Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC5236-3.3BMM is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 3.3V
• Output current rating of 150mA minimum
• Maximum input voltage of 30V or greater
• Maximum dropout voltage of 0.5V @ 150mA or lower
• 8-MSOP package configuration
• Identical protection feature set (Load Dump, Over Current, Over Temperature, Over Voltage, Reverse Polarity)
• Enable control functionality
• Operating temperature range of -40°C to 125°C or wider

The MIC5236-3.3YMM meets all substitution criteria as a direct equivalent from the same manufacturer and product series, with identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The MIC5236-3.3YMM is the direct substitute for the MIC5236-3.3BMM. Both parts share identical electrical specifications, output characteristics, and package configuration. The primary distinction is product status and regulatory compliance: the MIC5236-3.3YMM is currently active in production with ROHS3 compliance, whereas the MIC5236-3.3BMM is discontinued and RoHS non-compliant.

For new designs and ongoing production requiring 3.3V linear regulation at 150mA with comprehensive protection features in 8-MSOP packaging, the MIC5236-3.3YMM is the appropriate selection. The tube packaging of the MIC5236-3.3YMM accommodates both production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the MIC5236-3.3YMM directly replace the MIC5236-3.3BMM in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching output voltage, current rating, dropout voltage, protection features, and 8-MSOP package configuration. Pin-for-pin compatibility is maintained.

Q: What is the difference between the bulk and tube packaging options?

A: The MIC5236-3.3BMM was supplied in bulk packaging, while the MIC5236-3.3YMM is supplied in tube packaging. Both contain the same die and electrical performance. Tube packaging is standard for active production parts and provides better handling and traceability for manufacturing environments.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical specifications. The MIC5236-3.3YMM's ROHS3 compliance reflects current manufacturing standards without altering the device's functional characteristics.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the 8-MSOP package with identical pinout and functionality. PCB layouts and schematics require no modification for substitution.

Q: What inventory status should be considered for procurement?

A: The MIC5236-3.3YMM has significantly higher inventory availability (4144 Pcs) compared to the discontinued MIC5236-3.3BMM (911 Pcs). For new procurement, the MIC5236-3.3YMM is the recommended choice due to active production status and supply continuity.
