Quick Answer: What replaced IMC-370-SFP-PS-B?
Discontinued: IMC-370-SFP-PS-B | Replacement: IMC-370I-SFP-C
Why B+B SMARTWORX Discontinued the IMC-370-SFP-PS-B
B+B SMARTWORX announced the discontinuation of IMC-370-SFP-PS-B as part of a product transition tied to improved lead-time IC solutions and added functionality in newer models. Research indicates the IMC-370-SFP-PS-B moved through phase-out on 2023-12-30, last-time-buy on 2024-03-30, and last shipment on 2024-06-30, with end of support extending to 2026.
For IT buyers, that means IMC-370-SFP-PS-B should now be treated as an end-of-life part for new project planning, even if some channel references still describe the status as “EOL in progress.” The key business reason for the change was component strategy: B+B SMARTWORX moved toward better lead-time IC availability while also updating the feature set in the replacement family.
It is also important to note a detail from the research: the officially suggested replacement for IMC-370-SFP-PS-B is listed as IMC-370I-SFP-B + BB-806-39720. Separately, B-version IMC-370I-SFP-B models are being superseded by IMC-370I-SFP-C variants. As a result, many buyers searching for the current path forward will end up evaluating IMC-370I-SFP-C as the newer replacement direction for deployments previously built around IMC-370-SFP-PS-B.
In practical terms, if your team is replacing failed IMC-370-SFP-PS-B units, standardizing new installs, or aligning spare inventory with currently advancing part families, IMC-370I-SFP-C is the part number you should review now.
What's New in the IMC-370I-SFP-C
Addition of Power Delivery function
One of the main changes associated with the newer replacement models is the addition of Power Delivery (PD) functionality. This is part of the broader update that differentiates the newer IMC-370I-SFP-C generation from older IMC-370-SFP-PS-B-era options.
Gigabit fiber optic links in Force mode
The research highlights support for Gigabit Fiber Optic Links in Force mode as a key enhancement. Earlier B-version behavior supported Auto mode only, while the newer C-version path adds Force mode support. For engineers and network teams, this matters in environments where link behavior must be explicitly controlled rather than left to automatic negotiation behavior.
Improved lead-time IC solutions
Supply continuity is often just as important as technical fit. The IMC-370I-SFP-C transition is tied to improved lead-time IC solutions, which helps explain why B+B SMARTWORX retired IMC-370-SFP-PS-B. For procurement teams, this is a practical reason to move away from IMC-370-SFP-PS-B and toward an actively advanced replacement family.
Alignment with the IMC-350I series feature set
B+B SMARTWORX also used this change to align the IMC-370I family more closely with the IMC-350I series feature set. That kind of platform alignment can simplify mixed-environment support and make future standardization easier across industrial networking deployments.

Upgrade Checklist
- Confirm installed part numbers. Audit sites and spares to identify every IMC-370-SFP-PS-B unit in service, in stock, or listed on maintenance contracts.
- Review the replacement path carefully. Research shows the official suggested replacement for IMC-370-SFP-PS-B was IMC-370I-SFP-B + BB-806-39720, while IMC-370I-SFP-C represents the newer superseding direction. Verify the exact bill of materials your project requires.
- Check link-mode requirements. If your application depends on Gigabit Fiber Optic Links in Force mode, confirm that the move away from IMC-370-SFP-PS-B to IMC-370I-SFP-C matches your network design intent.
- Validate power and deployment needs. Because the replacement family adds Power Delivery functionality, review whether that affects your installation plan, cabling expectations, or standard operating configuration.
- Plan around support dates. Since IMC-370-SFP-PS-B is already beyond LTB and last shipment milestones, avoid using it for new projects or long-term spare strategies.
- Standardize future purchasing. For consistency across procurement and support teams, update internal ERP, CMDB, and approved vendor lists from IMC-370-SFP-PS-B to the currently accepted replacement path.
- Work with an authorized reseller. If you need help sourcing IMC-370I-SFP-C or confirming whether it is correct for your environment, use a reseller that can help validate the current part-number transition.
Bottom Line
IMC-370-SFP-PS-B has reached end-of-life, and organizations still using IMC-370-SFP-PS-B should move their planning toward the newer IMC-370I-SFP-C path. The main drivers are improved lead-time IC solutions, added Power Delivery functionality, and support for Gigabit Fiber Optic Links in Force mode.
Because the research notes an intermediate official replacement of IMC-370I-SFP-B + BB-806-39720 before C-version supersession, buyers should verify the exact migration path for their deployment. For most current sourcing conversations, IMC-370I-SFP-C is the part number to review.
