Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TUSB8044ARGCT is determined by strict alignment across the following critical parameters:

• Manufacturer: Texas Instruments (all substitutes from same manufacturer)
• Function: Hub Controller for USB 3.1 applications
• Protocol & Interface: USB with I2C and SMBus support
• Electrical Specifications: Dual voltage supply ranges (0.99V ~ 1.26V and 3V ~ 3.6V)
• Operating Temperature Range: 0°C ~ 70°C (TA)
• Package Configuration: 64-VQFN (9x9) with exposed pad
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 3

The identified substitutes maintain identical electrical characteristics, interface protocols, and package specifications. Differences exist only in base product numbering (TUSB8042, TUSB8043, TUSB8044) and packaging format (Tape & Reel versus Cut Tape & Digi-Reel).

Parameter Comparison

Engineering Selection Recommendations

All identified substitutes maintain full electrical and mechanical compatibility with the TUSB8044ARGCT. Selection criteria are based on the following factors:

Product Status & Compliance: All substitutes are in active production status with identical RoHS3 compliance, REACH unaffected status, and MSL 3 moisture sensitivity ratings. No compliance trade-offs exist between the main part and substitutes.

Packaging Format Consideration: TUSB8044ARGCR differs only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). This variant offers significantly higher inventory availability (48,425 units) and is suitable for applications where packaging format does not impose design or assembly constraints.

Base Product Variants: TUSB8042ARGCT and TUSB8043ARGCT represent alternative base product numbers within the same functional family. These maintain identical electrical specifications and package configurations, with varying inventory levels (1596 and 1991 units respectively).

Supply Chain Flexibility: The availability of multiple substitutes across different base product numbers and packaging formats provides design flexibility for managing supply chain disruptions or production scheduling requirements.

Frequently Asked Questions (FAQ)

Q: Can TUSB8044ARGCR be used as a direct replacement for TUSB8044ARGCT?

A: Yes. TUSB8044ARGCR is electrically and mechanically identical to TUSB8044ARGCT. The only difference is packaging format: TUSB8044ARGCR uses Cut Tape & Digi-Reel® packaging while TUSB8044ARGCT uses Tape & Reel. Both are suitable for PCB assembly applications where the packaging format is compatible with your production equipment.

Q: What is the difference between TUSB8044ARGCT, TUSB8042ARGCT, and TUSB8043ARGCT?

A: These parts share identical electrical specifications, interface protocols (USB 3.1 with I2C and SMBus), voltage supply ranges, operating temperature, and package configuration (64-VQFN 9x9). The differences are in base product numbering only. All three are functionally equivalent USB Hub Controllers suitable for the same applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes, including TUSB8044ARGCT, TUSB8042ARGCT, TUSB8043ARGCT, and TUSB8044ARGCR, are ROHS3 compliant and REACH unaffected. No compliance differences exist between these parts.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects only handling, storage, and assembly logistics. Electrical performance and specifications remain identical across all packaging variants.

Q: Which substitute has the best inventory availability?

A: TUSB8044ARGCR offers the highest inventory availability at 48,425 units. This variant uses Cut Tape & Digi-Reel® packaging and is electrically identical to TUSB8044ARGCT.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All substitutes use the identical 64-VQFN (9x9) package with exposed pad. Pin configurations, electrical characteristics, and interface protocols are identical, allowing direct substitution without PCB redesign.
