Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC29204BN is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable/Fixed)
• Voltage specifications (Input Max: 26V, Output Min/Fixed: 1.24V/5V, Output Max: 26V)
• Current rating (400mA output)
• Dropout voltage (0.75V @ 400mA)
• Quiescent current (300 µA)
• Operating temperature range (-40°C ~ 125°C)
• Package type (8-DIP through-hole)
• Control features (Enable)
• Protection features (Load Dump, Over Current, Reverse Polarity)

The MIC29204YN meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC29204BN is obsolete and no longer in active production. The MIC29204YN is the direct functional equivalent with identical electrical and mechanical specifications. Selection of MIC29204YN is supported by its active product status and ROHS3 compliance certification, which aligns with current regulatory requirements and supply chain availability. Both parts share identical package geometry, pinout, and performance characteristics, enabling direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can MIC29204YN replace MIC29204BN in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is possible without design modification.

Q: What is the primary difference between these parts? A: The MIC29204BN is obsolete, while MIC29204YN is active. MIC29204YN also carries ROHS3 compliance certification, whereas MIC29204BN is RoHS non-compliant.

Q: Are the packages identical? A: Yes. Both use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout and mechanical dimensions.

Q: What are the key electrical parameters that define substitution? A: Output configuration (Positive), output type (Adjustable/Fixed), voltage range (26V input max, 1.24V/5V output min/fixed, 26V output max), 400mA output current, 0.75V dropout at 400mA, 300 µA quiescent current, and -40°C to 125°C operating temperature.

Q: Is there any difference in control or protection features? A: No. Both parts include Enable control and Load Dump, Over Current, and Reverse Polarity protection features.
