Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB7206T/KDX is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the same 100-VQFN (12x12) Exposed Pad package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Electrical Specifications: The substitute must operate within the specified voltage supply range of 1.09V ~ 3.6V and maintain the same operating temperature range of 0°C ~ 70°C to ensure functional equivalence in the target application.

Protocol and Interface Support: The substitute must support USB protocol as the primary function and maintain I2C and/or SPI interface capabilities for system integration.

Standards Compliance: The substitute must support USB 3.1 standard or higher to maintain backward compatibility and performance requirements.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and REACH Unaffected status to satisfy environmental and regulatory requirements.

The USB7206CT/KDX qualifies as a direct substitute based on these parameters. It shares the identical package footprint, overlapping voltage supply specifications, compatible interface protocols, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: USB7206CT/KDX

The USB7206CT/KDX is the direct substitute for the obsolete USB7206T/KDX. Both components share identical base product architecture (USB7206 series), package specifications, and core electrical parameters. The substitute maintains ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements equivalent to the main part.

The USB7206CT/KDX is classified as an Active product with significantly higher inventory availability (1,000,299 pieces) compared to the obsolete main part (939 pieces). This status change from Obsolete to Active ensures long-term supply chain viability and supports sustained production requirements.

The substitute provides expanded interface capabilities including GPIO, I2S, and SMBus protocols in addition to the I2C and SPI interfaces present in the main part. These additional interfaces do not conflict with existing designs and provide enhanced functionality for future design iterations.

Voltage supply specifications show minor segmentation in the substitute (1.09V ~ 1.21V and 3V ~ 3.6V) compared to the continuous range in the main part (1.09V ~ 3.6V). Both specifications encompass the same operational voltage windows and present no functional incompatibility.

The substitute includes specified Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), providing additional handling and storage guidance not documented for the main part.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components utilize the identical 100-VQFN (12x12) package footprint, operate within compatible voltage ranges (1.09V ~ 3.6V), and support the same core USB 3.1 protocol and I2C/SPI interface requirements. PCB layout and assembly processes require no modification.

Q: What is the primary advantage of selecting the USB7206CT/KDX over the main part?

A: The USB7206CT/KDX is an Active product with substantially higher inventory availability, ensuring reliable supply chain access. The obsolete status of the USB7206T/KDX creates supply constraints and limits long-term production viability.

Q: Are there differences in interface capabilities between these parts?

A: The USB7206CT/KDX provides additional interface protocols (GPIO, I2S, SMBus, USB) beyond the I2C and SPI interfaces of the USB7206T/KDX. Existing designs utilizing only I2C and SPI interfaces experience no functional impact. Additional interfaces remain available for enhanced functionality in redesign scenarios.

Q: How do the voltage supply specifications differ?

A: The USB7206T/KDX specifies a continuous voltage range of 1.09V ~ 3.6V. The USB7206CT/KDX specifies two voltage windows: 1.09V ~ 1.21V and 3V ~ 3.6V. Both specifications encompass the same operational voltage requirements and present no practical incompatibility for standard applications.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it important?

A: The USB7206CT/KDX carries an MSL rating of 3 (168 Hours), indicating the component can remain exposed to ambient conditions for up to 168 hours before soldering without degradation. This specification guides handling, storage, and assembly procedures to prevent moisture-related failures. The main part does not specify an MSL rating.

Q: Are regulatory compliance certifications identical?

A: Yes. Both the USB7206T/KDX and USB7206CT/KDX maintain ROHS3 compliance and REACH Unaffected status, satisfying equivalent environmental and regulatory requirements for component selection and deployment.

Q: What packaging options are available for the USB7206CT/KDX?

A: The USB7206CT/KDX is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly processes. The main part does not specify packaging format details.
