Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3L110QE is determined by the following critical parameters:

• Channel Configuration: 4-channel architecture
• Circuit Type: 2:1 multiplexer/demultiplexer topology
• On-State Resistance: Maximum 8Ω
• Supply Voltage: 3V ~ 3.6V single supply
• Bandwidth Performance: Minimum 350MHz (-3dB)
• Package Compatibility: 16-SSOP surface mount form factor with 0.154" (3.90mm) width
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Compliance: ROHS3 Compliant

The TS3L110DBQR from Texas Instruments meets all substitution criteria. It maintains identical channel count, supply voltage specifications, package dimensions, and operating temperature range. The substitute part exceeds the bandwidth requirement at 500MHz and maintains equivalent on-state resistance performance.

Parameter Comparison

Engineering Selection Recommendations

The TS3L110DBQR is a direct functional equivalent to the PI3L110QE. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The primary distinction is product status: the PI3L110QE is obsolete, while the TS3L110DBQR maintains active production status. This ensures long-term availability and supply chain stability for new designs or ongoing production requirements.

The TS3L110DBQR provides enhanced bandwidth performance at 500MHz compared to the PI3L110QE specification of 350MHz, delivering improved signal integrity margins for 10/100 Base-T Ethernet switching applications without requiring design modifications.

Frequently Asked Questions (FAQ)

Q: Can the TS3L110DBQR replace the PI3L110QE in existing designs?

A: Yes. The TS3L110DBQR is electrically and mechanically compatible. Both components share identical supply voltage ranges (3V ~ 3.6V), on-state resistance specifications (8Ω maximum), channel configuration (4-channel 2:1 multiplexer/demultiplexer), operating temperature range (-40°C ~ 85°C), and 16-SSOP package dimensions. No circuit modifications are required.

Q: What is the significance of the bandwidth difference between these parts?

A: The TS3L110DBQR operates at 500MHz (-3dB bandwidth) compared to the PI3L110QE at 350MHz. This represents enhanced performance headroom for high-speed signal transmission in 10/100 Base-T applications. The substitute part exceeds the original specification, ensuring compatibility with existing system requirements.

Q: Are there compliance or certification differences?

A: Both components are ROHS3 compliant and REACH unaffected. Compliance certifications are equivalent, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: Why is the PI3L110QE classified as obsolete?

A: Obsolete status indicates the component is no longer in active production by the manufacturer. The TS3L110DBQR, maintained in active production status by Texas Instruments, provides continuity for applications requiring 4-channel Ethernet switch functionality.

Q: Are there packaging or mounting differences?

A: Both components use identical 16-SSOP surface mount packages with 0.154" (3.90mm) width specifications. PCB layout and assembly processes require no modification for substitution.
