Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOZ3045PI is based on the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 8-SOIC (0.154", 3.90mm Width) Exposed Pad configuration to ensure PCB layout and thermal management compatibility.
• Mounting Type: Surface mount technology must be maintained for manufacturing process consistency.
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved.
• Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures equivalent handling and storage requirements.
• Output Current Capacity: The substitute AOZ6604PI provides 4A output, which exceeds the 3A requirement of the original part, making it functionally compatible for applications designed around the AOZ3045PI.

The AOZ6604PI qualifies as a manufacturer-recommended substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The AOZ6604PI is the manufacturer-recommended substitute for the obsolete AOZ3045PI. Both devices maintain identical package geometry, mounting technology, and regulatory compliance profiles. The AOZ6604PI is currently in active production status, ensuring long-term availability and supply chain stability. The increased output current rating of 4A provides additional design margin for applications originally specified at 3A, with no derating required for existing circuit implementations. Compliance certifications remain equivalent across RoHS3, REACH, and export control classifications.

Frequently Asked Questions (FAQ)

Q: Can the AOZ6604PI be used as a direct replacement for the AOZ3045PI?

A: Yes. Both devices share identical package specifications (8-SOIC with Exposed Pad), mounting type (Surface Mount), and regulatory compliance status. The AOZ6604PI's higher 4A output rating is compatible with applications designed for the 3A AOZ3045PI.

Q: Are there any PCB layout modifications required when substituting the AOZ6604PI for the AOZ3045PI?

A: No PCB layout modifications are required. Both parts use the same 8-SOIC (0.154", 3.90mm Width) Exposed Pad package, ensuring pin-for-pin compatibility and identical thermal pad dimensions.

Q: What is the significance of the AOZ3045PI being classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured. The AOZ6604PI, with active production status, provides a supported alternative for new designs and production continuity.

Q: Do moisture sensitivity and handling requirements differ between these parts?

A: No. Both the AOZ3045PI and AOZ6604PI carry an MSL rating of 1 (Unlimited), requiring identical storage and handling procedures.

Q: Are regulatory certifications maintained with the AOZ6604PI substitute?

A: Yes. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring equivalent regulatory standing.
