Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB7206-I/KDX is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 100-VQFN (12x12) form factor with exposed pad configuration to ensure mechanical and thermal compatibility on printed circuit boards.

Electrical Specifications: Supply voltage range, operating temperature range, and interface protocols must be compatible with the original design requirements.

Standards Compliance: USB protocol support and regulatory certifications (RoHS3, REACH) must align with the original component specifications.

Functional Capability: The substitute must perform the hub controller function with equivalent or enhanced interface support.

The USB7206C-I/KDX qualifies as a direct substitute based on identical package geometry, overlapping voltage and temperature specifications, maintained compliance certifications, and enhanced interface capabilities that include all protocols supported by the original part.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The USB7206-I/KDX is classified as Obsolete, making the Active-status USB7206C-I/KDX the appropriate selection for new designs and ongoing production support. The substitute part maintains long-term availability through Microchip Technology.

Compliance Alignment: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory requirements are satisfied in either selection. Moisture sensitivity levels are identical, requiring equivalent handling and storage protocols.

Package Compatibility: Identical 100-VQFN (12x12) packaging ensures direct mechanical and thermal compatibility without PCB redesign. Both components feature exposed pad configurations for equivalent thermal management.

Electrical Compatibility: The USB7206C-I/KDX supply voltage range encompasses the original part's specifications, with operating temperature ranges matching exactly. The substitute supports all interface protocols of the original part while adding GPIO, I2S, and SMBus capabilities.

Interface Enhancement: The USB7206C-I/KDX provides expanded interface options (GPIO, I2S, SMBus, USB) beyond the original I2C and SPI support. Designs utilizing only I2C and SPI protocols experience no functional change, while additional interfaces remain available for future application requirements.

Frequently Asked Questions (FAQ)

Q: Can the USB7206C-I/KDX directly replace the USB7206-I/KDX in existing designs?

A: Yes. Both components share identical package geometry (100-VQFN 12x12), matching operating temperature ranges (-40°C to 85°C), overlapping supply voltage specifications, and equivalent compliance certifications. No PCB modifications are required.

Q: What is the primary reason for substitution?

A: The USB7206-I/KDX is Obsolete. The USB7206C-I/KDX maintains Active product status with current manufacturing support from Microchip Technology, ensuring component availability for production and field replacement requirements.

Q: Are there differences in interface protocol support?

A: The original USB7206-I/KDX supports I2C and SPI interfaces. The USB7206C-I/KDX supports I2C, SPI, GPIO, I2S, SMBus, and USB interfaces. Designs using only I2C and SPI experience no functional change. Additional protocols are available but not required for compatibility.

Q: Do moisture sensitivity and handling requirements differ?

A: No. Both components carry MSL 3 (168 Hours) classification, requiring identical moisture control, storage, and handling procedures during manufacturing and assembly.

Q: Are regulatory certifications equivalent?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for deployment in regulated markets and applications.

Q: What is the supply voltage compatibility?

A: The USB7206-I/KDX operates at 1.09V ~ 3.6V. The USB7206C-I/KDX operates at 1.09V ~ 1.21V and 3V ~ 3.6V. The substitute's voltage range encompasses the original specification, ensuring compatible power supply designs.

Q: Is firmware or software modification required for substitution?

A: No firmware or software changes are necessary. Both components function as hardware controllers with identical pin configurations and package geometry. Existing firmware and software implementations operate without modification.
