Compatible Replacement & Equivalent Models
If the NFPW442-11 S2 is unavailable or you are evaluating alternatives, the following models may serve as functional equivalents depending on your system configuration:
- Yokogawa NFPW441-11 – Earlier revision; verify firmware and backplane compatibility before substitution.
- Yokogawa NFPW442-11 S1 – Previous suffix revision; functionally similar, confirm hardware revision with your system integrator.
- Yokogawa NFPW482-11 – Higher-capacity power supply for expanded I/O configurations.
- Third-party DCS power supplies – Must match voltage, current rating, and connector pinout exactly. Not recommended without engineering validation.
⚠ Always verify part suffix, hardware revision, and system compatibility before substituting power supply modules in live DCS environments.

Selection Guide
Use the following criteria to confirm the NFPW442-11 S2 is the correct module for your application:
- Step 1 – Confirm DCS platform: Verify your system is CENTUM VP or CS 3000.
- Step 2 – Check input voltage: Confirm 24 VDC supply availability at the cabinet.
- Step 3 – Count I/O load: Ensure the module output capacity covers your FCS I/O count.
- Step 4 – Verify suffix revision: S2 suffix indicates the current production revision — do not substitute S1 without engineering sign-off.
- Step 5 – Redundancy requirement: If N+1 redundancy is required, order a second unit and confirm your FCS supports dual power input.
