FMN series, 04FMN-BMTTN-A-TF, FFC connector, 4 positions, 0.039\" (1.00mm) pitch, vertical SMD, tin-plated phosphor bronze contacts, rated 0.5A, 50V, Low Insertion Force (LIF), UL94 V-0 housing.","salesMarkdown":"## What this 4-position FFC connector does The 04FMN-BMTTN-A-TF is a 4-position, 0.039\" (1.00mm) pitch FFC connector from JST's FMN series, terminated by solder to a surface-mount pad and mated vertically to a 0.30mm-thick FFC cable. Rated 0.5A per contact at 50V, it handles low-power signal or control lines in tight board-to-flex applications. The Low Insertion Force (LIF) design reduces wear on the FFC pads during repeated mating cycles, a practical advantage in field-service scenarios where the cable is swapped more than once. ## Board-fit and routing details A vertical SMD orientation with a 5.10mm height above board leaves a low profile for clearance under adjacent components or enclosure lids. The housing is black polyamide (PA6T) rated UL94 V-0, and the contacts are tin-plated phosphor bronze — adequate for moderate environments but not for high-vibration or corrosive atmospheres where gold plating would be preferred. Note: This part is listed as RoHS non-compliant, which may affect compliance documentation for certain markets. ## How it compares to nearby siblings Compared to the 04FMN-BMT-A-TF(LF)(SN), the 04FMN-BMTTN-A-TF shares the same pitch, height, current rating, and contact finish — the difference is in the packaging suffix and RoHS compliance status. The 04FMN-SMT-A-TF is a right-angle SMD variant with a lower 3.00mm stack height, useful when the FFC must exit parallel to the board rather than vertically. If you need one more circuit, the 05FMN-BMTTN-A-TF offers the same footprint and ratings with 5 positions.","metaTitle":"04FMN-BMTTN-A-TF JST FMN 4-Pin 1mm Pitch FFC Connector","metaDescription":"JST Sales America Inc. 04FMN-BMTTN-A-TF FMN series FFC connector, 4 positions, 1.00mm pitch, vertical SMD, 0.5A, 50V, LIF, UL94 V-0.","metaKeywords":null},"attributes":{"series":"FMN","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["FFC / FPC & Ribbon Connectors","FFC / FPC Cable Assemblies"],"specifications":{"Mfr":"JST Sales America Inc.","Pitch":"0.039\\\" (1.00mm)","Series":"FMN","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Low Insertion Force (LIF)","Termination":"Solder","Housing Color":"Black","Mating Cycles":"-","Mounting Type":"Surface Mount","Actuator Color":"-","Cable End Type":"Straight","Contact Finish":"Tin","Flat Flex Type":"FFC","Product Status":"Active","Voltage Rating":"50V","Locking Feature":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polyamide (PA6T), Nylon 6T","Actuator Material":"-","FFC, FCB Thickness":"0.30mm","Height Above Board":"0.201\\\" (5.10mm)","Base Product Number":"04FMN-BM","Number of Positions":"4","Current Rating (Amps)":"0.5A","Operating Temperature":"-25°C ~ 85°C","Connector/Contact Type":"Contacts, Vertical - 1 Sided","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.46000","currency":"USD"},{"qty":10,"price":"$0.40000","currency":"USD"},{"qty":25,"price":"$0.36560","currency":"USD"},{"qty":50,"price":"$0.34420","currency":"USD"},{"qty":100,"price":"$0.32990","currency":"USD"},{"qty":250,"price":"$0.30124","currency":"USD"},{"qty":500,"price":"$0.28690","currency":"USD"},{"qty":1000,"price":"$0.23669","currency":"USD"},{"qty":2000,"price":"$0.22952","currency":"USD"},{"qty":3000,"price":"$0.21518","currency":"USD"},{"qty":5000,"price":"$0.20800","currency":"USD"},{"qty":10000,"price":"$0.19366","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/cfd1a574b2ad98ca05e1349a35aa3862.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will 04FMN-BMTTN-A-TF drop into a panel that was specified around 04FMN-BMT-A-TF(LF)(SN) without rewiring?","answer":"Yes — the 04FMN-BMTTN-A-TF shares the same 1.00mm pitch, 4-position count, vertical SMD orientation, and 5.10mm height as the 04FMN-BMT-A-TF(LF)(SN), so it is a direct mechanical and electrical fit.
