Quick Answer: What replaced USB-4718-AE?
Discontinued: USB-4718-AE | Replacement: ADAM-4018+-F
Why B+B SMARTWORX Discontinued the USB-4718-AE
B+B SMARTWORX USB-4718-AE is in EOL in progress status. That means the USB-4718-AE is still available for purchase in some channels, but Advantech has already announced its End of Life. Based on the research provided, the confirmed reason is straightforward: Advantech has announced the End of Life for USB-4718-AE. No further public reason was included in the available research results.
It is also important to be precise about what is known and what is not. The available research confirms that USB-4718-AE is EOL, but it does not provide a published final last-buy date, last-ship date, or full discontinuation timeline. The EOL date for USB-4718-AE has not been announced in the research data supplied here.
For buyers, maintenance teams, and OEMs that still specify USB-4718-AE, this matters because EOL in progress often creates a limited transition window. During that window, stock may still exist, but planning should move toward the replacement part ADAM-4018+-F. If USB-4718-AE is built into an active system, it is a good time to review spare inventory, support requirements, and integration impact before availability becomes more constrained.
What's New in the ADAM-4018+-F
Replacement planning starts with what is confirmed
The main confirmed change is the product transition itself: USB-4718-AE is being phased out, and ADAM-4018+-F is the replacement part identified for procurement. Because the supplied research does not include a complete ADAM-4018+-F specification sheet, it is important not to assume one-to-one feature parity without review. For purchasing teams, the correct next step is to validate the required I/O, communications method, power design, and mounting needs before swapping USB-4718-AE for ADAM-4018+-F in an existing design.
USB-4718-AE known specifications
The supplied research does provide reference specifications for USB-4718-AE. These known USB-4718-AE details are useful when evaluating ADAM-4018+-F as a replacement:
- 8 thermocouple input channels with 16-bit resolution
- ±0.1% input range accuracy
- 2,500 VDC isolation
- 8 isolated digital input/output channels
- 10 S/s sampling rate, or 1.25 S/s per channel
- Bus-powered through USB 2.0
- Operating temperature range of 0 to 60°C
Interface and installation considerations
One practical difference buyers should review closely is the product family change. USB-4718-AE is clearly a USB device, and the replacement part number ADAM-4018+-F belongs to a different platform naming convention. Even without adding unverified specifications, that naming difference alone signals that migration from USB-4718-AE to ADAM-4018+-F may involve changes in how the module is connected, powered, or installed in the panel or system architecture.
Why this matters for engineers and procurement
If your project depends on the exact USB behavior of USB-4718-AE, do not treat ADAM-4018+-F as a drop-in replacement until your team confirms compatibility. If your priority is lifecycle continuity, however, moving purchasing activity from USB-4718-AE to ADAM-4018+-F now can reduce risk. This is especially relevant for spare parts planning, long-term maintenance contracts, and new builds that should avoid introducing an EOL product.

Upgrade Checklist
- Identify every installed USB-4718-AE unit. Check control panels, lab stations, OEM assemblies, and spare inventory.
- Confirm lifecycle exposure. Because USB-4718-AE is EOL in progress, review open projects that still specify USB-4718-AE and decide whether to transition them to ADAM-4018+-F.
- Map required functions. Document how your current USB-4718-AE is used, including thermocouple channel count, digital I/O usage, isolation needs, sampling expectations, and environmental conditions.
- Review interface impact. USB-4718-AE is bus-powered via USB 2.0. Before moving to ADAM-4018+-F, verify connection method, power requirements, and installation implications.
- Validate software and driver dependencies. If your application, HMI, SCADA, or test software communicates directly with USB-4718-AE, confirm what changes may be needed for ADAM-4018+-F.
- Plan qualification testing. Run a bench test before field deployment to confirm signal handling, response time, and integration with your existing control logic.
- Adjust documentation. Update BOMs, maintenance manuals, spare part lists, and procurement records from USB-4718-AE to ADAM-4018+-F.
- Buy before supply tightens. If you still need USB-4718-AE for short-term support, consider securing remaining stock while also starting the move to ADAM-4018+-F.
Bottom Line
USB-4718-AE has entered End of Life, and the practical replacement path is ADAM-4018+-F. The key point for technical buyers is that USB-4718-AE remains available for now, but the discontinuation has been announced and no EOL date was provided in the supplied research.
For the smoothest transition, treat ADAM-4018+-F as the forward-looking option and verify application fit before replacing USB-4718-AE in production systems. This helps reduce lifecycle risk while keeping procurement aligned with currently supported hardware.
