| FFF Compatibility | Standard 8-SOIC footprint with identical pinout and pin assignments.Matches the physical package (8-SOIC) and dimensions of the original part.Identical electrical performance and ratings, including the 2mV max offset voltage and -25°C to 85°C operating range. | Standard 8-SOIC footprint with identical pin assignments.Matches the standard SO-8 (SOIC-8) package dimensions.Meets or exceeds all electrical parameters, including supply voltage limits, output drive, and temperature ratings. | ||
 AI Summary | LM293AD by Texas Instruments: Comparator Standard (General Purpose) Open-Collector, Open-Drain, Rail-to-Rail 8-SOIC. | The LM293ADR is the direct packaging variant (Tape & Reel instead of Tube) of the obsolete LM293AD. It uses the exact same silicon and package, making it a 100% compatible drop-in replacement with no tradeoffs.
| The LM293ADT is a high-reliability second-source option from STMicroelectronics. It matches the high-accuracy 2mV offset voltage rating of the original part while expanding the operating temperature range down to -40°C.

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 LM293AD 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 LM293AD are the LM293ADR (Texas Instruments) and the LM293ADT (STMicroelectronics), out of 3 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 LM293AD 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 LM293AD (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
