Substitute Part Grouping Explanation

Substitution of the MIC2204BML is determined by strict equivalence across the following critical parameters:

• Input voltage range: 2.3V to 5.5V
• Output voltage range: 1V to 5.5V (adjustable)
• Output current capability: 600mA
• Switching frequency: 2MHz
• Synchronous rectifier topology: Yes
• Package type: 10-VFDFN Exposed Pad, 10-MLF® (3x3)
• Operating temperature range: -40°C to 125°C
• Mounting type: Surface Mount

The MIC2204YML qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MIC2204YML is the direct substitute for the obsolete MIC2204BML. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product lifecycle status: the MIC2204BML is obsolete, while the MIC2204YML maintains active production status with Microchip Technology.

An additional consideration is regulatory compliance. The MIC2204YML meets ROHS3 compliance requirements, whereas the MIC2204BML is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the MIC2204YML is the appropriate selection. Both devices maintain REACH Unaffected status and carry the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the MIC2204YML directly replace the MIC2204BML in existing designs?

A: Yes. The MIC2204YML is electrically and mechanically identical to the MIC2204BML. Pin configuration, package footprint, and functional specifications are equivalent, enabling direct substitution without circuit modification.

Q: What is the difference between the MIC2204BML and MIC2204YML?

A: The devices are functionally identical. The primary differences are product status (MIC2204BML is obsolete; MIC2204YML is active) and RoHS compliance (MIC2204BML is non-compliant; MIC2204YML is ROHS3 compliant).

Q: Are there packaging differences between these parts?

A: Both devices use the 10-VFDFN Exposed Pad, 10-MLF® (3x3) package. The MIC2204BML is supplied without specified packaging, while the MIC2204YML is supplied in Tube packaging. The physical package and footprint are identical.

Q: Which part should be selected for new designs?

A: The MIC2204YML should be selected for new designs. It is in active production and meets current RoHS compliance standards, ensuring long-term availability and regulatory alignment.

Q: Are the electrical specifications identical between these parts?

A: Yes. Input voltage range (2.3V to 5.5V), output voltage range (1V to 5.5V), output current (600mA), switching frequency (2MHz), and operating temperature range (-40°C to 125°C) are identical across both devices.
