2N7002WKX-13 Equivalent & Substitute Parts

Part Overview

The 2N7002WKX-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 60V drain-to-source voltage with 115mA continuous drain current at 25°C. The device is housed in a SOT-323 (SC-70) surface mount package and dissipates a maximum of 200mW. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution of the 2N7002WKX-13 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

FET Type: N-Channel
Drain-to-Source Voltage (Vdss): 60V minimum
Package: SOT-323 (SC-70) surface mount
Gate-Source Voltage (Vgs): ±20V maximum
Input Capacitance (Ciss): 50pF @ 25V
Power Dissipation: 200mW (Ta)
RoHS3 Compliance

Allowable Variation Parameters:

Continuous Drain Current (Id): Equal to or greater than 115mA
On-Resistance (Rds On): Lower values are acceptable
Operating Temperature Range: Equal to or greater than specified range
Product Status: Active status preferred for long-term availability

Substitute parts must satisfy all critical matching parameters while maintaining or exceeding performance in allowable variation parameters.

Engineering Selection Recommendations

DMN601WK-7 (Diodes Incorporated)

The DMN601WK-7 is a direct substitute from the same manufacturer with identical voltage and package specifications. This part exceeds the drain current requirement (300mA vs. 115mA) and maintains all critical electrical parameters. The lower on-resistance (2Ohm @ 500mA, 10V vs. 7.5Ohm @ 50mA, 5V) provides improved performance characteristics. Extended operating temperature range (-65°C to 150°C) offers broader environmental compatibility. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance and identical package footprint enable direct PCB substitution.

2N7002W (Diotec Semiconductor)

The 2N7002W maintains identical electrical specifications for voltage, current, and power dissipation. This part shares the same base product number (2N7002) and package configuration. Active product status provides ongoing availability. ROHS3 compliance and identical SOT-323 package enable direct substitution. Cross-manufacturer sourcing provides supply redundancy. On-resistance specification (13.5Ohm @ 500mA, 10V) differs from the main part but remains within acceptable operating parameters for equivalent circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the DMN601WK-7 replace the 2N7002WKX-13 in all applications?

A: Yes. The DMN601WK-7 meets all critical electrical parameters (60V Vdss, SOT-323 package, ±20V Vgs, 50pF Ciss) and exceeds the drain current specification. The identical package and superior performance characteristics ensure compatibility in all circuits designed for the 2N7002WKX-13.

Q: What is the primary difference between the DMN601WK-7 and 2N7002W substitutes?

A: The DMN601WK-7 provides higher drain current capability (300mA vs. 115mA) and lower on-resistance, offering enhanced performance. The 2N7002W maintains identical current and power specifications to the original part. Both are electrically and mechanically compatible.

Q: Are there any package or footprint differences between these substitutes?

A: No. All three parts (2N7002WKX-13, DMN601WK-7, and 2N7002W) use the SOT-323 (SC-70) surface mount package with identical pin configuration and PCB footprint. Direct board-level substitution is possible without layout modifications.

Q: Why is the 2N7002WKX-13 classified as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The substitute parts listed (DMN601WK-7 and 2N7002W) are active products with confirmed ongoing manufacturing and supply availability.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. Both the DMN601WK-7 and 2N7002W are ROHS3 compliant, matching the compliance status of the original 2N7002WKX-13.

Q: Can I use the DMN601WK-7 in circuits requiring exactly 115mA drain current?

A: Yes. The DMN601WK-7 is rated for 300mA continuous drain current, which exceeds the 115mA requirement. The part operates safely at lower current levels within its rated specifications.

Q: What is the difference in on-resistance between the substitutes?

A: The DMN601WK-7 specifies 2Ohm @ 500mA, 10V, while the 2N7002W specifies 13.5Ohm @ 500mA, 10V. Lower on-resistance reduces power dissipation and heat generation. Both values are acceptable for circuits designed around the original 7.5Ohm specification.
