Substitute Part Grouping Explanation

Substitution of the MAX253CUA-T is based on the following criteria derived from the provided parameters:

Primary Substitution Basis:

• Identical base product number (MAX253)
• Shared manufacturer (Analog Devices Inc./Maxim Integrated)
• Equivalent functional classification (Power Management PMIC)
• Active product status with current availability

Allowed Substitution Parameters:

• Supply voltage compatibility (3.3V, 5V operation)
• Supply current specifications (450µA)
• Operating temperature range (0°C ~ 70°C)
• Surface mount mounting type
• Package family compatibility (8-pin TSSOP/MSOP/uMAX variants)
• RoHS3 compliance maintained

The MAX253CUA+T qualifies as a direct substitute based on these parameters while offering improved moisture sensitivity characteristics and active product status.
