Compatible Replacement & Equivalent Models
When the G1HCPU is discontinued or unavailable, the following models may serve as functional replacements depending on your system configuration. Always verify firmware, I/O mapping, and program compatibility before substitution.
- Mitsubishi Q02HCPU – MELSEC-Q Series high-performance CPU; requires base unit migration
- Mitsubishi Q06HCPU – Larger program capacity; suitable for expanded applications
- Mitsubishi Q12HCPU – Extended memory CPU for complex ladder/structured programs
- Mitsubishi Q25HCPU – High-end replacement with maximum I/O and network support
- Mitsubishi A2SHCPU – MELSEC-A Series equivalent for legacy system continuity
Note: Cross-series replacements require hardware reconfiguration and GX Works re-programming. Contact Konmask for migration support.

System Compatibility
| Component | Compatible |
|---|---|
| MELSEC-G Base Units | ✅ Yes |
| MELSEC-G I/O Modules | ✅ Yes |
| MELSEC-G Power Supply Modules | ✅ Yes |
| GX Developer Programming Software | ✅ Yes |
| GX Works2 / GX Works3 | ⚠️ Verify version compatibility |
| MELSEC-Q Series Base Units | ❌ Not compatible (different form factor) |
Selection Guide
Use the following criteria to confirm the G1HCPU is the right module for your application:
- Step 1 – Confirm Series: Verify your base unit is MELSEC-G Series (G-series backplane).
- Step 2 – Check Program Size: G1HCPU (H-type) supports high-capacity programs. If your application requires <8K steps, consider the G1CPU standard variant.
- Step 3 – Verify I/O Count: Confirm total I/O points fit within G-Series expansion limits.
- Step 4 – Network Requirements: If CC-Link or MELSECNET is required, confirm compatible network modules are available for G-Series.
- Step 5 – Software Toolchain: Ensure GX Developer or compatible IDE is available for programming and maintenance.

Replacement & Compatibility FAQ
Q: Can the G1HCPU be replaced by a Q-Series CPU directly?
A: No. MELSEC-Q and MELSEC-G use different base unit form factors. A full base unit replacement is required for cross-series migration.
Q: Is the G1HCPU still in production?
A: The MELSEC-G series is a legacy platform. Konmask maintains stock of genuine and refurbished units. Contact us for current availability.
Q: What programming software is required?
A: GX Developer is the primary tool for MELSEC-G CPU programming. GX Works2 may support import functions — verify with Mitsubishi documentation.
Q: Does Konmask offer a warranty?
A: Yes. All units come with a standard 90-day functional warranty. Extended warranty options are available — inquire at time of order.
Q: Can I get a test report or inspection certificate?
A: Yes. Inspection reports and certificates of conformance are available upon request for qualified buyers.
