Compatible Replacement & Equivalent Models
When the SNT501-13 is discontinued, on extended lead time, or budget-constrained, the following alternatives may be evaluated. Always verify electrical and protocol compatibility before substitution.
- YOKOGAWA SNT501-11 — Bus Repeater Master Module (paired counterpart; different role but same bus family)
- YOKOGAWA SNT501-12 — Alternate slave variant; confirm firmware revision compatibility
- YOKOGAWA F3SP28-3N / F3SP38-6N — For migration to FACTORY ACE platform; requires system re-engineering
- Third-party STARDOM-compatible repeaters — Must support YOKOGAWA proprietary bus protocol; not recommended without factory approval

Selection Guide
Use the following criteria to confirm the SNT501-13 is the correct module for your application:
- Step 1 — Identify your controller: Confirm your system uses STARDOM FCN or FCJ. Check the chassis label or system documentation.
- Step 2 — Determine bus role: SNT501-13 is a Slave module. Ensure a corresponding Master module (e.g., SNT501-11) is present in the segment.
- Step 3 — Count bus segments: Each repeater pair extends one bus segment. Calculate total segment count to determine quantity needed.
- Step 4 — Check firmware revision: Verify your FCN/FCJ firmware version supports the SNT501-13 hardware revision. Refer to YOKOGAWA release notes.
- Step 5 — Environmental rating: Confirm ambient temperature, humidity, and vibration specs match your installation site.

Replacement & Compatibility FAQ
Q: Can the SNT501-13 replace the SNT501-11?
A: No. The SNT501-11 is the Master module and the SNT501-13 is the Slave. They work as a pair and are not interchangeable.
Q: Is the SNT501-13 compatible with CENTUM VP?
A: No. The SNT501-13 is exclusively designed for the STARDOM FCN/FCJ platform. CENTUM VP uses a different bus architecture.
Q: Can I use a third-party bus repeater as a replacement?
A: Third-party replacements are generally not recommended due to YOKOGAWA’s proprietary bus protocol. Contact Konmask.com for verified alternatives.
Q: What is the warranty on surplus/refurbished units?
A: Konmask.com offers a 90-day functional warranty on tested surplus units. New OEM units carry the standard YOKOGAWA manufacturer warranty.
Q: How do I verify authenticity?
A: All units include serial number documentation. We provide traceability records and can assist with YOKOGAWA factory verification upon request.
