Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended for Pin-Compatible Replacement):

The following parts maintain identical electrical specifications and are suitable for direct substitution in applications requiring the original 2N7002-E3 performance envelope:

2N7002-TP (Micro Commercial Co): Matches all critical parameters including 115mA drain current, 7.5Ohm Rds On, and 200mW power dissipation. Active product status with established supply chain. RoHS3 compliant.
2N7002-7-F (Diodes Incorporated): Electrical equivalent with identical drain current and threshold voltage. Enhanced power dissipation rating (370mW) provides design margin. Active product status. RoHS3 compliant.
2N7002-G (onsemi): Matches original specifications exactly. Last Time Buy status indicates limited future availability; suitable for current production but not recommended for long-term design commitments.

Enhanced Performance Substitutes (For Improved Performance Margin):

These parts exceed the original specifications while maintaining full electrical compatibility:

2N7002K-T1-E3 (Vishay Siliconix): Manufacturer-recommended upgrade offering 300mA drain current (2.6× improvement), 2Ohm Rds On (73% reduction), and 350mW power dissipation. TrenchFET® technology. Active product status. Recommended for new designs requiring improved thermal performance or higher current capability.
2N7002E-7-F (Diodes Incorporated): Provides 250mA drain current (2.2× improvement) and 3Ohm Rds On (60% reduction) with 370mW power dissipation. Active product status. Suitable for applications requiring enhanced current handling.
2N7002ET1G (onsemi): Delivers 260mA drain current (2.3× improvement), 2.5Ohm Rds On (67% reduction), and reduced input capacitance (26.7pF). Active product status. Recommended for high-frequency switching applications.

The 2N7002 base product family from UMW provides highest inventory availability (1,000,100 pieces) with active product status, though specifications vary slightly from the original 2N7002-E3.

Frequently Asked Questions (FAQ)

Q1: Can I use 2N7002K-T1-E3 as a direct replacement for 2N7002-E3?

A: Yes. The 2N7002K-T1-E3 is electrically compatible and maintains all critical parameters: 60V Vdss, 2.5V Vgs(th), and SOT-23-3 package. The higher drain current (300mA vs. 115mA) and lower Rds On (2Ohm vs. 7.5Ohm) represent performance improvements that do not compromise compatibility. No circuit modifications are required.

Q2: What is the difference between 2N7002-TP and 2N7002-7-F?

A: Both parts are electrical equivalents with 115mA drain current and 7.5Ohm Rds On. The primary difference is manufacturer: 2N7002-TP is from Micro Commercial Co, while 2N7002-7-F is from Diodes Incorporated. The 2N7002-7-F offers higher power dissipation rating (370mW vs. 200mW), providing additional thermal margin. Both are suitable for direct substitution.

Q3: Why does 2N7002-TP-HF have such different specifications?

A: The 2N7002-TP-HF is a high-frequency variant optimized for applications requiring higher current handling and lower on-resistance. With 340mA drain current and 2.5Ohm Rds On, it is not a direct replacement but rather an enhanced alternative for designs that can benefit from improved performance. Use only if your application requires these enhanced specifications.

Q4: Is the 2N7002 from UMW a suitable substitute?

A: The UMW 2N7002 maintains the same base product number and critical electrical parameters (60V Vdss, 115mA Id, 2.5V Vgs(th)). However, it specifies 5Ohm Rds On (vs. 7.5Ohm) and 225mW power dissipation (vs. 200mW), representing minor improvements. The primary advantage is exceptional inventory availability. It is suitable for substitution with the understanding that specifications vary slightly.

Q5: Can I substitute 2N7002-G for 2N7002-E3?

A: Yes, the 2N7002-G from onsemi is an exact electrical equivalent. However, its Last Time Buy product status indicates limited future availability. It is suitable for current production but not recommended for designs requiring long-term component sourcing.

Q6: What is the significance of the operating temperature range difference in 2N7002 TR PBFREE?

A: The 2N7002 TR PBFREE from Central Semiconductor Corp extends the lower operating temperature limit to -65°C (vs. -55°C for the original). This represents an expanded operating range that maintains full compatibility. The part is suitable for applications requiring operation at lower temperatures.

Q7: How do I choose between multiple substitute options?

A: Selection depends on three factors: (1) Inventory availability and lead time requirements; (2) Performance margin needs—use enhanced variants (2N7002K-T1-E3, 2N7002E-7-F, 2N7002ET1G) if your application benefits from lower Rds On or higher current capability; (3) Long-term sourcing strategy—prioritize Active product status over Last Time Buy or Obsolete classifications. For standard applications, 2N7002-TP or 2N7002-7-F provide optimal balance of compatibility and availability.

Q8: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory compliance for current manufacturing standards.
