|---|---|---|---|---|
| FFF Compatibility | The ADG509FBRNZ is the direct RoHS-compliant version of the obsolete ADG509FBRN, using the identical 16-SOIC Narrow footprint and pinout.The package shape, size, and mounting style are identical to the original part.This is the exact same silicon and design, offering the same electrical specifications and fault protection. | Pinout and package match the original ADG509FBRN perfectly.Matches the same 16-SOIC Narrow package footprint and dimensions.The MAX309ESE+ lacks the overvoltage fault-protection of the ADG509F series, meaning it cannot handle signals exceeding the supply rails. | ||
ADG509FBRN by Analog Devices: 2 Circuit IC Switch 4:1 270Ohm (Typ) 16-SOIC. | This is the official, direct RoHS-compliant replacement from Analog Devices Inc. It offers identical electrical parameters, physical dimensions, and fault protection, making it a perfect drop-in replacement.
| This industrial temperature grade variant matches the footprint and temperature range of the original part. It provides lower on-resistance and charge injection, but lacks overvoltage fault-protection.

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 ADG509FBRN 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 ADG509FBRN are the ADG509FBRNZ (Analog Devices Inc.) and the MAX309ESE+ (Analog Devices Inc./Maxim Integrated), out of 5 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 ADG509FBRN 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 ADG509FBRN (Analog Devices) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
