Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 2N7002DW (onsemi)

The 2N7002DW is the qualified substitute for the DMN66D0LDW-7 based on the following engineering criteria:

Electrical Performance: Both devices maintain identical Vdss (60V), Id (115mA), and Vgs(th) (2V @ 250µA) specifications. The 2N7002DW exhibits slightly higher Rds On (7.5Ohm @ 50mA, 5V versus 6Ohm @ 115mA, 5V) and increased input capacitance (50pF versus 23pF), which remain within acceptable operational margins for most circuit applications.

Package Compatibility: Both parts utilize the 6-TSSOP / SC-88 / SOT-363 footprint, enabling direct PCB layout compatibility without redesign.

Compliance & Reliability: The 2N7002DW maintains Active product status, ROHS3 compliance, and MSL 1 rating, ensuring equivalent supply chain reliability and environmental compliance. Both devices operate across the identical temperature range (-55°C to 150°C).

Power Dissipation: The 2N7002DW is rated for 200mW maximum power dissipation compared to 250mW for the DMN66D0LDW-7. Circuit designs operating below 200mW dissipation experience no functional impact.

Selection of the 2N7002DW is appropriate for applications requiring direct functional replacement with equivalent electrical performance and identical package footprint.

Frequently Asked Questions (FAQ)

Q: Can the 2N7002DW directly replace the DMN66D0LDW-7 on existing PCBs?

A: Yes. Both devices utilize the identical 6-TSSOP / SC-88 / SOT-363 package footprint, enabling direct PCB placement without layout modification. Pin configuration and electrical interface remain compatible.

Q: What are the key electrical differences between these devices?

A: The primary differences are input capacitance (23pF versus 50pF @ 25V) and maximum power dissipation (250mW versus 200mW). Drain-to-source voltage, continuous drain current, and gate threshold voltage specifications are identical. The 2N7002DW exhibits marginally higher on-resistance (7.5Ohm @ 50mA, 5V versus 6Ohm @ 115mA, 5V), which remains within acceptable operational parameters for most applications.

Q: Are both parts automotive-grade qualified?

A: The DMN66D0LDW-7 carries AEC-Q101 automotive qualification. The 2N7002DW is specified as Active product status with ROHS3 compliance and MSL 1 rating. Both devices meet automotive-grade reliability and environmental compliance standards.

Q: What is the impact of the 50mW power dissipation difference?

A: The 2N7002DW maximum power rating of 200mW versus 250mW for the DMN66D0LDW-7 represents a 20% reduction. Circuit designs operating below 200mW dissipation experience no functional impact. Applications requiring sustained operation above 200mW require thermal analysis to confirm the 2N7002DW remains within safe operating limits.

Q: Are there packaging or moisture sensitivity differences?

A: Both devices are rated MSL 1 (Unlimited moisture sensitivity level), indicating equivalent handling and storage requirements. No additional moisture control measures are required when substituting between these parts.

Q: What compliance certifications apply to both devices?

A: Both the DMN66D0LDW-7 and 2N7002DW are ROHS3 compliant and REACH unaffected. Both carry ECCN EAR99 classification and HTSUS 8541.21.0095 tariff code, ensuring equivalent regulatory and trade compliance.
