Substitute Part Grouping Explanation

Substitute parts for the AP7315D-28FS4-7B are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Fixed output voltage of 2.8V
• Output current rating of 150mA
• Maximum input voltage of 5.25V
• Voltage dropout specification of 0.29V @ 150mA
• 4-XDFN Exposed Pad package configuration
• Surface Mount mounting type
• Operating temperature range of -40°C ~ 85°C
• Active product status
• RoHS3 compliance and REACH Unaffected status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status from Diodes Incorporated and carry identical RoHS3 compliance and REACH Unaffected certifications. Selection between AP7315D-28FS4-7B and AP7315-28FS4-7B is based on availability and supply chain requirements, as all electrical and mechanical specifications are equivalent. Both parts are suitable for applications requiring a 2.8V fixed output linear regulator with 150mA capacity in Surface Mount 4-XDFN packaging.

Frequently Asked Questions (FAQ)

Q: Can AP7315-28FS4-7B replace AP7315D-28FS4-7B in existing designs?

A: Yes. Both parts are parametric equivalents with identical output voltage, current rating, package type, and operating specifications. Direct substitution is supported without circuit modification.

Q: Are there any package compatibility differences between these parts?

A: No. Both parts use the 4-XDFN Exposed Pad package with identical pinout and thermal characteristics. PCB layout and footprints are interchangeable.

Q: What is the significance of the "D" designation in AP7315D-28FS4-7B?

A: The "D" is part of the manufacturer's internal part numbering scheme. The electrical and mechanical specifications remain identical to the AP7315-28FS4-7B variant.

Q: Are both parts RoHS compliant?

A: Yes. Both AP7315D-28FS4-7B and AP7315-28FS4-7B are ROHS3 Compliant with MSL Rating 1 (Unlimited moisture sensitivity level).

Q: What is the maximum input voltage for these regulators?

A: The maximum input voltage is 5.25V for both parts. Operating above this specification may damage the device.

Q: What is the dropout voltage at full load?

A: The voltage dropout is 0.29V at 150mA output current for both parts, enabling operation with input voltages as low as 3.09V for the 2.8V output specification.
