MIC5331-MMYMT-TR Equivalent & Substitute Parts

Part Overview

The MIC5331-MMYMT-TR is a linear voltage regulator IC from Microchip Technology designed for power management applications. This dual-output positive fixed regulator delivers 300mA per channel at fixed 2.8V outputs with a maximum input voltage of 5.5V. The device is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary for supply chain continuity, design flexibility, or specific application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the MIC5331-MMYMT-TR is determined by strict alignment with the following critical parameters:

  • Dual-output configuration: Exactly 2 regulators required
  • Fixed output voltage: Both outputs must be fixed at 2.8V
  • Output current capability: Minimum 300mA per channel
  • Maximum input voltage: 5.5V or higher
  • Package compatibility: 8-MLF® (2x2) form factor with exposed pad
  • Dropout voltage: Maximum 0.24V @ 300mA per channel
  • Surface mount technology: VFDFN package type
  • Regulatory compliance: ROHS3 compliant minimum

Only parts meeting all these parameters simultaneously qualify as direct substitutes. Deviations in any single parameter disqualify a part from this equivalency group.

Engineering Selection Recommendations

The MIC5331-MMYMT-TR maintains active production status with full ROHS3 compliance and REACH unaffected classification. Selection of equivalent parts should prioritize devices with identical active product status and matching regulatory certifications. The part carries EAR99 export classification and standard HTSUS code 8542.39.0001.

When evaluating substitutes, confirm that the candidate part maintains the same MSL 1 rating to ensure compatibility with standard moisture-controlled storage and handling procedures. Surface mount assembly compatibility requires verification of the 8-MLF® (2x2) package footprint and exposed pad thermal characteristics.

Frequently Asked Questions (FAQ)

Q: What makes a part a true substitute for the MIC5331-MMYMT-TR?

A: A substitute must match all critical parameters: dual 2.8V fixed outputs at 300mA each, maximum 5.5V input, 0.24V maximum dropout at rated current, 8-MLF® (2x2) package, and ROHS3 compliance. Deviation in any parameter disqualifies the part.

Q: Can I use a single-output regulator as a substitute?

A: No. The MIC5331-MMYMT-TR is a dual-output device. Single-output regulators do not meet the functional requirements of this part.

Q: Are there packaging alternatives within the same electrical specifications?

A: The provided data specifies only the 8-VFDFN Exposed Pad, 8-MLF® (2x2) package. Alternative packages are not included in the substitute list.

Q: What is the significance of the 0.24V dropout specification?

A: This dropout voltage at 300mA per channel defines the minimum input-to-output voltage differential required for proper regulation. Substitutes must maintain this specification to ensure circuit performance.

Q: Does MSL 1 rating affect my PCB assembly process?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. Standard handling and storage procedures are sufficient without special precautions.

Q: How do I verify package compatibility on my PCB?

A: Confirm your PCB footprint matches the 8-MLF® (2x2) land pattern with exposed pad thermal connection. Consult the device datasheet for exact pad dimensions and spacing.
