| FFF Compatibility | Requires PCB layout changes due to pin count and package type differences (16-SOIC vs 16-TSSOP).The SOIC-16 package has a different footprint size and lead pitch compared to the original TSSOP-16.Matches the core voltage-mode active-clamp controller features and operates as a direct functional equivalent. | Requires layout changes due to different pin configuration and count (20-TSSOP vs 16-TSSOP).The 20-TSSOP package has a larger physical footprint than the original 16-TSSOP package.Operates in current-mode instead of voltage-mode, requiring modifications to the feedback loop and compensation components. | ||
 AI Summary | LM5025AMTC/NOPB by Texas Instruments: Forward Converter Regulator Positive, Isolation Capable Output Step-Up/Step-Down DC-DC Controller IC 16-TSSOP. | The NCP1562BDR2G by onsemi is a highly suitable functional replacement because it implements the same voltage-mode active-clamp forward converter control as the obsolete TI LM5025A. It features similar programmable overlap delay, soft-start, and synchronization capabilities in an active lifecycle device. However, it requires a PCB redesign to accommodate the 16-SOIC package footprint.
| The UCC2897APWR is an active-lifecycle alternative from Texas Instruments that implements the active-clamp forward topology. While it is a current-mode controller rather than voltage-mode, it offers excellent performance and synchronous rectification features, though it requires modifications to the feedback compensation loop and PCB layout.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Texas Instruments LM5025AMTC/NOPB is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Texas Instruments LM5025AMTC/NOPB are the NCP1562BDR2G (onsemi) and the UCC2897APWR (Texas Instruments), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the LM5025AMTC/NOPB are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The LM5025AMTC/NOPB (Texas Instruments) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
