Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3L110QEX is determined by strict alignment with the following critical parameters:

• Channel Configuration: 4-channel quad switch architecture
• Multiplexer Type: 2:1 multiplexer/demultiplexer circuit topology
• On-State Resistance: Maximum 8 Ohm specification
• Supply Voltage: Single supply operation within 3V to 3.6V range
• Bandwidth Performance: Minimum -3dB bandwidth of 350 MHz for 10/100 Base-T compatibility
• Package Compatibility: 16-SSOP surface mount package with 0.154" width (3.90mm)
• Operating Temperature Range: -40°C to 85°C ambient temperature capability
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The TS3L110DBQR from Texas Instruments meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The TS3L110DBQR qualifies as a direct substitute for the PI3L110QEX based on electrical and mechanical parameter alignment. The substitute part maintains identical channel count, multiplexer topology, on-state resistance, supply voltage range, operating temperature range, and package configuration. The TS3L110DBQR provides enhanced -3dB bandwidth performance (500 MHz versus 350 MHz), which does not compromise compatibility and offers improved signal integrity margin for 10/100 Base-T applications.

The TS3L110DBQR holds Active product status with ongoing manufacturer support, providing supply continuity advantages over the PI3L110QEX Last Time Buy designation. Both parts maintain ROHS3 compliance and REACH unaffected regulatory status. Moisture sensitivity level differs (MSL 2 for TS3L110DBQR versus MSL 1 for PI3L110QEX), requiring standard handling procedures for the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the TS3L110DBQR directly replace the PI3L110QEX in existing designs?

A: Yes. The TS3L110DBQR meets all critical electrical and mechanical parameters: 4-channel configuration, 2:1 multiplexer topology, 8 Ohm on-state resistance, 3V to 3.6V supply voltage, and 16-SSOP package. Pin-to-pin compatibility and functional equivalence are established.

Q: What is the significance of the bandwidth difference (350 MHz vs. 500 MHz)?

A: The TS3L110DBQR exceeds the minimum bandwidth requirement for 10/100 Base-T operation. This performance margin improves signal fidelity and does not introduce compatibility issues. The substitute part is suitable for the specified application.

Q: Are there package handling differences between these parts?

A: The PI3L110QEX carries MSL 1 (Unlimited moisture sensitivity level), while the TS3L110DBQR carries MSL 2 (1 Year). Standard moisture control procedures apply to the substitute component during storage and assembly.

Q: Why is the PI3L110QEX in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The TS3L110DBQR, with Active status, provides long-term supply availability for equivalent functionality.

Q: Are regulatory certifications equivalent?

A: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing for telecommunications and networking applications.
