Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS3L110PW is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 16-TSSOP form factor (mandatory for PCB compatibility)
• Number of Channels: 4 channels (functional requirement)
• Multiplexer/Demultiplexer Circuit: 2:1 configuration
• Voltage Supply Range: 3V ~ 3.6V (power supply compatibility)
• Operating Temperature: -40°C ~ 85°C (environmental specification)
• Mounting Type: Surface Mount

Secondary Compatibility Parameters:

• On-State Resistance (Max): 8Ohm or lower (signal integrity)
• -3dB Bandwidth: 500MHz or higher (frequency performance)
• RoHS3 Compliance and MSL Level 1 (regulatory and manufacturing requirements)

Parts meeting all primary criteria and maintaining or exceeding secondary parameters are classified as direct substitutes. Application-specific features (10/100 Base-T for networking, USB 2.0 for USB applications) determine functional suitability within the broader interface category.

Parameter Comparison

Engineering Selection Recommendations

TS3L110PWR (Texas Instruments) is the primary recommended substitute. This part maintains identical electrical specifications to the TS3L110PW while offering Active product status, ensuring long-term availability and manufacturing support. Both parts share the same base product number (TS3L110) and are supplied in compatible 16-TSSOP packaging. The TS3L110PWR is available in Cut Tape and Digi-Reel packaging formats with significantly higher inventory levels (25,100 units), supporting production continuity.

FSUSB22MTCX (Fairchild Semiconductor) meets all primary substitution criteria with enhanced performance characteristics: 6.5Ohm on-state resistance (lower than the 8Ohm specification) and 750MHz bandwidth (exceeding the 500MHz requirement). However, this part is optimized for USB 2.0 applications rather than Ethernet networking. Selection of this substitute requires confirmation that the application can operate within USB 2.0 functional parameters while maintaining the 2:1 multiplexer configuration and 4-channel architecture.

PI3L110LEX (Diodes Incorporated) provides electrical compatibility across all primary parameters with identical 8Ohm on-state resistance and matching voltage supply range. This part is positioned for telecommunications applications and features 10/100 Base-T capability aligned with the main part's networking focus. However, the -3dB bandwidth specification of 350MHz is below the TS3L110PW's 500MHz rating, which may impact performance in high-frequency signal routing scenarios. Product status is Last Time Buy, similar to the main part.

Frequently Asked Questions (FAQ)

Q: Can TS3L110PWR be used as a direct replacement for TS3L110PW?

A: Yes. Both parts share identical electrical specifications, the same 16-TSSOP package footprint, and equivalent functional performance. The primary difference is packaging format (Tube for TS3L110PW versus Cut Tape/Digi-Reel for TS3L110PWR) and product status (Last Time Buy versus Active). PCB layout and design require no modification.

Q: What is the key difference between FSUSB22MTCX and the TS3L110PW?

A: FSUSB22MTCX is designed for USB 2.0 switching applications, while TS3L110PW targets Ethernet 10/100 Base-T networking. Although both share the 4-channel, 2:1 multiplexer architecture and 16-TSSOP package, the FSUSB22MTCX features superior on-state resistance (6.5Ohm) and bandwidth (750MHz). Application compatibility must be verified before substitution.

Q: Why does PI3L110LEX have lower bandwidth than TS3L110PW?

A: PI3L110LEX is optimized for telecommunications switching with a 350MHz bandwidth specification, compared to TS3L110PW's 500MHz. This difference reflects design optimization for different frequency ranges within the interface IC category. Selection depends on whether the application requires the full 500MHz bandwidth or can operate within the 350MHz specification.

Q: Are all substitute parts RoHS3 compliant?

A: TS3L110PWR and PI3L110LEX are confirmed ROHS3 Compliant. FSUSB22MTCX RoHS status is not specified in the provided data. Compliance verification with the component supplier is required before procurement if RoHS3 certification is a design requirement.

Q: What packaging options are available for each substitute?

A: TS3L110PW is supplied in Tube packaging. TS3L110PWR is available in Cut Tape and Digi-Reel formats. FSUSB22MTCX is supplied in Bulk packaging. PI3L110LEX is available in Cut Tape packaging. Packaging selection impacts inventory management and automated assembly processes.

Q: Can I use PI3L110LEX if my design operates at 500MHz?

A: PI3L110LEX's -3dB bandwidth specification is 350MHz, which is below the 500MHz requirement. Use of this part in applications requiring 500MHz performance is not supported by the provided specifications and requires direct verification with Diodes Incorporated.
