| FFF Compatibility | The pin assignments (Pin 1: Input, Pin 2: Ground, Pin 3: Output) and standard TO-220-3 footprint are identical to the original part.Both utilize the standard through-hole TO-220 physical package with matching physical dimensions.Features identical 5V fixed output, 35V maximum input, and identical 0°C to 125°C operating temperature range. | The pinout (Pin 1: Input, Pin 2: Ground, Pin 3: Output) and standard TO-220 footprint are identical to the original part.Housed in the identical TO-220 physical package and mounting profile.Meets or exceeds all performance specs, extending the lower operating temperature range. | ||
 AI Summary | LM7805ACT by onsemi: Linear Voltage Regulator IC Positive Fixed 1 Output 1.5A TO-220-3. | This is the official direct replacement recommended by onsemi, offering the same high-accuracy ACT grade and electrical characteristics in an identical TO-220 package. It represents the lowest risk migration path from the obsolete part.
| This is a high-reliability sibling from the same manufacturer series, extending the operating temperature down to -40°C while maintaining the high-accuracy output characteristics. It is highly suited for designs facing harsher environmental conditions.

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 LM7805ACT 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 LM7805ACT are the MC7805ACTG (onsemi) and the MC7805ABTG (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 LM7805ACT 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 LM7805ACT (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.
