Is the Mitsubishi Electric MR-J3-200BS4 discontinued?

On ECS's lifecycle assessment, the MR-J3-200BS4 is discontinued and no longer supplied by Mitsubishi Electric.

Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.

What Total Discontinuation means for you

The manufacturer has finished with the part. You may still find one through surplus or refurbished sellers, or in another site's stores, but that is not a supply chain. When a unit fails, your options are to find one and restore the program onto it, or to migrate the machine.

Both routes start in the same place: having the program. Without a backup, a found spare is just hardware.

How ECS defines Total Discontinuation · all four lifecycle stages

Before replacing servo or motion hardware

Motion hardware is usually tied to the motor, feedback device, gearing, tuning, safety functions and controller-side motion instructions. We would identify those dependencies before assuming a newer unit can replace the existing one.

For a production-critical axis, planned migration gives time to retune and prove motion safely; doing that work during an unplanned stoppage is where obsolescence becomes expensive.

Common questions about the MR-J3-200BS4

Is the Mitsubishi Electric MR-J3-200BS4 discontinued?

On ECS's lifecycle assessment, the MR-J3-200BS4 is discontinued and no longer supplied by Mitsubishi Electric.

Can I still buy a MR-J3-200BS4?

Not from Mitsubishi Electric. Surplus and refurbished sellers may have stock; check provenance and test before fitting.

How do I back up a MR-J3-200BS4?

It is programmed with MR Configurator2. The exact software version and cable depend on the unit's firmware. ECS records both for every unit it captures, alongside a verified backup.

With a backup, a failed unit is hours. Without one, it is days.

A Capture audit finds every MR-J3-200BS4 on your site, takes a backup of each one it can reach, and records the software version and cable needed to restore it. When a discontinued unit fails and a replacement turns up, the program is ready to load.

  • Every device located, photographed and lifecycle-checked
  • Backups taken on the day, with software version and cable recorded
  • Findings report, plus a populated Command Centre
  • No production downtime
