• Functional Equivalence: Both components serve as USB Hub Controllers with identical protocol and interface specifications
• Interface Standard: USB 3.0 compatibility is maintained across the substitute
• Package Compatibility: Identical 64-VFQFN Exposed Pad package and 64-QFN (9x9) supplier device package ensure PCB-level compatibility
• Electrical Interface: Both operate with compatible supply voltage and current specifications for hub controller applications

The USB5534B-6080JZXTR represents the active production equivalent within the same product family, with enhanced product status and improved moisture sensitivity characteristics.

Parameter Comparison

Engineering Selection Recommendations

The USB5534B-6080JZXTR is the direct active equivalent for the obsolete USB5534-JZX-TR. Selection is based on the following engineering criteria:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity
• Functional Compatibility: Identical hub controller function and USB 3.0 interface specification provide direct functional replacement
• Package Equivalence: Both parts use the same 64-VFQFN Exposed Pad package, enabling direct PCB-level substitution without layout modifications
• Compliance Alignment: Both parts maintain ROHS3 compliance, meeting regulatory requirements for equivalent applications
• Moisture Sensitivity Improvement: The substitute part offers superior moisture sensitivity characteristics (MSL 1 vs. MSL 3), providing enhanced reliability in storage and handling conditions

Frequently Asked Questions (FAQ)

Q: Can the USB5534B-6080JZXTR be used as a direct replacement for the USB5534-JZX-TR?

A: Yes. Both parts share identical functional specifications as USB Hub Controllers with USB 3.0 interface support and are packaged in the same 64-VFQFN Exposed Pad configuration. The substitute part is the active production equivalent within the USB5534 product family.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), specified operating temperature range (not specified vs. 0°C ~ 70°C), supply voltage specifications (not specified vs. 1.25V, 3.3V), moisture sensitivity level (MSL 3 vs. MSL 1), and packaging format (unspecified vs. Tape & Reel). Functionally and electrically, both parts are equivalent for hub controller applications.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 64-VFQFN Exposed Pad package with 64-QFN (9x9) dimensions. PCB layouts designed for the USB5534-JZX-TR require no modification to accommodate the USB5534B-6080JZXTR.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant. The substitute part additionally specifies REACH Unaffected status and EAR99 ECCN classification, providing enhanced regulatory documentation for export and compliance purposes.

Q: What is the significance of the improved moisture sensitivity level?

A: The USB5534B-6080JZXTR carries MSL 1 (Unlimited) compared to MSL 3 (168 Hours) for the original part. This indicates superior moisture resistance and more flexible storage and handling requirements, reducing risk during component procurement, warehousing, and assembly processes.
