PI5PD2061TAEX Equivalent & Substitute Parts

Part Overview

The PI5PD2061TAEX is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 N-Channel output configuration. This component operates as a high-side switch with 1.5A maximum output current and integrated fault protection including current limiting, over-temperature, reverse current, and UVLO monitoring. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the PI5PD2061TAEX are identified based on strict electrical and mechanical parameter alignment within the USB power switch category. The substitution criteria are:

• Switch Type & Output Configuration: USB Switch with 1:1 N-Channel high-side output
• Current Rating: 1.5A maximum output current
• Load Voltage Range: Minimum 2.7V lower bound; upper bound tolerance up to 6V acceptable
• On-Resistance: 70mOhm typical specification
• Fault Protection: Current limiting, over-temperature, reverse current, and UVLO protection required
• Package Compatibility: SOT-23-5 or equivalent thin-profile variants (TSOT-23-5)
• Compliance: ROHS3 compliance mandatory

Two substitute parts meet these criteria with documented functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

RT9742MNGJ5 (Richtek USA Inc.) is the primary substitute for the PI5PD2061TAEX. This part maintains identical electrical specifications including 1.5A output current, 70mOhm on-resistance, and comprehensive fault protection (current limiting, over-temperature, reverse current, UVLO). The load voltage range extends to 6V, providing broader operational margin. The part is in active production status with ROHS3 compliance. Operating temperature range is limited to -40°C ~ 85°C (ambient), compared to the original -40°C ~ 125°C (junction). Moisture sensitivity level is MSL 3 (168 hours) versus MSL 1 (unlimited) for the original part. Package compatibility is confirmed with SOT-23-5 thin-profile variant (TSOT-23-5).

TPS3836L30QDBVRQ1 (Texas Instruments) is listed as a documented substitute but functions as a supervisor/reset IC rather than a direct power switch. This part operates with push-pull totem-pole output configuration and includes automotive-grade qualification (AEC-Q100). The voltage threshold is specified at 2.64V with 10ms minimum reset timeout. This part is suitable only for applications where supervisor functionality replaces the original switching function. Package compatibility is confirmed with SC-74A/SOT-753. Product status is active with ROHS3 compliance and MSL 1 (unlimited).

Frequently Asked Questions (FAQ)

Q: Can RT9742MNGJ5 directly replace PI5PD2061TAEX in all applications?

A: RT9742MNGJ5 provides electrical equivalence for USB switching applications with matching 1.5A current rating, 70mOhm on-resistance, and identical fault protection features. The operating temperature range differs (85°C ambient vs. 125°C junction), and moisture sensitivity is higher (MSL 3 vs. MSL 1). Verify application temperature requirements before substitution.

Q: What is the functional difference between RT9742MNGJ5 and TPS3836L30QDBVRQ1?

A: RT9742MNGJ5 is a power switch/driver with high-side N-Channel output for direct load switching. TPS3836L30QDBVRQ1 is a supervisor IC with push-pull output for reset/power-on reset functions. These serve different circuit roles and are not interchangeable in typical USB switch applications.

Q: Are package dimensions identical between PI5PD2061TAEX and RT9742MNGJ5?

A: Both parts use SOT-23-5 package family. PI5PD2061TAEX uses SC-74A/SOT-753 designation, while RT9742MNGJ5 uses TSOT-23-5 (thin variant). Verify PCB footprint compatibility; thin-profile variants may have different height specifications.

Q: Does TPS3836L30QDBVRQ1 meet the same current and switching requirements?

A: TPS3836L30QDBVRQ1 is a supervisor IC, not a power switch. It does not provide 1.5A switching capability or N-Channel output configuration. This part is suitable only for applications requiring reset/power-on reset supervision, not for USB power switching functions.

Q: What compliance certifications apply to substitute parts?

A: Both RT9742MNGJ5 and TPS3836L30QDBVRQ1 are ROHS3 compliant and REACH unaffected. TPS3836L30QDBVRQ1 includes automotive-grade qualification (AEC-Q100). All parts carry EAR99 ECCN classification and 8542.39.0001 HTSUS code.
