2N7002E N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The 2N7002E is an N-Channel MOSFET manufactured by Panasonic Electronic Components, rated for 60V drain-to-source voltage with 300mA continuous drain current in a surface mount SOT-23-3 package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The 2N7002E serves in general-purpose switching and amplification applications requiring low-voltage, low-current N-Channel MOSFET functionality. Substitution is required due to product discontinuation and the need for active, readily available alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 2N7002E is determined by the following critical parameters:

Mandatory Compatibility Criteria:

FET Type: N-Channel (all substitutes must be N-Channel)
Drain to Source Voltage (Vdss): 60V minimum (all substitutes rated at 60V)
Package Type: SOT-23-3 / TO-236 / TO-236AB (all substitutes use compatible surface mount packages)
Mounting Type: Surface Mount (all substitutes are surface mount)

Functional Compatibility Criteria:

Continuous Drain Current (Id): Minimum 300mA at 25°C (substitutes must support or exceed this rating)
Gate Threshold Voltage (Vgs(th)): Operating range compatibility (all substitutes within ±20V Vgs maximum)
Power Dissipation: Minimum 350mW (substitutes must support thermal requirements)

Substitutes are classified into two categories:

Direct Substitutes (electrically and mechanically equivalent):

2N7002BK,215 (Nexperia): Identical Vdss, higher Id (350mA), improved Rds On, active product status
2N7002K (Good-Ark Semiconductor): Identical Vdss and Id (300mA), active product status

Similar Substitutes (compatible but with parameter variations):

NX7002BKR (Nexperia): Vdss 60V, Id 270mA, lower power dissipation
BSN20BKR (Nexperia): Vdss 60V, Id 265mA, lower power dissipation
BSS138NH6433XTMA1 (Infineon): Vdss 60V, Id 230mA, lower power dissipation

All substitute parts maintain the same package footprint (SOT-23-3 / TO-236), enabling direct PCB replacement without layout modification.

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 2N7002BK,215 (Nexperia) is the primary direct substitute. It maintains 60V Vdss rating, exceeds the 300mA Id requirement at 350mA, and features improved on-resistance (1.6Ohm vs. 3Ohm). The part is active with AEC-Q101 automotive qualification and ROHS3 compliance. Nexperia's TrenchMOS™ series technology provides enhanced performance characteristics. Inventory availability is substantial (1,000,100 units).

The 2N7002K (Good-Ark Semiconductor) provides an alternative direct substitute with identical 60V/300mA ratings. This part is active with ROHS3 compliance and extended operating temperature range (−55°C to 175°C). Inventory availability is high (492,200 units).

For Current-Limited Applications:

The NX7002BKR, BSN20BKR, and BSS138NH6433XTMA1 are suitable substitutes where continuous drain current requirements are 270mA or lower. These parts maintain 60V Vdss compatibility and offer reduced power dissipation profiles. All three are active products with ROHS3 compliance and extended temperature ranges (−55°C to 150°C).

Selection Criteria:

Use 2N7002BK,215 or 2N7002K for applications requiring full 300mA+ current capability
Use NX7002BKR, BSN20BKR, or BSS138NH6433XTMA1 for applications with lower current demands or thermal constraints
All substitutes are surface mount compatible with identical SOT-23-3 / TO-236 footprints
All active substitutes provide superior product lifecycle support compared to the obsolete 2N7002E

Frequently Asked Questions (FAQ)

Q: Can the 2N7002E be directly replaced with any of these substitutes on the PCB?

A: Yes. All substitute parts use the same SOT-23-3 / TO-236 surface mount package with identical pin configuration. Direct PCB replacement is possible without layout modification. Pin-to-pin compatibility is maintained across all listed substitutes.

Q: What is the key difference between direct substitutes and similar substitutes?

A: Direct substitutes (2N7002BK,215 and 2N7002K) maintain the 300mA continuous drain current rating of the original 2N7002E. Similar substitutes (NX7002BKR, BSN20BKR, BSS138NH6433XTMA1) have lower Id ratings (230–270mA) and are suitable only for applications with reduced current requirements. Verify your circuit's maximum drain current before selecting a similar substitute.

Q: Are all substitutes RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original 2N7002E does not specify RoHS status. If RoHS compliance is a design requirement, all listed substitutes meet this criterion.

Q: Which substitute offers the best on-resistance performance?

A: The 2N7002K (Good-Ark Semiconductor) provides the lowest on-resistance at 0.3–0.6Ohm (measured at 4.5V and 5V drive voltages), compared to the original 2N7002E at 3Ohm. The 2N7002BK,215 offers 1.6Ohm at 10V drive voltage. Lower on-resistance reduces power dissipation and heat generation in switching applications.

Q: What is the operating temperature range difference?

A: The original 2N7002E is rated to 150°C junction temperature. The 2N7002K extends this to −55°C to 175°C. The NX7002BKR, BSN20BKR, and BSS138NH6433XTMA1 are rated −55°C to 150°C. Select based on your application's thermal environment and temperature extremes.

Q: Can I use a lower-current substitute (230–270mA) in place of the 300mA 2N7002E?

A: Only if your circuit's maximum drain current does not exceed the substitute's rating. Verify the peak and continuous drain current requirements in your application. Operating a MOSFET above its rated Id causes thermal stress and device failure. When in doubt, use a direct substitute with equal or higher current rating.

Q: What certifications should I verify for automotive or industrial applications?

A: The 2N7002BK,215 carries AEC-Q101 automotive qualification. For automotive designs, this part is the recommended choice. All active substitutes are ROHS3 and REACH compliant. Verify specific application standards (automotive, industrial, medical) before final part selection.

Q: Is there a performance advantage to using Nexperia, Infineon, or Good-Ark substitutes?

A: All manufacturers provide active products with equivalent electrical performance within the specified parameter ranges. Nexperia parts (2N7002BK,215, NX7002BKR, BSN20BKR) feature established supply chains and automotive qualification. Good-Ark's 2N7002K offers extended temperature range. Infineon's BSS138NH6433XTMA1 uses SIPMOS™ technology. Selection should be based on availability, cost, and specific application requirements rather than manufacturer preference alone.
