Substitute Part Grouping Explanation

Substitute parts for the TPS70248PWPR are determined by strict equivalence across the following critical parameters:

Output voltage configuration (3.3V and 1.5V dual outputs)
Output current ratings (500mA and 250mA per rail)
Maximum input voltage (6V)
Package type (20-PowerTSSOP)
Dropout voltage performance (0.28V @ 500mA)
Control and protection feature set
Operating temperature range (-40°C to 125°C)
Regulatory compliance (ROHS3, REACH Unaffected)

The TPS70148PWPR meets all these criteria and is classified as a parametric equivalent. Both devices share identical electrical specifications, package dimensions, and functional capabilities, making them directly interchangeable in applications requiring dual-output linear regulation.
