| FFF Compatibility | Both parts share the identical 8-SOIC footprint with a matching 1-to-1 pinout assignment.Both parts are packaged in 8-SOIC with identical physical body dimensions.Identical electrical characteristics and performance, differing only by packaging type (Tape & Reel vs Tube). | Matches the standard 8-SOIC land pattern and has an identical 1-to-1 pin configuration.Packaged in standard 8-SOIC (0.154" width) with identical form factor.Matches the target's 12.5V turn-on / 8.3V turn-off UVLO thresholds, 1MHz frequency, and low startup current. | ||
 AI Summary | UCC2808AD-1 by Texas Instruments: Full-Bridge, Half-Bridge, Push-Pull Regulator Output DC-DC Controller IC 8-SOIC. | This is the direct tape-and-reel equivalent of the obsolete tube-packaged part. It uses the exact same silicon and package, ensuring full drop-in compatibility.
| This is an active, highly compatible second-source alternative from Microchip designed specifically to replace the UCCx808-1 series. It operates over the same temperature range and electrical parameters, though it lacks the specific internal CS discharge transistor found in TI's 'A' version.

Frequently asked questions
Yes. The Texas Instruments UCC2808AD-1 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 UCC2808AD-1 are the UCC2808ADTR-1 (Texas Instruments) and the MIC3808YM-TR (Microchip Technology), out of 5 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 UCC2808AD-1 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 UCC2808AD-1 (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.
