Substitute Part Grouping Explanation

Substitution of the USB5533B-5000JZXTR is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Series: Both parts must originate from Microchip Technology and share the USB5533 base product number to ensure functional and electrical compatibility.
• Functional Classification: Both parts must serve as USB Hub Controllers with identical protocol and interface specifications.
• USB Standard Compliance: Both parts must support USB 3.0 standard to maintain system-level compatibility.
• Package Specification: Both parts must use 64-VFQFN Exposed Pad packaging in 64-QFN (9x9) form factor to ensure mechanical and thermal compatibility with existing PCB layouts.
• Supply Voltage Requirements: Both parts must support the same dual supply voltages (1.25V and 3.3V) for direct electrical substitution.
• Regulatory Compliance: Both parts must maintain ROHS3 compliance and identical moisture sensitivity classification.

The USB5533B-6080JZXTR meets all substitution criteria and is classified as an active product, making it a valid equivalent for the obsolete USB5533B-5000JZXTR.

Parameter Comparison

Engineering Selection Recommendations

The USB5533B-6080JZXTR is the designated equivalent for the obsolete USB5533B-5000JZXTR. Selection of this substitute is based on the following engineering factors:

• Product Status Alignment: The substitute part maintains active product status with Microchip Technology, ensuring continued availability and manufacturing support.
• Functional Equivalence: Both parts share identical USB Hub Controller functionality and USB 3.0 protocol support, enabling direct functional replacement.
• Electrical Compatibility: Matching supply voltage specifications (1.25V and 3.3V) and identical package configuration ensure electrical compatibility without circuit modification.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, satisfying regulatory and environmental requirements.
• Thermal Consideration: The substitute part operates within a narrower temperature range (0°C ~ 70°C) compared to the main part (0°C ~ 85°C). Applications requiring operation above 70°C must be evaluated against actual system thermal requirements.
• Packaging Format: The substitute is supplied in Tape & Reel format, which is standard for production environments and supports automated assembly processes.
