Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB7056-I/KDX is determined by the following critical parameters:

• Package Compatibility: Identical 100-VQFN (12x12) form factor with exposed pad
• Functional Category: USB Hub Controller classification
• Interface Support: GPIO, I2C, and SPI interfaces (core control interfaces)
• USB Protocol Support: USB 3.x generation standards
• Compliance Standards: ROHS3 compliance and EAR99 ECCN classification

The USB7016-I/KDX qualifies as a substitute based on matching package geometry, hub controller function, and core interface support. While the USB7016-I/KDX operates under USB 2.0 and USB 3.2 standards rather than USB 3.1, it maintains the same physical footprint and primary control interface architecture necessary for PCB-level integration.

Parameter Comparison

Engineering Selection Recommendations

The USB7016-I/KDX is the designated substitute for the obsolete USB7056-I/KDX based on the following engineering criteria:

Product Status Alignment: The USB7016-I/KDX maintains active product status with ongoing manufacturer support, ensuring long-term availability and supply chain stability compared to the obsolete USB7056-I/KDX.

Compliance and Certification: Both components meet ROHS3 compliance requirements. The USB7016-I/KDX carries AEC-Q100 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Packaging and Physical Integration: Identical 100-VQFN (12x12) package geometry ensures direct PCB footprint compatibility without layout redesign.

Interface Capability: The USB7016-I/KDX retains GPIO, I2C, and SPI interfaces, which are the primary control interfaces for hub controller operation. The absence of I2S and UART in the substitute requires verification against specific application requirements.

Moisture Sensitivity: The USB7016-I/KDX features MSL 1 (Unlimited) rating, providing superior moisture tolerance compared to the USB7056-I/KDX MSL 3 (168 Hours) rating.

Frequently Asked Questions (FAQ)

Q: Can the USB7016-I/KDX directly replace the USB7056-I/KDX without PCB modifications?

A: Yes, the identical 100-VQFN (12x12) package geometry permits direct footprint substitution without PCB layout changes. Pin-level compatibility must be verified against application schematics.

Q: What are the key interface differences between these components?

A: The USB7056-I/KDX includes I2S and UART interfaces, while the USB7016-I/KDX omits these in favor of USB interface support. Core control interfaces (GPIO, I2C, SPI) are present in both components.

Q: Does the USB 3.2 standard in the USB7016-I/KDX provide backward compatibility with USB 3.1 applications?

A: USB 3.2 maintains backward compatibility with USB 3.1 Gen1 protocol specifications. Application-specific performance requirements must be evaluated independently.

Q: What is the significance of the MSL rating difference?

A: The USB7016-I/KDX MSL 1 (Unlimited) rating indicates superior moisture resistance compared to the USB7056-I/KDX MSL 3 (168 Hours). This affects storage conditions and reflow processing windows during manufacturing.

Q: Is the USB7016-I/KDX suitable for automotive applications?

A: The USB7016-I/KDX carries AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. The USB7056-I/KDX qualification status is not specified.

Q: What supply voltage specifications apply to the USB7016-I/KDX?

A: The USB7016-I/KDX operates at 1.08V ~ 1.32V and 3V ~ 3.6V supply ranges with operating temperature range of -40°C ~ 85°C (TA). Specific application voltage requirements must be verified against design specifications.
