Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7353-30FS4-7 are identified through parametric equivalence. The substitution logic is based on the following critical parameters that must remain identical:

• Output Voltage Configuration: Fixed positive 3V output
• Output Current Capability: 250mA maximum
• Input Voltage Range: Maximum 5.5V
• Dropout Voltage Performance: 0.15V @ 250mA
• Quiescent Current: 27 µA
• Package and Pinout: 4-XDFN Exposed Pad (X2-DFN1010-4 Type B)
• Regulatory Compliance: AEC-Q100 automotive certification, ROHS3 compliance
• Operating Temperature Range: -40°C ~ 85°C

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No electrical redesign or board layout modification is required for substitution.
