Substitute Part Grouping Explanation
Substitution of the MIC2072-2PCQS is determined by strict equivalence across the following critical parameters:
- Manufacturer and Base Product Series: Both parts must originate from Microchip Technology and share the MIC2072 base product number
- Functional Classification: USB power controller with dual-channel capability
- Electrical Specifications: Identical voltage supply range (4.5V ~ 5.5V) and supply current (16µA)
- Operating Temperature Range: Matching 0°C ~ 70°C specification
- Package and Pinout: Identical 16-QSOP package configuration ensuring mechanical and electrical compatibility
- Interface Protocol: USB protocol compliance
The MIC2072-2PZQS qualifies as a direct substitute based on complete alignment with these parameters. The primary distinction between the main part and its substitute relates to product status and packaging format, not functional or electrical characteristics.

Engineering Selection Recommendations
The MIC2072-2PZQS is the direct equivalent substitute for the discontinued MIC2072-2PCQS. Both components are functionally identical across all electrical and mechanical parameters. The MIC2072-2PZQS maintains active product status with significantly higher inventory availability (4893 pieces versus 754 pieces), ensuring reliable supply chain access.
A key distinction exists in regulatory compliance: the MIC2072-2PZQS achieves ROHS3 compliance, whereas the MIC2072-2PCQS is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the MIC2072-2PZQS is the preferred selection. For legacy systems or applications without RoHS requirements, both parts remain electrically and mechanically interchangeable.
The packaging difference (tube format for the substitute versus standard packaging for the main part) does not affect component functionality or performance and relates solely to distribution and handling logistics.
Frequently Asked Questions (FAQ)
Q: Can the MIC2072-2PZQS be used as a direct replacement for the MIC2072-2PCQS?
A: Yes. Both components share identical electrical specifications, operating parameters, and package configuration. The MIC2072-2PZQS is a direct functional equivalent with no design modifications required.
Q: What is the significance of the RoHS compliance difference?
A: The MIC2072-2PZQS is ROHS3 compliant, while the MIC2072-2PCQS is RoHS non-compliant. For applications requiring RoHS compliance or subject to environmental regulations, the MIC2072-2PZQS is the appropriate selection. For applications without RoHS requirements, both parts are functionally equivalent.
Q: Are the package dimensions identical between these parts?
A: Yes. Both components use the 16-QSOP package with identical dimensions (16-SSOP, 0.154" width, 3.90mm). PCB layouts and footprints are fully compatible.
Q: Does the tube packaging format affect component performance?
A: No. Packaging format (tube versus standard) relates only to distribution and handling. Component performance, electrical characteristics, and reliability are unaffected.
Q: What is the inventory status for the substitute part?
A: The MIC2072-2PZQS is currently active with 4893 pieces in stock, providing reliable availability compared to the discontinued MIC2072-2PCQS.
Q: Are the operating temperature ranges identical?
A: Yes. Both components operate across the identical 0°C to 70°C temperature range with no performance variation.
