2N7002 vs 2N7002-7-F

The 2N7002-7-F is a specific manufacturer part number from Diodes Incorporated that designates a 2N7002 N-channel MOSFET in a SOT-23 package with a particular packaging option, typically 7-inch tape and reel. The generic 2N7002 refers to the base industry-standard device type, which may be offered by multiple manufacturers with varying packaging, labeling, and minor parameter tolerances. Electrically, both are 60 V, 115 mA N-channel enhancement-mode MOSFETs, but the -7-F suffix indicates Diodes Incorporated's specific ordering and packaging variant.

Yes, in most cases they are electrically interchangeable because both conform to the same 2N7002 industry specification: VDS = 60 V, ID = 115 mA, RDS(on) typically around 1.2 Ω to 7.5 Ω depending on VGS, and VGS(th) between 1 V and 2.5 V. However, designers should verify the specific manufacturer datasheet for the generic 2N7002 being used, as minor differences in RDS(on), capacitance, and threshold voltage may exist between vendors.

The 2N7002-7-F from Diodes Incorporated is supplied in the SOT-23 (TO-236) surface-mount package. The standard 2N7002 is also commonly available in SOT-23, though other package options such as SOT-323 or through-hole TO-92 may exist from different manufacturers. The -7-F suffix specifically denotes tape and reel packaging with a 7-inch reel diameter.

Per the Diodes Incorporated datasheet, the 2N7002-7-F has a drain-source voltage (VDS) of 60 V, a continuous drain current (ID) of 115 mA at 25°C, a power dissipation (PD) of 200 mW at 25°C, and a gate-source voltage (VGS) range of ±20 V. RDS(on) is typically 1.2 Ω at VGS = 10 V and 2.0 Ω at VGS = 4.5 V. These ratings are consistent with the industry-standard 2N7002 specification.

In most SOT-23 applications, yes, provided the electrical parameters of the original 2N7002 meet or exceed the circuit requirements. Because the 2N7002 is a generic industry part number, different manufacturers may have slightly different RDS(on), input capacitance, and switching characteristics. A direct drop-in replacement is generally acceptable for low-frequency switching and level-shifting applications, but high-frequency or precision analog designs should compare the specific datasheets.

The "-7-F" suffix is a Diodes Incorporated ordering code. "7" indicates the tape and reel packaging size (7-inch reel), and "F" indicates the lead-free (RoHS-compliant) finish. The base part number 2N7002 identifies the device type. This suffix does not change the electrical characteristics of the MOSFET; it only specifies packaging and environmental compliance.

The 2N7002-7-F from Diodes Incorporated is RoHS compliant and lead-free, as indicated by the "F" suffix in the ordering code. The RoHS status of a generic 2N7002 depends on the specific manufacturer and ordering variant. Many modern 2N7002 devices are RoHS compliant, but designers should confirm the compliance status on the manufacturer's datasheet or distributor listing for the exact part number being used.

Both devices are commonly used for low-power switching applications such as level shifting, small-signal amplification, relay or LED driving, and interfacing logic circuits with higher-voltage loads. Their 60 V rating and low threshold voltage make them suitable for battery-powered and portable electronics. The 2N7002-7-F is particularly suited for automated surface-mount assembly due to its tape and reel packaging.
