Key Parameters

Substitute Part Grouping Explanation

Substitution of the NDS7002A_D87Z is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Drain to Source Voltage (Vdss): 60V minimum
• Continuous Drain Current (Id): 280mA or greater
• Rds On (Max) @ 10V: 2Ohm or lower
• Vgs(th) (Max): 2.5V or lower
• Vgs (Max): ±20V
• Input Capacitance (Ciss): 50pF or lower
• Power Dissipation (Max): 300mW or greater
• Operating Temperature Range: -65°C to 150°C or equivalent

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount
• Package / Case: SOT-23-3, TO-236-3, or SC-59

All substitute parts listed meet or exceed these electrical and mechanical parameters, ensuring functional equivalence in applications designed for the NDS7002A_D87Z.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: NDS7002A

The NDS7002A from onsemi is the direct equivalent to the NDS7002A_D87Z. It maintains identical electrical specifications and is currently in active product status. This part is ROHS3 compliant and available in high volume (141,200 pieces in stock). Selection of this part eliminates any performance variation and is the preferred choice for direct replacement.

Secondary Recommendations: 2N7002K-T1-GE3 and DMN601K-7

Both the 2N7002K-T1-GE3 (Vishay Siliconix) and DMN601K-7 (Diodes Incorporated) are active products that meet or exceed all electrical parameters of the NDS7002A_D87Z. The 2N7002K-T1-GE3 features reduced input capacitance (30pF versus 50pF), which may provide performance benefits in high-frequency switching applications. The DMN601K-7 extends the lower operating temperature limit to -65°C, matching the original part specification. Both are ROHS3 compliant and available in high volume.

Alternative Consideration: 2N7002K-7

The 2N7002K-7 from Diodes Incorporated exceeds the continuous drain current specification (380mA versus 280mA) and power dissipation (370mW versus 300mW), providing additional design margin. This part is active and ROHS3 compliant. However, the lower operating temperature limit (-55°C) is narrower than the original specification.

Not Recommended for New Designs: 2N7002P,215

The 2N7002P,215 from Nexperia USA Inc. is classified as "Not For New Designs" and should not be selected for new applications, despite meeting electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can the NDS7002A_D87Z be directly replaced with NDS7002A?

A: Yes. The NDS7002A is the direct equivalent with identical electrical specifications. Both parts are N-Channel MOSFETs with 60V Vdss, 280mA continuous drain current, 2Ohm Rds On, and SOT-23-3 packaging. The primary difference is product status: NDS7002A is active while NDS7002A_D87Z is obsolete.

Q: What is the minimum drain current required for a substitute part?

A: The substitute part must support a continuous drain current of 280mA or greater at 25°C. All listed substitutes meet this requirement, with some exceeding it (2N7002K-7 at 380mA, 2N7002P,215 at 360mA, 2N7002K-T1-GE3 at 300mA, DMN601K-7 at 300mA).

Q: Are all substitute parts available in SOT-23-3 packaging?

A: Yes. All substitute parts are available in SOT-23-3 surface mount packaging, which is mechanically compatible with the original NDS7002A_D87Z. The 2N7002P,215 is also available in TO-236AB, which is functionally equivalent to SOT-23-3.

Q: What is the significance of the lower operating temperature limit difference?

A: The NDS7002A_D87Z and DMN601K-7 both specify -65°C as the lower operating temperature limit. The 2N7002K-7, 2N7002K-T1-GE3, and 2N7002P,215 specify -55°C. If the application requires operation below -55°C, only NDS7002A, DMN601K-7, or the original part should be used.

Q: Why is 2N7002P,215 marked "Not For New Designs"?

A: The 2N7002P,215 carries a "Not For New Designs" status from the manufacturer, indicating it is in the end-of-life phase. While it meets all electrical and mechanical requirements for substitution, it should not be selected for new product development due to potential future availability constraints.

Q: Does input capacitance variation affect substitution compatibility?

A: Input capacitance (Ciss) affects switching speed and gate drive requirements. The NDS7002A_D87Z specifies 50pF maximum. The 2N7002K-T1-GE3 specifies 30pF, which is lower and may improve switching performance in high-frequency applications. All other substitutes specify 50pF, matching the original specification exactly.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts (NDS7002A, 2N7002K-7, 2N7002K-T1-GE3, DMN601K-7) are ROHS3 compliant. The 2N7002P,215 is also ROHS3 compliant but carries "Not For New Designs" status. The original NDS7002A_D87Z does not specify RoHS status.

Q: What is the difference between Rds On specifications at different gate voltages?

A: All parts specify Rds On (Max) of 2Ohm at 500mA drain current and 10V gate voltage. The 2N7002P,215 specifies a lower Rds On of 1.6Ohm at the same conditions, providing lower on-state resistance and reduced power dissipation. This represents an improvement over the original specification.
