| FFF Compatibility | The physical footprint is identical and pinout is functionally equivalent, but the datasheet utilizes different pin naming labels (e.g., 'GND' vs 'Vcc-').Both parts use the standard 8-pin SOIC surface-mount package with equivalent mechanical dimensions.The electrical characteristics, including input offset voltage, supply range, and current limits, match the obsolete target part. | Pin assignments are functionally identical, but the datasheet names pins differently (e.g., 'Out1' vs '1OUT', 'Vcc-' vs 'GND').Both utilize the industry standard SOIC-8 (SO8) surface-mount package.All key electrical specifications, including the 5mV maximum input offset voltage, meet or exceed the original TI part. | ||
 AI Summary | LM293D by Texas Instruments: Comparator Standard (General Purpose) Open-Collector, Open-Drain, Rail-to-Rail 8-SOIC. | The LM293DR is the direct active equivalent from Texas Instruments, offering the identical dual comparator circuit in the same SOIC-8 package. This part is a highly active, long-lived line that serves as the perfect replacement for the obsolete LM293D, with the only difference being its tape-and-reel distribution packaging instead of tube.
| The LM293DT from STMicroelectronics is an outstanding second-source alternative that is highly active and widely stocked. It provides a significant thermal upgrade by supporting operating temperatures down to -40°C and up to +105°C, making it highly reliable in more demanding environments.

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 LM293D 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 LM293D are the LM293DR (Texas Instruments) and the LM293DT (STMicroelectronics), 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 LM293D 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 LM293D (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
