Quick Answer: What replaced BB-806-39720?
Discontinued: BB-806-39720 | Replacement: B+B SMARTWORX
Why IMC-370-SST-PS-A Discontinued the BB-806-39720
IMC-370-SST-PS-A reached full discontinuation after the 2024-06-30 last shipment deadline. According to manufacturer EOL information, the discontinuation was driven by portfolio consolidation, termination of a slow-moving model, and marketing strategy. For buyers searching BB-806-39720, it is important to separate the discontinued assembled unit from the active replacement power component.
The official manufacturer transition was not a direct one-part swap of the full IMC-370-SST-PS-A assembly. Instead, the original unit with built-in power supply was replaced by a newer configuration. The official replacement media converter is IMC-370I-SST-B, while BB-806-39720 serves as the external MiniMc AC power adapter. In other words, IMC-370-SST-PS-A is discontinued, but BB-806-39720 itself remains an active part used in the replacement path.
This distinction matters for procurement teams. If your records show IMC-370-SST-PS-A or similar legacy entries under B+B SmartWorx, you should not expect to source the original integrated version anymore. The current path is to order the replacement configuration under B+B SMARTWORX or Advantech branding, depending on how your supplier catalogs the line. For complete functional replacement, the manufacturer guidance points to IMC-370I-SST-B + BB-806-39720.
What's New in the B+B SMARTWORX
IMC-370I-SST-B is the official replacement media converter
The main product change is that the discontinued IMC-370-SST-PS-A has been replaced at the converter level by IMC-370I-SST-B. This is the official media converter replacement identified in the manufacturer EOL notice. If you are replacing the original hardware platform, this is the core device to review.
BB-806-39720 is now a separate power component
Under the replacement approach, BB-806-39720 is the power component rather than the complete replacement device. The part is an external MiniMc AC power adapter for IMC-350 and IMC-370 series applications. This is why searches for BB-806-39720 often appear alongside B+B SMARTWORX replacement guidance.
No built-in power supply in IMC-370I-SST-B
A key difference in the new configuration is that IMC-370I-SST-B does not have a built-in power supply. That is the practical change buyers need to plan for when replacing IMC-370-SST-PS-A. The older integrated setup is no longer available for purchase, so power provisioning now requires the separate BB-806-39720 adapter.
B+B SMARTWORX sourcing is about the replacement path, not a single like-for-like SKU
When Tecisoft and other suppliers point buyers to B+B SMARTWORX, that should be read as the current replacement family or sourcing path. For many customers, the procurement task is not “find the same IMC-370-SST-PS-A again,” but “source the supported B+B SMARTWORX replacement combination that restores the same function.” In practical terms, that means confirming whether you need only BB-806-39720 as a power adapter or the full replacement set of IMC-370I-SST-B + BB-806-39720.
At-a-Glance Comparison
| Feature | BB-806-39720 | B+B SMARTWORX |
|---|---|---|
| Availability status | Active, orderable part based on current manufacturer and distributor data | Current replacement sourcing path for the discontinued IMC-370-SST-PS-A platform |
| Role in replacement | External power component | Replacement family/brand path for supported migration |
| Official function | MiniMc AC power adapter for IMC-350 and IMC-370 series | Associated with the official replacement combination IMC-370I-SST-B + BB-806-39720 |
| Built-in power supply | No, external adapter | Replacement converter IMC-370I-SST-B does not include built-in power |
| What changed from IMC-370-SST-PS-A | Power is now separated into BB-806-39720 | The replacement design moves from integrated power to modular converter + adapter |
| Discontinuation context | Not discontinued based on current findings | Used as the migration path after IMC-370-SST-PS-A full discontinuation on 2024-06-30 |
Upgrade Checklist
- Verify whether your installed unit is IMC-370-SST-PS-A and not just the separate BB-806-39720 power adapter.
- Check your asset records for the EOL timeline: announcement 2023-04-01, phase-out 2023-12-30, last time buy 2024-03-30, and last shipment 2024-06-30.
- For a full hardware replacement, plan around the official combination of IMC-370I-SST-B + BB-806-39720.
- Confirm power architecture changes because IMC-370I-SST-B does not include a built-in power supply.
- If you only need the external power component for a supported configuration, confirm that BB-806-39720 remains the correct MiniMc AC power adapter.
- Standardize purchasing language across teams by referencing both BB-806-39720 and B+B SMARTWORX in RFQs and internal approvals.
- Work with your supplier to confirm current branding, since B+B SmartWorx products may also appear under Advantech listings.
- Use a current source for procurement to avoid accidental orders for the fully discontinued IMC-370-SST-PS-A assembly.
Bottom Line
IMC-370-SST-PS-A is fully discontinued, and the supported migration path is not the old integrated unit. For most buyers, the correct replacement route is the B+B SMARTWORX family using IMC-370I-SST-B + BB-806-39720, with BB-806-39720 handling the external power function.
If your team is searching for BB-806-39720 as a replacement, make sure you match the requirement correctly: adapter-only needs are different from complete converter replacement. That is the key change introduced by the B+B SMARTWORX transition.
