Substitute Part Grouping Explanation

Substitution eligibility for the TLE4274GSV33HTSA2 is determined by strict parametric matching across the following critical criteria:

Output Specifications: Fixed 3.3V output voltage and 400mA output current capacity must be identical.

Electrical Performance: Input voltage rating (40V max), dropout voltage (1.2V @ 300mA), quiescent current (220 µA), and PSRR (60dB @ 100Hz) must match exactly.

Protection & Features: Over-current, over-temperature, reverse polarity, and short-circuit protection must be present.

Package & Mounting: PG-SOT223-4 package with surface-mount technology is mandatory for mechanical and thermal compatibility.

Compliance & Grade: Automotive grade with AEC-Q100 qualification and ROHS3 compliance are required for equivalent substitution.

The TLE4274GSV33HTMA1 meets all these criteria as a parametric equivalent from the same manufacturer base product family (TLE4274).
