Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC5259-2.5YML-TR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.5V
• Output current capability of 300mA
• Maximum input voltage of 6V
• Dropout voltage specification of 0.55V @ 300mA
• Package configuration: 6-VDFN Exposed Pad, 6-MLF® (6-DFN 2x2)
• Surface Mount mounting type
• Operating temperature range: -40°C to 125°C
• Active product status
• RoHS3 compliance

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. No deviations from these specifications are permitted for true substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MIC5259-2.5YML-TR is an Active product with full RoHS3 compliance and REACH unaffected status, making it suitable for current design implementations. When selecting this part or its equivalents, confirm that the Active product status and compliance certifications align with your application requirements and supply chain policies. The part's Moisture Sensitivity Level (MSL) of 1 (Unlimited) indicates no special moisture handling precautions are required during storage or assembly.

Frequently Asked Questions (FAQ)

Q: What makes a part a true substitute for the MIC5259-2.5YML-TR?

A: A true substitute must match all critical electrical parameters: 2.5V fixed output voltage, 300mA output current, 6V maximum input voltage, 0.55V dropout voltage at 300mA, and the identical 6-VDFN Exposed Pad package. The part must also maintain the same operating temperature range (-40°C to 125°C) and compliance status.

Q: Can I use a different output voltage variant of the MIC5259 series?

A: No. The MIC5259 series includes multiple fixed output voltage options. Only the 2.5V variant (MIC5259-2.5YML-TR) is compatible as a direct substitute. Other voltage variants are not interchangeable.

Q: Is the 6-DFN (2x2) package compatible with 6-VDFN Exposed Pad footprints?

A: Yes. The supplier device package designation 6-DFN (2x2) refers to the same physical package as 6-VDFN Exposed Pad, 6-MLF®. These designations are equivalent for PCB layout and assembly purposes.

Q: What is the significance of the Tape & Reel (TR) packaging designation?

A: Tape & Reel packaging indicates the part is supplied on carrier tape in reel format, suitable for automated assembly processes. This is a supply format specification and does not affect electrical or mechanical compatibility.

Q: Does the part require special handling due to its Moisture Sensitivity Level?

A: No. An MSL rating of 1 (Unlimited) means the part has no moisture sensitivity restrictions and does not require special dry storage or baking procedures prior to assembly.
