Mfr":"Kycon, Inc.","Gender":"Female","Series":"STX-3150","Package":"Bag","Features":"Thread Lock","Includes":"-","Shielding":"Unshielded","Body Color":"Black","Termination":"Solder","Thread Size":"-","Signal Lines":"Stereo (3 Conductor, TRS)","Body Material":"-","Cable Opening":"-","Mounting Type":"Through Hole, Right Angle","Connector Type":"Phone Jack","Product Status":"Active","Actual Diameter":"0.142\\\" (3.60mm)","Panel Hole Size":"-","Voltage - Rated":"-","lifecycle_stage":"unknown","Contact Material":"Brass, Phosphor Bronze","Housing Material":"Polybutylene Terephthalate (PBT)","Insulation Color":"Black","Internal Switch(s)":"Does Not Contain Switch","Mating Length/Depth":"-","Operating Temperature":"-25°C ~ 85°C","Contact Material - Plating":"Tin","Number of Positions/Contacts":"3 Conductors, 3 Contacts","Industry Recognized Mating Diameter":"3.50mm (0.141\\\", 1/8\\\", Mini Plug) - Headphone"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0500","priceTiers":[{"qty":1,"price":"$2.05000","currency":"USD"},{"qty":10,"price":"$1.78200","currency":"USD"},{"qty":25,"price":"$1.70680","currency":"USD"},{"qty":50,"price":"$1.66880","currency":"USD"},{"qty":100,"price":"$1.59290","currency":"USD"},{"qty":250,"price":"$1.44116","currency":"USD"},{"qty":500,"price":"$1.32740","currency":"USD"},{"qty":1000,"price":"$1.13776","currency":"USD"},{"qty":2500,"price":"$1.06191","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/3922d4176f747eb54f88207bddd8592a.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/STX-3150-3N-1/alternatives.json"},"ai":{"faq":[{"question":"What is the industry mating diameter for the STX-3150-3N-1?","answer":"The industry recognized mating diameter is 3.50mm (0.141\", 1/8\", mini plug) — a standard headphone jack size."},{"question":"Does the STX-3150-3N-1 include an internal switch?","answer":"No — the 3N-1 variant does not contain an internal switch, unlike the STX-3150-3C-1 which has two switches."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/kycon-inc/STX-3150-3N-1","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/kycon-inc/STX-3150-3N-1 when reusing this data.
