 AI Summary | ADUM1400ARW by Analog Devices: General Purpose Digital Isolator 2500Vrms 4 Channel 1Mbps 25kV/µs CMTI 16-SOIC (0.295", 7.50mm Width). | This is the direct, RoHS-compliant lead-free replacement designated by the manufacturer. It offers identical electrical parameters, timing characteristics, and physical dimensions, allowing for a seamless drop-in replacement with no design changes.
| This is a newer generation upgrade from Analog Devices that serves as an excellent active alternative. It retains full pin compatibility while providing vastly superior speed, higher isolation voltage, better noise immunity (CMTI), and support for lower voltage supplies.

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 ADUM1400ARW 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 ADUM1400ARW are the ADUM1400ARWZ (Analog Devices Inc.) and the ADUM140E0BRWZ (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 ADUM1400ARW 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 ADUM1400ARW (Analog Devices) is a part in the Digital Isolators category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
