Quick Answer: What replaced ESW105-A?
Discontinued: ESW105-A | Replacement: BB-ESW105-A
Why B+B SMARTWORX Discontinued the ESW105-A
The ESW105-A from B+B SMARTWORX is fully discontinued and no longer available for purchase. Based on current research, BB-ESW105-A is the official replacement for ESW105-A and remains available through distribution channels. For buyers searching for ESW105-A stock, the practical answer is that new purchases should move to BB-ESW105-A.
No official reason for the ESW105-A discontinuation has been published in the available manufacturer or distributor sources. There is no stated notice tying the ESW105-A phase-out to a technology refresh, regulatory change, efficiency update, or product redesign. The only confirmed status is that ESW105-A is fully discontinued and no longer for sale, while BB-ESW105-A is the active replacement part.
It is also important for procurement teams to note that no official end-of-life date has been announced for ESW105-A in the sources reviewed. In other words, ESW105-A is already considered unavailable, but there is no published EOL timeline explaining when that status formally began. If your BOM, maintenance plan, or spare parts list still references ESW105-A, it should be updated to BB-ESW105-A.
Because BB-ESW105-A is listed directly alongside ESW105-A by distributors and under Advantech, the successor organization associated with B+B SmartWorx, buyers can treat BB-ESW105-A as the supported path forward when replacing an ESW105-A in current procurement workflows.
What's New in the BB-ESW105-A
Official replacement status for ESW105-A
The most important update is not a published redesign detail but the replacement relationship itself: BB-ESW105-A is the confirmed replacement for ESW105-A. If your team needs to source a currently available alternative to ESW105-A, BB-ESW105-A is the relevant part number to use in purchasing and quoting.
Confirmed current availability
Unlike ESW105-A, which is fully discontinued, BB-ESW105-A remains available from distributors. That makes BB-ESW105-A the active option for organizations supporting installed equipment that originally specified ESW105-A.
Published product description for BB-ESW105-A
Available sources describe BB-ESW105-A as a 5-port unmanaged Fast Ethernet industrial switch. The published descriptions also reference low VAC power input, specifically 10-24 VAC or 12-48 VDC redundant power, along with slim design, wide temperature support, and DIN rail or wall mounting. These details are useful for buyers evaluating BB-ESW105-A for industrial network deployments.
Direct technical differences are not published
Although BB-ESW105-A replaces ESW105-A, the key technical differences between ESW105-A and BB-ESW105-A cannot be confirmed from the available sources. The reason is simple: the research provides descriptive information for BB-ESW105-A, but no equivalent official ESW105-A specifications for side-by-side verification. For that reason, it would be inaccurate to claim performance, mechanical, or electrical changes beyond the documented replacement status and the published BB-ESW105-A description.
- Confirmed: ESW105-A is discontinued.
- Confirmed: BB-ESW105-A is the official replacement.
- Confirmed: BB-ESW105-A is described as a 5-port unmanaged Fast Ethernet industrial switch.
- Not confirmed from sources: exact feature-by-feature differences between ESW105-A and BB-ESW105-A.

Upgrade Checklist
- Search internal ERP, CMMS, and purchasing records for every reference to ESW105-A.
- Update approved vendor lists and BOMs to show BB-ESW105-A as the replacement for ESW105-A.
- Confirm your installed application only requires the documented capabilities published for BB-ESW105-A, including unmanaged Fast Ethernet switching and the listed power input options.
- Review enclosure space and mounting method if your current installation uses DIN rail or wall mounting, since BB-ESW105-A is described as a slim industrial switch with those mounting options.
- Verify site power compatibility against the published BB-ESW105-A input ranges of 10-24 VAC or 12-48 VDC redundant power.
- If your engineering team needs a one-to-one specification comparison between ESW105-A and BB-ESW105-A, flag that the available sources do not provide enough ESW105-A data for a complete technical delta.
- For ongoing support planning, remove expectations of future new-stock availability for ESW105-A, because it is fully discontinued and no longer purchasable.
- Place new orders using the active part number BB-ESW105-A to avoid delays tied to obsolete ESW105-A sourcing attempts.
Bottom Line
ESW105-A is fully discontinued, with no announced EOL date and no published reason for discontinuation in the available sources. BB-ESW105-A is the confirmed replacement part and the correct option for buyers who need a currently available substitute for ESW105-A.
For procurement and maintenance teams, the main action is straightforward: replace ESW105-A references with BB-ESW105-A and validate fit for your application using the published BB-ESW105-A details. Where a strict technical comparison is required, note that the available source data does not provide enough ESW105-A specifications to document all differences.
