Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP7315D-30FS4-7B is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 3V fixed output
• Output current capability: 150mA
• Input voltage maximum rating: 5.25V
• Voltage dropout characteristic: 0.29V @ 150mA
• Package type: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Surface mount configuration
• Operating temperature range: -40°C ~ 85°C
• Protection features: Over Current
• Regulatory compliance: ROHS3 Compliant

The AP7315-30FS4-7B meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package geometry, and compliance certifications, making them directly interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315D-30FS4-7B and AP7315-30FS4-7B are Active product status components from Diodes Incorporated. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance certifications including ROHS3 and REACH Unaffected status. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either component. Direct substitution is permissible without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can AP7315-30FS4-7B replace AP7315D-30FS4-7B in production?
