Substitute Part Grouping Explanation

Substitute parts for the AP7315D-12FS4-7B are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Fixed output voltage of 1.2V
• Output current capability of 150mA
• Maximum input voltage of 5.25V
• Dropout voltage specification of 0.64V @ 150mA
• Quiescent current of 60 µA
• PSRR of 75dB (1kHz)
• Operating temperature range of -40°C ~ 85°C
• Package configuration: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Surface mount mounting type
• Over current protection feature
• RoHS3 compliance and MSL 1 rating

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
