| FFF Compatibility | Housed in the identical 2-X1SON / DPY (DFN1006) footprint with completely identical, symmetrical pin assignments.Identical package dimensions of 1.0mm x 0.6mm with a matching profile.Functionally identical in electrical performance, but lacks the AEC-Q101 automotive grade qualification and wettable flanks of the Q1 suffix. | Symmetrical bidirectional 2-pin layout that matches the DPY/DFN1006 land pattern with no layout changes required.Uses the industry-standard SOD-882 (DFN1006) package measuring 1.0mm x 0.6mm.Offers a slightly higher reverse standoff voltage (7V vs. 5.5V) and superior signal integrity with lower capacitance, maintaining AEC-Q101 qualification. | ||
 AI Summary | ESD451WDPYRQ1 by Texas Instruments: 10V (Typ) Clamp 6A (8/20µs) Ipp Tvs Diode Surface Mount 2-X1SON (1x0.6). | This is the non-automotive baseline version of the same series from Texas Instruments. It offers a direct drop-in physical replacement with identical electrical and ESD performance, though it lacks the AEC-Q101 automotive qualification.
| This automotive-qualified TVS diode from Littelfuse serves as an excellent drop-in replacement. It offers a 7V reverse standoff voltage and significantly lower capacitance (0.15pF) for improved signal integrity on ultra-high-speed interfaces.

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 ESD451WDPYRQ1 is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the Texas Instruments ESD451WDPYRQ1 are the ESD451DPYR (Texas Instruments) and the SP3522-01ETG (Littelfuse Inc.), 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 ESD451WDPYRQ1 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.
