USB7052T/KDX Equivalent & Substitute Parts

Part Overview

The USB7052T/KDX is a USB Hub Controller manufactured by Microchip Technology, designed for USB 3.1 interface applications with I2C communication protocol. This component is packaged in a 100-VQFN (12x12) format with exposed pad and is currently classified as obsolete. Due to its obsolete status, identifying functionally compatible substitute parts is essential for ongoing design support, production continuity, and system maintenance. The primary substitute maintains core functionality while offering active product status and expanded interface capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB7052T/KDX is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 100-VQFN (12x12) package with exposed pad to ensure PCB layout and thermal management compatibility
• Functional Classification: Both parts must serve as USB Hub Controllers
• Protocol Support: Both parts must support USB protocol with I2C interface capability
• Standards Compliance: Both parts must support USB 3.1 standard
• Operating Temperature Range: Both parts must operate within 0°C ~ 70°C
• Regulatory Compliance: Both parts must maintain ROHS3, REACH Unaffected, and EAR99 classifications

The USB7052NT/KDX qualifies as a direct substitute based on these parameters. While the substitute part offers expanded interface options (GPIO, SPI, UART in addition to I2C) and dual voltage supply capability, these represent functional enhancements that do not compromise compatibility with existing designs requiring the original part's core specifications.

Parameter Comparison

Engineering Selection Recommendations

The USB7052NT/KDX is the manufacturer-recommended substitute for the obsolete USB7052T/KDX. Both parts maintain identical package specifications, operating temperature ranges, and regulatory compliance certifications. The substitute part carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

The USB7052NT/KDX provides expanded interface flexibility through additional GPIO, SPI, and UART capabilities while maintaining full I2C compatibility required by existing designs. The dual voltage supply specification (1.08V ~ 1.32V and 3V ~ 3.6V) of the substitute part accommodates a broader range of power delivery architectures without compromising electrical compatibility in applications designed for the original part's specifications.

Both parts maintain identical MSL ratings, ROHS3 compliance, and REACH unaffected status, ensuring equivalent handling, storage, and environmental compliance requirements throughout the component lifecycle.

Frequently Asked Questions (FAQ)

Q: Can the USB7052NT/KDX be used as a direct replacement for the USB7052T/KDX in existing designs?

A: Yes. Both parts share identical package specifications (100-VQFN 12x12 with exposed pad), operating temperature range (0°C ~ 70°C), and regulatory compliance certifications. The substitute part maintains full I2C interface compatibility and USB 3.1 standard support required by designs using the original part.

Q: What are the key differences between these parts?

A: The USB7052NT/KDX offers expanded interface options (GPIO, SPI, UART in addition to I2C) and specified dual voltage supply capability (1.08V ~ 1.32V, 3V ~ 3.6V), whereas the original part does not specify supply voltage parameters. The substitute part carries active product status versus the obsolete status of the original part.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts maintain identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), requiring equivalent handling, storage, and reflow procedures throughout manufacturing and assembly processes.

Q: Does the substitute part maintain the same regulatory compliance?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8542.39.0001.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology evolution, and production lifecycle decisions. The availability of the active substitute part ensures continued design support and component sourcing for applications requiring USB Hub Controller functionality in the 100-VQFN package format.
