| FFF Compatibility | Both devices share the identical TSSOP-8 (PW-8) footprint and pin assignment.Both devices use the exact same TSSOP-8 package with 3.00 mm x 4.40 mm nominal body size.Shares identical electrical performance parameters, with the added benefit of a wider industrial operating temperature range. | Uses a 5-pin SOT-23 (SOT-753) package instead of the 8-pin TSSOP, requiring a PCB layout redesign.Much smaller package footprint and different physical shape.Provides superior ESD clamping and power handling compared to the obsolete part while maintaining safe voltage levels for 3.3V/5V USB lines. | ||
 AI Summary | SN75240PWR by Texas Instruments: Mixed Technology TVS Device 1 Circuit 7V Surface Mount 8-TSSOP. | The SN65240PWR is the direct, manufacturer-recommended replacement for the obsolete SN75240PWR, offering the exact same physical package, pinout, and electrical characteristics but with an upgraded industrial temperature rating.
| A modern, highly robust 4-channel TVS diode array designed for USB lines, offering much stronger surge performance and lower clamping voltage in a compact SOT-23-5 package.

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 SN75240PWR 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 SN75240PWR are the SN65240PWR (Texas Instruments) and the ESDS314DBVR (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 SN75240PWR 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 SN75240PWR (Texas Instruments) is a part in the Transient Voltage Suppressors (TVS) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
