Compatible Replacement & Equivalent Models
When the FX1-16MR is discontinued or unavailable, the following models offer functional compatibility or direct drop-in replacement potential. Always verify I/O count, output type, and power supply before substitution.
- Mitsubishi FX1S-14MR-001 — Smaller I/O count (14 pts), same relay output; suitable for space-constrained retrofits
- Mitsubishi FX1N-16MR-001 — Direct upgrade path; expanded memory (8,000 steps), same 16 I/O relay configuration
- Mitsubishi FX2N-16MR-001 — Higher-performance equivalent; supports special function modules and high-speed counters
- Mitsubishi FX3G-14MR/ES — Modern replacement with USB programming port and built-in analog I/O option
- Mitsubishi FX3U-16MR/ES — Premium upgrade; high-speed processing, extensive expansion capability
- Siemens S7-1200 CPU 1212C DC/DC/RLY — Cross-brand alternative for new installations; requires reprogramming
- Omron CP1E-N20DR-A — Cross-brand equivalent with 20 I/O relay output; compatible I/O voltage levels
Note: Cross-brand replacements require program migration and wiring verification. Contact our technical team for assistance.

Selection Guide
Use the following criteria to determine whether the FX1-16MR is the right choice or if an alternative is needed:
- I/O Count ≤ 16 points: FX1-16MR is optimal; for 24+ points, consider FX1N-24MR or FX3G-24MR
- Output Type — Relay: FX1-16MR (suffix MR); for transistor output, select FX1-16MT
- High-Speed Counter Required: Upgrade to FX1N-16MR or FX3U-16MR for built-in HSC support
- Analog I/O Required: Add FX2N-2AD/2DA expansion or upgrade to FX3G with built-in analog
- Network/Fieldbus Required: FX3U with CC-Link or PROFIBUS adapter recommended
- Budget-Constrained Retrofit: FX1-16MR original or FX1N-16MR upgrade offers best cost-performance ratio

Replacement & Compatibility FAQ
Q: Is the FX1N-16MR a direct replacement for the FX1-16MR?
A: Yes, the FX1N-16MR is the most compatible upgrade. It shares the same 16 I/O relay output configuration and is backward-compatible with FX1 programs with minor adjustments in GX Developer.
Q: Can I use FX3G or FX3U to replace the FX1-16MR?
A: Functionally yes, but these are newer-generation CPUs. Program migration from FX1 to FX3 series is straightforward in GX Works2, though wiring and expansion module compatibility should be verified.
Q: Is the FX1-16MR still in production?
A: The FX1 series has been discontinued by Mitsubishi Electric. Konmask.com maintains stock of new-old-stock (NOS) and tested surplus units. We recommend the FX1N or FX3G series for new designs.
Q: What is the difference between FX1-16MR and FX1-16MT?
A: The suffix “MR” denotes relay output; “MT” denotes transistor (NPN) output. Relay outputs handle AC/DC loads and are more robust for general switching; transistor outputs are faster and suited for high-frequency switching and servo/stepper applications.
Q: Do you provide programming support or migration assistance?
A: Yes. Our technical team can assist with program backup, migration guidance, and compatibility verification. Contact [email protected] with your project details.
