Functional Equivalence: Both parts share identical base product number (USB5534), function (Hub Controller), protocol (USB), and interface standard (USB 3.0).

Package Compatibility: Both components utilize the same package type (64-VFQFN Exposed Pad) and supplier device package specification (64-QFN 9x9), ensuring mechanical and electrical pin compatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent environmental and regulatory requirements.

Supply Chain Status: The USB5534B-6080JZX transitions from obsolete to active product status, providing sustained manufacturing availability and supply continuity.

Parameter Comparison

Engineering Selection Recommendations

The USB5534B-6080JZX is the appropriate selection for new designs and component replacement applications. The transition from obsolete to active status ensures continued manufacturing support, documented supply availability, and compliance with current regulatory frameworks. Both parts maintain equivalent ROHS3 and REACH compliance certifications, satisfying environmental and regulatory requirements for industrial and commercial applications.

The USB5534B-6080JZX provides specified operating parameters (1.25V and 3.3V supply voltage, 0°C to 70°C operating temperature range) that enable precise system design validation. The increased moisture sensitivity level (MSL 3) requires appropriate handling protocols during storage and assembly but does not affect functional equivalence or electrical performance.

Frequently Asked Questions (FAQ)

Q: Are USB5534-JZX and USB5534B-6080JZX pin-compatible?

A: Yes. Both components use the 64-VFQFN Exposed Pad package with 64-QFN (9x9) supplier device package specification, ensuring identical pinout and mechanical compatibility.

Q: What is the primary reason for substitution?

A: The USB5534-JZX is classified as obsolete. The USB5534B-6080JZX is the active equivalent, providing sustained manufacturing availability and supply chain continuity.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and regulatory requirements.

Q: What is the difference in moisture sensitivity level?

A: The USB5534-JZX has MSL 1 (unlimited moisture exposure tolerance), while the USB5534B-6080JZX has MSL 3 (168-hour moisture exposure limit). MSL 3 requires controlled storage conditions and handling protocols during assembly but does not affect electrical performance or functional equivalence.

Q: Are the supply voltage specifications identical?

A: The USB5534-JZX does not specify supply voltage parameters. The USB5534B-6080JZX specifies 1.25V and 3.3V supply voltage operation. Verify your system design operates within these specified voltage ranges.

Q: Can I use USB5534B-6080JZX in existing designs originally specified for USB5534-JZX?

A: Yes, provided your system design operates within the specified parameters of the USB5534B-6080JZX (1.25V and 3.3V supply voltage, 0°C to 70°C operating temperature). The identical package and pinout ensure direct substitution.
