Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB7050T/KDX is determined by the following critical parameters:

• Hub Controller Function: Multi-port USB hub controller capability
• USB Protocol Support: USB 3.x generation compatibility
• Power Delivery: Upstream PD support
• Package Type: 100-pin VQFN form factor
• Regulatory Compliance: ROHS3 and REACH compliance status
• Moisture Sensitivity: MSL 3 rating

The USB7050PT/KDX qualifies as a direct substitute based on these parameters. While the substitute part supports USB 3.2 Gen1 (an advancement over USB 3.1 Gen1), it maintains functional compatibility with the original specification and operates within the same electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The USB7050PT/KDX is the manufacturer-recommended substitute for the obsolete USB7050T/KDX. Both components maintain identical packaging specifications (100-VQFN 12x12), regulatory compliance (ROHS3, REACH), and moisture sensitivity ratings (MSL 3). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The USB7050PT/KDX supports USB 3.2 Gen1, which is backward compatible with USB 3.1 Gen1 applications. Both parts are manufactured by Microchip Technology and share the same base product architecture, minimizing design integration risk.

Frequently Asked Questions (FAQ)

Q: Can the USB7050PT/KDX directly replace the USB7050T/KDX in existing designs?

A: Yes. Both parts use identical 100-VQFN (12x12) packaging and share the same pinout and functional architecture. The substitute part supports USB 3.2 Gen1, which is compatible with USB 3.1 Gen1 specifications.

Q: What is the primary reason for substitution?

A: The USB7050T/KDX is classified as obsolete. The USB7050PT/KDX is the active production equivalent from the same manufacturer.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both maintain MSL 3 moisture sensitivity ratings. The substitute part carries AEC-Q100 automotive qualification, which is an additional qualification not specified for the original part.

Q: What are the packaging considerations?

A: Both parts are supplied in Tape & Reel (TR) format with identical 100-VQFN (12x12) package specifications. No PCB layout modifications are required for substitution.

Q: Is the USB 3.2 Gen1 support in the substitute part a concern for USB 3.1 Gen1 applications?

A: No. USB 3.2 Gen1 is backward compatible with USB 3.1 Gen1. The substitute part will operate correctly in applications designed for the original USB 3.1 Gen1 specification.
