MIC2205-1.5BML TR Equivalent & Substitute Parts

Part Overview

The MIC2205-1.5BML TR is a buck switching regulator IC from Microchip Technology designed for step-down voltage conversion. It delivers a fixed 1.5V output at 600mA with a 2MHz switching frequency and operates across an input voltage range of 2.7V to 5.5V. The device features a synchronous rectifier and is housed in a 10-VFDFN package with exposed pad.

The MIC2205-1.5BML TR is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC2205-1.5BML TR is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck switching regulator with step-down conversion
• Output Voltage: Fixed 1.5V output
• Output Current: 600mA capability
• Input Voltage Range: 2.7V to 5.5V
• Switching Frequency: 2MHz
• Synchronous Rectifier: Present
• Package: 10-VFDFN Exposed Pad, 10-MLF® (3x3)
• Operating Temperature Range: -40°C to 125°C (TJ)
• Mounting Type: Surface Mount

The MIC2205-1.5YML-TR meets all these criteria and is therefore a direct functional equivalent. The primary difference between the main part and its substitute is the packaging format (tape & reel vs. bulk) and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MIC2205-1.5YML-TR is the direct substitute for the MIC2205-1.5BML TR. Both devices share identical electrical specifications, switching characteristics, and physical package dimensions.

Product Status Consideration: The MIC2205-1.5BML TR is obsolete, while the MIC2205-1.5YML-TR is active. For new designs or ongoing production, the active part number is the appropriate selection.

Compliance Consideration: The MIC2205-1.5YML-TR is ROHS3 compliant, whereas the MIC2205-1.5BML TR is RoHS non-compliant. Applications subject to RoHS regulations should transition to the MIC2205-1.5YML-TR.

Packaging Format: The MIC2205-1.5YML-TR is supplied in tape & reel format, which is standard for automated assembly processes. The MIC2205-1.5BML TR was supplied in bulk format. Verify that your assembly equipment and procurement workflow accommodate tape & reel packaging.

Frequently Asked Questions (FAQ)

Q: Are the MIC2205-1.5BML TR and MIC2205-1.5YML-TR electrically identical?

A: Yes. Both devices deliver identical electrical performance across all specified parameters: 1.5V fixed output, 600mA output current, 2.7V to 5.5V input range, 2MHz switching frequency, and -40°C to 125°C operating temperature range.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (bulk vs. tape & reel). The electrical and mechanical specifications are identical.

Q: Can I use the MIC2205-1.5YML-TR as a direct replacement in existing designs?

A: Yes. The MIC2205-1.5YML-TR is a direct functional equivalent with identical package dimensions (10-VFDFN, 10-MLF® 3x3), pin configuration, and electrical characteristics. No circuit modifications are required.

Q: Why is the MIC2205-1.5BML TR marked as obsolete?

A: Microchip Technology has transitioned this product to end-of-life status. The MIC2205-1.5YML-TR represents the active equivalent and is the recommended part for new procurement.

Q: Does the tape & reel packaging affect circuit performance?

A: No. Tape & reel packaging is a supply format only and does not affect electrical performance or reliability. It is the standard format for high-volume automated assembly.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the same temperature range (-40°C to 125°C TJ) and feature identical thermal characteristics due to matching package geometry and internal design.
