| FFF Compatibility | Standard SO-8 package with identical pin assignments (Pins 1-3: Source, Pin 4: Gate, Pins 5-8: Drain).Same surface-mount SO-8 / SOIC-8 package footprint and dimensions.Meets the 30V Vdss, +/-20V Vgs, and 13.6A continuous current ratings while delivering slightly lower on-resistance. | Standard SO-8 package with identical pin assignments (Pins 1-3: Source, Pin 4: Gate, Pins 5-8: Drain).Same standard SOIC-8 surface mount package layout.Vdss of 30V matches, with a higher continuous current rating and equivalent gate drive characteristics. | ||
 AI Summary | IRF7821PBF by Infineon Technologies: N-Channel 30 V 13.6A (Ta) 2.5W (Ta) Surface Mount 8-SO. | The SI4162DY-T1-GE3 from Vishay is an active, high-performance drop-in replacement that matches the original part's key voltage and continuous current ratings. It features a lower maximum on-resistance of 7.9 mOhm, which will reduce conduction losses. This makes it an ideal second-source alternative for obsolete IRF7821PBF designs.
| The DMN3010LSS-13 is an active and robust N-channel alternative offering an elevated current ceiling of 16 A and a slightly improved maximum on-resistance of 9 mOhm. It is highly suited for power management circuits requiring a direct, active-lifecycle replacement.

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 IRF7821PBF 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 IRF7821PBF are the SI4162DY-T1-GE3 (Vishay Siliconix) and the DMN3010LSS-13 (Diodes Incorporated), 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 IRF7821PBF 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 IRF7821PBF (Infineon Technologies) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
