Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC2202BML is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck switching regulator with step-down configuration
• Output Characteristics: Positive, adjustable output from 0.5V to 5.5V
• Electrical Performance: 600mA output current, 2MHz switching frequency, integrated synchronous rectification
• Input Voltage Range: 2.3V to 5.5V
• Package & Pinout: 10-VFDFN exposed pad (10-MLF®, 3x3mm)
• Operating Temperature Range: -40°C to 125°C junction temperature
• Mounting: Surface mount

The MIC2202YML meets all these criteria and is identified as a direct substitute. Both parts share identical electrical specifications, package geometry, and functional characteristics. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC2202YML is the direct substitute for the obsolete MIC2202BML. Both devices are electrically and mechanically identical across all specified parameters. The MIC2202YML is currently in active production status, ensuring long-term availability and supply chain continuity.

The MIC2202YML carries ROHS3 compliance certification, whereas the MIC2202BML is non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the MIC2202YML is the appropriate selection. For legacy systems or applications without compliance requirements, either part meets the electrical and functional specifications.

Both parts maintain identical moisture sensitivity levels (MSL 1, Unlimited) and REACH status, indicating equivalent handling and environmental compliance profiles.

Frequently Asked Questions (FAQ)

Q: Are MIC2202BML and MIC2202YML pin-for-pin compatible?

A: Yes. Both devices use the 10-VFDFN exposed pad package (10-MLF®, 3x3mm) with identical pinout and electrical characteristics. Direct substitution on the PCB is possible without layout modifications.

Q: What is the primary reason to substitute MIC2202BML with MIC2202YML?

A: The MIC2202BML is obsolete. The MIC2202YML is the active production equivalent, ensuring continued availability and supply chain support. Additionally, the MIC2202YML meets ROHS3 compliance requirements.

Q: Do the devices have identical electrical performance?

A: Yes. Input voltage range (2.3V–5.5V), output voltage range (0.5V–5.5V), output current (600mA), switching frequency (2MHz), and operating temperature range (-40°C to 125°C) are identical across both parts.

Q: Are there packaging differences between these parts?

A: The MIC2202BML is supplied in standard packaging, while the MIC2202YML is supplied in Tube packaging. The physical component package (10-VFDFN exposed pad) is identical. Tube packaging is a standard distribution format and does not affect component functionality or performance.

Q: What is the moisture sensitivity level for these devices?

A: Both the MIC2202BML and MIC2202YML have MSL 1 (Unlimited), indicating the lowest moisture sensitivity classification. Standard handling and storage procedures are sufficient; no special moisture control measures are required.

Q: Can I use MIC2202YML in a design originally specified for MIC2202BML?

A: Yes. The MIC2202YML is a direct functional and mechanical equivalent. No circuit modifications, PCB layout changes, or firmware updates are necessary. The substitution is transparent to the system design.
