Substitute Part Grouping Explanation

The USB7050PT-I/KDX qualifies as a manufacturer-recommended substitute for the USB7050T-I/KDX based on the following substitution criteria:

Functional Equivalence: Both parts are USB hub controller devices manufactured by Microchip Technology within the same product family (base product number USB7050). Both support multi-port USB connectivity with Power Delivery upstream functionality.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory consistency in applications requiring these certifications.

Environmental Specifications: Both parts share identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), indicating equivalent handling and storage requirements.

Key Differentiators: The primary distinction is the upgrade from USB 3.1 Gen1 to USB 3.2 Gen1 protocol support in the substitute part, representing a generational advancement while maintaining backward compatibility. The substitute part transitions from Cut Tape packaging to Tape & Reel (TR) packaging and shifts from Obsolete to Active product status.

Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Mitigation: The USB7050PT-I/KDX is the manufacturer-recommended substitute and should be prioritized for new designs and production transitions. Its Active product status ensures long-term availability and supply chain stability compared to the Obsolete USB7050T-I/KDX.

For Compliance Requirements: Both parts satisfy ROHS3 and REACH requirements. The USB7050PT-I/KDX additionally carries Automotive grade qualification and AEC-Q100 certification, making it suitable for automotive and mission-critical applications requiring enhanced reliability standards.

For Packaging Considerations: The transition from Cut Tape to Tape & Reel packaging in the substitute part aligns with standard high-volume manufacturing practices and automated assembly processes.

For Protocol Requirements: The USB7050PT-I/KDX supports USB 3.2 Gen1, providing forward compatibility while maintaining USB 2.0 backward compatibility. This represents a generational improvement over USB 3.1 Gen1 without introducing functional incompatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are from the same manufacturer product family and share core hub controller functionality with identical compliance ratings (ROHS3, REACH Unaffected) and MSL specifications. The USB7050PT-I/KDX represents a generational upgrade with Active product status, making it the recommended replacement path.

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

A: The USB7050T-I/KDX supports USB 3.1 Gen1 protocol, while the USB7050PT-I/KDX supports USB 3.2 Gen1 and USB 2.0. USB 3.2 Gen1 is a generational advancement that maintains backward compatibility with USB 3.1 Gen1 specifications.

Q: Are there packaging implications for switching to the substitute part?

A: Yes. The USB7050T-I/KDX uses Cut Tape (CT) & Digi-Reel® packaging, while the USB7050PT-I/KDX uses standard Tape & Reel (TR) packaging. This transition aligns with automated assembly processes and does not affect electrical performance or pin compatibility.

Q: Does the USB7050PT-I/KDX meet automotive qualification requirements?

A: Yes. The USB7050PT-I/KDX carries Automotive grade classification and AEC-Q100 qualification, making it suitable for automotive applications. The original USB7050T-I/KDX does not specify automotive qualification.

Q: Why is the USB7050T-I/KDX classified as Obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued active production and support. The USB7050PT-I/KDX, with Active status, represents the current production equivalent and should be used for new designs and ongoing production requirements.

Q: Are the environmental handling requirements identical?

A: Yes. Both parts share MSL 3 (168 Hours) ratings, indicating identical moisture sensitivity levels and storage/handling requirements during manufacturing and assembly processes.
