| FFF Compatibility | Identical standard SOT-23 footprint with verified matching pinout assignments (Pin 1: Gate, Pin 2: Source, Pin 3: Drain).Standard SOT-23 package with identical physical dimensions and mounting style.Meets or exceeds all electrical ratings, offering higher current handling and lower on-resistance while maintaining the same 12V breakdown voltage and low threshold gate drive specifications. | Matches standard SOT-23 pinout assignment (Pin 1: Gate, Pin 2: Source, Pin 3: Drain) and footprint.Same SOT-23-3 (TO-236) physical dimensions and surface-mount package.Provides a higher 20V voltage ceiling while fully matching the continuous current and low-threshold gate drive requirements. | ||
 AI Summary | IRLML6401TRPBF by Infineon Technologies: P-Channel 12 V 4.3A (Ta) 1.3W (Ta) Surface Mount Micro3™/SOT-23. | The SI2333CDS-T1-E3 is a high-performance active replacement from Vishay that provides drop-in compatibility. It matches the original's 12V drain-to-source voltage and 1.8V low-voltage gate drive capability while lowering conduction losses with its 35 mOhm on-resistance. Additionally, it offers a robust 7.1A continuous current rating, which easily covers the original 4.3A limit.
| The DMP2045U-7 is an outstanding active alternative from Diodes Incorporated that features a higher 20V breakdown voltage for added safety margin. It delivers the same 4.3A continuous current rating and lower on-resistance of 45 mOhm. It is highly active with vast distributor inventory, eliminating obsolete component risks.
