Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7387-33FDC-7 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:

Electrical Parameters (Must Match):

• Output voltage: 3.3V fixed
• Output current capability: 150mA
• Input voltage maximum: 60V
• Dropout voltage: 1.35V @ 150mA
• Quiescent current: 4 µA
• PSRR: 70dB (1kHz)

Mechanical & Packaging Parameters (Must Match):

• Package type: 6-UDFN Exposed Pad (U-DFN2020-6 Type C)
• Mounting type: Surface Mount

Compliance & Qualification (Must Match):

• Automotive grade
• AEC-Q100 qualification
• RoHS3 compliance
• MSL Level 1

Only parts meeting all these criteria are classified as direct substitutes. Packaging differences, output voltage variations, or lower current ratings disqualify parts from substitution eligibility.
