Substitute Part Grouping Explanation

Substitution of the MIC5236BMM is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, MIC5236YMM, shares the identical base product number (MIC5236) and maintains all critical electrical specifications: positive adjustable output configuration, 150mA output current, 1.24V to 20V output range, 30V maximum input voltage, 0.5V maximum dropout voltage at 150mA, 30µA quiescent current, and comprehensive protection features including load dump, over current, over temperature, over voltage, and reverse polarity protection.

Both parts are housed in the 8-MSOP package with identical pinout and thermal characteristics. The key differentiator is packaging format: MIC5236BMM is supplied in bulk, while MIC5236YMM is supplied in tube packaging. Both operate across the -40°C to 125°C temperature range and feature Enable control functionality.

Engineering Selection Recommendations

The MIC5236YMM is the direct functional equivalent of the MIC5236BMM. Both parts are manufactured by Microchip Technology and share identical electrical specifications and pinout. The MIC5236YMM is currently in active production status, whereas the MIC5236BMM is discontinued, making MIC5236YMM the appropriate selection for new designs and ongoing procurement.

An additional consideration is regulatory compliance: MIC5236YMM carries ROHS3 compliance certification, while MIC5236BMM is RoHS non-compliant. For applications subject to RoHS requirements, MIC5236YMM is the mandated choice. Both parts maintain REACH Unaffected status and carry identical ECCN and HTSUS classifications.

Packaging format differs between the two parts: MIC5236BMM is supplied in bulk, while MIC5236YMM is supplied in tube packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MIC5236YMM directly replace MIC5236BMM in existing designs?

A: Yes. Both parts are electrically and mechanically identical, sharing the same base product number (MIC5236), pinout, package footprint (8-MSOP), and all electrical specifications. No circuit modifications are required.

Q: What is the difference between MIC5236BMM and MIC5236YMM?

A: The primary differences are product status and packaging format. MIC5236BMM is discontinued and supplied in bulk; MIC5236YMM is active and supplied in tube packaging. MIC5236YMM also carries ROHS3 compliance certification, whereas MIC5236BMM is RoHS non-compliant.
