MIC29752BWT Equivalent & Substitute Parts

Part Overview

The MIC29752BWT is a linear voltage regulator IC from Microchip Technology designed for positive adjustable output applications. It delivers 7.5A output current in a TO-247-5 package and supports input voltages up to 26V with adjustable output ranging from 1.25V to 25V. The device includes integrated protection features for over-current, over-temperature, reverse polarity, and transient voltage conditions.

The MIC29752BWT is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC29752BWT is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Maximum input voltage (26V)
• Output voltage range (1.25V to 25V)
• Output current rating (7.5A)
• Voltage dropout specification (0.75V @ 7.5A)
• Package type (TO-247-5)
• Control features (Enable)
• Protection features (Over Current, Over Temperature, Reverse Polarity, Transient Voltage)
• Operating temperature range (-40°C ~ 125°C)
• Mounting type (Through Hole)

The MIC29752WWT meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications and mechanical compatibility, with differences limited to product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MIC29752WWT is the direct substitute for the MIC29752BWT. Both parts are electrically and mechanically identical across all specified parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MIC29752BWT is obsolete, while the MIC29752WWT maintains active product status. The MIC29752WWT also carries ROHS3 compliance certification, whereas the MIC29752BWT is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs or applications requiring regulatory compliance with modern standards, the MIC29752WWT is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part meets the electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can MIC29752WWT replace MIC29752BWT in existing designs?

A: Yes. The MIC29752WWT is electrically and mechanically equivalent to the MIC29752BWT. Both parts deliver identical performance across all specified electrical parameters, including output current, voltage range, dropout voltage, and protection features. The TO-247-5 package is identical, ensuring direct PCB compatibility without layout modifications.

Q: What is the difference between MIC29752BWT and MIC29752WWT?

A: The parts are functionally identical. Differences exist only in product status and compliance certifications. The MIC29752BWT is obsolete and RoHS non-compliant. The MIC29752WWT is an active product with ROHS3 compliance. Both maintain identical electrical specifications and package configurations.

Q: Is the TO-247-5 package the same for both parts?

A: Yes. Both the MIC29752BWT and MIC29752WWT use the TO-247-5 package. This is a through-hole mounted package with identical pinout, mechanical dimensions, and thermal characteristics. No PCB redesign is required when substituting between these parts.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and manufacturing processes, not electrical performance. Both the RoHS non-compliant MIC29752BWT and ROHS3 compliant MIC29752WWT deliver identical electrical specifications and performance characteristics.

Q: Are there inventory considerations when selecting between these parts?

A: Yes. The MIC29752BWT is classified as obsolete with 4322 pieces in stock. The MIC29752WWT is an active product with 5882 pieces available in tube packaging. For long-term supply chain reliability, the MIC29752WWT is the preferred selection.
