Power Dissipation (Max) must equal or exceed 200mW
Gate-Source Voltage (Vgs) range must accommodate ±20V
Threshold Voltage (Vgs(th)) must be within acceptable switching range

Mechanical Compatibility Requirements:

Mounting type must be Surface Mount

Engineering Selection Recommendations

Primary Recommendation: 2N7002W-7-F (Diodes Incorporated)

The 2N7002W-7-F is the direct electrical and mechanical equivalent of the 2N7002W-7. It maintains identical electrical specifications (60V Vdss, 115mA Id, 7.5Ohm Rds On, 200mW power dissipation) and is packaged in the same SOT-323 configuration. The primary distinction is RoHS3 compliance and active product status. This part is suitable for direct replacement in existing designs without layout or thermal modifications.

Secondary Recommendation: 2N7002LT1G (onsemi)

The 2N7002LT1G provides electrical equivalence with identical 60V Vdss and 115mA Id ratings. It is packaged in SOT-23-3 (TO-236-3), which requires PCB layout modification but maintains the same pin count and functionality. This part is RoHS3 compliant and actively supported. Selection of this part is appropriate when PCB redesign is feasible or when SOT-23-3 packaging is preferred for manufacturing reasons.

Alternative Recommendation: 2N7002T (onsemi)

The 2N7002T matches the electrical specifications of the original part (60V Vdss, 115mA Id, 7.5Ohm Rds On, 200mW power dissipation) and is packaged in SC-89-3 (SOT-490). This ultra-compact package is suitable for space-constrained applications. RoHS3 compliance and active product status support long-term availability.

Higher Current Alternatives: 2N7002BKW,115 and 2N7002KT1G

These parts exceed the minimum current requirement (310mA and 320mA respectively) and provide improved thermal performance (275mW and 300mW). They are suitable for applications requiring design margin or where thermal management is a concern. Both are RoHS3 compliant and actively supported. The 2N7002BKW,115 maintains SOT-323 packaging, while 2N7002KT1G uses SOT-23-3.

Not Recommended for New Designs: 2N7002PW,115

Although electrically suitable, this part carries "Not For New Designs" status and should be avoided in new product development.

Frequently Asked Questions (FAQ)

Q: Can I use 2N7002W-7-F as a direct replacement for 2N7002W-7?

A: Yes. The 2N7002W-7-F is electrically and mechanically identical to the 2N7002W-7. Both are rated for 60V Vdss, 115mA continuous drain current, and 200mW power dissipation in SOT-323 packaging. No circuit modifications are required. The primary difference is RoHS3 compliance and active product status.

Q: What is the difference between SOT-323 and SOT-23-3 packages?

A: SOT-323 (SC-70) and SOT-23-3 (SC-59, TO-236-3) are both three-pin surface mount packages for MOSFETs, but differ in physical dimensions and land pattern. SOT-323 is smaller and more compact. Substitution between these packages requires PCB layout modification and updated footprints. Pin functionality remains identical for N-Channel MOSFET operation.

Q: Can I use a higher current rated part like 2N7002BKW,115 (310mA) instead of the 115mA rated 2N7002W-7?

A: Yes. Higher current-rated parts are suitable substitutes when they maintain the same voltage rating (60V Vdss) and package compatibility. The 2N7002BKW,115 provides additional current capacity and improved thermal performance (275mW vs. 200mW), making it suitable for applications requiring design margin. No circuit modifications are necessary.

Q: Is RoHS3 compliance important for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and many other markets. All recommended active substitutes (2N7002W-7-F, 2N7002LT1G, 2N7002T, 2N7002BKW,115, 2N7002KT1G) are RoHS3 compliant. If your application requires RoHS3 compliance, avoid the original 2N7002W-7 (non-compliant) and select from the compliant alternatives.

Q: What is the operating temperature range for these parts?

A: All listed substitutes operate across the -55°C to 150°C junction temperature range, matching the original 2N7002W-7 specification. This range supports industrial and automotive applications. The 2N7002 (UMW) and 2N7002T (onsemi) specify maximum junction temperature of 150°C without lower limit specification; verify against your thermal design requirements.

Q: Can I use 2N7002-TP (SOT-23) instead of the SOT-323 packaged original?

A: Yes, with PCB layout modification. The 2N7002-TP maintains identical electrical specifications (60V Vdss, 115mA Id, 200mW power dissipation) and is RoHS3 compliant. However, SOT-23 packaging requires a different footprint than SOT-323. This substitution is appropriate when PCB redesign is planned or when SOT-23 packaging is preferred for manufacturing compatibility.

Q: What does "Not For New Designs" status mean for 2N7002PW,115?

A: "Not For New Designs" indicates that the manufacturer (Nexperia) is not recommending this part for new product development, though it remains available for existing designs. While electrically suitable, this part should be avoided in new designs to ensure long-term supply continuity and manufacturer support. Select 2N7002BKW,115 (active status) as the preferred Nexperia alternative.

Q: Are there any thermal considerations when substituting these parts?

A: Yes. Power dissipation ratings vary among substitutes: the original 2N7002W-7 dissipates 200mW, while alternatives range from 200mW to 350mW. Higher power dissipation ratings provide thermal margin in applications with continuous current flow. Verify that your PCB thermal design accommodates the selected part's power dissipation. Parts with lower Rds On values (1.6Ohm vs. 7.5Ohm) generate less heat at equivalent current levels.

Q: Which substitute offers the best thermal performance?

A: The 2N7002E-T1-E3 (Vishay Siliconix) offers the highest power dissipation rating (350mW) and lowest Rds On (3Ohm @ 250mA, 10V), providing superior thermal performance. However, it also has the highest continuous drain current rating (240mA). For applications requiring maximum thermal margin with the original 115mA current specification, 2N7002BKW,115 or 2N7002KT1G provide improved thermal performance (275mW and 300mW respectively) with lower Rds On values.
