MIC5216BMM Equivalent & Substitute Parts

Part Overview

The MIC5216BMM is a linear voltage regulator IC from Microchip Technology designed for positive adjustable output applications. It delivers 500mA output current in an 8-MSOP surface mount package with integrated protection features including over-current, over-temperature, and reverse polarity protection. The device operates across an industrial temperature range of -40°C to 125°C.

The MIC5216BMM is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure availability for new production runs or system updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC5216BMM is based on the following critical parameters:

• Output Configuration & Type: Both main and substitute parts must provide positive adjustable output with single regulator configuration
• Current Rating: 500mA output current requirement must be met or exceeded
• Package Compatibility: 8-MSOP surface mount package ensures PCB layout compatibility
• Protection Features: Over-current and over-temperature protection are mandatory; reverse polarity protection is required
• Operating Temperature Range: -40°C to 125°C industrial range must be supported
• Input Voltage Handling: Substitute must accommodate the input voltage specifications of the application

The MIC5239YMM meets all substitution criteria while offering enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MIC5239YMM is the direct substitute for the MIC5216BMM based on the following factors:

Product Status: The MIC5216BMM is obsolete, while the MIC5239YMM is active. Active product status ensures ongoing availability and manufacturing support.

Compliance: The MIC5239YMM is ROHS3 compliant, whereas the MIC5216BMM is non-compliant. For applications requiring regulatory compliance with modern environmental standards, the MIC5239YMM is the appropriate choice.

Functional Compatibility: Both devices share identical package geometry (8-MSOP), output current rating (500mA), and operating temperature range (-40°C to 125°C). Pin-to-pin compatibility is maintained.

Enhanced Specifications: The MIC5239YMM provides superior performance characteristics including higher maximum input voltage (30V vs. 12V), lower dropout voltage (0.35V typical vs. 0.6V maximum), and additional over-voltage protection.

Frequently Asked Questions (FAQ)

Q: Can the MIC5239YMM directly replace the MIC5216BMM on existing PCBs?

A: Yes. Both devices use the 8-MSOP package with identical pinout and footprint. No PCB modifications are required for physical substitution.

Q: What are the key differences between these two regulators?

A: The primary differences are product status (obsolete vs. active), compliance certification (non-compliant vs. ROHS3), maximum input voltage (12V vs. 30V), and dropout voltage performance (0.6V max vs. 0.35V typical). The MIC5239YMM also includes over-voltage protection.

Q: Are there any application limitations when switching from MIC5216BMM to MIC5239YMM?

A: No limitations exist for applications within the MIC5216BMM's original specifications. The MIC5239YMM's higher input voltage rating and lower dropout voltage provide additional design margin.

Q: What is the moisture sensitivity level for both parts?

A: Both the MIC5216BMM and MIC5239YMM have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts available in the same packaging options?

A: Both devices are supplied in 8-MSOP packages. The MIC5239YMM is available in Tube packaging, while the MIC5216BMM packaging specification was not provided in the available data.
