Key electrical and mechanical differences between the two devices
| Parameter | 2N7002K | 2N7002K-7 | Why it matters |
|---|---|---|---|
| Drain-Source Voltage (VDS) | 60 V | 60 V | Defines the maximum voltage the MOSFET can block; must match or exceed the circuit's voltage stress for safe substitution. |
| Continuous Drain Current (ID) | 300 mA | 300 mA | Sets the maximum continuous current the device can carry; identical ratings ensure equivalent load-driving capability. |
| Drain-Source On-Resistance (RDS(on)) | 1.6 Ω @ VGS = 10 V | 1.6 Ω @ VGS = 10 V | Determines conduction losses and voltage drop; matching values preserve efficiency and thermal behavior. |
| Gate Threshold Voltage (VGS(th)) | 1.0 V to 2.5 V | 1.0 V to 2.5 V | Defines the gate voltage needed to turn the device on; identical ranges ensure compatible logic-level drive. |
| Gate-Source Voltage (VGS max) | ±20 V | ±20 V | Maximum safe gate drive voltage; matching limits protect the gate oxide under the same drive conditions. |
| Power Dissipation (PD) | 350 mW | 350 mW | Indicates thermal capability; identical ratings mean the same power handling in the application. |
| Input Capacitance (Ciss) | 50 pF | 50 pF | Affects switching speed and gate drive requirements; matching capacitance preserves dynamic performance. |
| Package / Mounting | SOT-23 Surface Mount | SOT-23 Surface Mount | Determines PCB footprint and assembly compatibility; identical packages allow direct drop-in replacement. |
| Channel Type | N-Channel | N-Channel | Defines polarity and circuit topology; matching channel type is essential for functional equivalence. |

Frequently asked questions
What is the difference between the 2N7002K and the 2N7002K-7?
The 2N7002K and 2N7002K-7 are the same N-channel enhancement-mode MOSFET die and electrical specification; the "-7" suffix denotes the manufacturer's tape-and-reel packaging option (7-inch reel) rather than a different device. Both are rated 60 V VDS, 300 mA continuous drain current, and are offered in the SOT-23 (TO-236) package.
Are the 2N7002K and 2N7002K-7 electrically identical?
Yes. The "-7" designation is a packaging/reel suffix, so the datasheet electrical characteristics such as VDS = 60 V, VGS(th) range, RDS(on), and drain current ratings are the same for both ordering codes.
Can the 2N7002K-7 be used as a drop-in replacement for the 2N7002K?
Yes, provided the board accepts the SOT-23 package and the reel quantity is acceptable for the assembly process. Since the die and electrical parameters are identical, the two ordering codes are functionally interchangeable in the same footprint.
What package do the 2N7002K and 2N7002K-7 use?
Both devices are supplied in the SOT-23 (also designated TO-236 or SC-59) surface-mount package, with the standard small-signal MOSFET pinout: gate, source, and drain on the three leads.
What are the key ratings of the 2N7002K and 2N7002K-7?
Verified datasheet ratings include VDS = 60 V, VGS = ±20 V, continuous drain current ID = 300 mA at 25 °C, and power dissipation around 350 mW in the SOT-23 package. RDS(on) is typically specified at VGS = 10 V and VGS = 4.5 V.
Why do distributors list the 2N7002K and 2N7002K-7 as separate part numbers?
Distributors separate them because the suffix encodes the packaging format and reel size, which affects minimum order quantity, inventory handling, and automated pick-and-place feeder setup, even though the semiconductor device itself is the same.
Which applications are suitable for the 2N7002K and 2N7002K-7?
Both are used as small-signal switching MOSFETs in level shifting, load switching, relay and LED driving, and low-current gate drive circuits where a 60 V, 300 mA N-channel device in SOT-23 is adequate.
