Substitute Part Grouping Explanation
The TLE4254EJAXUMA2 qualifies as a parametric equivalent to the TLE4254EJSXUMA1 based on the following criteria:
Electrical parameters are identical across all critical specifications: 70mA output current, 45V maximum input voltage, 0.4V maximum dropout voltage at 70mA, 80 µA quiescent current, and 60dB PSRR at 100Hz. Both devices feature identical control features (Enable) and protection mechanisms (Over Temperature, Reverse Polarity, Short Circuit).
Mechanical compatibility is maintained through identical package specifications: 8-SOIC with 0.154" width and 3.90mm dimensions, with exposed pad configuration.
Environmental and compliance standards are equivalent: both devices operate across -40°C to 150°C, carry automotive grade classification, hold AEC-Q100 qualification, comply with ROHS3, and maintain identical moisture sensitivity levels (MSL 3, 168 Hours).
The primary distinction is product status: TLE4254EJSXUMA1 is marked as not for new designs, while TLE4254EJAXUMA2 maintains active status, making it the recommended selection for ongoing applications.
