Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional replacements or equivalents for the SE4301T02. Always verify electrical and mechanical compatibility before substitution:
- EMERSON KL3003X1-BA2 — Revised revision of the same power supply family; confirm firmware compatibility
- EMERSON 12P4632X142 — Alternate part number variant; verify backplane pinout
- EMERSON VE4001S2T2B4 — DeltaV S-series power supply; check chassis generation compatibility
- Rockwell Allen-Bradley 1756-PA75 — Cross-platform alternative for ControlLogix environments (not a direct drop-in)
- Siemens 6ES7 307-1EA01-0AA0 — SIMATIC S7-300 power supply; suitable only if migrating platform
Note: Cross-brand equivalents require full engineering review. Contact our technical team for application-specific guidance.

- Pulp, paper, and water treatment facilities
- Refinery and pipeline SCADA/DCS hybrid architectures
System Compatibility
- Primary Platform: EMERSON DeltaV DCS (S-series, M-series controllers)
- Backplane: DeltaV standard 2-wide, 4-wide, and 8-wide carrier modules
- Communication Protocol: DeltaV internal bus (not standalone Modbus/PROFIBUS)
- Software: Compatible with DeltaV Operate and DeltaV Diagnostics
- Not Compatible With: Ovation DCS, ROC800 RTU, or non-EMERSON backplanes without engineering adaptation
Selection Guide
Use the following criteria to determine whether the SE4301T02 or an alternative is the right choice for your application:
- Step 1 — Confirm Platform: Verify your controller is DeltaV S-series or M-series. Check the existing backplane part number.
- Step 2 — Check Revision: Compare the hardware revision (Rev A/B/C) on the existing module label. Mismatched revisions may require firmware updates.
- Step 3 — Assess Condition Requirement: Safety-critical loops → specify New OEM. Non-critical auxiliary power → Refurbished/Tested Used acceptable.
- Step 4 — Evaluate Lead Time vs. Cost: New OEM has longest lead time; refurbished stock ships faster. Contact us for current availability.
- Step 5 — Cross-Brand Migration: Only consider cross-brand equivalents if performing a full platform migration with engineering sign-off.

Replacement & Compatibility FAQ
Q: Can I use KL3003X1-BA2 as a direct replacement for KL3003X1-BA1?
A: In most cases yes, as they are revision variants of the same module family. However, confirm with your DeltaV system version and check for any firmware dependency notes in the EMERSON release notes.
Q: Is the SE4301T02 still in production?
A: EMERSON periodically revises DeltaV hardware. Contact us to confirm current OEM production status and available stock condition (new vs. refurbished).
Q: Can this module be used in a non-DeltaV system?
A: The SE4301T02 is designed specifically for DeltaV backplanes. Use in other systems is not supported without significant engineering adaptation.
Q: What is the lead time for a new unit?
A: Lead times vary by stock condition. Refurbished units typically ship within 3–7 business days. New OEM units may require 4–12 weeks depending on EMERSON availability. Contact us for real-time stock status.
Q: Do you provide a test report?
A: Yes. Functional test reports are available for refurbished units upon request at time of order.
