Substitute Part Grouping Explanation

Substitute parts for the MIC5255-3.3BML-TR are identified based on strict electrical and mechanical parameter matching within the linear voltage regulator category. The substitution criteria are:

• Output voltage: 3.3V fixed
• Output current capacity: 150mA
• Maximum input voltage: 6V
• Voltage dropout: 0.25V @ 150mA
• Package type: 6-DFN (2x2) with exposed pad
• Protection features: Over-current, over-temperature, and UVLO
• Operating temperature range: -40°C ~ 125°C
• Mounting type: Surface Mount

Parts meeting all these parameters are classified as direct parametric equivalents and can be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MIC5255-3.3YML-TR is a direct parametric equivalent to the MIC5255-3.3BML-TR. Both devices share identical electrical specifications, package configuration, and functional characteristics.

The primary distinction is product status and regulatory compliance. The MIC5255-3.3YML-TR is currently active in production with ROHS3 compliance certification, whereas the MIC5255-3.3BML-TR is discontinued and RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance, the MIC5255-3.3YML-TR is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.
