FFF CompatibilityThe 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.

  • Official Pb-free/RoHS-compliant drop-in replacement from the original manufacturer
  • Identical physical footprint (16-SOIC) and pin configuration
  • Maintains exact same electrical specifications including 5 Ohm max on-resistance and ±4.5V to ±20V dual supply voltage range

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.

  • Pin-for-pin compatible drop-in replacement from an alternative manufacturer
  • Wider operating temperature range: -40°C to +125°C (vs. -40°C to +85°C for ADG451BR)
  • Very close maximum on-state resistance matching: 5.3 Ohm vs. 5.0 Ohm
  • Narrower dual supply limit: ±15V max compared to the original ±20V max

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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.
