MR-J2S-20A-PQ108T021 Mitsubishi AC Servo Drive

MR-J2S-20A-PQ108T021 Mitsubishi AC servo drive

This listing is for maintenance buyers matching a Mitsubishi MR-J servo amplifier by exact part number. Use the full model code MR-J2S-20A-PQ108T021 when comparing the installed unit, machine documentation, motor nameplate, encoder connection, control mode, voltage class, connector set, and parameter backup requirements.

Condition options

• New: selected for buyers who need unused replacement hardware where available.
• Used in Great Condition: selected for repair, retrofit, and spare-part programs where a tested replacement is acceptable.

Compatibility checklist

• Confirm the complete MR-J2S-20A-PQ108T021 suffix, not only the MR-J2S-20A base family.
• Check servo motor and encoder compatibility before replacing an installed drive.
• Verify input power, control interface, alarm history, parameter backup, and connector condition.
• Have a qualified technician review setup before energizing the machine.

Regional sourcing support is written for buyers in North America, Europe, Australia, and the Middle East. Europe landed pricing can differ from the baseline USD price because of duties, VAT handling, and regional fulfillment assumptions.

FAQ

Can I replace this with another MR-J2S model? Do not assume interchangeability from the family name alone. Match the complete model, rating, control interface, and machine configuration.

Is MR-J2S interchangeable with MR-J3W? Treat them as different generations and configurations unless your engineering documentation explicitly approves the change.
