Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOZ3048PI is determined by the following critical parameters:

• Topology & Function: Buck converter with positive adjustable output
• Output Current Rating: 5A minimum requirement
• Package Compatibility: 8-SOIC with exposed pad (same footprint)
• Output Voltage Range: Must accommodate the required output voltage window
• Input Voltage Range: Must support the system input voltage specification
• Synchronous Rectification: Integrated synchronous rectifier for efficiency
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 and REACH compliance maintained

The AOZ6605PI qualifies as a manufacturer-recommended substitute based on these parameters while offering improved specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The AOZ6605PI is the manufacturer-recommended substitute for the obsolete AOZ3048PI. Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility. The AOZ6605PI offers expanded electrical specifications with lower minimum input voltage (4.5V vs. 7.5V), extended output voltage range (0.6V to 15.3V vs. 0.8V to 14.6V), and higher switching frequency (650kHz vs. 500kHz). The identical 8-SOIC package with exposed pad ensures direct footprint compatibility without PCB redesign. Active product status of the AOZ6605PI provides long-term supply chain stability and technical support availability compared to the obsolete AOZ3048PI.

Frequently Asked Questions (FAQ)

Q: Can the AOZ6605PI be used as a direct replacement for the AOZ3048PI?

A: Yes. Both devices share identical package geometry (8-SOIC with exposed pad), output current rating (5A), topology (buck converter), and operating temperature range (-40°C to 85°C). The AOZ6605PI's expanded input and output voltage ranges provide broader application compatibility.

Q: What are the key electrical differences between these parts?

A: The AOZ6605PI supports lower minimum input voltage (4.5V vs. 7.5V), lower minimum output voltage (0.6V vs. 0.8V), higher maximum output voltage (15.3V vs. 14.6V), and higher switching frequency (650kHz vs. 500kHz). These differences expand the AOZ6605PI's application range while maintaining the same current handling capability.

Q: Are there any PCB layout considerations for substitution?

A: No. Both parts use the identical 8-SOIC package with exposed pad. Existing PCB layouts require no modification for component substitution.

Q: What is the product status difference, and why does it matter?

A: The AOZ3048PI is obsolete, indicating discontinued production and limited future availability. The AOZ6605PI is active, ensuring ongoing supply chain access, technical documentation updates, and manufacturer support for the foreseeable future.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AOZ3048PI and AOZ6605PI are ROHS3 compliant and REACH unaffected, with identical MSL ratings of 1 (Unlimited). Regulatory and environmental requirements are maintained across substitution.
