Key Parameters

Substitute Part Grouping Explanation

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

• USB Standard Compliance: Both parts must support USB 3.1 protocol
• Package Compatibility: Identical 100-VQFN (12x12) form factor with exposed pad
• Interface Protocol: SPI interface is mandatory; I2C support is optional
• Supply Voltage Range: Must accommodate the required voltage levels for system operation
• Operating Temperature Range: Must meet or exceed 0°C ~ 70°C specification
• Regulatory Compliance: RoHS3 and REACH status must be maintained

The USB5807C/KD qualifies as a direct substitute based on these parameters. It maintains identical package geometry, USB 3.1 compliance, and temperature operating range while expanding interface capability to include both I2C and SPI protocols.

Engineering Selection Recommendations

The USB5807C/KD is the manufacturer-recommended substitute for the obsolete USB5807/KD. Selection of this part is supported by the following factors:

• Product Status: The USB5807C/KD maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both ROHS3 and REACH compliance are maintained, meeting current environmental and safety standards
• Package Compatibility: Identical 100-VQFN (12x12) form factor enables direct PCB layout compatibility without redesign
• Electrical Compatibility: Supply voltage ranges are compatible with existing system designs; the USB5807C/KD accommodates the specified voltage levels
• Protocol Support: The USB5807C/KD retains full SPI interface support while adding I2C capability, providing design flexibility without compromising existing functionality

Frequently Asked Questions (FAQ)

Q: Can the USB5807C/KD be used as a direct replacement for the USB5807/KD?

A: Yes. Both parts share identical package geometry (100-VQFN 12x12), USB 3.1 compliance, operating temperature range, and regulatory certifications. The USB5807C/KD is the manufacturer-recommended substitute.

Q: What is the primary difference between these two parts?

A: The USB5807C/KD adds I2C interface capability in addition to SPI support. The original USB5807/KD supports SPI only. Both maintain full USB 3.1 hub controller functionality.

Q: Are there supply voltage compatibility concerns?

A: No. The USB5807C/KD supply voltage ranges (1.08V ~ 1.32V, 3V ~ 3.6V) encompass the USB5807/KD specifications (1.2V, 3.3V). Systems designed for the original part will operate within the substitute's voltage envelope.

Q: Does the USB5807C/KD require PCB layout modifications?

A: No. Identical package specifications eliminate the need for PCB redesign. Pin-to-pin compatibility is maintained.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL 3 (168 Hours) classification, requiring identical storage and handling procedures.

Q: What is the inventory status of these parts?

A: The USB5807/KD (obsolete) has 2400 units in stock. The USB5807C/KD (active) has 1205 units in stock.
