Engineering Selection Recommendations

Primary Substitute: USB7206CT-I/KDX

The USB7206CT-I/KDX is the direct substitute for the obsolete USB7206T-I/KDX. Both components share identical mechanical specifications, package geometry, and core electrical parameters. The substitute part maintains full compatibility with the 100-VQFN (12x12) footprint and supports the required I2C and SPI interface protocols.

The USB7206CT-I/KDX carries an Active product status, ensuring long-term availability and supply chain continuity. This part provides extended interface capabilities including GPIO, I2S, SMBus, and USB protocols beyond the original part's specification, while maintaining backward compatibility with existing I2C and SPI implementations.

Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and MSL 3 moisture sensitivity ratings. The operating temperature range remains constant at -40°C to 85°C across both components.

The substitute part is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype and production-volume procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can the USB7206CT-I/KDX directly replace the USB7206T-I/KDX in existing PCB designs?

A: Yes. Both components utilize identical 100-VQFN (12x12) package geometry with exposed pad configuration. Pin-to-pin compatibility is maintained, allowing direct PCB footprint reuse without layout modifications.

Q: Are there voltage supply differences between these parts?

A: The USB7206T-I/KDX specifies a continuous supply range of 1.09V to 3.6V. The USB7206CT-I/KDX specifies dual voltage ranges: 1.09V to 1.21V and 3V to 3.6V. Both parts operate within the standard 3.3V and 1.2V supply rails used in USB hub controller applications. Existing power delivery designs require no modification.

Q: What interface protocols must be supported for substitution?

A: The minimum required interfaces for substitution are I2C and SPI. The USB7206CT-I/KDX provides these protocols plus additional interfaces (GPIO, I2S, SMBus, USB). Designs utilizing only I2C and SPI protocols experience no functional impact from the additional interface availability.

Q: Are there packaging format differences?

A: The USB7206T-I/KDX was supplied in standard packaging. The USB7206CT-I/KDX is available in Cut Tape (CT) and Digi-Reel® formats, providing flexibility for both prototype development and high-volume manufacturing environments.

Q: Do regulatory compliance certifications differ between these parts?

A: No. Both components maintain identical RoHS3 compliance, REACH Unaffected status, and ECCN EAR99 classification. Regulatory documentation and compliance requirements remain unchanged during substitution.

Q: What is the significance of the Active product status for the substitute part?

A: The USB7206CT-I/KDX carries an Active product status, indicating ongoing manufacturer support, continued production, and long-term supply availability. This contrasts with the Obsolete status of the original part, ensuring designs can transition to a component with established supply chain continuity.

Q: Are there any thermal or operating condition differences?

A: Both components operate across the identical temperature range of -40°C to 85°C. Thermal management requirements, heat dissipation calculations, and operating environment specifications remain unchanged.
