| FFF Compatibility | The package, pin count, and pin assignments are completely identical.Both parts are housed in a 16-SOIC narrow package with identical physical dimensions.Direct replacement offering matching electrical specifications, logic levels, and switching speeds. | Exhibits the exact same pin layout and pin count as the ADG451BR.Both are standard 16-SOIC narrow packages with fully compatible footprint.Slightly narrower maximum dual-supply voltage range (±15V vs. ±20V) makes it a partial functional replacement if operated above ±15V. | ||
 AI Summary | ADG451BR by Analog Devices: 4 Circuit IC Switch 1:1 5Ohm 16-SOIC. | This is the direct lead-free (RoHS-compliant) replacement for the obsolete ADG451BR, maintaining identical dimensions, pin assignments, and electrical behavior.
| A highly reliable pin-compatible second-source option from Vishay that offers an extended temperature range and faster switching, with only a minor tradeoff in maximum dual-supply voltage.

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 ADG451BR 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 ADG451BR are the ADG451BRZ (Analog Devices Inc.) and the DG451EY-T1-E3 (Vishay Siliconix), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Partly. Some alternatives to the ADG451BR are full fit-, form- and function-compatible drop-ins, while others match on function but differ in package or a key parameter. Check the fit/form/function notes in the table and the datasheet for your application before swapping.
The ADG451BR (Analog Devices) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
