Quick Answer: What replaced IMC-390-M1-PS?
Discontinued: IMC-390-M1-PS | Replacement: IMC-390-SFP
Why B+B SMARTWORX Discontinued the IMC-390-M1-PS
B+B SMARTWORX has not published a specific discontinuation notice, EOL date, or formal replacement statement for IMC-390-M1-PS in the research provided. The current status should therefore be treated as EOL in progress: the IMC-390-M1-PS may still be available for purchase, but a discontinuation has been indicated and buyers should plan ahead.
It is important to be precise here. No official manufacturer source in the research confirms why IMC-390-M1-PS is being phased out. There is also no confirmed last-time-buy date, no announced end-of-support date, and no published retirement schedule tied specifically to this part number. Broader B+B SmartWorx and IMC Networks product family notices exist for other models, but they do not explicitly list IMC-390-M1-PS.
For procurement teams, that means the practical issue is supply continuity rather than a fully documented lifecycle event. If your design, maintenance plan, or spare stock currently depends on IMC-390-M1-PS, this is the right time to evaluate IMC-390-SFP as the working successor option, while also confirming fit with your deployment requirements.
What's New in the IMC-390-SFP
Replacement positioning for IMC-390-M1-PS
The research does not confirm that IMC-390-SFP is an official manufacturer-declared replacement for IMC-390-M1-PS. However, because buyers are actively looking for a current alternative tied to the IMC-390 family, IMC-390-SFP is the replacement part being used for sourcing and transition planning in this context. If you are standardizing on a currently searchable part number, IMC-390-SFP is the model to review.
Technical differences are not fully published
One key limitation is that the available research does not provide enough verified specification data to build a complete side-by-side technical comparison between IMC-390-M1-PS and IMC-390-SFP. There is an IMC-390 series manual referenced in the findings, but no confirmed variant-level feature mapping for these two exact part numbers. That means buyers should avoid assuming port type, optical support, power details, or feature parity without checking current documentation or installed hardware labels.
SFP naming indicates a different interface approach
Based on part-number naming only, IMC-390-SFP strongly suggests an SFP-based variant, while IMC-390-M1-PS appears to be a different configuration within the same family. That said, the research does not verify the exact operational differences, so this should be treated as an indicator rather than a published spec. For engineering teams, the practical takeaway is to confirm module compatibility, fiber type, and link design before replacing IMC-390-M1-PS with IMC-390-SFP in production.
Planning matters more than published EOL detail
Because no formal EOL timeline has been announced for IMC-390-M1-PS, organizations should focus on proactive migration planning. If you need ongoing availability for projects or sparing, moving evaluation efforts toward IMC-390-SFP reduces the risk of a supply gap later. This is especially relevant for industrial networking environments where long refresh cycles are common.

Upgrade Checklist
- Identify every installed location where IMC-390-M1-PS is in service, including production links, lab systems, and spare inventory.
- Check whether your current network design depends on a fixed fiber interface or a modular interface before selecting IMC-390-SFP.
- Review available documentation for your exact IMC-390 deployment so you do not assume that IMC-390-M1-PS and IMC-390-SFP are identical.
- Confirm optical requirements such as fiber type, distance, and module compatibility if you plan to move to IMC-390-SFP.
- For procurement, secure any remaining IMC-390-M1-PS units needed for short-term support while qualifying IMC-390-SFP for future purchases.
- Update internal approved vendor lists, BOMs, and maintenance records so the transition from IMC-390-M1-PS to IMC-390-SFP is documented.
- Before large rollouts, test IMC-390-SFP in one representative site or link segment to confirm interoperability with your existing environment.
Bottom Line
The available research shows that IMC-390-M1-PS should be treated as a part in transition, but without a published B+B SMARTWORX EOL date, reason, or formal replacement notice. For buyers needing a current sourcing path, IMC-390-SFP is the practical replacement option to evaluate, with the important caveat that technical equivalence has not been fully confirmed in the provided data.
If you rely on IMC-390-M1-PS, the safest approach is to plan your migration early, verify compatibility carefully, and avoid waiting for supply constraints to force a rushed change. That will give your team time to qualify IMC-390-SFP properly and keep projects moving.
