Key takeaways
- 53 of the 72 PowerFlex 4 / 40 catalog numbers below are Discontinued on their own Rockwell product page; 19 catalog numbers are still Active.
- Rockwell's product pages name a replacement catalog number for 53 of them (the table shows each one); Rockwell's migration path is PowerFlex 523 (25A) and PowerFlex 525 (25B).
- The stock column is live: what we have on the shelf now, at the price you pay.
Rockwell's migration path
- For each PowerFlex 4 and PowerFlex 40 catalog number on this page that Rockwell lists as Discontinued, its product page names a replacement catalog number: a PowerFlex 523 (25A) for a PowerFlex 4 and a PowerFlex 525 (25B) for a PowerFlex 40. (source)
- Rockwell's PowerFlex 40 and 40P Drives to PowerFlex 525 Drives migration guide (publication PFLEX-AP011) compares the two drives' specifications, dimensions, power and control terminals, wiring and parameters. (source)
- Rockwell's VFD migration page lists the PowerFlex 523 and 525 among the current PowerFlex drives it recommends moving to from previous-generation drives. (source)
- The PowerFlex 40 IP66/NEMA 4X versions on this page (catalog numbers ending C104) are still Active on their Rockwell product pages. (source)
Where Rockwell's product page names no replacement for a catalog number, we don't name one either: check the migration guide for that number, or ask us.

Sources: every status, date, replacement category and product-page replacement in the tables comes from Rockwell Automation's own product page for that catalog number, read on October 17, 2026. The migration path comes from: 22B-D4P0N104 (Rockwell Automation product page); PowerFlex 40 and 40P Drives to PowerFlex 525 Drives migration guide, publication PFLEX-AP011C-EN-P (September 2023); VFD & Servo Drive Migration (Rockwell Automation page); 22B-D2P3C104 (Rockwell Automation product page). Statuses change: before you buy or plan a migration, check the current status on Rockwell's product lifecycle search.
More on what each status means and the dates by family: our Allen-Bradley PowerFlex 4 and PowerFlex 40 lifecycle guide.
Keep it running or migrate?
Many plants do both: spares for the PowerFlex 4 / 40 drives that must keep running, and a dated plan to move off the platform. Our PowerFlex 525 vs PowerFlex 40 guide covers identifying the drive you have, what is different on the 525 and when a like-for-like spare makes more sense. Every unit we stock is photographed; check the series and firmware on the label before you buy.
Safety first: a drive's DC bus capacitors can hold a dangerous charge after power is removed. Follow your site's lockout/tagout procedure and wait the time given on the drive's label; before anyone touches the terminals, a qualified person verifies zero voltage with a properly rated meter, checking the meter on a known source before and after.
Frequently asked questions
Is the Allen-Bradley PowerFlex 4 / 40 still made?
Mostly not. Of the 72 PowerFlex 4 / 40 catalog numbers on this page, Rockwell Automation's product pages list 53 as Discontinued. Exceptions: 19 catalog numbers are Active. Checked on October 17, 2026; statuses change, so confirm on Rockwell's site before you plan.
What replaces a PowerFlex 4 or PowerFlex 40 drive?
Rockwell's path off the PowerFlex 4 / 40 is PowerFlex 523 (25A) and PowerFlex 525 (25B). Rockwell's product pages name a replacement catalog number for 53 of the 72 PowerFlex 4 and 40 drives on this page – for example, the 22A-V2P3N104 page names the 25A-V2P5N104; the table shows each one. 19 catalog numbers are still Active on Rockwell's pages. Rockwell's PowerFlex 40 to PowerFlex 525 migration guide (publication PFLEX-AP011) compares the two drives.
Which PowerFlex 4 / 40 catalog numbers have a named replacement?
Rockwell's product pages name a replacement catalog number for 53 of the 72 PowerFlex 4 / 40 catalog numbers on this page – for example, the 22A-V2P3N104 page names the 25A-V2P5N104, and the 22A-A1P5N104 page the 25A-A1P6N104. The table lists the named replacement for each; check Rockwell's documentation for fit, wiring and settings before you swap.
Can I still buy PowerFlex 4 / 40 drives?
Not new from Rockwell once a catalog number is discontinued. We stock surplus and used units - the table shows what is in stock right now - and source the ones we don't have: send the catalog numbers through the quote form. Purchase orders are welcome; payment is due before we ship.
