PI5L200WEX Equivalent & Substitute Parts

Part Overview

The PI5L200WEX is a telecommunications switch IC manufactured by Diodes Incorporated, featuring 4 channels in a 16-SOIC package. This device functions as a quad SPDT switch designed for 10/100 Base-T and LAN applications. The part is currently in Active product status with 1754 units in stock.

Substitute parts become necessary when the main part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative electrical characteristics. The TS5L100D and TS5L100DR from Texas Instruments are listed as manufacturer-recommended alternatives, though both carry Last Time Buy status, indicating their own lifecycle considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI5L200WEX is determined by the following critical parameters:

Mechanical Compatibility: Both substitute parts (TS5L100D and TS5L100DR) share the identical 16-SOIC package footprint (0.154", 3.90mm Width), enabling direct PCB-level replacement without layout modifications.

Functional Equivalence: All three parts provide 4-channel SPDT switching with 2:1 multiplexer/demultiplexer configuration, maintaining functional parity for telecommunications and networking switch applications.

Electrical Tolerance: The substitute parts operate at 6V ~ 6.5V single supply voltage, which differs from the PI5L200WEX operating range of 3.3V and 5V. The TS5L100 series exhibits higher on-state resistance (19 Ohm maximum versus 12 Ohm) and superior bandwidth performance (350 MHz versus 137 MHz).

Compliance Alignment: All parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring regulatory consistency across substitution.

Packaging Variants: TS5L100D is supplied in Tube packaging, while TS5L100DR is supplied in Cut Tape (CT) packaging, offering flexibility in procurement format.

Parameter Comparison

Engineering Selection Recommendations

Active Status Preference: The PI5L200WEX maintains Active product status with 1754 units currently in stock, providing the longest lifecycle availability and supply continuity. This part should remain the primary selection for new designs and ongoing production.

Substitute Consideration Triggers: The TS5L100D and TS5L100DR should be evaluated only when PI5L200WEX availability becomes constrained or when design specifications explicitly require the enhanced bandwidth performance (350 MHz versus 137 MHz) or alternative supply voltage range (6V ~ 6.5V).

Last Time Buy Status Impact: Both Texas Instruments alternatives carry Last Time Buy designation, indicating these parts are approaching end-of-life. Substitution to these parts introduces future supply risk and should be accompanied by long-term inventory planning.

Compliance Consistency: All three parts maintain equivalent regulatory compliance (ROHS3, MSL Level 1, REACH Unaffected), eliminating compliance-based selection constraints.

Electrical Parameter Trade-offs: Substitution introduces measurable electrical differences: increased on-state resistance (19 Ohm versus 12 Ohm) and narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C). These differences must be evaluated against specific application requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can TS5L100D and TS5L100DR be used interchangeably with PI5L200WEX?

A: Both Texas Instruments parts share identical electrical specifications and package footprint, enabling direct substitution at the PCB level. However, the supply voltage range differs (6V ~ 6.5V versus 3.3V, 5V), requiring circuit-level verification before implementation.

Q: What are the key electrical differences between these parts?

A: The primary differences are on-state resistance (PI5L200WEX: 12 Ohm maximum; TS5L100 series: 19 Ohm maximum), bandwidth performance (PI5L200WEX: 137 MHz; TS5L100 series: 350 MHz), and operating temperature range (PI5L200WEX: -40°C ~ 85°C; TS5L100 series: 0°C ~ 70°C).

Q: Why do the substitute parts have Last Time Buy status?

A: Last Time Buy status indicates these products are in their final production phase and will be discontinued. This status reflects the manufacturer's lifecycle management and does not affect current electrical performance or compliance.

Q: Are the packaging formats interchangeable?

A: The 16-SOIC package footprint is identical across all three parts, enabling direct PCB replacement. However, procurement packaging differs: PI5L200WEX is supplied in Tape & Reel (TR), TS5L100D in Tube, and TS5L100DR in Cut Tape (CT). These packaging differences affect handling and assembly processes but not component functionality.

Q: Which part should be selected for new designs?

A: The PI5L200WEX should be the primary selection for new designs due to its Active product status, extended operating temperature range, and lower on-state resistance. Substitute parts should be considered only when specific design requirements or supply constraints necessitate their use.

Q: Do all parts meet the same regulatory requirements?

A: Yes. All three parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring equivalent regulatory alignment across substitution scenarios.
