Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOZ1022PI is determined by the following critical parameters:

• Topology & Function: Buck switching regulator with positive adjustable output
• Package Compatibility: 8-SOIC with exposed pad (0.154", 3.90mm Width)
• Electrical Specifications: Input voltage range, output voltage range, output current capacity, and switching frequency
• Synchronous Rectification: Presence of integrated synchronous rectifier
• Mounting Type: Surface mount configuration

The MP8715DN-LF qualifies as a substitute based on matching topology, package form factor, and core electrical parameters. Differences in maximum ratings and operating temperature ranges are noted in the parameter comparison.

Parameter Comparison

Engineering Selection Recommendations

The MP8715DN-LF is an active product from Monolithic Power Systems Inc. and serves as a functional substitute for the obsolete AOZ1022PI. Both devices share identical package geometry, topology, and core switching frequency, enabling direct replacement in existing PCB layouts.

The MP8715DN-LF offers enhanced specifications: higher maximum input voltage (21V vs. 18V), higher maximum output voltage (21V vs. 18V), increased output current capacity (4A vs. 3A), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). These improvements provide additional design margin and operational flexibility.

Both parts maintain ROHS3 compliance and REACH unaffected status. The MSL rating difference (1 vs. 2A) reflects standard moisture sensitivity classifications and should be considered in storage and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the MP8715DN-LF directly replace the AOZ1022PI on existing PCBs?

A: Yes. Both devices use identical 8-SOIC package geometry with exposed pad and matching pinout compatibility for buck regulator topologies. PCB layout and footprints designed for the AOZ1022PI are compatible with the MP8715DN-LF.

Q: What are the key differences between these parts?

A: The MP8715DN-LF provides higher maximum voltage ratings (21V input/output vs. 18V), greater output current capacity (4A vs. 3A), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). The AOZ1022PI has lower moisture sensitivity (MSL 1 vs. MSL 2A).

Q: Is the MP8715DN-LF suitable for applications originally designed for the AOZ1022PI?

A: The MP8715DN-LF is suitable for applications within the AOZ1022PI's original specifications. The higher ratings of the MP8715DN-LF do not create incompatibility; however, circuit design parameters such as feedback resistor networks and output capacitor selection should be verified against the MP8715DN-LF datasheet to ensure proper operation.

Q: What compliance certifications apply to both parts?

A: Both the AOZ1022PI and MP8715DN-LF are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and HTSUS code 8542.39.0001.

Q: How should moisture sensitivity differences be handled?

A: The AOZ1022PI (MSL 1) has unlimited shelf life under controlled conditions. The MP8715DN-LF (MSL 2A) requires storage at controlled humidity for up to 4 weeks. Verify component storage conditions and reflow procedures according to the respective manufacturer's handling guidelines.
