Quick Answer: What replaced SFP-XMM-LC-400?
Discontinued: SFP-XMM-LC-400 | Replacement: SFP-XMM-LCI-400
Why B+B SMARTWORX Discontinued the SFP-XMM-LC-400
B+B SMARTWORX SFP-XMM-LC-400 has been identified as EOL in progress based on an Advantech announcement marking the part as End of Life. For buyers searching for SFP-XMM-LC-400, the important point is that the part is still referenced as available, but discontinuation has already been announced. That means procurement teams should treat SFP-XMM-LC-400 as a transitioning product and begin planning for SFP-XMM-LCI-400.
The available research does not provide a published EOL date for SFP-XMM-LC-400, and it also does not include a manufacturer migration document that formally maps SFP-XMM-LC-400 to SFP-XMM-LCI-400. Even so, SFP-XMM-LCI-400 appears in the same product context and is the replacement part identified for sourcing purposes. Because the official timeline and technical migration details were not included in the available search results, IT teams should confirm any deployment-specific requirements with the manufacturer or review full Advantech and B+B SMARTWORX documentation before making large-volume changes.
In practical terms, an EOL in progress status for SFP-XMM-LC-400 means there is risk in waiting. Stock can become limited, lead times can change, and support planning becomes harder once a part enters end-of-life status. If your network design, spare parts strategy, or installed base currently depends on SFP-XMM-LC-400, this is the right time to evaluate SFP-XMM-LCI-400 and update purchasing records accordingly.
What's New in the SFP-XMM-LCI-400
Replacement path for SFP-XMM-LC-400 sourcing
The clearest update is availability direction. SFP-XMM-LC-400 is marked EOL, while SFP-XMM-LCI-400 is the replacement part to evaluate for future purchases. For procurement teams, that makes SFP-XMM-LCI-400 the part number to use in quotes, approved vendor lists, and upcoming replenishment planning where SFP-XMM-LC-400 was previously specified.
Current lifecycle position
A major difference between SFP-XMM-LC-400 and SFP-XMM-LCI-400 is lifecycle status. SFP-XMM-LC-400 is in EOL in progress status, which signals a product already on the path out of the portfolio. SFP-XMM-LCI-400, by contrast, is the active part number being referenced for continued purchasing. For operations teams, lifecycle status matters as much as technical fit because it affects long-term support, stocking strategy, and change management.
Technical differences are not published in the available research
The available search results do not include technical specifications for SFP-XMM-LC-400 or SFP-XMM-LCI-400, and they do not provide a validated side-by-side comparison. That means it would be inaccurate to claim specific differences in optics, reach, connector behavior, compatibility, or environmental ratings. If you need to compare SFP-XMM-LC-400 and SFP-XMM-LCI-400 at the engineering level, the next step is to request the official datasheets or migration guidance from B+B SMARTWORX or Advantech.
What buyers should take from the change
Even without full published specifications, the move from SFP-XMM-LC-400 to SFP-XMM-LCI-400 is significant for asset planning. Teams that continue to buy SFP-XMM-LC-400 may face increasing availability risk. Teams that switch sourcing to SFP-XMM-LCI-400 now can reduce the chance of urgent substitutions later. This is especially relevant for standardized industrial networking environments where approved part numbers must remain consistent across projects and spare inventories.

Upgrade Checklist
- Review where SFP-XMM-LC-400 is currently installed across switches, edge devices, and spare inventories.
- Update internal purchasing records to add SFP-XMM-LCI-400 as the replacement for SFP-XMM-LC-400.
- Check remaining stock and open orders for SFP-XMM-LC-400, since EOL in progress status can affect availability.
- Request official documentation from B+B SMARTWORX or Advantech if you need confirmed compatibility or engineering validation between SFP-XMM-LC-400 and SFP-XMM-LCI-400.
- Verify your host hardware and application requirements before approving SFP-XMM-LCI-400 for production use, especially if your environment is standardized or regulated.
- Qualify SFP-XMM-LCI-400 in any internal test process used for replacement optics or network interface components.
- Revise service and spare strategies so future maintenance events do not depend on the aging SFP-XMM-LC-400 part number.
- Communicate the change to procurement, operations, and field support teams so SFP-XMM-LC-400 is not reordered by default.
Bottom Line
SFP-XMM-LC-400 from B+B SMARTWORX is in EOL in progress status, and SFP-XMM-LCI-400 is the replacement part to review for ongoing purchasing. While the available research does not include full technical migration details, the lifecycle change is clear enough for IT buyers to begin shifting sourcing away from SFP-XMM-LC-400 and toward SFP-XMM-LCI-400.
