TUSB8042AIRGCT Equivalent & Substitute Parts

Part Overview

The TUSB8042AIRGCT is an active USB Hub Controller manufactured by Texas Instruments, designed for USB 3.1 applications requiring I2C and SMBus interface capabilities. This interface component operates across dual voltage domains (0.99V–1.26V and 3V–3.6V) and is housed in a 64-VQFN package with exposed pad. The device maintains Active product status and full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitute parts for the TUSB8042AIRGCT are qualified based on strict parametric equivalence across the following criteria:

Electrical Equivalence: Identical protocol (USB), function (Hub Controller), interface standards (I2C, SMBus), USB specification compliance (USB 3.1), and dual voltage supply ranges (0.99V–1.26V and 3V–3.6V).

Thermal Equivalence: Matching operating temperature range (−40°C to +85°C).

Mechanical Equivalence: Identical package type (64-VQFN with 9×9mm footprint and exposed pad), ensuring PCB layout compatibility without redesign.

Compliance Equivalence: RoHS3 compliance and identical Moisture Sensitivity Level (MSL 3, 168 Hours) certification.

Product Status: All substitute parts maintain Active status, ensuring continued manufacturing support and supply chain availability.

The TUSB8043AIRGCT and TUSB8044AIRGCT meet all substitution criteria and are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TUSB8042AIRGCT, TUSB8043AIRGCT, and TUSB8044AIRGCT—are functionally equivalent and interchangeable at the circuit level. Selection between them is determined by supply chain availability and packaging format preference:

TUSB8043AIRGCT: Supplied in Cut Tape (CT) and Digi-Reel® format. Appropriate for mixed-volume production and component kit assembly.

TUSB8044AIRGCT: Supplied in Cut Tape (CT) and Digi-Reel® format. Appropriate for mixed-volume production and component kit assembly.

All parts maintain Active product status, ensuring long-term availability and manufacturing continuity. RoHS3 compliance and identical MSL ratings guarantee environmental and reliability standards across all variants.

Frequently Asked Questions (FAQ)

Q: Can TUSB8043AIRGCT or TUSB8044AIRGCT be used as direct replacements for TUSB8042AIRGCT?

A: Yes. All three parts are parametric equivalents with identical electrical specifications, thermal ratings, package dimensions, and compliance certifications. No circuit modifications are required for substitution.

Q: Are there differences in USB 3.1 protocol support between these parts?

A: No. All three parts implement identical USB 3.1 standards and I2C/SMBus interface protocols.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® are packaging and delivery formats only. They do not alter component electrical characteristics or performance.

Q: Are all three parts RoHS3 compliant?

A: Yes. TUSB8042AIRGCT, TUSB8043AIRGCT, and TUSB8044AIRGCT all meet ROHS3 compliance requirements.

Q: What is the significance of MSL 3 (168 Hours) rating?

A: MSL 3 indicates the component can be exposed to moisture for up to 168 hours at specified temperature and humidity conditions before soldering. All three parts share this rating, ensuring identical moisture handling requirements during assembly.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since all three parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably within the same design without functional impact.
