Quick Answer: What replaced IMC-390-MM-PS?
Discontinued: IMC-390-MM-PS | Replacement: IMC-390-MM
Why B+B SMARTWORX Discontinued the IMC-390-MM-PS
The B+B SMARTWORX IMC-390-MM-PS is fully discontinued and no longer available for purchase. Based on the available research, the clearest lifecycle signal is that Mouser Electronics lists IMC-390-MM-PS as Obsolete. No public manufacturer notice, end-of-life bulletin, or distributor timeline in the provided research gives a specific EOL date for IMC-390-MM-PS, so the exact discontinuation date remains unannounced.
It is also important to be precise about the reason. The available research does not provide an official explanation from B+B SMARTWORX for why IMC-390-MM-PS was discontinued. For procurement teams and engineers, that means the safest statement is that IMC-390-MM-PS has reached obsolete status in distribution, rather than claiming a confirmed technical or strategic reason that is not documented in the source material.
In practice, when a part such as IMC-390-MM-PS is marked obsolete, buyers should treat it as unavailable for new projects and avoid building future deployments around it. For organizations still supporting installed equipment, the next step is to evaluate the listed replacement path to IMC-390-MM while also confirming compatibility directly with current Advantech or B+B SMARTWORX documentation if the application is sensitive.
What's New in the IMC-390-MM
Replacement path for new purchasing
The main update is commercial rather than a documented feature change: IMC-390-MM is the part number to target for current sourcing when IMC-390-MM-PS is no longer available. For IT purchasing teams, this matters because quotes, ERP records, and approved vendor lists should be updated from IMC-390-MM-PS to IMC-390-MM to avoid delays caused by obsolete inventory searches.
Limited published differentiation in available research
The provided research does not include an official side-by-side specification comparison between IMC-390-MM-PS and IMC-390-MM. It indicates that both part numbers appear in distributor listings and that both are described as PoE+ media converters with multimode 850nm fiber support. Beyond that, the search results do not document specific differences in ports, power options, management features, environmental ratings, or performance.
What buyers should assume—and not assume
Because the source material does not confirm detailed technical changes, buyers should not assume that IMC-390-MM is identical to IMC-390-MM-PS in every deployment detail. The replacement IMC-390-MM may be the correct commercial successor, but technical teams should still verify any installation-specific requirements such as power method, connector expectations, fiber type, and interoperability with the existing network design before ordering in volume.
Why verification matters in industrial and edge environments
Media converter replacements can affect field deployments if any undocumented difference exists. If you are replacing an installed IMC-390-MM-PS in a plant, campus, or remote cabinet environment, review the current product documentation for IMC-390-MM and compare it against your as-built records. That is especially important when the original BOM references IMC-390-MM-PS and the application depends on a specific power arrangement or installation method.
At-a-Glance Comparison
| Feature | IMC-390-MM-PS | IMC-390-MM |
|---|---|---|
| Manufacturer | B+B SMARTWORX | B+B SMARTWORX |
| Lifecycle status | Fully discontinued; listed as Obsolete by Mouser | Replacement part for purchasing |
| Availability | No longer available for purchase | Current part to source |
| Official EOL date | Not announced in provided research | Not applicable in provided research |
| Official manufacturer replacement notice | Not included in provided research | Not included in provided research |
| Known product type in available research | PoE+ media converter | PoE+ media converter |
| Known fiber detail in available research | Multimode, 850nm | Multimode, 850nm |
| Documented technical differences | Not provided in search results | Not provided in search results |
| Procurement recommendation | Do not use for new purchasing | Use for current sourcing, with compatibility review |
Upgrade Checklist
- Update your BOMs and ERP records. Replace IMC-390-MM-PS with IMC-390-MM in internal purchasing systems so obsolete part numbers do not block reorder workflows.
- Review the installed application. Confirm where IMC-390-MM-PS is deployed and whether each location has any special power, cabling, or environmental constraints.
- Verify current documentation. Before standardizing on IMC-390-MM, check official Advantech or B+B SMARTWORX documentation to confirm fit for your exact use case.
- Validate fiber and network assumptions. The available research shows both IMC-390-MM-PS and IMC-390-MM as multimode 850nm PoE+ media converters, but application-specific settings should still be confirmed.
- Plan for service inventory. If you still have live IMC-390-MM-PS units in the field, decide whether to hold spares temporarily or move directly to IMC-390-MM as the service replacement.
- Coordinate with procurement and engineering. Make sure both teams understand that IMC-390-MM-PS is obsolete and that IMC-390-MM is the part to evaluate for future orders.
- Source from a trusted reseller. Buying IMC-390-MM through an established IT supplier helps streamline quoting and availability checks for replacement projects.
Bottom Line
IMC-390-MM-PS is fully discontinued and should be treated as an obsolete B+B SMARTWORX part number for procurement purposes. IMC-390-MM is the replacement part to source, but the available research does not document a detailed technical delta, so buyers should verify application fit before rollout. For new purchasing, the practical move is to transition from IMC-390-MM-PS to IMC-390-MM now.
