| FFF Compatibility | Pin configuration and pin assignments match the ADM1023 on every pin.The package is an identical 16-pin QSOP (0.154-inch width) with the exact same physical footprint.It has a lower resolution (1°C/8-bit vs. 0.125°C/11-bit) and a lower remote sensor accuracy (±3°C vs. ±1°C). | All 16 pins align perfectly with the ADM1023 pinout.Housed in the identical 16-QSOP package with matching mechanical dimensions.Resolution is limited to 1°C (8-bit) and remote accuracy is lower (±3°C vs. ±1°C). | ||
 AI Summary | ADM1023ARQZ-REEL by onsemi: Temp Monitoring System (Sensor) 0°C ~ 120°C, External Sensor Internal and External Sensor SMBus Output 16-QSOP. | The MAX1617AMEE+ is the ideal direct replacement for the obsolete ADM1023ARQZ-REEL. It is fully pin-compatible, shares the same 16-QSOP footprint, and offers improved SMBus timing specifications and collision immunity. However, it operates with lower resolution and accuracy compared to the high-precision ADM1023.
| The MAX1617MEE+ is the standard base version of the 1617 series and acts as a direct drop-in second source. It shares the identical pin configuration and QSOP-16 package, though it lacks the advanced timing improvements and manufacturer ID registers of the 'A' version.

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 ADM1023ARQZ-REEL 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 ADM1023ARQZ-REEL are the MAX1617AMEE+ (Analog Devices Inc./Maxim Integrated) and the MAX1617MEE+ (Analog Devices Inc./Maxim Integrated), 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 ADM1023ARQZ-REEL 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 ADM1023ARQZ-REEL (onsemi) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
