Substitute Part Grouping Explanation

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

  • Output Voltage & Current: Fixed 1.5V output at 600mA capacity
  • Input Voltage Range: 2.7V to 5.5V operation
  • Switching Topology: Buck converter with synchronous rectification
  • Switching Frequency: 2MHz operation
  • Package & Pinout: 10-VFDFN Exposed Pad, 10-MLF® (3x3) form factor
  • Temperature Range: -40°C to 125°C junction temperature rating
  • Mounting: Surface mount configuration

The MIC2205-1.5YML-TR qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Engineering Selection Recommendations

The MIC2205-1.5YML-TR is the direct functional equivalent for the obsolete MIC2205-1.5BML. Selection between these parts is determined by application requirements and supply chain considerations:

MIC2205-1.5YML-TR is the preferred choice for new designs and ongoing production due to:

  • Active product status with current manufacturer support
  • ROHS3 compliance certification
  • Tape & Reel packaging suitable for automated assembly processes
  • Identical electrical and thermal performance specifications

MIC2205-1.5BML may be retained only for legacy system maintenance where existing inventory is available and RoHS non-compliance is acceptable for the application context.

Both parts share identical pinout, package footprint, and electrical characteristics, enabling direct PCB-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can MIC2205-1.5YML-TR replace MIC2205-1.5BML in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The MIC2205-1.5YML-TR operates at the same output voltage (1.5V), current capacity (600mA), input range (2.7V–5.5V), and temperature specifications (-40°C to 125°C). PCB layout and schematic require no modification.

Q: What is the difference between these part numbers?

A: The primary differences are packaging format and product lifecycle status. MIC2205-1.5BML is supplied in bulk packaging and is obsolete. MIC2205-1.5YML-TR is supplied in Tape & Reel format and maintains active status. The "-TR" suffix indicates Tape & Reel packaging. Electrical performance is identical.

Q: Is the 10-MLF® package footprint identical between both parts?

A: Yes. Both parts use the 10-VFDFN Exposed Pad package in 10-MLF® (3x3) form factor. PCB footprints are directly compatible with no layout changes required.

Q: Does RoHS compliance affect functional performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical or thermal performance. Both parts deliver identical functional specifications. The MIC2205-1.5YML-TR offers ROHS3 compliance, which may be required for certain applications or markets.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, with packaging consideration. The MIC2205-1.5YML-TR Tape & Reel format is optimized for automated pick-and-place assembly. The MIC2205-1.5BML bulk format requires manual handling or custom feeder setup. Both parts are surface mount compatible.
