| FFF Compatibility | Identical 8-pin DIP (PDIP) pin assignments verified via datasheet pinout extraction (Outputs on pins 1 & 7, Inputs on pins 2, 3, 5, 6, and Power/GND on pins 8 & 4).Housed in an identical 8-pin standard through-hole plastic dual in-line package (PDIP/8-DIP).Matches all key electrical specifications including the 2.0 V to 36 V supply voltage, 0°C to 70°C commercial temperature range, and 2 mV maximum input offset voltage. | Identical 8-pin DIP pinout assignment and package pitch.Identical standard 8-pin DIP through-hole body dimensions.The standard LM393NG has a slightly higher maximum input offset voltage (5.0 mV vs the 2.0 mV maximum of the 'A' grade LM393AN). | ||
 AI Summary | LM393AN by onsemi: Comparator Standard (General Purpose) 8-DIP. | The LM393AP from Texas Instruments is a highly reliable, active drop-in replacement that perfectly matches the tighter 2mV maximum input offset voltage of the obsolete LM393AN. It operates over the identical supply voltage range of 2V to 36V and the same 0°C to 70°C commercial temperature range. This is the optimal direct second-source alternative for this application.
| The LM393NG is the modern, active, lead-free (Pb-free) standard version from the original manufacturer, onsemi. It shares the exact physical package and pinout, but operates with a slightly relaxed standard input offset voltage rating of 5mV maximum instead of the tighter 2mV of the obsolete LM393AN. For applications that do not require high precision, this is a highly reliable same-brand solution.

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 LM393AN 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 LM393AN are the LM393AP (Texas Instruments) and the LM393NG (onsemi), out of 6 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 LM393AN 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 LM393AN (onsemi) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
