Key Parameters

Substitute Part Grouping Explanation

The MIC5331-MMYMT-TR qualifies as a parametric equivalent based on the following criteria:

Matching Parameters:

• Identical manufacturer (Microchip Technology)
• Identical package and pinout (8-VFDFN Exposed Pad, 8-MLF®)
• Identical output configuration (Positive, Fixed, Dual 2.8V)
• Identical output current rating (300mA per channel)
• Identical maximum input voltage (5.5V)
• Identical operating temperature range (-40°C ~ 125°C)
• Identical compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Identical mounting type (Surface Mount)

Allowable Variations: Dropout voltage and quiescent current specifications differ within acceptable ranges for this product category, reflecting design optimization in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both MIC5330-MMYML-TR and MIC5331-MMYMT-TR are Active status products from Microchip Technology with identical ROHS3 compliance and REACH unaffected certifications. Selection between these parts depends on application-specific requirements:

The MIC5330-MMYML-TR features lower dropout voltage (0.2V) and higher quiescent current (120 µA), suitable for applications requiring minimal voltage headroom or where dropout performance is critical.

The MIC5331-MMYMT-TR features lower quiescent current (50 µA) and slightly higher dropout voltage (0.24V), suitable for battery-powered or low-power applications where standby current consumption is a primary design constraint.

Both parts maintain identical pinout, package footprint, and electrical output specifications, enabling direct substitution within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can MIC5331-MMYMT-TR replace MIC5330-MMYML-TR in existing designs?

A: Yes. Both parts share identical package (8-VFDFN Exposed Pad, 8-MLF®), pinout, output voltage (2.8V dual), output current (300mA per channel), and input voltage rating (5.5V maximum). Dropout voltage increases from 0.2V to 0.24V, and quiescent current decreases from 120 µA to 50 µA. Verify that the application can tolerate the 0.04V additional dropout voltage before substitution.

Q: Are the parts pin-compatible?

A: Yes. Both parts use the 8-MLF® (2x2) package with identical pinout and mechanical dimensions, enabling direct PCB footprint compatibility.

Q: What compliance certifications apply to both parts?

A: Both MIC5330-MMYML-TR and MIC5331-MMYMT-TR are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: Which part should be selected for low-power applications?

A: The MIC5331-MMYMT-TR is preferred for applications prioritizing low quiescent current (50 µA versus 120 µA), typical in battery-powered or energy-constrained designs.

Q: Which part should be selected for applications with tight voltage headroom?

A: The MIC5330-MMYML-TR is preferred for applications requiring minimal dropout voltage (0.2V versus 0.24V), typical in systems with limited input voltage margin.
