TPS22919DCKR is a 1.5A, 5.5V load switch from Texas Instruments in a compact SC-70 package. Finding a direct drop-in replacement is challenging due to its specific combination of performance and package.

AI replacement insight

Package riskhigh

No drop-in package with matching specs found; redesign is likely required.

Electrical riskmedium

Alternatives often have different input voltage and temperature ranges.

Can it be replaced directly?

There are no known direct, 1-to-1 replacements. The only part in the same package, TPS22948DCKR, is a significant electrical downgrade.

Best replacement path

Redesign the PCB for a functional alternative like AP22804AW5-7, which offers superior current handling and lower on-resistance.

Main risk

The primary risk is the lack of a pin-compatible alternative with equivalent electrical specifications, forcing a PCB redesign for most viable substitutes.
