Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB5533B-5000JZX is determined by the following critical parameters:

• Functional Equivalence: Hub controller function with USB 3.0 protocol support
• Package Compatibility: 64-VFQFN Exposed Pad format with 9x9mm dimensions
• Electrical Specifications: Dual supply voltage support (1.25V, 3.3V)
• Interface Protocol: USB 3.0 standard compliance
• Compliance Requirements: ROHS3 compliance and MSL Level 1 rating

The substitute part USB5533B-6080JZX meets all these criteria. Both parts share the same base product number (USB5533), manufacturer (Microchip Technology), package format, electrical supply requirements, and compliance certifications. The primary distinction lies in product status and operating temperature range specifications.

Parameter Comparison

Engineering Selection Recommendations

The USB5533B-6080JZX serves as the direct functional equivalent to the obsolete USB5533B-5000JZX. Both components maintain identical electrical specifications, package geometry, and compliance certifications. The substitute part carries active product status from Microchip Technology, ensuring continued availability and manufacturing support.

Selection of USB5533B-6080JZX is appropriate for applications where the operating temperature requirement does not exceed 70°C. For systems requiring operation across the full 0°C to 85°C range, thermal performance validation against the reduced upper temperature limit of the substitute part is necessary.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, supporting standard handling and storage protocols without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can USB5533B-6080JZX directly replace USB5533B-5000JZX in existing designs?

A: Yes, provided the application operating temperature does not exceed 70°C. Both parts share identical package geometry, electrical supply requirements, and USB 3.0 interface specifications. Pinout and functional behavior are equivalent.

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

A: The USB5533B-6080JZX has a reduced maximum operating temperature of 70°C compared to the USB5533B-5000JZX at 85°C. The substitute part also carries active product status, ensuring ongoing availability from Microchip Technology.

Q: Are there any compliance or handling differences?

A: No. Both parts maintain identical ROHS3 compliance status and MSL Level 1 moisture sensitivity rating. Standard component handling and storage procedures apply equally to both variants.

Q: Does the packaging format affect electrical performance?

A: No. The USB5533B-5000JZX is supplied in bulk packaging while USB5533B-6080JZX is supplied in tray packaging. This distinction affects logistics and handling only; electrical and functional characteristics remain unchanged.

Q: What should be verified before implementing the substitute part?

A: Confirm that the application's maximum operating temperature requirement does not exceed 70°C. Verify PCB layout compatibility with the 64-QFN (9x9) package format and exposed pad thermal management requirements.
