| FFF Compatibility | Matches the exact package footprint and 1:1 pin mapping as the obsolete tube-packaged version.Uses the identical 150-mil SOIC-8 (SOT96-1) package dimensions.Identical electrical specs, current consumption, and 400 kHz dual bidirectional I2C buffer performance. | Matches the standard SOIC-8 footprint with NC on Pin 1.Uses the standard 150-mil SOIC-8 package.Provides identical 2-channel bidirectional I2C buffering up to 400 kHz across the 2.3V to 3.6V range. | ||
 AI Summary | PCA9515AD by Texas Instruments: Buffer, ReDriver 2 Channel 400kHz 8-SO. | This is the exact same chip from NXP but delivered in tape-and-reel packaging instead of individual tubes. It serves as a direct, active drop-in replacement with no layout or electrical changes required.
| This is Texas Instruments' direct equivalent of the PCA9515AD in the same SOIC-8 package. It is functionally and physically identical, though currently marked as Not Recommended for New Designs (NRND) by the manufacturer.

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 Texas Instruments PCA9515AD 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 Texas Instruments PCA9515AD are the PCA9515AD,118 (NXP USA Inc.) and the PCA9515ADR (Texas Instruments), out of 4 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 PCA9515AD 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 PCA9515AD (Texas Instruments) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
