Substitute Part Grouping Explanation

Substitution of the MIC2012-2ZQS TR is determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Both parts must originate from Microchip Technology to ensure design compatibility and support continuity
• Function & Interface: Both must serve as USB controllers with identical USB interface protocol
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V) and supply current (16µA) must match exactly
• Package Compatibility: Both must use the 16-QSOP package (16-SSOP, 0.154", 3.90mm Width) to ensure PCB footprint compatibility
• Operating Temperature Range: Both must support 0°C ~ 70°C operation
• Compliance Standards: Both must maintain ROHS3 compliance and REACH Unaffected status

The MIC2072-2PZQS-TR meets all substitution criteria and is classified as a parametric equivalent with active product status, making it suitable for replacement applications.
