Substitute Part Grouping Explanation

Substitution for the MIC29201-4.8BT is determined by strict equivalence across the following electrical and mechanical parameters:

• Output voltage specification: 4.85V fixed
• Output current capability: 400mA minimum
• Input voltage rating: 26V maximum
• Dropout voltage: 0.75V @ 400mA
• Package type: TO-220-5
• Mounting configuration: Through hole
• Control features: Enable function
• Protection features: Load Dump, Over Current, Reverse Polarity

The MIC29201-4.8WT qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC29201-4.8WT is the direct functional equivalent of the MIC29201-4.8BT. Both parts share identical electrical performance specifications and physical packaging. Selection between these parts should be based on:

• Product status: The MIC29201-4.8WT is active and currently supported by the manufacturer, whereas the MIC29201-4.8BT is obsolete.
• Regulatory compliance: The MIC29201-4.8WT meets ROHS3 compliance requirements, while the MIC29201-4.8BT does not.
• Supply continuity: The MIC29201-4.8WT provides assured long-term availability and manufacturing support.

For new designs or production requiring regulatory compliance, the MIC29201-4.8WT is the appropriate selection. For legacy system maintenance where the original part is specified, the MIC29201-4.8WT provides electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MIC29201-4.8WT be used as a direct replacement for the MIC29201-4.8BT?

A: Yes. Both parts deliver identical electrical performance: 4.85V fixed output, 400mA output current, 0.75V dropout voltage, and operate across -40°C to 125°C. Both use TO-220-5 through-hole packaging. The MIC29201-4.8WT is the active production equivalent.

Q: What is the difference between the MIC29201-4.8BT and MIC29201-4.8WT?

A: The primary differences are product status and compliance. The MIC29201-4.8BT is obsolete and RoHS non-compliant. The MIC29201-4.8WT is active production and ROHS3 compliant. Electrical specifications and package type are identical.

Q: Are there packaging differences between these parts?

A: The MIC29201-4.8BT is supplied in bulk packaging, while the MIC29201-4.8WT is supplied in tube packaging. Both use the same TO-220-5 through-hole package for circuit board mounting.

Q: Why should I use the MIC29201-4.8WT instead of the MIC29201-4.8BT?

A: The MIC29201-4.8WT is the recommended choice for new designs and ongoing production due to active manufacturer support, ROHS3 compliance certification, and assured supply continuity. The MIC29201-4.8BT is obsolete and no longer actively manufactured.

Q: Will the MIC29201-4.8WT work in existing circuits designed for the MIC29201-4.8BT?

A: Yes. Identical electrical specifications and TO-220-5 package configuration ensure full functional compatibility in existing circuit designs without modification.
