| FFF Compatibility | The pin assignments and 28-lead SOIC package layout are identical to the original AD1674KR.Both parts use the exact same wide 28-lead SOIC surface mount body.All electrical performance, timing, and accuracy parameters are identical. This is the official lead-free update. | Utilizes the identical 28-lead SOIC package and pin mapping.Identical package dimensions and mounting footprint.The J-grade suffix features a slightly lower accuracy profile, with an Integral Non-Linearity (INL) of ±1 LSB compared to ±1/2 LSB for the K-grade. | ||
 AI Summary | AD1674KR by Analog Devices: 12 Bit Analog to Digital Converter 1 Input 1 SAR 28-SOIC. | The AD1674KRZ is the direct lead-free (RoHS compliant) equivalent to the obsolete AD1674KR, sharing the exact same specifications, temperature range, and performance. This is the highest confidence, active drop-in replacement available.
| The AD1674JRZ is a parametric equivalent from the same family. It represents the J-grade version, which offers the same 100 kSPS conversion speed but trades off slightly looser accuracy tolerances at a lower price point.

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 Analog Devices AD1674KR 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 Analog Devices AD1674KR are the AD1674KRZ (Analog Devices Inc.) and the AD1674JRZ (Analog Devices Inc.), 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 AD1674KR 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 AD1674KR (Analog Devices) is a part in the Data Acquisition category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
