Substitute Part Grouping Explanation

Substitute parts for the TUSB8041RGCR are identified within the Texas Instruments TUSB804x controller family based on the following criteria:

Packaging Compatibility: All substitute parts maintain the 64-VQFN (9x9) Exposed Pad package configuration, ensuring mechanical and thermal compatibility with existing PCB layouts.

Electrical Specifications: Substitute parts operate at identical supply voltages (1.1V, 3.3V) and within the same operating temperature range (0°C ~ 70°C), ensuring functional interchangeability in circuit designs.

Functional Equivalence: All parts provide USB 3.0 hub controller functionality with identical interface support (USB, GPIO, I2C, SMBus), maintaining protocol and communication compatibility.

Compliance & Certification: All substitute parts maintain ROHS3 compliance, identical MSL rating (3, 168 Hours), and equivalent regulatory status (REACH Unaffected, ECCN EAR99).

Packaging Format Variations: Substitutes are available in both Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats, allowing selection based on procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and are ROHS3 compliant with identical regulatory certifications (REACH Unaffected, ECCN EAR99). Selection between TUSB8041RGCR, TUSB8041ARGCT, TUSB8041RGCT, and TUSB8042RGCT is determined by packaging format availability and inventory requirements rather than electrical or functional differences.

For applications requiring Cut Tape & Digi-Reel® format, TUSB8041RGCR and TUSB8041RGCT are functionally equivalent. For Tape & Reel format procurement, TUSB8041ARGCT provides identical electrical and functional specifications. The TUSB8042RGCT variant, while maintaining all core specifications, represents a different base product number within the controller family and is functionally equivalent for USB 3.0 hub controller applications.

Frequently Asked Questions (FAQ)

Q: Are TUSB8041RGCR and TUSB8041RGCT electrically interchangeable?

A: Yes. Both parts operate at identical supply voltages (1.1V, 3.3V), within the same temperature range (0°C ~ 70°C), and provide equivalent USB 3.0 hub controller functionality with identical interface support (USB, GPIO, I2C, SMBus). The primary difference is packaging format: TUSB8041RGCR is supplied in Cut Tape & Digi-Reel®, while TUSB8041RGCT is also available in Cut Tape & Digi-Reel® format.

Q: What is the difference between TUSB8041ARGCT and TUSB8041RGCT?

A: Both parts are electrically and functionally equivalent. The primary distinction is packaging format: TUSB8041ARGCT is supplied in Tape & Reel (TR) format, while TUSB8041RGCT is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly line requirements and procurement specifications.

Q: Can TUSB8042RGCT replace TUSB8041RGCR in existing designs?

A: Yes. TUSB8042RGCT maintains identical electrical specifications, operating parameters, package configuration (64-VQFN 9x9), and functional capabilities as a USB 3.0 hub controller. Both parts support USB, GPIO, I2C, and SMBus interfaces and operate within the same voltage and temperature ranges. The TUSB8042 represents a different base product number within the Texas Instruments controller family but is functionally equivalent for hub controller applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TUSB8041RGCR, TUSB8041ARGCT, TUSB8041RGCT, and TUSB8042RGCT are all ROHS3 compliant with identical MSL rating (3, 168 Hours) and equivalent regulatory status (REACH Unaffected, ECCN EAR99).

Q: What packaging formats are available for these USB hub controller parts?

A: TUSB8041RGCR and TUSB8041RGCT are supplied in Cut Tape (CT) & Digi-Reel® format. TUSB8041ARGCT is supplied in Tape & Reel (TR) format. TUSB8042RGCT is supplied in Cut Tape (CT) & Digi-Reel® format. Selection should align with assembly equipment capabilities and procurement workflows.
