Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC29152BT are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution compatibility are:

• Output configuration (Positive)
• Output type (Adjustable)
• Package type (TO-220-5)
• Voltage specifications (Input Max: 26V, Output range: 1.25V–25V)
• Current rating (1.5A)
• Voltage dropout (0.6V @ 1.5A)
• Operating temperature range (-40°C ~ 125°C)
• Protection features (Over Current, Over Temperature, Reverse Polarity, Transient Voltage)

The MIC29152WT meets all these electrical and mechanical requirements, establishing it as a direct substitute for the MIC29152BT.

Parameter Comparison

Engineering Selection Recommendations

The MIC29152WT is the direct substitute for the MIC29152BT. Both parts share identical electrical specifications and mechanical packaging. The primary distinction is product status and compliance certification: the MIC29152BT is obsolete, while the MIC29152WT maintains active product status. Additionally, the MIC29152WT carries ROHS3 compliance, whereas the MIC29152BT is RoHS non-compliant. For new designs or ongoing procurement where regulatory compliance is required, the MIC29152WT is the appropriate selection. Both parts are manufactured by Microchip Technology and are functionally interchangeable within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the MIC29152WT directly replace the MIC29152BT in existing designs?

A: Yes. The MIC29152WT is electrically and mechanically equivalent to the MIC29152BT. Both parts feature identical voltage specifications, current ratings, dropout characteristics, protection features, and TO-220-5 packaging. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from MIC29152BT to MIC29152WT?

A: The MIC29152BT is classified as obsolete product status. The MIC29152WT is the active equivalent from Microchip Technology, ensuring continued availability and supply chain support. Additionally, the MIC29152WT meets ROHS3 compliance requirements.

Q: Are there packaging differences between these parts?

A: Both parts use TO-220-5 through-hole packaging. The MIC29152WT is supplied in tube packaging, while the MIC29152BT packaging specification was not provided. The functional package type remains identical.

Q: Do these parts have the same thermal and electrical performance?

A: Yes. Both parts operate across the same temperature range (-40°C to 125°C), deliver 1.5A output current, support 26V maximum input voltage, and provide adjustable output from 1.25V to 25V with 0.6V maximum dropout at full load.

Q: Are there any compliance or certification differences?

A: The MIC29152WT is ROHS3 compliant, while the MIC29152BT is RoHS non-compliant. Both parts are REACH unaffected and classified under ECCN EAR99. For applications requiring RoHS compliance, the MIC29152WT is the appropriate selection.
