TUSB2046BIVFR USB Hub Controller Equivalent & Substitute Parts

Part Overview

The TUSB2046BIVFR is a USB 2.0 hub controller IC manufactured by Texas Instruments, housed in a 32-LQFP (7x7) package. This component functions as a hub controller for USB interface applications requiring USB 2.0 protocol compliance. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility through equivalent electrical specifications and package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TUSB2046BIVFR are identified based on the following criteria:

Primary Substitution Criteria:

• Manufacturer: Texas Instruments (same manufacturer ensures design continuity)
• Function: Hub Controller (identical functional role)
• Protocol & Standards: USB 2.0 (same communication standard)
• Electrical Compatibility: Supply voltage range and current specifications must support the application
• Package Compatibility: Physical form factor must accommodate PCB layout constraints
• Compliance: RoHS3 and REACH status must match or exceed the original specification

Substitution Logic: Two substitute parts are identified. The TUSB2046BVFR represents a direct package-compatible alternative with identical electrical parameters but active product status. The TUSB4041IPAPR offers functional equivalence as a USB 2.0 hub controller but requires evaluation for package and thermal operating range differences.

Engineering Selection Recommendations

TUSB2046BVFR is the primary recommended substitute for TUSB2046BIVFR applications. This part maintains identical electrical specifications (3V ~ 3.6V supply, 40mA current), package form factor (32-LQFP 7x7), and compliance certifications (ROHS3, REACH Unaffected). The primary distinction is product status: TUSB2046BVFR is active and available in production quantities, whereas TUSB2046BIVFR is obsolete. This substitute requires no design modifications and provides direct pin-for-pin compatibility.

TUSB4041IPAPR is a functional alternative for applications where package size constraints permit a larger footprint. This part operates across an extended temperature range (-40°C ~ 85°C, matching the original specification) and supports the same USB 2.0 protocol. However, the 64-HTQFP (10x10) package represents a significant physical change from the 32-LQFP form factor, requiring PCB layout redesign. The supply voltage specification (1.1V, 3.3V) differs from the original 3V ~ 3.6V range and must be evaluated against application power delivery architecture.

Both substitutes maintain ROHS3 compliance and MSL 3 moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can TUSB2046BVFR be used as a direct replacement for TUSB2046BIVFR?

A: Yes. TUSB2046BVFR provides direct substitution with identical electrical parameters (3V ~ 3.6V supply voltage, 40mA current), package configuration (32-LQFP 7x7), and functional specifications. No design modifications are required. The primary difference is product status: TUSB2046BVFR is active and available, while TUSB2046BIVFR is obsolete.

Q: What are the key differences between TUSB2046BVFR and TUSB4041IPAPR?

A: Both are USB 2.0 hub controllers from Texas Instruments, but they differ in package size and operating temperature range. TUSB2046BVFR uses a 32-LQFP (7x7) package with 0°C ~ 70°C operating range. TUSB4041IPAPR uses a larger 64-HTQFP (10x10) package with -40°C ~ 85°C operating range. The supply voltage specifications also differ: TUSB2046BVFR requires 3V ~ 3.6V, while TUSB4041IPAPR operates at 1.1V and 3.3V.

Q: Does package size affect substitution compatibility?

A: Yes. TUSB2046BVFR maintains the same 32-LQFP (7x7) package as the original TUSB2046BIVFR, enabling direct PCB integration. TUSB4041IPAPR requires a 64-HTQFP (10x10) package, necessitating PCB layout redesign and footprint modification. Package selection depends on available board space and design constraints.

Q: Are both substitutes RoHS and REACH compliant?

A: Yes. Both TUSB2046BVFR and TUSB4041IPAPR are ROHS3 compliant and REACH unaffected, matching the compliance status of the original TUSB2046BIVFR. Both maintain MSL 3 moisture sensitivity ratings.

Q: Which substitute should be selected for new designs?

A: TUSB2046BVFR is the recommended choice for new designs requiring direct compatibility with existing TUSB2046BIVFR layouts. TUSB4041IPAPR is suitable only when extended temperature range (-40°C ~ 85°C) is required and PCB redesign is feasible. Verify supply voltage compatibility with your application power delivery system before final selection.
