Substitute Part Grouping Explanation

The AP7315-295FS4-7B has one parametric equivalent substitute: AP7315D-295FS4-7B. This substitute relationship is established based on identical electrical and mechanical specifications across all critical parameters that determine functional interchangeability:

• Fixed output voltage: 2.95V
• Output current capacity: 150mA
• Maximum input voltage: 5.25V
• Voltage dropout: 0.29V @ 150mA
• Quiescent current: 60 µA
• PSRR performance: 75dB (1kHz)
• Package configuration: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Operating temperature range: -40°C ~ 85°C
• Protection features: Over Current
• Compliance certifications: ROHS3, REACH Unaffected

Both parts share the same base product number (AP7315) and are manufactured by Diodes Incorporated. The substitution is valid for direct replacement in circuit designs where the AP7315-295FS4-7B is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7315-295FS4-7B and AP7315D-295FS4-7B are active production components manufactured by Diodes Incorporated with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and procurement lead times. The AP7315-295FS4-7B currently has higher stock availability (1154 units) compared to the AP7315D-295FS4-7B (1032 units). Both parts meet identical electrical performance specifications and are suitable for direct substitution in applications requiring a 2.95V, 150mA linear voltage regulator in the 4-XDFN package.

Frequently Asked Questions (FAQ)

Q: Can AP7315D-295FS4-7B be used as a direct replacement for AP7315-295FS4-7B?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current capacity, dropout voltage, and package configuration. Direct substitution is valid for circuit designs.
