| FFF Compatibility | The OPA544T is a single-channel device in a 5-lead TO-220 package, whereas the obsolete OPA2544TG3 is a dual-channel device in an 11-lead TO-220 package.Using this alternative requires two separate physical packages on the board, changing the physical footprint completely.It possesses the exact same electrical characteristics, maximum ratings, and amplifier core design on a per-channel basis. | The PA169A is housed in a compact surface-mount PQ package, whereas the original OPA2544TG3 is a through-hole TO-220-11 component.Transitioning from a through-hole TO-220-11 package to a 20mm x 20mm surface-mount package requires a full board layout revision.It meets or vastly exceeds the critical voltage, output current, and dual-channel operational capabilities of the original. | ||
 AI Summary | OPA2544TG3 by Texas Instruments: Standard (General Purpose) Amplifier 2 Circuit TO-220-11. | The OPA544T is the single-channel version of the obsolete OPA2544T, utilizing the exact same monolithic op-amp design. By using two of these active single-channel devices in parallel on a revised layout, you achieve identical electrical performance with a highly reliable and long-term active solution.
| The Apex PA169A is a high-performance, active dual-channel power amplifier that serves as an excellent replacement for obsolete dual power ICs. It significantly improves the voltage handling capabilities up to 200V while comfortably matching the 2A continuous current requirements in a modern surface-mount footprint.

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 OPA2544TG3 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 OPA2544TG3 are the OPA544T (Texas Instruments) and the PA169A (Apex Microtechnology), 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 OPA2544TG3 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 OPA2544TG3 (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
