| FFF Compatibility | Shares the identical TO-220 package, pin configuration, and mounting pitch.Identical TO-220 case dimensions and mounting-hole alignment.Matches all critical parameters, including 5V output, 1A current capacity, and 35V maximum input voltage. | Directly mounts to the same footprint with the identical TO-220 pin assignments.Perfectly matches the mechanical outline of the standard TO-220 package.Meets or exceeds all original parameters, offering an upgraded accuracy grade. | ||
 AI Summary | MC7805CT by onsemi: Linear Voltage Regulator IC Positive Fixed 1 Output 1A TO-220. | The MC7805CTG is the direct RoHS-compliant replacement for the obsolete MC7805CT. It maintains the identical electrical, thermal, and mechanical characteristics while transitioning to lead-free construction. This is the highest-confidence drop-in choice for existing designs.
| The MC7805ACTG is a high-accuracy drop-in alternative from the same onsemi family. It upgrades the output voltage accuracy from the standard 4% to a tighter 2%, making it highly compatible and structurally superior for precision 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 onsemi MC7805CT 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 onsemi MC7805CT are the MC7805CTG (onsemi) and the MC7805ACTG (onsemi), 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 MC7805CT 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 MC7805CT (onsemi) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
