Silver-plated copper alloy contacts terminate via solder to the board; the LCP housing includes a board guide for alignment during reflow. ## Series position: 3-conductor vs 5-contact variant Within the STX family, the STX-2500-3NTR (3 conductors, no internal switch) shares its 2.50 mm mating diameter and SMT right-angle footprint with the STX-2550-5NTR, which adds two internal switches and five contacts — the board layout and plug interface are common, but the switch contacts change the circuit function. The through-hole STX-2000-3N uses a PBT housing and bulk packaging, so the SMT reflow profile and tape-and-reel feed of the STX-2500-3NTR do not cross directly.","metaTitle":"Kycon STX-2500-3NTR 2.5mm Phone Jack, 3 Conductor, SMT","metaDescription":"Kycon STX-2500-3NTR female phone jack, 2.50mm industry recognized mating diameter, 3 conductors, SMT right-angle, silver-plated contacts, ROHS3 compliant","metaKeywords":null},"attributes":{"series":"STX-2500","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-2500","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Board Guide","Includes":"-","Shielding":"Unshielded","Body Color":"Black","Termination":"Solder","Thread Size":"-","Signal Lines":"Stereo (3 Conductor, TRS)","Body Material":"-","Cable Opening":"-","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Phone Jack","Product Status":"Active","Actual Diameter":"0.102\\\" (2.60mm)","Panel Hole Size":"-","Voltage - Rated":"-","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Housing Material":"Liquid Crystal Polymer (LCP)","Insulation Color":"-","Internal Switch(s)":"Does Not Contain Switch","Base Product Number":"STX","Mating Length/Depth":"-","Operating Temperature":"-25°C ~ 80°C","Contact Material - Plating":"Silver","Number of Positions/Contacts":"3 Conductors, 3 Contacts","Industry Recognized Mating Diameter":"2.50mm (0.094\\\", 3/32\\\", Sub Mini, Miniature) - Headphone"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.27000","currency":"USD"},{"qty":10,"price":"$1.07400","currency":"USD"},{"qty":25,"price":"$1.03000","currency":"USD"},{"qty":50,"price":"$1.00820","currency":"USD"},{"qty":100,"price":"$0.96430","currency":"USD"},{"qty":250,"price":"$0.87668","currency":"USD"},{"qty":500,"price":"$0.78902","currency":"USD"},{"qty":1000,"price":"$0.70134","currency":"USD"},{"qty":2000,"price":"$0.65751","currency":"USD"},{"qty":3000,"price":"$0.63559","currency":"USD"},{"qty":5000,"price":"$0.61368","currency":"USD"},{"qty":10000,"price":"$0.58299","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"How do I get current pricing and availability for STX-2500-3NTR?","answer":"The STX-2500-3NTR is available in Tape & Reel (TR) and Cut Tape (CT) packaging."},{"question":"Will STX-2500-3NTR drop into a panel that was specified around STX-2550-5NTR without rewiring?","answer":"The STX-2500-3NTR and STX-2550-5NTR share the same 2.50 mm mating diameter, SMT right-angle footprint, and board guide feature, so the PCB layout and plug interface are common.
