Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB7056T-I/KDX is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts utilize the 100-VQFN (12x12) package with exposed pad, ensuring mechanical and thermal compatibility
• Manufacturer Consistency: Microchip Technology manufactures both the original and substitute component, maintaining design ecosystem alignment
• Functional Category: Both components serve as USB hub controllers with GPIO interface capability
• Compliance Standards: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements
• Moisture Sensitivity: Identical MSL rating of 3 (168 Hours) ensures equivalent handling and storage requirements

The USB7016T-I/KDX qualifies as a manufacturer-recommended substitute based on these aligned parameters, despite differences in specific USB standard support and interface protocol availability.

Frequently Asked Questions (FAQ)

Q: Can the USB7016T-I/KDX be used as a direct replacement for the USB7056T-I/KDX?

A: Yes, the USB7016T-I/KDX qualifies as a direct substitute based on identical package geometry (100-VQFN 12x12), matching pin count, and equivalent electrical interface requirements. Both components are manufactured by Microchip Technology and maintain identical MSL ratings and compliance certifications.

Q: What are the key differences between these two hub controllers?

A: The primary differences are product status (obsolete versus active), USB standard support (USB 3.1 versus USB 2.0/USB 3.2), available interface protocols (USB7056T includes I2S and UART; USB7016T includes native USB interface), and automotive qualification (USB7016T carries AEC-Q100 certification). The USB7016T also provides specified operating temperature range (-40°C to 85°C) and supply voltage specifications.

Q: Are there any interface protocol compatibility concerns?

A: The USB7056T-I/KDX supports GPIO, I2C, I2S, SPI, and UART interfaces. The USB7016T-I/KDX supports GPIO, I2C, SPI, and USB interfaces. Applications requiring I2S or UART functionality must evaluate whether the USB7016T's native USB interface capability provides equivalent functionality for the intended design.

Q: Does the package change affect PCB layout?

A: No. Both components use the 100-VQFN (12x12) package with exposed pad. PCB footprints, thermal management considerations, and assembly processes remain identical.

Q: What is the MSL rating significance?

A: Both components carry MSL 3 (168 Hours) rating, indicating identical moisture sensitivity levels and storage/handling requirements. No changes to component storage, handling procedures, or reflow processes are necessary.

Q: Is the automotive qualification relevant for non-automotive applications?

A: The AEC-Q100 qualification of the USB7016T-I/KDX indicates enhanced reliability testing and quality assurance. This qualification is beneficial for any application requiring high reliability, though it is not mandatory for non-automotive designs.
