Engineering Selection Recommendations

Primary Recommendation: 2N7002-7-F (Diodes Incorporated)

The 2N7002-7-F is the direct successor to the 2N7002-7, manufactured by the same supplier with identical electrical specifications. This part maintains 60V Vdss, 115mA continuous drain current, and 7.5Ohm Rds On characteristics. The 2N7002-7-F is classified as Active with ROHS3 compliance, addressing the obsolescence status of the original part. Packaging is available in Cut Tape and Digi-Reel formats with 850,200 units in stock.

Secondary Recommendations (Electrical Equivalents):

The 2N7002L, 2N7002LT1G, and 2N7002LT3G (onsemi) maintain full electrical equivalence with reduced power dissipation ratings (200–225mW versus 370mW). These parts are Active with ROHS3 compliance and are suitable for applications where thermal performance is not a limiting factor. The 2N7002LT1H variant includes AEC-Q101 automotive qualification for applications requiring automotive-grade components.

The 2N7002-TP (Micro Commercial Co) provides electrical equivalence with 200mW power dissipation and is available in high-volume inventory (100,400 units).

Enhanced Performance Alternative: 2N7002E-T1-E3 (Vishay Siliconix)

The 2N7002E-T1-E3 exceeds the baseline specifications with 240mA continuous drain current, 3Ohm Rds On, and reduced input capacitance (21pF). This part is suitable for applications requiring improved current handling and switching performance while maintaining 60V voltage rating and SOT-23-3 package compatibility.

High-Current Alternative: 2N7002-TP-HF (Micro Commercial Co)

The 2N7002-TP-HF provides 340mA continuous drain current with 2.5Ohm Rds On, representing a significant performance upgrade. This part is appropriate for applications requiring higher current capacity within the same package footprint.

Not Recommended: 2N7002-G (onsemi)

The 2N7002-G is classified as Last Time Buy, indicating discontinued production. While electrically equivalent, this part should not be selected for new designs or long-term procurement.

Frequently Asked Questions (FAQ)

Q: Can the 2N7002-7 be directly replaced with the 2N7002-7-F?

A: Yes. The 2N7002-7-F is the direct active equivalent manufactured by Diodes Incorporated with identical electrical specifications (60V Vdss, 115mA Id, 7.5Ohm Rds On). The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant). Packaging options differ (Cut Tape/Digi-Reel versus Tape & Reel), but the component itself is electrically and mechanically interchangeable.

Q: What is the difference between the onsemi 2N7002L and 2N7002LT1G variants?

A: Both parts maintain identical electrical specifications (60V Vdss, 115mA Id, 7.5Ohm Rds On, 2.5V Vgs(th)). The primary differences are power dissipation ratings (200mW for 2N7002L versus 225mW for 2N7002LT1G) and packaging availability. The 2N7002LT1G is available in higher volume (360,300 units) and includes the automotive-qualified variant 2N7002LT1H with AEC-Q101 certification.

Q: Is the 2N7002-TP-HF a suitable substitute for the 2N7002-7?

A: The 2N7002-TP-HF is not a direct substitute. While both devices share the 60V Vdss rating and SOT-23-3 package, the 2N7002-TP-HF has significantly different electrical characteristics: 340mA continuous drain current (versus 115mA), 2.5Ohm Rds On (versus 7.5Ohm), and 1.08W power dissipation (versus 370mW). This part is suitable only for applications requiring higher current capacity and lower on-resistance.

Q: Can the 2N7002E-T1-E3 (Vishay) be used as a drop-in replacement?

A: The 2N7002E-T1-E3 is mechanically compatible (SOT-23-3 package) and electrically superior in most respects (240mA Id, 3Ohm Rds On, 21pF Ciss). However, it is not a true drop-in replacement due to enhanced performance characteristics. It is suitable for applications where improved current handling and reduced switching losses are beneficial, but circuit design should be reviewed to confirm compatibility with the lower on-resistance and reduced input capacitance.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS3 compliance is a regulatory requirement for components used in many markets, particularly Europe and Asia. The original 2N7002-7 is RoHS non-compliant, making it unsuitable for new designs or procurement in regulated markets. All recommended active substitutes (2N7002-7-F, 2N7002L, 2N7002LT1G, 2N7002-TP) are ROHS3 compliant, ensuring regulatory compliance for end-product applications.

Q: Are there packaging differences between substitute parts?

A: Yes. The 2N7002-7 is supplied in Tape & Reel (TR) format. Active substitutes are available in Cut Tape (CT) and Digi-Reel formats. The 2N7002LT1H and 2N7002-G do not specify packaging format in the provided data. All parts use the same SOT-23-3 (TO-236-3, SC-59) package footprint, ensuring PCB compatibility. Packaging format selection depends on assembly process requirements and volume.

Q: Which substitute offers the best thermal performance?

A: The 2N7002L and 2N7002-G offer the lowest power dissipation at 200mW, followed by 2N7002LT1G and 2N7002LT3G at 225mW. These parts are suitable for applications with thermal constraints. The 2N7002-TP-HF offers the highest power dissipation (1.08W) and is appropriate only for high-current applications where thermal management is addressed through circuit design.

Q: Is automotive qualification required for my application?

A: Automotive qualification (AEC-Q101) is required only for components used in automotive applications or supplied to automotive manufacturers. The 2N7002LT1H is the only substitute with explicit AEC-Q101 qualification. For non-automotive applications, this certification is not necessary, and other active equivalents are appropriate.
