PI3L100QE Equivalent & Substitute Parts

Part Overview

The PI3L100QE is a telecommunications-grade ethernet switch IC manufactured by Diodes Incorporated, designed for 4-channel signal switching applications in 10/100 Base-T networking environments. This interface component operates as a 2:1 multiplexer/demultiplexer with active product status and full ROHS3 compliance. Substitute parts are identified when equivalent electrical performance, package compatibility, and functional specifications align with the original design requirements, enabling component sourcing flexibility across manufacturing lifecycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3L100QE are qualified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Number of Channels: 4 (exact match required)
• Multiplexer/Demultiplexer Circuit: 2:1 (exact match required)
• Package / Case: 16-SSOP form factor (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Features: 10/100 Base-T support (exact match required)

Secondary Compatibility Parameters:

• On-State Resistance (Max): 15 Ohm or lower (equal or superior performance)
• -3dB Bandwidth: 213 MHz or higher (equal or superior performance)
• Voltage Supply compatibility within specified operating ranges
• Operating Temperature range coverage
• RoHS3 compliance and MSL ratings

The identified substitutes (TS3L100DBQR and TS5L100DBQR) maintain the core functional architecture and package specifications while offering alternative sourcing from Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

TS3L100DBQR (Texas Instruments) qualifies as a primary substitute for the PI3L100QE. This part maintains active product status, identical channel count and multiplexer configuration, matching on-state resistance specifications, and superior bandwidth performance (350 MHz vs. 213 MHz). The supply voltage range (3V ~ 3.6V) encompasses the PI3L100QE operating point of 3.3V. Both components carry ROHS3 compliance and equivalent REACH/ECCN classifications. The primary design consideration is the reduced operating temperature range (0°C ~ 70°C vs. -40°C ~ 85°C) and MSL rating change from 1 to 2, which may impact applications requiring extended temperature operation or unlimited moisture exposure.

TS5L100DBQR (Texas Instruments) functions as a secondary substitute with significant electrical parameter deviations. This part carries Last Time Buy status, indicating discontinued production. The supply voltage requirement (6V ~ 6.5V) is incompatible with the PI3L100QE 3.3V specification without circuit redesign. On-state resistance increases to 19 Ohm (vs. 15 Ohm maximum), and operating temperature range is similarly restricted to 0°C ~ 70°C. This substitute is suitable only for applications where supply voltage can be adjusted and the higher on-state resistance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can TS3L100DBQR be used as a direct drop-in replacement for PI3L100QE?

A: TS3L100DBQR maintains identical channel count, multiplexer configuration, package form factor, and on-state resistance specifications. Direct substitution is possible in applications operating within the 0°C ~ 70°C temperature range. Applications requiring -40°C operation or unlimited moisture exposure (MSL 1) require design review due to the TS3L100DBQR MSL 2 rating and narrower temperature specification.

Q: What are the key electrical differences between PI3L100QE and TS5L100DBQR?

A: TS5L100DBQR operates at 6V ~ 6.5V supply voltage, compared to PI3L100QE at 3.3V. This voltage incompatibility requires circuit modification. On-state resistance is 19 Ohm (vs. 15 Ohm), representing a 26.7% increase in maximum resistance. Both maintain 4-channel 2:1 multiplexer architecture and 10/100 Base-T functionality.

Q: Are all substitute parts available in the same packaging options?

A: PI3L100QE is supplied in Tube packaging. TS3L100DBQR is available in Tape & Reel (TR) format. TS5L100DBQR is supplied in Cut Tape (CT) format. All three components use identical 16-SSOP package geometry (0.154", 3.90mm Width) and surface mount mounting type, ensuring PCB-level compatibility.

Q: What compliance certifications apply to all listed parts?

A: All three components (PI3L100QE, TS3L100DBQR, TS5L100DBQR) are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: Why does TS5L100DBQR show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued this product and no further production is planned. Existing inventory may be available, but long-term sourcing is not guaranteed. TS3L100DBQR maintains active status and represents the recommended Texas Instruments alternative.
