|---|---|---|---|---|
| FFF Compatibility | The package is identical (28-HTSSOP with thermal pad), but Pin 2 (VSENSE) requires an external resistor feedback divider on the TPS54610, whereas the TPS54615 uses a direct connection to the output. Additionally, Pin 27 acts as a synchronization (SYNC) pin rather than a frequency select (FSEL) pin.The package and absolute dimensions (28-PowerTSSOP / HTSSOP-28) are fully identical and compatible.All key electrical characteristics, including the 3V-6V input range, 6A output current capability, and -40°C to 125°C temperature range are fully met or exceeded. | Requires a board redesign due to a smaller 16-PowerTSSOP package instead of the original 28-PowerTSSOP.The physical dimensions and lead footprint are completely different.Meets or exceeds all critical electrical constraints, providing up to 6A output from a 2.95V to 5.5V input rail. | ||
 AI Summary | TPS54615PWPRG4 by Texas Instruments: Buck Switching Regulator IC Positive Fixed 2.5V 1 Output 6A 28-PowerTSSOP (0.173", 4.40mm Width). | The TPS54610PWPR is the adjustable-output counterpart from the same SWIFT™ family, representing the closest active replacement. It features the same physical footprint and electrical ratings but requires modifying the board layout to include a feedback resistor divider at Pin 2 (VSENSE) to program the 2.5V output, as well as checking Pin 27 (SYNC vs FSEL).
| The LM20136MH/NOPB is an active, modern 6A synchronous buck regulator from Texas Instruments optimized for low-voltage rails. It provides identical output current capability and matches the low-voltage operating conditions, but requires a layout redesign to accommodate its smaller 16-PowerTSSOP package.

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 TPS54615PWPRG4 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 TPS54615PWPRG4 are the TPS54610PWPR (Texas Instruments) and the LM20136MH/NOPB (Texas Instruments), out of 3 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 TPS54615PWPRG4 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 TPS54615PWPRG4 (Texas Instruments) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
