| FFF Compatibility | Standard SO-8 package with exact matching pinout (Pins 1-3: Source, Pin 4: Gate, Pins 5-8: Drain) and no exposed pad.Identical surface-mount SO-8 dimensions, lead style, and footprint layout.Virtually equivalent electrical ratings, but maximum operating junction temperature is slightly lower at 150°C compared to 155°C on the original part. | Standard SO-8 package with exact matching pinout (Pins 1-3: Source, Pin 4: Gate, Pins 5-8: Drain).Identical SO-8 surface-mount dimensions and board land pattern.Excellent electrical compatibility, but has a slightly lower maximum operating temperature of 150°C vs 155°C. | ||
 AI Summary | IRF7821TRPBFXTMA1 by Infineon Technologies: N-Channel 30 V 13.6A (Ta) 2.5W (Ta) Surface Mount PG-DSO-8-902. | This is the official manufacturer-recommended replacement for the obsolete IRF7821. It offers highly similar performance characteristics with an improved, lower RDS(on) and gate charge in an identical SO-8 footprint, making it a perfect drop-in replacement for almost all designs.
| An active second-source N-channel MOSFET from Vishay. It provides lower RDS(on) and higher continuous drain current in the same SO-8 package, serving as an excellent alternative for high-efficiency synchronous buck converter applications.

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 Infineon Technologies IRF7821TRPBFXTMA1 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 Infineon Technologies IRF7821TRPBFXTMA1 are the IRF8714TRPBF (Infineon Technologies) and the SI4162DY-T1-GE3 (Vishay Siliconix), out of 4 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 IRF7821TRPBFXTMA1 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.
