USB1T20MTCX Equivalent & Substitute Parts

Part Overview

The USB1T20MTCX is a half-duplex USB 2.0 transceiver IC manufactured by onsemi, designed for interface applications requiring 12 Mbps data rate operation. This component operates at 3V to 3.6V supply voltage and is housed in a 14-TSSOP surface mount package. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

The substitute part TSM900N06CP ROG is listed in the original component data; however, a direct functional substitution cannot be established based on the provided parameters. The USB1T20MTCX is a USB 2.0 interface transceiver, while TSM900N06CP ROG is an N-Channel MOSFET designed for power switching applications. These components operate in fundamentally different functional categories:

The USB1T20MTCX serves as a dedicated transceiver for USB 2.0 protocol communication with specific electrical characteristics including 12 Mbps data rate, half-duplex operation, and 1/1 driver/receiver configuration.

The TSM900N06CP ROG is a discrete power semiconductor with drain-source voltage rating of 60V and continuous drain current of 11A, intended for switching and power management applications.

Substitution between these parts is not technically valid based on functional requirements, protocol support, or electrical operating parameters. Any application requiring USB 2.0 transceiver functionality cannot be satisfied by a MOSFET component.

Parameter Comparison

Engineering Selection Recommendations

The USB1T20MTCX is obsolete and no functionally equivalent substitute part is available from the provided data. Selection of an alternative USB 2.0 transceiver requires identification of components meeting the following criteria:

USB 2.0 protocol support with 12 Mbps data rate capability

Half-duplex transceiver configuration with 1/1 driver/receiver architecture

Operating voltage range of 3V to 3.6V

Surface mount packaging compatible with 14-TSSOP footprint or equivalent

Operating temperature range of -40°C to 85°C minimum

ROHS3 compliance and REACH unaffected status for regulatory alignment

Moisture sensitivity level appropriate for manufacturing and storage conditions

For applications currently using USB1T20MTCX, direct replacement requires sourcing an active USB 2.0 transceiver from current manufacturer portfolios. The TSM900N06CP ROG listed in the original data does not fulfill transceiver functionality and cannot serve as a substitute.

Frequently Asked Questions (FAQ)

Q: Can TSM900N06CP ROG replace USB1T20MTCX in my application?

A: No. TSM900N06CP ROG is an N-Channel MOSFET designed for power switching applications. USB1T20MTCX is a USB 2.0 interface transceiver. These components serve different functional purposes and are not interchangeable.

Q: Why is USB1T20MTCX listed as obsolete?

A: Product obsolescence indicates the component is no longer manufactured or supported by onsemi. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: What parameters must an alternative USB 2.0 transceiver match?

A: Critical parameters include protocol support (USB 2.0), data rate (12 Mbps), duplex configuration (half-duplex), driver/receiver count (1/1), supply voltage (3V to 3.6V), operating temperature range (-40°C to 85°C), and package type (surface mount, 14-pin or compatible).

Q: Are there compliance considerations when selecting a substitute?

A: Yes. Any replacement component must maintain ROHS3 compliance and REACH unaffected status to ensure regulatory alignment with the original design.

Q: What package alternatives are acceptable?

A: The original USB1T20MTCX uses 14-TSSOP packaging. Substitute components should use identical or footprint-compatible packaging to minimize PCB redesign requirements.
