Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB3290-FH-TR is determined by the following critical parameters:

• Protocol Compatibility: USB 2.0 interface requirement
• Voltage Supply Range: 3V to 3.6V operating range
• Transceiver Configuration: Full-duplex operation capability
• Compliance Standards: ROHS3 compliance and REACH unaffected status
• Moisture Sensitivity: MSL 3 rating for storage and handling

The USB3280-AEZG-TR qualifies as a manufacturer-recommended substitute based on matching voltage supply specifications, ROHS3 compliance, identical MSL rating, and equivalent REACH status. Both components are manufactured by Microchip Technology and share the same base product family designation.

Parameter Comparison

Engineering Selection Recommendations

The USB3280-AEZG-TR is designated as the manufacturer-recommended substitute for the obsolete USB3290-FH-TR. Selection of this substitute is supported by:

• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity
• Product Availability: The USB3280-AEZG-TR maintains active product status with current inventory availability, addressing obsolescence concerns
• Electrical Specifications: Identical voltage supply range (3V to 3.6V) ensures direct electrical compatibility
• Handling Requirements: Matching MSL 3 rating maintains equivalent moisture sensitivity and storage protocols

The primary design consideration is the package transition from 40-VFBGA (4x4) to 36-VFQFN (6x6), which requires PCB layout modification and footprint redesign.

Frequently Asked Questions (FAQ)

Q: Can the USB3280-AEZG-TR be used as a direct pin-for-pin replacement?

A: No. While both components share electrical specifications and voltage requirements, the package formats differ significantly. The USB3290-FH-TR uses 40-VFBGA (4x4) packaging, while the USB3280-AEZG-TR uses 36-VFQFN (6x6) packaging. PCB layout and footprint redesign is required.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both components maintain identical ROHS3 compliance status, REACH unaffected designation, and MSL 3 moisture sensitivity rating. Regulatory requirements remain consistent.

Q: What is the primary reason for substitution?

A: The USB3290-FH-TR is classified as obsolete. The USB3280-AEZG-TR is the manufacturer-recommended active alternative, ensuring continued component availability and supply chain continuity.

Q: Do both parts operate at the same voltage levels?

A: Yes. Both components operate within the identical 3V to 3.6V supply voltage range, ensuring electrical compatibility in power delivery circuits.

Q: What design changes are necessary for implementation?

A: The package transition requires PCB footprint modification from 40-VFBGA to 36-VFQFN format. Pin mapping and signal routing must be verified against the respective datasheets for each component variant.
