Product details

What This 4-Pin FFC Connector Does for Your Board

The JST 04FMN-BMT-A-TF(LF)(SN) is a vertical SMD FFC connector from the FMN series, offering 4 positions at 1.00 mm pitch. It accepts 0.30 mm thick FFC cable and terminates via solder to the PCB. The Low Insertion Force (LIF) design reduces pad wear during assembly and rework — a practical benefit when the flex circuit sees multiple insertions over the product life.

The housing is black polyamide (PA6T) with UL94 V-0 flammability rating, suitable for equipment requiring flame-retardant materials inside the enclosure. Phosphor bronze contacts with tin plating provide reliable electrical connection for low-cycle duty.

No pin-compatible direct replacement is listed by JST — this is the active order code for the 4-position, 1.00 mm pitch, vertical SMD FMN connector.

Frequently asked questions

Is the 04FMN-BMT-A-TF(LF)(SN) RoHS compliant?

Yes, the (LF)(SN) suffix indicates RoHS compliance and tin-plated contacts.

Does the 04FMN-BMT-A-TF(LF)(SN) have a locking feature?

No locking latch is specified. The Low Insertion Force (LIF) design relies on friction retention — adequate for applications without vibration or cable strain. For environments with movement, consider a connector with a positive lock.

What is the closest pin-compatible alternative to 04FMN-BMT-A-TF(LF)(SN) in this FFC / FPC Cable Assemblies family?

No direct pin-compatible replacement is listed by JST for this specific 4-position, 1.00 mm pitch, vertical SMD, tin-plated configuration. The 04FMN-BMT-A-TF(LF)(SN) is the active order code — confirm your BOM position count and mating half before substituting.
