Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB5916/KD is determined by the following critical parameters:

• Package Compatibility: Identical 100-VQFN (12x12) form factor with exposed pad
• Functional Classification: Hub Controller function within USB protocol family
• Interface Support: Minimum requirement of I2C and SPI interfaces
• USB Standards Support: USB 3.1 capability
• Supply Voltage Compatibility: Operating voltage ranges that encompass or align with 1.2V and 3.3V requirements
• Operating Temperature Range: 0°C ~ 70°C specification
• Compliance Standards: ROHS3 compliance and MSL rating of 3

The USB5916C/KD qualifies as a direct substitute based on these parameters. It maintains identical package geometry, supports the required USB 3.1 standard, includes I2C and SPI interfaces, operates within the specified temperature range, and meets all compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The USB5916C/KD is the manufacturer-recommended substitute for the obsolete USB5916/KD. Both components share identical package specifications, thermal operating ranges, and compliance certifications. The USB5916C/KD maintains active product status, ensuring continued availability and manufacturing support. The substitute part extends interface capability through the addition of SMBus and UART protocols while retaining full I2C and SPI compatibility. Supply voltage specifications are refined in the USB5916C/KD (1.08V ~ 1.32V and 3V ~ 3.6V) compared to the discrete 1.2V and 3.3V of the original part, providing enhanced operational flexibility within standard industrial voltage tolerances.

Frequently Asked Questions (FAQ)

Q: Can the USB5916C/KD directly replace the USB5916/KD in existing designs?

A: Yes. Both parts utilize the identical 100-VQFN (12x12) package with exposed pad, operate within the same temperature range (0°C ~ 70°C), and support USB 3.1 with I2C and SPI interfaces. The USB5916C/KD is the manufacturer-designated substitute.

Q: What are the key differences between USB5916/KD and USB5916C/KD?

A: The USB5916C/KD adds USB 2.0 standard support alongside USB 3.1, includes SMBus and UART interface options in addition to I2C and SPI, and specifies refined supply voltage ranges. The original USB5916/KD is obsolete; the USB5916C/KD maintains active production status.

Q: Are there packaging differences between these parts?

A: No. Both components use the 100-VQFN (12x12) package format with exposed pad. The USB5916C/KD is supplied in Tray packaging, while the USB5916/KD packaging specification was not detailed in the original documentation.

Q: Do compliance certifications remain consistent?

A: Yes. Both parts maintain ROHS3 compliance, identical Moisture Sensitivity Level (MSL) rating of 3 with 168-hour specification, and equivalent REACH and ECCN classifications.

Q: What supply voltage should be used with the USB5916C/KD?

A: The USB5916C/KD operates with dual supply voltages: 1.08V ~ 1.32V and 3V ~ 3.6V. These ranges encompass the original part's 1.2V and 3.3V specifications, ensuring compatibility with existing power delivery designs.
