Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOZ1044PI is based on the following critical parameters that must remain consistent:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) Exposed Pad (8-SO-EP)
• Mounting Type: Surface Mount
• Function: Step-Down (Buck Regulator)
• Category: Power Management (PMIC)
• Compliance: ROHS3 Compliant, REACH Unaffected

The AOZ6604PI qualifies as a manufacturer-recommended substitute because it maintains identical packaging, mounting configuration, functional topology, and regulatory compliance status. Both devices operate within the same form factor and regulatory framework, enabling direct substitution in applications where the AOZ1044PI was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The AOZ6604PI is the manufacturer-recommended substitute for the obsolete AOZ1044PI. Selection of the AOZ6604PI is supported by the following factors:

• Product Status: The AOZ6604PI maintains Active status, ensuring continued availability and manufacturing support, whereas the AOZ1044PI is Obsolete.
• Regulatory Compliance: Both devices maintain ROHS3 Compliance and REACH Unaffected status, satisfying equivalent environmental and regulatory requirements.
• Package Compatibility: Identical 8-SOIC (0.154", 3.90mm Width) Exposed Pad packaging enables direct PCB layout compatibility without redesign.
• Functional Equivalence: Both devices operate as Buck Switching Regulators within the Power Management (PMIC) category, maintaining functional topology consistency.

Frequently Asked Questions (FAQ)

Q: Can the AOZ6604PI be used as a direct replacement for the AOZ1044PI?

A: Yes. The AOZ6604PI is the manufacturer-recommended substitute. Both devices share identical packaging (8-SOIC with Exposed Pad), mounting type (Surface Mount), functional topology (Buck Step-Down), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).
