Engineering Selection Recommendations

All three parts—TUSB7340IRKMT, TUSB7320IRKMT, and TUSB7340IRKMR—share identical electrical and thermal specifications, making them functionally equivalent for USB 3.0 host controller applications. Selection between these parts should be based on:

Packaging Availability: TUSB7340IRKMT is supplied in Cut Tape (CT) & Digi-Reel® format, while TUSB7320IRKMT is supplied in Tape & Reel (TR) format. TUSB7340IRKMR packaging type is not specified. Choose based on your assembly process requirements and inventory management practices.

Product Status Consideration: All three parts carry "Not For New Designs" status from Texas Instruments. For new product development, consult Texas Instruments' current product portfolio for actively supported alternatives. For legacy system maintenance and ongoing production of existing designs, these parts remain electrically and mechanically valid.

Compliance Requirements: All parts maintain ROHS3 compliance and REACH Unaffected status, suitable for applications requiring environmental and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can TUSB7320IRKMT replace TUSB7340IRKMT in existing designs?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications: USB 3.0 host controller function, 100-WQFN-MR (9x9) package, 1.1V/3.3V supply voltage, and -40°C to 85°C operating temperature range. The primary difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®).

Q: What is the difference between TUSB7340IRKMT and TUSB7340IRKMR?

A: Both are TUSB7340 base products with identical electrical specifications and package dimensions. The difference lies in packaging type and supplier designation. TUSB7340IRKMR packaging is not specified in available data. Verify packaging requirements with your supply chain before substitution.

Q: Are these parts suitable for new product designs?

A: All three parts carry "Not For New Designs" status. While they remain electrically functional and compliant, Texas Instruments has superseded these components. For new designs, contact Texas Instruments to identify current-generation USB 3.0 host controller alternatives.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. TUSB7340IRKMT, TUSB7320IRKMT, and TUSB7340IRKMR all maintain ROHS3 compliance and REACH Unaffected status, meeting equivalent environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have MSL 3 with a 168-hour floor life. Observe standard MSL 3 handling procedures: store in dry conditions, limit exposure to ambient humidity, and follow reflow soldering guidelines to prevent moisture-induced defects.

Q: Can I mix packaging formats in the same production run?

A: Packaging format differences (Cut Tape & Digi-Reel® vs. Tape & Reel) affect assembly automation compatibility and inventory management but do not affect electrical performance. Verify your assembly equipment specifications before mixing packaging formats.
