Quick Answer: What replaced IMC-390-SM-PS?
Discontinued: IMC-390-SM-PS | Replacement: IMC-390-SM
Why B+B SMARTWORX Discontinued the IMC-390-SM-PS
Based on available research, B+B SMARTWORX has not published a direct announcement confirming why the IMC-390-SM-PS is being discontinued or whether it is fully end-of-life. The current status should be treated as EOL in progress: IMC-390-SM-PS may still be available for purchase, but buyers should expect lifecycle risk because discontinuation has been indicated without a confirmed public timeline.
It is important to be precise here. No official manufacturer notice was found that names IMC-390-SM as the formal replacement for IMC-390-SM-PS. However, in channel and product-listing context, IMC-390-SM is the practical successor part that buyers are being directed to when planning new purchases. For procurement teams, that means the safest approach is to stop specifying IMC-390-SM-PS for new projects and validate IMC-390-SM for current requirements instead.
Research also did not identify a published EOL date for IMC-390-SM-PS, nor a stated reason such as a platform refresh, component availability issue, regulatory change, or product line consolidation. Similar B+B SMARTWORX media converter models have been discontinued, which suggests broader portfolio transition may be a factor, but that cannot be confirmed for IMC-390-SM-PS specifically.
What's New in the IMC-390-SM
Replacement path for ongoing availability
The most relevant change for buyers is not a published feature addition but the fact that IMC-390-SM is the part currently positioned for ongoing sourcing, while IMC-390-SM-PS carries lifecycle uncertainty. If you are supporting installed equipment, IMC-390-SM-PS may still be obtainable in the short term, but IMC-390-SM is the better candidate for forward-looking procurement.
No confirmed manufacturer-published spec changes
No verified comparison data was found that documents technical differences between IMC-390-SM-PS and IMC-390-SM. That means buyers should avoid assuming changes in fiber type, connector type, port count, power method, operating environment, or management features unless they are validated from current product documentation or supplier quotes. For engineering teams, this is a key point: treat IMC-390-SM as a replacement path, not as a spec-identical substitute, until reviewed.
Lifecycle planning is the main update
In practical terms, the biggest difference between IMC-390-SM-PS and IMC-390-SM may be commercial rather than technical. IMC-390-SM-PS is tied to an announced discontinuation status without a published end date, while IMC-390-SM remains available in the market. For organizations managing spares, framework agreements, or multi-site rollouts, this affects standardization, lead-time planning, and support strategy.
What buyers should verify before ordering
- Whether IMC-390-SM matches the required network media conversion use case of IMC-390-SM-PS.
- Whether power supply scope or powering method differs between IMC-390-SM-PS and IMC-390-SM.
- Whether optical characteristics and connector requirements are identical for the intended deployment.
- Whether mounting, environmental, and certification needs remain covered.
- Whether your internal BOM, approved vendor list, and spare stock policy should be updated from IMC-390-SM-PS to IMC-390-SM.
At-a-Glance Comparison
| Feature | IMC-390-SM-PS | IMC-390-SM |
|---|---|---|
| Manufacturer | B+B SMARTWORX | B+B SMARTWORX |
| Lifecycle status | EOL in progress; still available but discontinuation indicated | Available product |
| Official manufacturer EOL notice found | No direct confirmation found in available research | Not applicable |
| Official replacement announcement found | No manufacturer announcement confirming IMC-390-SM as replacement | No explicit manufacturer replacement link found |
| EOL date | Not announced | Not announced |
| Reason for discontinuation | Not publicly confirmed | Not applicable |
| Published technical differences vs. other part | No verified comparison data found | No verified comparison data found |
| Recommended sourcing approach | Use for support/spares only if needed and available | Prefer for new quotes and future deployments |
Upgrade Checklist
- Audit current usage. Identify every site, panel, and BOM where IMC-390-SM-PS is installed or specified.
- Confirm actual availability. Because IMC-390-SM-PS is in EOL progress rather than fully ended, check current stock and lead time before committing to support plans.
- Validate replacement fit. Review IMC-390-SM against your required interface, optical path, power arrangement, and deployment conditions.
- Do not assume identical specifications. No verified technical comparison between IMC-390-SM-PS and IMC-390-SM was found, so engineering sign-off is recommended.
- Update purchasing records. Replace IMC-390-SM-PS with IMC-390-SM in approved part lists, RFQs, and standard designs where appropriate.
- Plan spare coverage. If IMC-390-SM-PS supports an installed base, consider last-buy planning while inventory is still available.
- Document the lifecycle change. Record that IMC-390-SM-PS has a discontinuation notice without a published EOL date, so future supply may tighten with limited notice.
- Source through a trusted reseller. Working with a reseller helps confirm current availability of IMC-390-SM and supports transition planning from IMC-390-SM-PS.
Bottom Line
For buyers searching for the next step after IMC-390-SM-PS, the practical replacement is IMC-390-SM, even though no official manufacturer notice was found that explicitly links the two part numbers. Because IMC-390-SM-PS is in EOL progress and no public end date or technical comparison has been confirmed, the right approach is to validate IMC-390-SM carefully and move new purchasing activity to the currently available part.
If your team still relies on IMC-390-SM-PS, now is the time to review stock strategy, replacement qualification, and procurement records so supply risk does not affect future projects or maintenance windows.
