Substitute Part Grouping Explanation

Substitution of the 2N7002LT3G is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Drain to Source Voltage (Vdss): 60V minimum
FET Type: N-Channel
Technology: MOSFET (Metal Oxide)
Mounting Type: Surface Mount
Package compatibility: SOT-23-3 (TO-236) or equivalent footprint
Gate-Source Voltage (Vgs): ±20V maximum rating
Threshold Voltage Vgs(th): 2.0V to 2.5V @ 250µA

Allowable Parameter Variations:

Continuous Drain Current (Id): Equal to or greater than 115mA

Engineering Selection Recommendations

Direct Equivalents (Recommended for Pin-Compatible Replacement):

The 2N7002L (onsemi), 2N7002-TP (Micro Commercial Co), and 2N7002-7-F (Diodes Incorporated) provide direct electrical equivalence to the 2N7002LT3G with identical Vdss, Id, and Vgs(th) specifications. All three maintain SOT-23-3 package compatibility and Active product status. The 2N7002L and 2N7002-TP offer reduced power dissipation (200mW) compared to the primary part, while the 2N7002-7-F provides enhanced power handling (370mW) within the same footprint. All three are RoHS3 compliant with MSL 1 rating.

Alternative Manufacturer Equivalents:

The 2N7002 from UMW provides identical electrical performance with improved Rds On specification (5.0 Ohm versus 7.5 Ohm) and maintains Active status. This part is suitable for applications where lower on-resistance is beneficial. The 2N7002-G (onsemi) is electrically equivalent but carries Last Time Buy status, indicating limited future availability.

Enhanced Performance Variants:

The 2N7002K (Good-Ark Semiconductor), 2N7002A-7 (Diodes Incorporated), 2N7002E-7-F (Diodes Incorporated), and 2N7002E-T1-E3 (Vishay Siliconix) offer higher continuous drain current ratings (180mA to 300mA) and improved Rds On characteristics. These parts are suitable for applications requiring higher current handling or lower on-resistance losses while maintaining 60V Vdss rating and SOT-23-3 package compatibility. All maintain Active product status and full compliance certifications.

Package Variant:

The 2N7002T (onsemi) provides equivalent electrical performance in SC-89-3 package format. This variant is suitable only for designs that accommodate the smaller SC-89 footprint and should not be used as a direct replacement in existing SOT-23-3 layouts.

Frequently Asked Questions (FAQ)

Q: Can the 2N7002LT3G be replaced with the 2N7002K?

A: Yes. The 2N7002K meets all critical substitution parameters: 60V Vdss, N-Channel MOSFET, SOT-23 package, and RoHS3 compliance. The 2N7002K provides higher continuous drain current (300mA versus 115mA) and improved Rds On (0.3 Ohm versus 7.5 Ohm), making it suitable for applications requiring enhanced current handling. Electrical compatibility is confirmed across all gate-source voltage and threshold specifications.

Q: What is the difference between 2N7002LT3G and 2N7002L?

A: Both parts are manufactured by onsemi and share identical electrical specifications: 60V Vdss, 115mA continuous drain current, 7.5 Ohm Rds On, and 2.5V Vgs(th). The primary difference is power dissipation rating: 2N7002LT3G is rated at 225mW while 2N7002L is rated at 200mW. Both use SOT-23-3 packaging and maintain Active product status. The 2N7002L is suitable for applications with lower thermal requirements.

Q: Is the 2N7002T a direct replacement for the 2N7002LT3G?

A: The 2N7002T is electrically equivalent but uses SC-89-3 package instead of SOT-23-3. Direct replacement is not possible without PCB layout modification. The SC-89-3 package has a different footprint and pin configuration. Use the 2N7002T only in designs specifically designed for SC-89 package format.

Q: Can I use 2N7002-TP as a substitute?

A: Yes. The 2N7002-TP (Micro Commercial Co) is a direct substitute with identical electrical specifications: 60V Vdss, 115mA Id, 7.5 Ohm Rds On, and 2.5V Vgs(th). It uses SOT-23 packaging compatible with SOT-23-3 footprints and maintains Active product status with full RoHS3 compliance. Power dissipation is 200mW, which is lower than the primary part.

Q: What are the compliance and regulatory considerations for substitution?

A: All listed substitute parts maintain RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, matching the 2N7002LT3G. All parts carry EAR99 ECCN classification and identical HTSUS code (8541.21.0095). Substitution does not introduce regulatory or compliance issues.

Q: Which substitute offers the best performance improvement?

A: The 2N7002E-7-F and 2N7002E-T1-E3 provide the most significant performance enhancement with 3.0 Ohm Rds On (versus 7.5 Ohm) and higher continuous drain current (250mA and 240mA respectively). These parts reduce conduction losses and thermal dissipation in switching applications. Both maintain 60V Vdss, SOT-23-3 package compatibility, and Active product status.

Q: Are there inventory considerations for substitution?

A: Inventory levels vary significantly across manufacturers. The 2N7002T (onsemi) has the highest inventory at 726,730 pieces, while the 2N7002-G (onsemi) has limited availability at 2,300 pieces and carries Last Time Buy status. For long-term supply assurance, prioritize parts with Active status and higher inventory levels such as 2N7002-7-F (Diodes Incorporated) at 850,200 pieces or 2N7002K (Good-Ark Semiconductor) at 492,200 pieces.
