Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC29512BT are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Identical manufacturer (Microchip Technology)
• Identical package type (TO-220-5)
• Identical mounting type (Through Hole)
• Matching input voltage range (2.24V ~ 20V)
• Matching output voltage range (1.24V ~ 15V)
• Matching number of outputs (1)
• Matching operating temperature range (0°C ~ 125°C)
• Same base product number (MIC29512)

The MIC29512WT meets all substitution criteria and is classified as an active product, providing a direct replacement path for the obsolete MIC29512BT.

Parameter Comparison

Engineering Selection Recommendations

The MIC29512WT is the direct substitute for the MIC29512BT. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product status: the MIC29512BT is obsolete while the MIC29512WT is active and currently in production.

The MIC29512WT offers improved regulatory compliance, meeting ROHS3 standards compared to the non-compliant status of the MIC29512BT. This compliance improvement makes the MIC29512WT the preferred choice for new designs and component replacement in systems requiring modern environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the MIC29512WT directly replace the MIC29512BT in existing applications?

A: Yes. Both components share identical electrical parameters (input voltage range 2.24V ~ 20V, output voltage range 1.24V ~ 15V), identical package type (TO-220-5), and identical mounting configuration (through hole). Direct substitution is supported without circuit modification.

Q: What is the difference between the MIC29512BT and MIC29512WT?

A: The components are electrically and mechanically identical. The MIC29512BT is obsolete, while the MIC29512WT is an active product. The MIC29512WT meets ROHS3 compliance standards, whereas the MIC29512BT does not.

Q: Are there any packaging differences between these parts?

A: Both components use the TO-220-5 package with through-hole mounting. The MIC29512BT is supplied in standard packaging, while the MIC29512WT is supplied in tube packaging. This difference does not affect electrical or mechanical compatibility.

Q: What certifications apply to these components?

A: Both the MIC29512BT and MIC29512WT are classified as REACH Unaffected and carry the ECCN designation EAR99. The MIC29512WT additionally meets ROHS3 compliance requirements.
