TUSB1105RGTR Equivalent & Substitute Parts

Part Overview

The TUSB1105RGTR is a half-duplex USB 2.0 transceiver manufactured by Texas Instruments, designed for interface applications requiring single driver/receiver functionality. This component operates across a supply voltage range of 1.65V to 3.6V and supports data rates up to 1.5Mbps with a receiver hysteresis of 450mV. The device is housed in a 16-VQFN (3x3) surface mount package with exposed pad and maintains active product status with full RoHS3 compliance. Substitute parts are identified when electrical specifications, functional parameters, and package compatibility remain equivalent across manufacturing variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TUSB1105RGTR is determined by equivalence across the following critical parameters:

• Protocol specification (USB 2.0)
• Transceiver configuration (1/1 drivers/receivers, half-duplex)
• Electrical performance (1.5Mbps data rate, 450mV receiver hysteresis)
• Supply voltage range (1.65V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package (16-VQFN 3x3 with exposed pad)
• Surface mount compatibility
• Compliance certifications (RoHS3, REACH Unaffected)

The TUSB1106RGTR qualifies as a parametric equivalent substitute based on identical electrical specifications and package configuration. Packaging format differences (Cut Tape vs. Tape & Reel) do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the TUSB1105RGTR and TUSB1106RGTR maintain active product status from Texas Instruments and carry identical compliance certifications including RoHS3 and REACH Unaffected designations. Selection between these parts is determined by packaging availability and supply chain requirements rather than functional performance. The TUSB1105RGTR is supplied in Cut Tape (CT) & Digi-Reel® format with 4146 units in stock, while the TUSB1106RGTR is supplied in Tape & Reel (TR) format with 3089 units in stock. Both parts are suitable for production assembly processes compatible with their respective packaging formats.

Frequently Asked Questions (FAQ)

Q: Can TUSB1106RGTR replace TUSB1105RGTR in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, data rates, supply voltage ranges, operating temperatures, and package configurations. The difference is packaging format only.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is suitable for lower-volume applications and manual handling, while Tape & Reel (TR) packaging is optimized for automated assembly processes. Both formats contain the same component in the same 16-VQFN package.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, MSL rating of 1 (Unlimited), and ECCN/HTSUS classifications.

Q: What are the critical parameters for substitution?

A: USB 2.0 protocol, 1/1 transceiver configuration, half-duplex operation, 1.5Mbps data rate, 450mV receiver hysteresis, 1.65V–3.6V supply voltage, -40°C to 85°C operating range, and 16-VQFN (3x3) package with exposed pad.

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

A: Yes. Both parts use identical pin configurations and package footprints, allowing direct substitution without PCB redesign.
