Product details

The Mitsubishi FX5U-32MT/ESS is the entry-level CPU in the MELSEC iQ-F family with 16 sink/source 24 V DC inputs and 16 transistor source outputs. The transistor outputs switch at higher rates than relay versions and hold up to frequent cycling without contact degradation.

Sourcing reality for this BOM line

The FX5U-32MT/ESS carries a current lifecycle stage, meaning no planned phase-out window. Standard lead times apply for new orders; the part is specified into the BOM and quoted against an RFQ. Mitsubishi has not published a successor for this order code, and given its active status, no cross-reference is needed for procurement planning. The 16-point I/O count makes it a common spare on a single-machine cell — keep one on the shelf if uptime risk is high.

Frequently asked questions

What is the closest functional alternative to FX5U-32MT/ESS?

The FX5U-32MR/ES is the same form factor with the same 16 inputs, but uses relay outputs instead of transistors. If your application can tolerate lower output switching frequency and needs isolated contacts, the MR variant is a direct alternative.

What are the key input/output specifications of FX5U-32MT/ESS?

It has 16 sink/source 24 V DC inputs and 16 transistor source outputs. Power supply is 100-240 V AC 50/60 Hz.

Will FX5U-32MT/ESS drop into a panel built for FX5U-32MR/ES without rewiring?

Mechanically and electrically, yes — same mounting footprint and same input wiring. However, the output side changes from relays to transistors, so check load current and switching frequency requirements before swapping. If the original design used relay outputs, the transistor version may need an external interposing relay for high-inrush or isolation-critical loads.
