Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5816T-I/KD is determined by the following critical parameters:

• Function & Protocol: Both parts function as USB Hub Controllers supporting USB 3.1 protocol
• Interface Compatibility: I2C and SPI interface support must be maintained
• Package Specification: 100-VQFN (12x12) with exposed pad is required for mechanical and thermal compatibility
• Operating Temperature Range: -40°C ~ 85°C operational envelope must be supported
• Compliance & Certifications: ROHS3 compliance and MSL 3 rating must be maintained
• Supply Voltage Range: Substitute parts must support the required voltage supply specifications

The USB5816CT-I/KD meets all these criteria and is the manufacturer-recommended substitute, with the primary distinction being Active product status and packaging format (Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The USB5816CT-I/KD is the appropriate substitute for the obsolete USB5816T-I/KD based on the following factors:

• Product Status: The substitute maintains Active status, ensuring continued manufacturer support and availability
• Functional Equivalence: Both parts share identical USB 3.1 hub controller functionality with I2C and SPI interface support
• Package Compatibility: Identical 100-VQFN (12x12) package specification ensures direct PCB compatibility
• Compliance Alignment: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings
• Thermal & Operating Specifications: Matching operating temperature range (-40°C ~ 85°C) ensures equivalent performance across environmental conditions
• Supply Voltage Compatibility: The substitute's voltage range (1.08V ~ 1.32V, 3V ~ 3.6V) encompasses the main part's specified voltages (1.2V, 3.3V)

Frequently Asked Questions (FAQ)

Q: Can USB5816CT-I/KD be used as a direct replacement for USB5816T-I/KD?

A: Yes. Both parts are functionally equivalent USB 3.1 hub controllers with identical I2C and SPI interface support, package specification (100-VQFN 12x12), and operating temperature range. The substitute is the manufacturer-recommended alternative.

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

A: The main difference is product status: USB5816T-I/KD is Obsolete, while USB5816CT-I/KD is Active. Additionally, USB5816CT-I/KD is supplied in Tape & Reel packaging format, whereas the original part does not specify packaging format.

Q: Are the supply voltage specifications compatible?

A: Yes. The substitute's supply voltage range (1.08V ~ 1.32V for 1.2V rail, 3V ~ 3.6V for 3.3V rail) fully encompasses the main part's specified voltages, ensuring compatible operation in existing designs.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 3 rating with 168-hour floor life, requiring identical handling and storage protocols.

Q: Is the 100-VQFN package identical between both parts?

A: Yes. Both parts use the 100-VQFN (12x12) package with exposed pad, ensuring mechanical and thermal compatibility on the same PCB layout.

Q: Are there compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, with no compliance-related restrictions on substitution.
