MIC29202BU Equivalent & Substitute Parts

Part Overview

The MIC29202BU is a linear voltage regulator IC from Microchip Technology designed for positive adjustable output applications. It delivers 400mA output current with adjustable voltage regulation from 1.24V to 26V, suitable for power management applications requiring low dropout performance and integrated protection features.

The MIC29202BU is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this regulator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC29202BU is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Voltage range (Input Max: 26V; Output Min: 1.24V; Output Max: 26V)
• Current capacity (400mA output)
• Dropout voltage (0.75V @ 400mA)
• Quiescent current (300 µA)
• Operating temperature range (-40°C ~ 125°C)
• Package type (TO-263-5)
• Control and protection features (Enable, Load Dump, Over Current, Reverse Polarity)

The MIC29202WU meets all these criteria and is therefore a direct functional equivalent. Differences exist only in product status and compliance certifications.

Engineering Selection Recommendations

The MIC29202WU is the direct substitute for the MIC29202BU. Both parts are electrically and mechanically identical across all functional parameters. Selection between these parts should be based on the following factors:

• Product Status: The MIC29202BU is obsolete, while the MIC29202WU is active. For new designs or ongoing production, the MIC29202WU ensures continued availability and supply chain support.
• RoHS Compliance: The MIC29202WU is ROHS3 compliant, whereas the MIC29202BU is non-compliant. Applications subject to RoHS regulations require the MIC29202WU.
• Packaging: The MIC29202WU is supplied in tube packaging, while the MIC29202BU packaging is unspecified. Verify packaging requirements for your assembly process.

Frequently Asked Questions (FAQ)

Q: Can the MIC29202WU directly replace the MIC29202BU in existing designs?

A: Yes. The MIC29202WU is electrically and mechanically equivalent to the MIC29202BU. All electrical parameters, output characteristics, protection features, and package specifications are identical. No circuit modifications are required.

Q: What is the difference between MIC29202BU and MIC29202WU?

A: The primary differences are product status and compliance. The MIC29202BU is obsolete and RoHS non-compliant. The MIC29202WU is active and ROHS3 compliant. Functionally, both parts are identical.

Q: Why should I use MIC29202WU instead of MIC29202BU?

A: The MIC29202WU should be used for new designs and ongoing production because it is an active product with guaranteed supply availability. Additionally, if your application or market requires RoHS compliance, the MIC29202WU meets this requirement while the MIC29202BU does not.

Q: Are there any package differences between these parts?

A: Both parts use the TO-263-5 package (TO-263-6, D2PAK with 5 Leads + Tab). The MIC29202WU is supplied in tube packaging. Verify that tube packaging is compatible with your assembly process.

Q: What are the key electrical parameters that define substitution for this regulator?

A: Substitution is determined by matching output configuration (positive), output type (adjustable), voltage range (26V input max, 1.24V to 26V output), current capacity (400mA), dropout voltage (0.75V @ 400mA), quiescent current (300 µA), operating temperature range (-40°C to 125°C), and protection features (Load Dump, Over Current, Reverse Polarity).
