Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP7315D-32FS4-7B is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 3.2V fixed output
• Output current capability: 150mA
• Input voltage maximum rating: 5.25V
• Voltage dropout characteristic: 0.29V @ 150mA
• Package configuration: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Mounting technology: Surface Mount
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: RoHS3 Compliant

The AP7315-32FS4-7B qualifies as a parametric equivalent substitute based on identical electrical specifications, package type, and compliance certifications across all measured parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315D-32FS4-7B and AP7315-32FS4-7B are Active products from Diodes Incorporated with identical electrical and mechanical specifications.
