Substitute Part Grouping Explanation

Substitution of the PI3L110LEX is determined by strict equivalence across the following critical parameters:

Channel Configuration: 4-channel architecture with 2:1 multiplexer/demultiplexer functionality
Electrical Performance: On-state resistance maximum of 8Ω and supply voltage range of 3V to 3.6V
Signal Integrity: -3dB bandwidth capability supporting 10/100 Base-T Ethernet applications
Package Compatibility: 16-TSSOP surface mount package with identical physical dimensions
Environmental & Compliance: Operating temperature range -40°C to 85°C, ROHS3 compliance, and MSL 1 rating

The TS3L110PWR from Texas Instruments meets all these substitution criteria and is classified as the manufacturer-recommended equivalent.

Engineering Selection Recommendations

The TS3L110PWR is the appropriate substitute for the PI3L110LEX based on the following factors:

Product Status Alignment: The PI3L110LEX is designated Last Time Buy, indicating end-of-life status. The TS3L110PWR maintains Active product status with 25,100 units in current inventory, ensuring long-term availability and supply chain continuity.

Compliance & Certification: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 ratings, ensuring regulatory and environmental requirements are preserved across substitution.

Electrical & Functional Equivalence: The TS3L110PWR matches all critical electrical parameters including supply voltage, on-state resistance, channel configuration, and operating temperature range. The enhanced -3dB bandwidth of 500MHz in the TS3L110PWR exceeds the PI3L110LEX specification of 350MHz, providing additional performance margin without compromising compatibility.

Package Compatibility: Identical 16-TSSOP packaging ensures direct board-level substitution without PCB redesign or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TS3L110PWR directly replace the PI3L110LEX in existing designs?

A: Yes. The TS3L110PWR is pin-compatible and functionally equivalent across all critical parameters. The 16-TSSOP package dimensions are identical, and electrical specifications match or exceed the PI3L110LEX requirements. No PCB modifications are required.

Q: What is the significance of the higher -3dB bandwidth in the TS3L110PWR?

A: The TS3L110PWR provides 500MHz bandwidth compared to the PI3L110LEX at 350MHz. This represents enhanced signal integrity performance and provides additional margin for 10/100 Base-T Ethernet applications. The higher bandwidth does not introduce compatibility issues and supports future performance requirements.

Q: Are there any supply voltage or thermal differences between these parts?

A: No. Both parts operate identically across the 3V to 3.6V supply range and share the same -40°C to 85°C operating temperature specification. Thermal and power management considerations remain unchanged.

Q: Why is the PI3L110LEX in Last Time Buy status?

A: Last Time Buy designation indicates the manufacturer is discontinuing production. The TS3L110PWR from Texas Instruments provides continuity for new designs and ongoing production requirements.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Handling and storage procedures are identical.

Q: Does the switch circuit designation affect substitution compatibility?

A: The PI3L110LEX lists switch circuit as not specified, while the TS3L110PWR specifies SPDT (Single Pole Double Throw). Both parts function as 4-channel 2:1 multiplexer/demultiplexer switches suitable for Ethernet switching applications. The SPDT designation in the TS3L110PWR describes the internal switch topology and does not affect functional compatibility.
