Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB7056T/KDX is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the identical 100-VFQFN Exposed Pad package (100-VQFN 12x12 footprint) to ensure PCB-level compatibility without redesign.

Functional Classification: The substitute must serve as a USB hub controller with GPIO interface capability, maintaining the core hub controller function.

Manufacturer Consistency: Parts sourced from Microchip Technology ensure design continuity and support ecosystem alignment.

Compliance Standards: RoHS3 compliance and identical moisture sensitivity level (MSL 3, 168 Hours) are required to maintain manufacturing and storage process compatibility.

USB Protocol Support: The substitute must support USB 3.x generation standards to maintain high-speed data transfer capability.

The USB7016T/KDX meets all substitution criteria and is identified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The USB7016T/KDX is the manufacturer-recommended substitute for the obsolete USB7056T/KDX. Both components share identical physical packaging (100-VQFN 12x12), compliance certifications (ROHS3, MSL 3), and core hub controller functionality.

The USB7016T/KDX offers the advantage of active product status, ensuring continued availability and manufacturing support. The substitute extends USB protocol support to include USB 3.2 alongside USB 2.0, providing enhanced backward and forward compatibility. Both parts maintain GPIO interface capability essential for system integration.

The USB7016T/KDX includes automotive-grade qualification (AEC-Q100) and specified operating parameters (0°C ~ 70°C, dual supply voltage ranges), which may exceed requirements for non-automotive applications but provide additional design margin and reliability assurance.

Frequently Asked Questions (FAQ)

Q: Can the USB7016T/KDX directly replace the USB7056T/KDX without PCB modification?

A: Yes. Both components use the identical 100-VQFN (12x12) package with exposed pad. No PCB redesign is required for physical substitution.

Q: What interface protocols are supported by the USB7016T/KDX?

A: The USB7016T/KDX supports GPIO, I2C, SPI, and USB interfaces. The original USB7056T/KDX includes I2S and UART protocols not present in the substitute. System designs relying on I2S or UART functionality require alternative solutions.

Q: Is the USB7016T/KDX suitable for automotive applications?

A: The USB7016T/KDX carries automotive-grade qualification (AEC-Q100) and is rated for 0°C ~ 70°C operating temperature. The original USB7056T/KDX does not specify automotive qualification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the USB7056T/KDX and USB7016T/KDX are ROHS3 compliant with identical moisture sensitivity level (MSL 3, 168 Hours).

Q: What USB protocol versions does each part support?

A: The USB7056T/KDX supports USB 3.1 Gen1. The USB7016T/KDX supports USB 2.0 and USB 3.2, providing broader protocol compatibility.

Q: Are there supply voltage specifications for the USB7056T/KDX?

A: Supply voltage specifications are not provided for the USB7056T/KDX. The USB7016T/KDX specifies dual supply ranges: 1.08V ~ 1.32V and 3V ~ 3.6V.
