TS3USB3000MRSER USB Switch IC Equivalent & Substitute Parts

Part Overview

The TS3USB3000MRSER is an active USB switch integrated circuit manufactured by Texas Instruments, designed for high-speed USB 2.0 signal routing applications. This DPDT (Double Pole Double Throw) switch IC operates as a 1-channel multiplexer/demultiplexer with bi-directional capability, enabling dynamic USB port selection in multi-device configurations. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical performance, package compatibility, and supply voltage specifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS3USB3000MRSER are qualified based on the following critical parameters:

• Switch Configuration: DPDT topology with 1-channel operation for USB signal routing
• Electrical Performance: On-state resistance maximum 9 Ohm; -3dB bandwidth 6.1 GHz minimum
• Supply Voltage Compatibility: Single supply operation within 2.7V to 4.3V range
• Package Form Factor: 10-pin UQFN surface mount package (2.0x1.5mm)
• Signal Characteristics: Bi-directional USB 2.0 high-speed capability
• Compliance Requirements: RoHS3 compliance and EAR99 export classification

The FSUSB30L10X from Fairchild Semiconductor qualifies as a manufacturer-recommended substitute based on equivalent functional classification as a low-power 2-port high-speed USB switch IC with matching interface category designation and active product status.

Parameter Comparison

Engineering Selection Recommendations

Selection between the TS3USB3000MRSER and FSUSB30L10X is based on the following engineering criteria:

Primary Selection (TS3USB3000MRSER): Use when complete electrical parameter verification is required, including on-state resistance tolerance, bandwidth specification, and operating temperature range confirmation. Texas Instruments documentation provides comprehensive parametric data for design validation.

Substitute Selection (FSUSB30L10X): Use when supply chain constraints limit TS3USB3000MRSER availability. Both components share Active product status, identical export classification (EAR99), and matching HTSUS commodity codes (8542.39.0001), indicating functional equivalence within the USB switch IC category. Fairchild Semiconductor's low-power 2-port high-speed USB switch designation aligns with the original component's bi-directional USB 2.0 interface requirements.

Both parts maintain RoHS3 compliance pathway and are suitable for surface mount assembly processes. Verify package pinout compatibility and control signal timing specifications against application schematic requirements before final component selection.

Frequently Asked Questions (FAQ)

Q: What determines if FSUSB30L10X can replace TS3USB3000MRSER?

A: Both components are classified as Interface category USB switch ICs with Active product status. Substitution is valid when the application requires DPDT switching topology for USB 2.0 signal routing with bi-directional capability. Electrical parameters including on-state resistance, bandwidth, and supply voltage must be verified against application requirements.

Q: Are the packages physically compatible?

A: The TS3USB3000MRSER uses a 10-UQFN (2.0x1.5mm) surface mount package. Package compatibility for FSUSB30L10X must be confirmed through Fairchild Semiconductor datasheets, as package information was not provided in the substitute part specification.

Q: What is the supply voltage requirement for substitution?

A: The TS3USB3000MRSER operates on single supply voltage from 2.7V to 4.3V. When considering FSUSB30L10X as a substitute, verify that its supply voltage specification falls within or is compatible with this range through the manufacturer's technical documentation.

Q: Do both parts meet compliance requirements?

A: The TS3USB3000MRSER is RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control. The FSUSB30L10X shares the same EAR99 export classification and HTSUS code (8542.39.0001). RoHS3 compliance status for FSUSB30L10X must be confirmed through Fairchild Semiconductor documentation.

Q: What is the moisture sensitivity level consideration?

A: The TS3USB3000MRSER has MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling. Verify the FSUSB30L10X moisture sensitivity level through the manufacturer's packaging specifications before implementing in production environments.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability requires verification of pinout compatibility, control signal timing, and electrical performance specifications. Both components function as USB switch ICs, but design validation against application-specific requirements is necessary before substitution in production circuits.
