| FFF Compatibility | Identical 16-TSSOP package footprint and pin mapping.Same TSSOP-16 package (SOT403-1) with identical dimensions.Identical electrical performance and features as they use the same internal silicon. | Pin-compatible TSSOP-16 layout matching NXP's pinout.Standard TSSOP-16 package with identical physical dimensions.Equivalent electrical ratings, address decoding, and features. | ||
 AI Summary | PCA9546APW,112 by NXP: Translating Switch Interface 16-TSSOP. | This alternative is the exact same silicon and package from NXP as the queried part, but is shipped in tape and reel packaging instead of tubes. Since the original tube-packaged part is obsolete, this serves as an absolute drop-in replacement with zero design modifications required.
| Texas Instruments' PCA9546APWR is a direct second-source industry equivalent in the same TSSOP-16 package. It matches the original's 2.3V to 5.5V supply voltage, I2C logic level behavior, and pin mapping perfectly.

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 NXP PCA9546APW,112 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 NXP PCA9546APW,112 are the PCA9546APW,118 (NXP USA Inc.) and the PCA9546APWR (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 PCA9546APW,112 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 PCA9546APW,112 (NXP) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
