| FFF Compatibility | Matches the exact TO-220-7 formed-leads footprint and pin configuration of the OPA548TG3.Identical physical dimensions, package style, and mounting style.Identical electrical specs, including 5A continuous output current, 60V maximum supply voltage, and thermal/current limits. | Uses straight pins (KC package code) instead of formed pins, which may require a different lead-bending preparation or slightly different PCB lead spacing depending on target installation.Identical body dimensions but straight leads instead of formed/staggered leads.Identical electrical parameters including 5A output current, 60V max span, and 1 MHz bandwidth. | ||
 AI Summary | OPA548TG3 by Texas Instruments: Power Amplifier 1 Circuit TO-220-7. | The OPA548T is the active, direct replacement for the obsolete green-labeled OPA548TG3, carrying the exact same internal silicon, electrical specifications, and physical package configuration. It represents the lowest-risk path for substitution.
| The OPA548T-1 is an active sibling variant that offers the exact same electrical performance and silicon in a straight-lead TO-220-7 package rather than a formed-lead package. This is a very close alternative if the production line can accommodate or manually bend straight leads.

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 Texas Instruments OPA548TG3 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 OPA548TG3 are the OPA548T (Texas Instruments) and the OPA548T-1 (Texas Instruments), 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 OPA548TG3 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 OPA548TG3 (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
