Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TUSB7320RKMT are classified based on strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• USB 3.0 protocol compliance
• Host Controller or Hub Controller function
• Supply voltage compatibility (1.1V, 3.3V)
• Operating temperature range (0°C ~ 70°C)
• RoHS3 compliance and MSL 3 rating
• Package compatibility or functional equivalence

Substitute Categories:

Parametric Equivalents (Identical Package & Electrical Specifications):

• TUSB7320RKMR: Identical electrical parameters and 100-WQFN-MR package. Differs only in packaging format (Cut Tape & Digi-Reel vs. original). Fully interchangeable at the component level.
• TUSB7340RKMR: Identical electrical parameters and 100-WQFN-MR package. Differs only in base product number (TUSB7340 vs. TUSB7320). Fully interchangeable at the component level.

Manufacturer Recommended Substitute (Functional Alternative):

• TUSB8020BPHP: Manufacturer-recommended alternative with different functional architecture (Hub Controller vs. Host Controller). Different package format (48-HTQFP vs. 100-WQFN-MR). Maintains USB 3.0 compliance, identical supply voltages, and operating temperature range. Requires PCB redesign due to package change.

Parameter Comparison

Engineering Selection Recommendations

For Direct Component Replacement (No PCB Redesign Required): Select TUSB7320RKMR or TUSB7340RKMR. Both parts maintain identical electrical specifications, operating parameters, and package footprints as the TUSB7320RKMT. These substitutes are fully compatible at the board level and require no circuit modifications. TUSB7320RKMR and TUSB7340RKMR differ only in packaging format and base product designation, with no functional impact on system performance.

For Functional Alternative (PCB Redesign Required): The TUSB8020BPHP is the manufacturer-recommended substitute when component availability is critical. This part maintains USB 3.0 compliance, identical supply voltages, and operating temperature specifications. However, the TUSB8020BPHP is a Hub Controller rather than a Host Controller and uses a 48-HTQFP package instead of the 100-WQFN-MR package. Implementation of this substitute requires PCB layout modifications and potential firmware adjustments to accommodate the different pin configuration and functional architecture.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 3 rating, ensuring compatibility with standard manufacturing and storage protocols. The TUSB8020BPHP holds Active product status, providing extended availability and support compared to the Not For New Designs status of the original and parametric equivalent parts.

Frequently Asked Questions (FAQ)

Q: Can TUSB7320RKMR be used as a direct replacement for TUSB7320RKMT? A: Yes. TUSB7320RKMR is a parametric equivalent with identical electrical specifications, supply voltages, operating temperature range, and package footprint. No circuit modifications are required.

Q: What is the difference between TUSB7320RKMR and TUSB7340RKMR? A: Both parts are parametric equivalents with identical electrical parameters and package specifications. The difference lies in the base product number (TUSB7320 vs. TUSB7340). At the component level, they are functionally interchangeable.

Q: Why would I choose TUSB8020BPHP over the parametric equivalents? A: TUSB8020BPHP is selected when component availability is the primary concern. It maintains USB 3.0 compliance and identical supply voltages but requires PCB redesign due to its different package format (48-HTQFP vs. 100-WQFN-MR) and functional architecture (Hub Controller vs. Host Controller).

Q: Are all substitute parts RoHS3 compliant? A: Yes. TUSB7320RKMT, TUSB7320RKMR, TUSB7340RKMR, and TUSB8020BPHP are all ROHS3 compliant with MSL 3 rating.

Q: What is the operating temperature range for all substitute parts? A: All parts operate within the range of 0°C to 70°C.

Q: Do the parametric equivalents require firmware changes? A: No. TUSB7320RKMR and TUSB7340RKMR are direct replacements with no firmware modifications required.

Q: What interface differences exist between the main part and TUSB8020BPHP? A: TUSB7320RKMT provides USB and PCIe interfaces. TUSB8020BPHP provides USB, GPIO, I2C, and SMBus interfaces. The functional architecture differs between Host Controller and Hub Controller.

Q: Can TUSB8020BPHP be used without PCB modifications? A: No. The different package format (48-HTQFP vs. 100-WQFN-MR) and pin configuration require PCB layout redesign.
