PI5A100WE Equivalent & Substitute Parts

Part Overview

The PI5A100WE is a 4-circuit SPDT IC switch manufactured by Diodes Incorporated, designed for general-purpose analog switching applications. It operates across a 2V to 6V single supply range with 10Ohm on-state resistance and features a 230MHz bandwidth. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5A100WE is determined by the following critical parameters:

Core Functional Requirements:

• Switch Circuit: SPDT
• Number of Circuits: 4
• Multiplexer/Demultiplexer Circuit: 2:1
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• On-State Resistance (Max): 10Ohm

Supply Voltage Compatibility: The PI5A100WE operates at 2V ~ 6V single supply. Substitutes must support overlapping or compatible voltage ranges within this specification.

Performance Characteristics: Substitutes are grouped based on bandwidth, switch time, and leakage current specifications. Parts with superior performance characteristics (lower leakage, faster switching, higher bandwidth) are direct substitutes when voltage and resistance requirements are met.

Compliance & Status: All substitute parts maintain ROHS3 compliance, MSL Level 1, and equivalent environmental certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

TS3A5018DR is the preferred substitute for the PI5A100WE. It maintains identical on-state resistance (10Ohm), operates within a compatible voltage range (1.65V ~ 3.6V overlaps the PI5A100WE's 2V ~ 6V range), and offers superior performance characteristics including faster switching times (8ns vs 15ns), higher bandwidth (300MHz vs 230MHz), and significantly lower leakage current (100nA vs 10µA). The part is currently Active in product status with 19,100 units in stock, ensuring long-term availability. Packaging is identical 16-SOIC format.

TS3A5018D is functionally equivalent to TS3A5018DR with identical electrical specifications but differs in packaging (Tube vs Cut Tape). This part carries Last Time Buy status, indicating limited future availability.

Secondary Substitutes (Conditional Use):

TS3L100DR and TS5L100D/TS5L100DR are networking-specific switch ICs with higher on-state resistance (15Ohm and 19Ohm respectively) and different voltage supply ranges. TS3L100DR operates at 3V ~ 3.6V, while TS5L100D and TS5L100DR require 6V ~ 6.5V supply. These parts are suitable only for applications where the higher resistance and narrower voltage ranges are acceptable. Both TS5L100D and TS5L100DR carry Last Time Buy status.

Compliance & Availability:

All substitute parts maintain ROHS3 compliance and MSL Level 1 ratings, ensuring equivalent environmental and handling requirements. TS3A5018DR is the only substitute with Active product status, making it the optimal choice for designs requiring long-term component availability and support.

Frequently Asked Questions (FAQ)

Q: Can TS3A5018DR directly replace PI5A100WE in existing designs?

A: Yes. Both parts feature identical 4-circuit SPDT 2:1 multiplexer configuration with 10Ohm on-state resistance in 16-SOIC packaging. The voltage range overlap (1.65V ~ 3.6V for TS3A5018DR falls within the PI5A100WE's 2V ~ 6V specification) ensures functional compatibility. TS3A5018DR offers superior performance with faster switching and lower leakage current.

Q: What is the voltage range compatibility between PI5A100WE and its substitutes?

A: The PI5A100WE operates at 2V ~ 6V. TS3A5018D and TS3A5018DR support 1.65V ~ 3.6V, which overlaps the lower portion of the PI5A100WE range. TS3L100DR requires 3V ~ 3.6V. TS5L100D and TS5L100DR require 6V ~ 6.5V, which overlaps only the upper portion. Verify your circuit's supply voltage before selecting a substitute.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use identical 16-SOIC (0.154", 3.90mm Width) packaging. Differences exist only in supplier packaging format: TS3A5018D is supplied in Tube, TS3A5018DR in Cut Tape (CT) & Digi-Reel, TS3L100DR in Tape & Reel (TR), TS5L100D in Tube, and TS5L100DR in Cut Tape (CT). These differences do not affect PCB footprint or electrical performance.

Q: Why do TS5L100D and TS5L100DR have higher on-state resistance?

A: TS5L100D and TS5L100DR are optimized for networking applications (10/100 Base-T) and operate at higher supply voltages (6V ~ 6.5V). The 19Ohm on-state resistance reflects their design for this specific application domain. Use these parts only if your circuit operates at 6V ~ 6.5V and can tolerate the increased resistance.

Q: What is the difference between TS3A5018D and TS3A5018DR?

A: Both parts are electrically identical with the same specifications. The difference is packaging format: TS3A5018D is supplied in Tube, while TS3A5018DR is supplied in Cut Tape (CT) & Digi-Reel. TS3A5018DR is currently Active, while TS3A5018D carries Last Time Buy status.

Q: Is the PI5A100WE still available?

A: The PI5A100WE is discontinued at DiGi Electronics. TS3A5018DR is the recommended active substitute with 19,100 units currently in stock.
