Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5807-I/KD is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 100-VQFN (12x12) package with exposed pad configuration to ensure PCB footprint compatibility and thermal performance equivalence.

Interface Protocol: The USB5807-I/KD implements SPI interface. Substitute parts must support SPI as a minimum interface requirement. Extended interface support (such as I2C in addition to SPI) does not prevent substitution, as SPI functionality remains available.

USB Standard Compliance: Both parts must comply with USB 3.1 standard to maintain protocol compatibility within the system architecture.

Supply Voltage Ranges: The main part operates at 1.2V and 3.3V. Substitute parts must support these voltage levels or overlapping ranges to ensure power delivery compatibility.

Operating Temperature Range: Both parts must support the -40°C ~ 85°C operating temperature range for thermal environment compatibility.

Base Product Number: Both parts share the USB5807 base product number, indicating they are part of the same product family and design lineage.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity ratings to meet manufacturing and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The USB5807C-I/KD is the designated substitute for the obsolete USB5807-I/KD. Both components share identical package geometry, USB 3.1 compliance, operating temperature range, and regulatory certifications. The USB5807C-I/KD maintains full backward compatibility with SPI interface requirements while adding I2C interface capability. Supply voltage ranges are compatible, with the substitute offering slightly extended voltage tolerance windows. The USB5807C-I/KD holds active product status with established supply chain availability, making it the appropriate selection for replacement applications and new designs requiring USB 3.1 hub controller functionality.

Frequently Asked Questions (FAQ)

Q: Can the USB5807C-I/KD directly replace the USB5807-I/KD in existing designs?

A: Yes. Both parts use identical 100-VQFN (12x12) package geometry with exposed pad configuration, ensuring PCB footprint compatibility. The USB5807C-I/KD supports SPI interface operation, maintaining functional equivalence with the original design. Supply voltage ranges are compatible within the specified operating parameters.

Q: What is the difference between the USB5807-I/KD and USB5807C-I/KD?

A: The primary difference is interface capability. The USB5807-I/KD implements SPI interface only, while the USB5807C-I/KD supports both I2C and SPI interfaces. The USB5807C-I/KD also features extended supply voltage tolerance ranges (1.08V ~ 1.32V for core supply, 3V ~ 3.6V for I/O supply) compared to the fixed 1.2V and 3.3V specifications of the original part. The USB5807C-I/KD holds active product status, whereas the USB5807-I/KD is obsolete.

Q: Are there any thermal or electrical performance differences?

A: Both parts operate within the same -40°C ~ 85°C temperature range and maintain identical moisture sensitivity ratings (MSL 3, 168 hours). Package thermal characteristics are equivalent due to identical physical dimensions and exposed pad configuration.

Q: What packaging options are available for the USB5807C-I/KD?

A: The USB5807C-I/KD is supplied in Tray packaging. Both the main part and substitute maintain the 100-VQFN (12x12) package specification with exposed pad.

Q: Are both parts RoHS compliant?

A: Yes. Both the USB5807-I/KD and USB5807C-I/KD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
