 AI Summary | TPS3823-33DBVT by Texas Instruments: Supervisor Push-Pull, Totem Pole 1 Channel SOT-23-5. | The TPS3823A-33DBVR is the direct manufacturer-recommended, pin-for-pin replacement for the obsolete TPS3823-33DBVT. It features a wider operating temperature range and enhanced watchdog circuitry that prevents the reset line from latching low if WDI transitions while RESET is asserted. The 'R' suffix denotes a larger tape-and-reel package quantity (3000 vs 250), but the physical part is identical.
| The STM6823SWY6F is a highly reliable second-source alternative from STMicroelectronics that serves as a direct drop-in replacement. It features an identical pinout in a SOT-23-5 package and very close parametric specifications.
