TUSB4041IPAPRQ1 Equivalent & Substitute Parts

Part Overview

The TUSB4041IPAPRQ1 is a USB 2.0 4-port hub controller manufactured by Texas Instruments, housed in a 64-HTQFP (10x10) package. This interface IC functions as a hub controller for USB 2.0 applications and maintains active product status with automotive-grade qualification (AEC-Q100). Substitute parts are identified when equivalent electrical specifications and compatible packaging configurations are required for design flexibility, inventory management, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TUSB4041IPAPRQ1 are classified based on the following criteria:

Primary Substitution Criteria:

• Manufacturer: Texas Instruments
• Protocol: USB
• Standards: USB 2.0
• Function: Hub Controller
• Voltage Supply: 1.1V, 3.3V
• Operating Temperature: -40°C ~ 85°C
• Grade: Automotive
• Qualification: AEC-Q100
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Substitute Classification:

Full Equivalent (Same Port Count & Package): TUSB4041IPAPR maintains identical electrical specifications, port configuration (4-port), and package format (64-HTQFP 10x10), differing only in packaging designation (Cut Tape vs. Digi-Reel).

Parametric Equivalent (Reduced Port Count, Different Package): TUSB4020BIPHPRQ1 shares all core electrical parameters, automotive qualification, and compliance standards but provides a 2-port hub controller configuration in a 48-HTQFP (7x7) package. This substitute is applicable when port count reduction is acceptable and board space constraints require a smaller footprint.

Parameter Comparison

Engineering Selection Recommendations

TUSB4041IPAPR: Select this substitute when the design requires identical electrical performance and 4-port hub controller functionality. Both parts maintain active product status, automotive-grade qualification (AEC-Q100), and ROHS3 compliance. The substitution is valid for applications where packaging designation (Cut Tape vs. Digi-Reel) does not impact procurement or assembly processes.

TUSB4020BIPHPRQ1: Select this substitute when design requirements permit reduction from 4-port to 2-port hub controller functionality and when board space constraints necessitate a smaller package footprint (48-HTQFP 7x7 vs. 64-HTQFP 10x10). All core electrical specifications, automotive qualification, and compliance certifications remain equivalent. This substitution requires design validation to confirm that 2-port functionality meets application requirements.

Frequently Asked Questions (FAQ)

Q: Can TUSB4041IPAPR be used as a direct replacement for TUSB4041IPAPRQ1?

A: Yes. Both parts are identical in electrical specifications, port count (4-port), package type (64-HTQFP 10x10), and all compliance certifications. The difference is limited to packaging designation and inventory source.

Q: Is TUSB4020BIPHPRQ1 a direct substitute for TUSB4041IPAPRQ1?

A: TUSB4020BIPHPRQ1 is a parametric equivalent, not a direct substitute. It maintains all electrical specifications and automotive qualifications but provides 2-port functionality instead of 4-port. Design validation is required to confirm that reduced port count is acceptable for the application.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: USB 2.0 protocol compliance, hub controller function, 1.1V/3.3V supply voltage compatibility, -40°C to 85°C operating temperature range, automotive grade classification, AEC-Q100 qualification, ROHS3 compliance, and MSL 3 moisture sensitivity rating.

Q: Are there package compatibility considerations between these parts?

A: Yes. TUSB4041IPAPRQ1 and TUSB4041IPAPR use identical 64-HTQFP (10x10) packages and are pin-compatible. TUSB4020BIPHPRQ1 uses a 48-HTQFP (7x7) package and requires PCB redesign due to different pin count and footprint.

Q: Do all substitute parts maintain automotive qualification?

A: Yes. All listed parts carry automotive-grade classification and AEC-Q100 qualification, meeting automotive industry standards for reliability and quality.
