Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC29302BT is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Voltage specifications (Input Max: 26V, Output Min: 1.25V, Output Max: 25V)
• Dropout voltage (0.6V @ 3A)
• Output current (3A)
• Control features (Enable)
• Protection features (Over Current, Over Temperature, Reverse Polarity, Transient Voltage)
• Operating temperature range (-40°C ~ 125°C)
• Package / Case (TO-220-5)
• Mounting type (Through Hole)

The MIC29302WT meets all these criteria and is classified as an active product, making it a direct functional equivalent to the obsolete MIC29302BT.

Parameter Comparison

Engineering Selection Recommendations

The MIC29302WT is the direct substitute for the obsolete MIC29302BT. Both devices share identical electrical and mechanical specifications, including voltage ratings, current capacity, protection features, and thermal operating range. The primary distinction is product status and regulatory compliance: the MIC29302WT is an active product with ROHS3 compliance, whereas the MIC29302BT is obsolete and RoHS non-compliant. For new designs or production continuity, the MIC29302WT is the appropriate selection. The MIC29302WT is available in tube packaging with significantly higher inventory levels (24,950 pcs) compared to the MIC29302BT (1,225 pcs).

Frequently Asked Questions (FAQ)

Q: Can the MIC29302WT directly replace the MIC29302BT in existing designs?

A: Yes. The MIC29302WT is electrically and mechanically identical to the MIC29302BT across all specified parameters, including voltage ratings, current output, protection features, and operating temperature range. Both devices use the TO-220-5 package and are through-hole mounted.

Q: What is the difference between the MIC29302BT and MIC29302WT?
