2N7002_S00Z N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The 2N7002_S00Z is an N-Channel MOSFET manufactured by onsemi, rated for 60V drain-to-source voltage with 115mA continuous drain current in a surface mount SOT-23-3 package. This device is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with modified performance characteristics suitable for specific application requirements.

Substitute Part Grouping Explanation

Substitution of the 2N7002_S00Z is determined by the following critical parameters: drain-to-source voltage rating (Vdss), continuous drain current capability (Id), on-state resistance (Rds On), gate threshold voltage (Vgs(th)), power dissipation rating, operating temperature range, and package form factor. Parts are grouped into three categories based on functional equivalence:

Category 1: Direct Electrical Equivalents — Parts maintaining identical Vdss (60V), Id (115mA), Rds On (7.5Ohm @ 500mA, 10V), and SOT-23-3 package configuration. These parts are pin-compatible and electrically interchangeable without circuit modification.

Category 2: Enhanced Performance Substitutes — Parts with identical Vdss (60V) and SOT-23-3 package but higher Id ratings (260mA to 320mA) and lower Rds On values. These parts provide improved current handling and reduced power dissipation while maintaining voltage compatibility and package compatibility.

Category 3: Alternative Package Substitutes — Parts with identical electrical specifications but different surface mount packages (SC-89-3). These require PCB layout modification but maintain electrical performance.

Category 4: Voltage-Reduced Substitutes — Parts with lower Vdss ratings (20V) that are not suitable for direct substitution but may be considered for applications with reduced voltage requirements.

Engineering Selection Recommendations

Direct Replacement (Pin-Compatible, Electrically Equivalent):

The 2N7002L (onsemi) and 2N7002LT1G (onsemi) are direct replacements for the 2N7002_S00Z. Both maintain 60V Vdss, 115mA Id, 7.5Ohm Rds On, and SOT-23-3 package configuration. The 2N7002L carries active product status with RoHS3 compliance. The 2N7002LT1G provides marginally higher power dissipation (225mW vs. 200mW) and is available in higher inventory quantities (360,300 units). Both parts are REACH unaffected and carry EAR99 ECCN classification.

The 2N7002-T1-E3 (Vishay Siliconix) provides electrical equivalence with identical specifications and active product status. This part is suitable for applications where Vishay component qualification is required.

Enhanced Performance Substitutes (Same Voltage, Higher Current Capability):

The 2N7002ET1G (onsemi) and 2N7002KT1G (onsemi) provide superior current handling (260mA and 320mA respectively) with significantly reduced Rds On values (2.5Ohm and 1.6Ohm). Both maintain 60V Vdss and SOT-23-3 package compatibility. These parts are suitable for applications requiring higher current capacity or lower power dissipation. Both carry active product status and RoHS3 compliance.

The 2N7002K (Good-Ark Semiconductor) offers 300mA current capability with extended operating temperature range (-55°C to 175°C). This part is suitable for high-temperature applications but requires SOT-23 package consideration.

Alternative Package Substitutes:

The 2N7002T (onsemi) maintains electrical equivalence but uses SC-89-3 package instead of SOT-23-3. This part is suitable only for applications where SC-89-3 footprint is available on the PCB.

Not Recommended for Direct Substitution:

The MMBF0201NLT1G (onsemi) has reduced Vdss rating (20V) and is not suitable for 60V applications. The UMW 2N7002 part has improved Rds On (5.0Ohm) but uses standard SOT-23 package without the -3 designation.

Frequently Asked Questions (FAQ)

Q: Can the 2N7002L directly replace the 2N7002_S00Z without circuit modification?

A: Yes. The 2N7002L maintains identical electrical specifications (60V Vdss, 115mA Id, 7.5Ohm Rds On) and SOT-23-3 package configuration. Pin assignment and electrical behavior are identical, requiring no circuit modification.

Q: What is the difference between 2N7002LT1G and 2N7002L?

A: Both parts maintain identical electrical specifications and SOT-23-3 package. The primary difference is power dissipation rating: 2N7002LT1G is rated for 225mW (Ta) compared to 200mW (Ta) for 2N7002L. The 2N7002LT1G provides additional thermal margin and is available in higher inventory quantities.

Q: Can I use 2N7002ET1G or 2N7002KT1G as substitutes?

A: Yes, with application-specific considerations. Both parts maintain 60V Vdss and SOT-23-3 package compatibility. However, they provide higher current ratings (260mA and 320mA) and lower Rds On values. These characteristics are beneficial for applications requiring higher current handling or lower power dissipation. No circuit modification is required, but thermal design may be optimized due to improved performance characteristics.

Q: Why is the 2N7002T not recommended as a direct replacement?

A: The 2N7002T uses SC-89-3 package instead of SOT-23-3. While electrical specifications are identical, the different package footprint requires PCB layout modification. This part is suitable only for designs already incorporating SC-89-3 footprints.

Q: Is the MMBF0201NLT1G suitable for my 60V application?

A: No. The MMBF0201NLT1G has maximum Vdss rating of 20V and cannot be used in 60V applications. Using this part in a 60V circuit will result in device failure.

Q: What compliance certifications apply to substitute parts?

A: All recommended substitute parts carry RoHS3 compliance and REACH unaffected status. All parts are classified as EAR99 for export control purposes. Moisture sensitivity level is MSL 1 (unlimited) for all parts, indicating no moisture sensitivity precautions are required.

Q: Can I mix different manufacturers' 2N7002 variants in the same design?

A: Yes. All 2N7002 variants with identical electrical specifications (60V Vdss, 115mA Id, 7.5Ohm Rds On, SOT-23-3 package) are electrically interchangeable. However, component sourcing and supply chain considerations may warrant standardization on a single manufacturer variant for production consistency.

Q: What is the inventory status for substitute parts?

A: The 2N7002LT1G (onsemi) has the highest inventory availability at 360,300 units. The 2N7002T (onsemi) has 726,730 units available. The 2N7002-T1-E3 (Vishay Siliconix) has lower availability at 13,273 units. Inventory levels should be verified with suppliers for current availability.
