PI3L110LE Equivalent & Substitute Parts

Part Overview

The PI3L110LE is a telecommunications switch IC manufactured by Diodes Incorporated, designed for 4-channel Ethernet switching applications in 10/100 Base-T networks. This interface component operates as a 2:1 multiplexer/demultiplexer with a 350MHz bandwidth and is housed in a 16-TSSOP package.

The PI3L110LE has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3L110LE is determined by the following critical parameters:

• Number of Channels: 4 (required)
• Multiplexer/Demultiplexer Circuit: 2:1 (required)
• On-State Resistance (Max): 8Ohm (required)
• Voltage - Supply, Single (V+): 3V ~ 3.6V (required)
• Features: 10/100 Base-T (required)
• Operating Temperature: -40°C ~ 85°C (TA) (required)
• Mounting Type: Surface Mount (required)
• RoHS Status: ROHS3 Compliant (required)

Substitute parts are grouped into two categories:

Direct Equivalent (Same Base Product): PI3L110LEX maintains identical electrical specifications and the same base product number (PI3L110) as the main part, differing only in packaging format (Cut Tape vs. standard packaging).

Cross-Manufacturer Alternatives (Texas Instruments TS3L110 Series): TS3L110DBQR, TS3L110DGVR, TS3L110PW, and TS3L110PWR meet all critical electrical and functional parameters. These parts feature enhanced -3dB bandwidth (500MHz vs. 350MHz) and SPDT switch circuit configuration, providing superior performance margins while maintaining full compatibility with the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

PI3L110LEX is the direct equivalent substitute for PI3L110LE. Both parts share identical electrical specifications and base product designation. PI3L110LEX carries Last Time Buy status, indicating limited future availability. Selection of this part is appropriate for applications requiring exact specification matching and minimal design validation.

TS3L110PWR is the primary recommended cross-manufacturer substitute. This Texas Instruments part maintains all critical electrical parameters while offering enhanced -3dB bandwidth (500MHz) and active product status, ensuring long-term supply chain availability. The 16-TSSOP package matches the original PI3L110LE footprint exactly, enabling direct board-level substitution without layout modifications.

TS3L110DGVR provides an alternative cross-manufacturer option with identical electrical performance to TS3L110PWR. The 16-TFSOP package maintains the same 0.173" width as the original part, supporting direct PCB substitution. This part carries active product status and unlimited moisture sensitivity rating.

TS3L110DBQR and TS3L110PW are functionally equivalent alternatives. TS3L110DBQR uses a 16-SSOP package (0.154" width), requiring PCB layout verification before implementation. TS3L110PW carries Last Time Buy status, limiting its suitability for new designs.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can PI3L110LEX be used as a direct replacement for PI3L110LE?

A: Yes. PI3L110LEX is a direct equivalent, sharing identical electrical specifications, base product number, and package dimensions. The only difference is packaging format (Cut Tape vs. standard). No design changes are required.

Q: What are the advantages of using TS3L110PWR instead of PI3L110LE?

A: TS3L110PWR provides enhanced -3dB bandwidth (500MHz vs. 350MHz), offering superior performance margin. The part carries active product status, ensuring long-term availability. The 16-TSSOP package is footprint-compatible with PI3L110LE, enabling direct substitution.

Q: Are there package compatibility differences between substitute parts?

A: Yes. TS3L110PWR, TS3L110PW, and PI3L110LEX use 16-TSSOP packages matching the original PI3L110LE footprint. TS3L110DGVR uses 16-TFSOP (same width, different profile). TS3L110DBQR uses 16-SSOP (0.154" width), requiring PCB layout verification before use.

Q: What is the moisture sensitivity difference between PI3L110LE and TS3L110DBQR?

A: PI3L110LE and most TS3L110 variants carry MSL 1 (Unlimited). TS3L110DBQR carries MSL 2 (1 Year), requiring controlled storage and handling procedures. This difference does not affect electrical compatibility.

Q: Which substitute part offers the best long-term supply availability?

A: TS3L110PWR carries active product status with 25,100 units in stock, providing the strongest supply chain position. This part is recommended for new designs and applications requiring extended component availability.

Q: Can TS3L110DBQR be used if PCB layout cannot be modified?

A: TS3L110DBQR uses a 16-SSOP package with 0.154" width, differing from the original 0.173" width. PCB layout verification is required. If layout modification is not possible, select TS3L110PWR, TS3L110DGVR, or PI3L110LEX instead.
