MIC49150BMM Equivalent & Substitute Parts

Part Overview

The MIC49150BMM is a linear voltage regulator IC from Microchip Technology designed for positive adjustable output applications. This Surface Mount device delivers 1.5A output current in an 8-MSOP package and operates across an input voltage range up to 6.5V with adjustable output from 0.9V to 5V. The part includes integrated over-current and over-temperature protection with enable control features.

The MIC49150BMM is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement. Direct manufacturer equivalents with identical electrical and mechanical specifications are available to maintain design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC49150BMM is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for:

• Output configuration (Positive)
• Output type (Adjustable)
• Voltage input maximum (6.5V)
• Voltage output range (0.9V to 5V)
• Output current capacity (1.5A)
• Dropout voltage (0.5V @ 1.5A)
• Control features (Enable)
• Protection features (Over Current, Over Temperature)
• Operating temperature range (-40°C ~ 125°C)
• Package type (8-MSOP)
• Mounting type (Surface Mount)
• Moisture sensitivity level (MSL 1)

The MIC49150YMM meets all these criteria as a direct equivalent from the same manufacturer, sharing the identical MIC49150 base product number with only a different temperature grade designation suffix.

Parameter Comparison

Engineering Selection Recommendations

The MIC49150YMM is a direct functional equivalent to the MIC49150BMM with identical electrical performance and mechanical compatibility. Both parts share the MIC49150 base product number and deliver equivalent circuit performance across all specified parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MIC49150BMM is discontinued at DiGi Electronics, whereas the MIC49150YMM maintains active product status with higher inventory availability (4448 units versus 1715 units). The MIC49150YMM additionally carries ROHS3 compliance certification, whereas the MIC49150BMM is RoHS non-compliant.

For new designs or ongoing production requiring regulatory compliance with modern environmental standards, the MIC49150YMM is the appropriate selection. For legacy applications where RoHS compliance is not a requirement, either part delivers identical functional performance.

Frequently Asked Questions (FAQ)

Q: Are the MIC49150BMM and MIC49150YMM pin-compatible?

A: Yes. Both parts use the 8-MSOP package with identical pinout and mechanical dimensions (0.118", 3.00mm Width). Direct PCB substitution is possible without layout modifications.

Q: What is the difference between the "B" and "Y" designations in the part numbers?

A: The suffix letter indicates the temperature grade and manufacturing specification variant. Both parts operate across the identical -40°C to 125°C temperature range and deliver equivalent electrical performance. The primary difference is regulatory compliance status.

Q: Can the MIC49150YMM replace the MIC49150BMM in existing designs?

A: Yes. The MIC49150YMM is a direct substitute with identical electrical specifications, output current capacity (1.5A), voltage ranges (0.9V to 5V output), dropout voltage (0.5V @ 1.5A), and protection features (over-current and over-temperature). No circuit modifications are required.
