Compatible Replacement & Equivalent Models
If the NP1L-RJ1 is discontinued or on extended lead time, the following models may serve as functional equivalents. Always verify electrical and firmware compatibility before substitution:
- FUJI NP1L-RS1 – RS-232C serial communication variant within the same NP1L family
- FUJI NP1L-RS2 – RS-485 multi-drop communication alternative
- FUJI NP1L-ET1 – Ethernet TCP/IP module for NP1L series (if RJ refers to Ethernet)
- Third-party gateways – Protocol converters (e.g., Moxa, Anybus) can bridge legacy FUJI NP1L networks to modern Ethernet/PROFIBUS environments
⚠ Disclaimer: Replacement suitability depends on firmware version, rack configuration, and application requirements. Contact our engineers before ordering a substitute.
Why Choose the Original NP1L-RJ1

Replacement & Compatibility FAQ
Q: Can I use NP1L-RJ1 in a FUJI MICREX-SX rack?
A: No. The NP1L-RJ1 is designed for the NP1L series only. MICREX-SX requires its own communication modules.
Q: Is the NP1L-RJ1 still in production?
A: Availability varies by region. Contact us to check current stock and lead time.
Q: What is the difference between NP1L-RJ1 and NP1L-RS1?
A: The RJ1 uses an RJ-type interface while the RS1 uses RS-232C. They serve different network topologies.
Q: Do you provide installation support?
A: Yes. Our engineers can assist with parameter configuration and system integration remotely.
