PI5PD2061UEEX Equivalent & Substitute Parts

Part Overview

The PI5PD2061UEEX is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 input-to-output ratio and N-Channel high-side output configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates across a 2.7V to 5.5V load voltage range with 1.5A maximum output current and integrated fault protection including current limiting, over-temperature monitoring, reverse current protection, and UVLO (Under-Voltage Lock-Out).

Substitute Part Grouping Explanation

Substitution analysis for the PI5PD2061UEEX is constrained by the following critical parameters: Switch Type (USB Switch vs. General Purpose), Number of Outputs (1 vs. 2), Input:Output Ratio (1:1 vs. 1:2), Maximum Output Current (1.5A vs. 1A), and Operating Temperature Range (-40°C ~ 125°C vs. -40°C ~ 105°C). The substitute parts identified fall into two functional categories:

Category 1: Battery Monitor ICs (BQ26200PW, BQ26200PWR, BQ26220PW, BQ26220PWR, BQ26221PW) — These Texas Instruments components share the 8-TSSOP package footprint and PMIC classification but serve a fundamentally different function (battery monitoring via HDQ interface) rather than power switching. These parts are not electrical substitutes for the PI5PD2061UEEX.

Category 2: Power Switch/Driver IC (TPS2066TDGNRQ1) — This Texas Instruments component is a Power Switch/Driver with N-Channel high-side output, high-side output configuration, and comparable fault protection (current limiting, over-temperature, UVLO). However, it features a 1:2 input-to-output ratio with 2 outputs and 1A maximum output current, differing from the PI5PD2061UEEX's 1:1 ratio with 1 output and 1.5A maximum current. The TPS2066TDGNRQ1 operates across the same 2.7V ~ 5.5V load voltage range and shares the same 70mOhm typical Rds On specification.

Parameter Comparison

Engineering Selection Recommendations

The TPS2066TDGNRQ1 represents the only functionally equivalent power switch alternative among the listed parts. This component maintains active product status with full manufacturer support, ROHS3 compliance, and AEC-Q100 automotive qualification. The TPS2066TDGNRQ1 shares critical electrical characteristics with the PI5PD2061UEEX including N-Channel high-side output configuration, identical load voltage range (2.7V ~ 5.5V), matching Rds On specification (70mOhm typical), and comparable fault protection architecture (current limiting, over-temperature, UVLO).

Design considerations for TPS2066TDGNRQ1 substitution include: reduced maximum output current (1A versus 1.5A), narrower operating temperature range (maximum 105°C ambient versus 125°C junction), and different output topology (1:2 ratio with dual outputs versus 1:1 ratio with single output). These differences require circuit-level evaluation to confirm compatibility with the original PI5PD2061UEEX application.

The BQ26200 and BQ26220/BQ26221 series components are battery monitoring ICs with HDQ interface functionality and are not suitable as electrical substitutes for the PI5PD2061UEEX power switch application.

Frequently Asked Questions (FAQ)

Q: Can the TPS2066TDGNRQ1 directly replace the PI5PD2061UEEX in existing designs?

A: The TPS2066TDGNRQ1 shares the same package footprint (8-TSSOP, 8-MSOP with exposed pad) and load voltage range, enabling PCB-level compatibility. However, the 1:2 output ratio and dual-output configuration differ from the PI5PD2061UEEX's 1:1 single-output design. Circuit topology must be evaluated to confirm functional equivalence for the specific application.

Q: What is the significance of the different output current ratings (1.5A vs. 1A)?

A: The PI5PD2061UEEX supports 1.5A maximum output current while the TPS2066TDGNRQ1 supports 1A per output. Applications requiring sustained currents above 1A per channel require thermal and current distribution analysis to confirm the TPS2066TDGNRQ1 meets load requirements.

Q: Why are the BQ26200 and BQ26220 series listed if they are not substitutes?

A: These components were identified in the manufacturer's substitute list but serve a different functional purpose (battery monitoring via HDQ interface). They share the PMIC category and 8-TSSOP package family but are not electrical equivalents for power switching applications.

Q: How do the operating temperature ranges affect substitution?

A: The PI5PD2061UEEX operates to 125°C junction temperature, while the TPS2066TDGNRQ1 operates to 105°C ambient temperature. Applications requiring operation above 105°C ambient or with high thermal margins require thermal modeling to confirm the TPS2066TDGNRQ1 meets reliability requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The PI5PD2061UEEX, TPS2066TDGNRQ1, BQ26200 series, and BQ26220/BQ26221 series are all ROHS3 compliant. All parts meet REACH unaffected status and carry EAR99 ECCN classification.

Q: What packaging options are available for the TPS2066TDGNRQ1?

A: The TPS2066TDGNRQ1 is available in Cut Tape (CT) & Digi-Reel packaging. The PI5PD2061UEEX was available in standard packaging. Verify packaging requirements for production volume and handling specifications.
