NDS336P P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The NDS336P is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 1.2A continuous drain current at 25°C. The device is packaged in SOT-23-3 (TO-236-3) surface mount configuration and dissipates a maximum of 500mW. The NDS336P is classified as obsolete product status, making identification of equivalent and substitute components necessary for ongoing design support, production continuity, and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NDS336P is determined by strict equivalence in the following parameters:

Critical Matching Parameters:

• FET Type: P-Channel (all substitutes must be P-Channel)
• Drain to Source Voltage (Vdss): 20V minimum rating
• Package Type: SOT-23-3 surface mount configuration
• Operating Temperature Range: -55°C to 150°C (TJ)
• Gate Voltage (Vgs Max): ±8V or greater

Allowable Variation Parameters:

• Continuous Drain Current (Id): Equal to or greater than 1.2A
• Rds On (Max): Equal to or less than 200mOhm (lower resistance is acceptable)
• Power Dissipation (Max): Equal to or greater than 500mW
• Gate Charge (Qg): No restriction on reduction
• Input Capacitance (Ciss): No restriction on reduction

All three substitute parts meet the critical matching parameters and fall within allowable variations for drain current, on-resistance, and power dissipation ratings.

Parameter Comparison

Engineering Selection Recommendations

FDN336P (onsemi): This part provides the closest electrical equivalence to the NDS336P with identical Vdss (20V), matching Rds On specification (200mOhm @ 4.5V), and equivalent power dissipation (500mW). The FDN336P is rated for 1.3A continuous drain current, exceeding the NDS336P requirement of 1.2A. Product status is Active with ROHS3 compliance. This part is recommended as the primary substitute for direct replacement applications requiring minimal design modification.

NTR4101PT1G (onsemi): This part exceeds NDS336P specifications with 1.8A continuous drain current and significantly improved Rds On performance (85mOhm @ 4.5V). Power dissipation is rated at 420mW, which is lower than the NDS336P but remains adequate for most applications. Product status is Active with ROHS3 compliance. This part is suitable for applications where improved efficiency and higher current capability are beneficial.

DMG2301LK-13 (Diodes Incorporated): This part provides the highest performance rating with 2.4A continuous drain current and 840mW power dissipation. Rds On is 160mOhm @ 4.5V, and Vgs maximum rating is ±12V, providing additional gate voltage margin. The device carries AEC-Q101 automotive qualification and ROHS3 compliance. This part is suitable for applications requiring automotive-grade reliability or higher current and power handling capacity.

All three substitutes maintain SOT-23-3 package compatibility, identical operating temperature range (-55°C to 150°C), and equivalent Vdss rating (20V). Selection should be based on specific application requirements for current capacity, power dissipation, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the FDN336P directly replace the NDS336P without circuit modification?

A: Yes. The FDN336P meets all critical electrical parameters of the NDS336P: identical 20V Vdss rating, matching 200mOhm Rds On specification, equivalent 500mW power dissipation, and identical SOT-23-3 package. The 1.3A rating exceeds the 1.2A requirement. No circuit modification is required.

Q: What is the primary difference between NTR4101PT1G and NDS336P?

A: The NTR4101PT1G provides superior performance with 1.8A continuous drain current (versus 1.2A) and significantly lower Rds On of 85mOhm (versus 200mOhm). Both devices share identical 20V Vdss rating, SOT-23-3 package, and operating temperature range. The NTR4101PT1G is suitable for applications where lower on-resistance and higher current capacity provide system benefits.

Q: Is the DMG2301LK-13 suitable for automotive applications?

A: Yes. The DMG2301LK-13 carries AEC-Q101 automotive qualification and ROHS3 compliance. It provides the highest performance specifications among the substitutes with 2.4A continuous drain current and 840mW power dissipation. This part is appropriate for automotive-grade designs requiring enhanced reliability.

Q: Are all substitute parts available in the same package as the NDS336P?

A: Yes. All three substitute parts (FDN336P, NTR4101PT1G, and DMG2301LK-13) are packaged in SOT-23-3 (TO-236-3, SC-59) surface mount configuration, identical to the NDS336P. No PCB layout modification is required for package compatibility.

Q: What is the significance of the NDS336P being classified as obsolete?

A: Obsolete product status indicates the NDS336P is no longer manufactured or supported by onsemi. The FDN336P, NTR4101PT1G, and DMG2301LK-13 are all classified as Active products with current manufacturing support, ensuring long-term availability and supply chain continuity.

Q: Can the NTR4101PT1G be used in applications originally designed for the NDS336P?

A: Yes. The NTR4101PT1G exceeds all minimum specifications of the NDS336P while maintaining identical package and voltage ratings. The improved Rds On (85mOhm versus 200mOhm) and higher current rating (1.8A versus 1.2A) make it suitable for direct substitution. Applications will benefit from reduced power dissipation and improved thermal performance.

Q: What compliance certifications apply to these substitute parts?

A: FDN336P and NTR4101PT1G carry ROHS3 compliance. DMG2301LK-13 carries both ROHS3 compliance and AEC-Q101 automotive qualification. All three parts are REACH Unaffected and classified under ECCN EAR99. The NDS336P compliance status is not specified in available documentation.
