Substitute Part Grouping Explanation

Substitution eligibility for the TUSB7340IRKMR is determined by strict alignment of the following 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 TUSB7340IRKMR has two qualified substitutes: TUSB7320IRKMT and TUSB7340IRKMT. Both parts maintain identical electrical specifications, thermal characteristics, compliance certifications, and physical packaging. The primary distinction between these parts is packaging format: the main part uses standard packaging, while substitutes are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats respectively.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TUSB7340IRKMR, TUSB7320IRKMT, and TUSB7340IRKMT—are classified as Not For New Designs and carry identical electrical, thermal, and compliance specifications. Selection between these parts should be based on:

1. Packaging availability and supply chain requirements: Choose Tape & Reel (TR) format for high-volume automated assembly or Cut Tape (CT) & Digi-Reel® format for lower-volume or mixed-component procurement.

2. Inventory status: TUSB7340IRKMT offers the highest current inventory (65,980 pcs), followed by TUSB7340IRKMR (35,621 pcs) and TUSB7320IRKMT (1,712 pcs).

3. Compliance requirements: All parts maintain ROHS3 compliance and REACH Unaffected status, suitable for regulated applications.

4. Thermal and electrical compatibility: All parts operate within identical voltage ranges (1.1V, 3.3V) and temperature ranges (-40°C ~ 85°C), ensuring direct functional equivalence in circuit design.

Frequently Asked Questions (FAQ)

Q: Can TUSB7320IRKMT and TUSB7340IRKMT be used interchangeably with TUSB7340IRKMR?

A: Yes. All three parts share identical electrical specifications, thermal characteristics, package dimensions (100-WQFN-MR 9x9), and compliance certifications. The only difference is packaging format (standard vs. Tape & Reel vs. Cut Tape & Digi-Reel®), which does not affect circuit-level functionality.

Q: What does "Not For New Designs" status mean?

A: This designation indicates the part has reached end-of-life. Texas Instruments no longer recommends these components for new product development. However, they remain suitable for legacy system repairs, maintenance, and replacement applications.

Q: Are there any differences in electrical performance between these substitutes?

A: No. All three parts maintain identical voltage supply requirements (1.1V, 3.3V), operating temperature range (-40°C ~ 85°C), and USB 3.0 Host Controller functionality with USB and PCIe interface support.

Q: How does packaging format affect part selection?

A: Packaging format determines procurement and assembly logistics. Standard packaging suits individual or small-batch orders. Tape & Reel (TR) format optimizes high-volume automated assembly lines. Cut Tape (CT) & Digi-Reel® format provides flexibility for mixed-component kits and moderate-volume production.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. TUSB7340IRKMR, TUSB7320IRKMT, and TUSB7340IRKMT all carry ROHS3 Compliant status and REACH Unaffected designation, meeting environmental and regulatory requirements for regulated markets.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: All three parts have MSL 3 (168 Hours), indicating they require controlled storage conditions and have a 168-hour floor life after moisture exposure. This specification is identical across all substitutes and does not affect substitution decisions.
