Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC39150-1.65BU TR is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 1.65V fixed
• Output current capability: 1.5A
• Maximum input voltage: 16V
• Dropout voltage performance: 0.5V @ 1.5A
• Package configuration: TO-263-3 (D2PAK)
• Protection features: Over Current, Over Temperature, Reverse Polarity
• Operating temperature range: -40°C ~ 125°C
• Mounting type: Surface Mount

The MIC39150-1.65WU-TR meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC39150-1.65WU-TR is the direct substitute for the obsolete MIC39150-1.65BU TR. Both parts are manufactured by Microchip Technology and provide identical electrical and mechanical specifications across all critical parameters.

The MIC39150-1.65WU-TR offers the advantage of Active product status, ensuring continued manufacturer support and availability. Additionally, this substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulatory requirements or environmental compliance mandates, the MIC39150-1.65WU-TR is the appropriate selection.

Both parts share identical moisture sensitivity levels (MSL 3, 168 Hours) and REACH status, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the MIC39150-1.65WU-TR be used as a direct replacement for the MIC39150-1.65BU TR?

A: Yes. Both parts deliver identical electrical performance: 1.65V fixed output, 1.5A output current, 0.5V maximum dropout voltage at rated current, and -40°C to 125°C operating temperature range. The TO-263-3 package configuration is identical, enabling direct PCB compatibility without layout modifications.

Q: What is the primary difference between these two parts?

A: The MIC39150-1.65BU TR is Obsolete, while the MIC39150-1.65WU-TR is Active. The substitute part also achieves ROHS3 compliance, whereas the original is RoHS non-compliant. All electrical and mechanical specifications remain equivalent.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts carry identical MSL (Moisture Sensitivity Level) ratings of 3 (168 Hours), requiring the same moisture control and storage protocols during manufacturing and assembly.

Q: Is the TO-263-3 package suitable for my application?

A: The TO-263-3 package (D2PAK with 3 leads plus tab) is a Surface Mount configuration designed for direct soldering to PCB pads. Verify that your PCB layout accommodates this package footprint and that your assembly process supports Surface Mount technology.

Q: What protection features are included in this regulator?

A: Both the original and substitute parts include Over Current, Over Temperature, and Reverse Polarity protection, ensuring robust operation across specified input voltage and temperature ranges.
