Substitute Part Grouping Explanation

Substitute parts for the TUSB7320IRKMT are determined by strict equivalence across the following critical parameters:

• Function: Host Controller
• Protocol: USB
• Interface Type: USB, PCIe
• Standards: USB 3.0
• Package / Case: 100-WQFN Dual Rows, Exposed Pad
• Supplier Device Package: 100-WQFN-MR (9x9)
• Voltage - Supply: 1.1V, 3.3V
• Operating Temperature: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The TUSB7340IRKMT and TUSB7340IRKMR are parametric equivalents that maintain identical electrical and mechanical specifications. The primary distinction between substitute parts is packaging format: TUSB7340IRKMT is supplied in Cut Tape (CT) & Digi-Reel® format, while TUSB7340IRKMR is supplied in standard Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TUSB7320IRKMT, TUSB7340IRKMT, and TUSB7340IRKMR—share identical electrical and mechanical specifications, making them functionally interchangeable at the circuit level. Selection between these parts should be based on:

Packaging availability and supply chain requirements. TUSB7340IRKMT and TUSB7340IRKMR offer higher inventory levels (65,980 and 35,621 units respectively) compared to TUSB7320IRKMT (1,712 units), providing greater availability for procurement.

Packaging format preference. Choose TUSB7340IRKMT for Cut Tape (CT) & Digi-Reel® format or TUSB7340IRKMR for standard Tape & Reel (TR) format based on assembly line requirements.

All parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity specifications, ensuring regulatory and environmental consistency across substitutions.

Frequently Asked Questions (FAQ)

Q: Are TUSB7340IRKMT and TUSB7340IRKMR electrically identical to TUSB7320IRKMT?

A: Yes. All three parts share identical electrical specifications including USB 3.0 protocol support, USB and PCIe interface types, supply voltage requirements (1.1V, 3.3V), and operating temperature range (-40°C ~ 85°C).

Q: What is the difference between TUSB7340IRKMT and TUSB7340IRKMR?

A: The primary difference is packaging format. TUSB7340IRKMT is supplied in Cut Tape (CT) & Digi-Reel® format, while TUSB7340IRKMR is supplied in standard Tape & Reel (TR) format. Both contain identical die and electrical performance.

Q: Can I use TUSB7340 series parts as direct replacements in existing TUSB7320IRKMT designs?

A: Yes. The 100-WQFN-MR (9x9) package, pinout, and electrical specifications are identical, enabling direct PCB-level substitution without design modification.

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

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and HTSUS code (8542.39.0001).

Q: Why is TUSB7320IRKMT marked as Not For New Designs?

A: This designation indicates the part has reached end-of-life status. TUSB7340 series parts are recommended for new designs requiring equivalent USB 3.0 host controller functionality.

Q: What is the moisture sensitivity level, and why does it matter?

A: All parts carry MSL 3 (168 Hours), indicating they can be exposed to ambient conditions for up to 168 hours before soldering. Proper storage and handling procedures must be followed to maintain component reliability.
