Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5816-I/KD is determined by the following critical parameters:

• Functional Equivalence: Hub Controller function with USB 3.1 protocol support
• Interface Compatibility: I2C and SPI interface requirements
• Package Compatibility: 100-VFQFN (12x12) with exposed pad
• Electrical Specifications: Supply voltage ranges and operating temperature
• Compliance Requirements: RoHS3 and REACH compliance status
• Moisture Sensitivity: MSL 3 classification

The USB5816C-I/KD qualifies as a direct substitute based on identical functional classification, protocol support, interface configuration, and package specification. The substitute part maintains the same base product number (USB5816) and is manufactured by the same supplier (Microchip Technology), ensuring design compatibility.

Engineering Selection Recommendations

The USB5816C-I/KD is the recommended substitute for the obsolete USB5816-I/KD. Selection is based on the following engineering criteria:

• Product Status: The substitute part maintains Active status, ensuring continued availability and manufacturing support from Microchip Technology
• Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs
• Functional Compatibility: Identical USB 3.1 hub controller functionality with I2C and SPI interface support ensures direct design compatibility
• Package Specification: Identical 100-VQFN (12x12) package with exposed pad maintains PCB layout and thermal management characteristics
• Electrical Compatibility: The substitute part voltage supply range (1.08V ~ 1.32V, 3V ~ 3.6V) encompasses the main part specification (1.2V, 3.3V), ensuring operational compatibility across the specified temperature range

Frequently Asked Questions (FAQ)

Q: Can USB5816C-I/KD be used as a direct replacement for USB5816-I/KD in existing designs?

A: Yes. The substitute part maintains identical functional classification, protocol support, interface configuration, and package specification. The electrical specifications of the substitute part are compatible with the main part requirements.

Q: Are there any package differences between the main part and substitute?

A: No. Both parts use the 100-VQFN (12x12) package with exposed pad. PCB layout and thermal design considerations remain unchanged.

Q: What is the difference in voltage supply specifications?

A: The main part specifies discrete voltage levels (1.2V, 3.3V), while the substitute part specifies voltage ranges (1.08V ~ 1.32V, 3V ~ 3.6V). The substitute ranges encompass the main part specifications, ensuring compatibility.

Q: Does the substitute part maintain the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance status.

Q: Why is the main part classified as Obsolete?

A: Product obsolescence is determined by the manufacturer. The substitute part, classified as Active, provides continued access to equivalent functionality with ongoing manufacturing support.

Q: Are the interface protocols identical between both parts?

A: Yes. Both parts support I2C and SPI interfaces for USB 3.1 hub controller applications.
