Key electrical and mechanical differences between the two devices
| Parameter | 2N7002K | 2N7002,215 | Why it matters |
|---|---|---|---|
| Drain-Source Voltage (Vds) | 60 V | 60 V | Maximum voltage the device can block; must meet or exceed circuit voltage for safe operation. |
| Continuous Drain Current (Id) | 300 mA | 300 mA | Defines the maximum load current the MOSFET can handle continuously without damage. |
| Drain-Source On-Resistance (Rds(on)) | 1.6 Ω @ Vgs=10V, Id=500mA | 5 Ω @ Vgs=10V, Id=500mA | Lower on-resistance reduces conduction losses and heat generation in switching applications. |
| Gate Threshold Voltage (Vgs(th)) | 1.0 V to 2.5 V | 1.0 V to 2.5 V | Determines the minimum gate voltage needed to turn on the MOSFET; affects logic-level compatibility. |
| Gate-Source Voltage (Vgs) Max | ±20 V | ±20 V | Maximum safe gate drive voltage; exceeding it can permanently damage the gate oxide. |
| Power Dissipation (Pd) | 350 mW | 830 mW | Indicates how much power the package can dissipate; higher values allow more current or lower Rds(on) operation. |
| Input Capacitance (Ciss) | 50 pF | 50 pF | Affects switching speed and gate drive requirements; lower capacitance enables faster switching. |
| Package / Mounting | SOT-23 Surface Mount | SOT-23 Surface Mount | Physical form factor and mounting type must match the PCB footprint for direct replacement. |
| Operating Junction Temperature (Tj) | -55 °C to +150 °C | -55 °C to +150 °C | Defines the safe thermal operating range; must cover the application's ambient and self-heating conditions. |

Frequently asked questions
What are the key differences between the 2N7002K and the 2N7002,215?
The 2N7002K is a specific part number variant of the 2N7002 N-channel MOSFET, while the 2N7002,215 is a distinct ordering code from Nexperia (formerly NXP) for the same 2N7002 MOSFET family. The primary differences lie in the manufacturer, package marking, and specific datasheet parameters such as drain-source on-resistance (RDS(on)) and gate threshold voltage (VGS(th)) ranges. The 2N7002K is often associated with a specific manufacturer's version (e.g., ON Semiconductor/Fairchild) with its own guaranteed limits, whereas the 2N7002,215 is the Nexperia version in a SOT-23 package with its own set of verified specifications.
Are the 2N7002K and 2N7002,215 pin-to-pin compatible?
Yes, both the 2N7002K and the 2N7002,215 are typically offered in the standard SOT-23 (TO-236AB) surface-mount package with the same pinout: Gate (Pin 1), Source (Pin 2), and Drain (Pin 3). This means they are pin-to-pin compatible in terms of footprint and pin function, allowing them to be placed on the same PCB land pattern.
Can the 2N7002K and 2N7002,215 be used interchangeably in a design?
They can be used interchangeably only after verifying that the electrical parameter differences do not affect the target application. Key parameters to compare include drain-source voltage (VDS), continuous drain current (ID), power dissipation (PD), RDS(on) at the specific gate-source voltage (VGS) used in the circuit, and VGS(th) limits. For example, if a design relies on a maximum RDS(on) that is guaranteed by one part but not the other, direct substitution may not be safe without validation.
What is the maximum drain-source voltage (VDS) for the 2N7002K and 2N7002,215?
Both the 2N7002K and the 2N7002,215 have a maximum drain-source voltage (VDS) rating of 60 V. This is a standard rating for the 2N7002 family and is consistent across verified manufacturer datasheets for these specific part numbers.
What is the continuous drain current (ID) rating for the 2N7002K and 2N7002,215?
The continuous drain current (ID) rating for both the 2N7002K and the 2N7002,215 is typically 115 mA at an ambient temperature of 25°C, with a pulsed drain current (IDM) rating of 800 mA. These values are subject to the specific manufacturer's datasheet and test conditions, but they are the commonly verified limits for these parts.
How does the gate threshold voltage (VGS(th)) compare between the 2N7002K and 2N7002,215?
The gate threshold voltage (VGS(th)) for both the 2N7002K and the 2N7002,215 is typically specified with a range of 1.0 V to 2.5 V at a drain current of 250 µA and VDS = VGS. However, the exact minimum, maximum, and test conditions can vary slightly between manufacturers. Designers should consult the specific datasheet for the exact part number being used to confirm the guaranteed limits.
What is the typical RDS(on) for the 2N7002K and 2N7002,215?
The typical RDS(on) for both the 2N7002K and the 2N7002,215 is approximately 1.2 Ω to 2.0 Ω at VGS = 10 V and ID = 500 mA, and higher at VGS = 4.5 V (often around 2.0 Ω to 3.0 Ω). The maximum guaranteed RDS(on) values differ between manufacturers and part variants, so the specific datasheet for the 2N7002K or 2N7002,215 must be consulted for worst-case design calculations.
Which manufacturers produce the 2N7002K and 2N7002,215?
The 2N7002K is commonly manufactured by ON Semiconductor (formerly Fairchild Semiconductor) and other second-source suppliers. The 2N7002,215 is a specific ordering code from Nexperia (formerly NXP Semiconductors). Both are widely available through authorized distributors such as DigiKey, Mouser, and TTI. Always verify the manufacturer and part number suffix when ordering to ensure the correct variant is received.
