Compatible Replacement & Equivalent Models
If the MR-MG30 is discontinued or unavailable, the following models may serve as functional equivalents depending on your servo amplifier series and regenerative capacity requirements:
- Mitsubishi MR-RB30 – Direct regenerative resistor replacement for MR-J4/MR-J3 series; 30 W rated
- Mitsubishi MR-RB50 – Higher capacity (50 W) option for systems with greater regenerative load
- Mitsubishi MR-RB032 – Compact regenerative option for MR-J2S series amplifiers
- Mitsubishi MR-MG10 – Lower capacity (10 W) variant in the same MR-MG series
- Third-party equivalents – Must match resistance value (Ω), wattage, and connector type; consult Konmask engineering team for verification
⚠ Always verify electrical compatibility (resistance, wattage, voltage rating) before substituting. Contact us for a free compatibility check.
Why Choose the Original MR-MG30
- ✅ Factory-certified for Mitsubishi MELSERVO amplifier series
- ✅ Guaranteed thermal and electrical compatibility
- ✅ Plug-and-play installation — no parameter reconfiguration required

- ✅ Traceable part numbers (0100-20012 / 800075V0001) for MRO and audit compliance
Typical Applications
- CNC machine tool servo axes (milling, turning, grinding)
- Robotic arm joint drives requiring regenerative braking
- Packaging and labeling line servo systems
- Semiconductor and electronics assembly equipment
- Conveyor and material handling automation
- Injection molding machine servo retrofit projects
System Compatibility
The MR-MG30 regenerative unit is compatible with the following Mitsubishi servo amplifier families:
- MR-J2 / MR-J2S series
- MR-J3 series (verify connector pinout)
- MR-J4 series (verify connector pinout)
- MR-C series (legacy systems)
For MR-J5 series or newer platforms, consult the latest Mitsubishi MELSERVO catalog or contact Konmask for updated compatibility data.
Selection Guide
Use the following criteria to confirm the MR-MG30 is the right choice for your application:
- Step 1 – Identify your servo amplifier model (e.g., MR-J2S-40A, MR-J3-70A)
- Step 2 – Calculate regenerative energy — refer to Mitsubishi’s regenerative option selection tool in the servo amplifier manual
- Step 3 – Match rated wattage — MR-MG30 = 30 W; upgrade to MR-RB50 if load exceeds 30 W
- Step 4 – Verify connector and mounting — confirm physical fit with your control cabinet layout
- Step 5 – Check part number cross-reference — 0100-20012 and 800075V0001 are both valid identifiers for this unit

Replacement & Compatibility FAQ
Q: Can the MR-MG30 replace the MR-RB30?
A: They serve similar functions but are different product lines. MR-RB30 is the current catalog replacement for many MR-J3/J4 applications. Verify your amplifier’s manual before substituting.
Q: What do part numbers 0100-20012 and 800075V0001 refer to?
A: Both are valid Mitsubishi internal part numbers for the MR-MG30 unit — used interchangeably in procurement and MRO systems.
Q: Is the MR-MG30 still in production?
A: This model may be discontinued or in limited supply. Konmask maintains surplus stock and can source equivalents. Contact us for current availability.
Q: Can I use a generic resistor as a replacement?
A: Not recommended. Generic resistors lack the thermal protection and connector integration of OEM units, risking amplifier damage. Use certified equivalents only.
Q: Do you provide a warranty?
A: Yes — all units carry a minimum 90-day functional warranty. Extended warranty available on request.
