Substitute Part Grouping Explanation

Substitution eligibility for the USB5534B-4100JZXTR is determined by the following critical parameters:

• Manufacturer & Base Product Series: Both parts must originate from Microchip Technology and share the USB5534 base product number to ensure firmware compatibility and pinout alignment.
• Function & Protocol: Both parts must serve as USB Hub Controllers with USB 3.0 protocol support.
• Package Configuration: Both parts must use the 64-VFQFN Exposed Pad package with 64-QFN (9x9) physical dimensions to ensure PCB footprint compatibility.
• Compliance Standards: Both parts must maintain ROHS3 and REACH compliance for regulatory consistency.

The USB5534B-6080JZXTR meets all substitution criteria as a direct equivalent within the USB5534 product family.

Engineering Selection Recommendations

The USB5534B-6080JZXTR is the designated substitute for the obsolete USB5534B-4100JZXTR. Selection of the substitute part is justified on the following grounds:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain identical ROHS3 and REACH compliance certifications, satisfying regulatory requirements without modification.
• Functional Equivalence: Identical hub controller function, USB 3.0 protocol support, and package configuration ensure direct PCB compatibility and firmware interoperability.
• Improved Reliability: The substitute part features MSL 1 (Unlimited) moisture sensitivity compared to MSL 3 (168 Hours), providing enhanced reliability in storage and handling conditions.
• Specified Operating Parameters: The substitute part includes documented voltage supply (1.25V, 3.3V) and operating temperature range (0°C ~ 70°C), enabling precise system design validation.

Frequently Asked Questions (FAQ)

Q: Can the USB5534B-6080JZXTR be used as a direct replacement for the USB5534B-4100JZXTR?

A: Yes. Both parts share identical package configuration (64-VFQFN Exposed Pad, 64-QFN 9x9), function (USB Hub Controller), and USB 3.0 interface standard. PCB footprint and pinout are compatible. The substitute part is the manufacturer-recommended alternative.

Q: What is the difference between the two part numbers?

A: The suffix difference (4100 vs. 6080) indicates variant configuration within the USB5534 product family. Both variants maintain the same core hub controller functionality and package specification. The 6080 variant is currently in active production.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 and REACH compliance status. Regulatory requirements are satisfied by either part without modification.

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

A: The substitute part (MSL 1, Unlimited) has lower moisture sensitivity than the main part (MSL 3, 168 Hours). This indicates improved tolerance to moisture exposure during storage and handling, reducing risk of moisture-induced failures in manufacturing processes.

Q: Is the packaging format (Tape & Reel) a compatibility concern?

A: No. Tape & Reel packaging is a supply format that does not affect component functionality or PCB compatibility. The physical component and electrical characteristics remain identical regardless of packaging format.

Q: Are there any design modifications required when substituting this part?

A: No design modifications are required. The substitute part maintains identical pinout, package footprint, and electrical interface specifications. Direct PCB substitution is supported.
