A: 2N7002K-7 (Diodes Incorporated) provides 380mA continuous drain current with 2 Ohm Rds(on) @ 500mA/10V. 2N7002K (Good-Ark Semiconductor) and 2N7002K-T1-E3 (Vishay Siliconix) provide 300mA with 2 Ohm Rds(on) characteristics. All maintain 60V Vdss and SOT-23-3 packaging.

Q5: What is the operating temperature range compatibility for substitute parts?

A: All substitute parts operate across -55°C to 150°C junction temperature range, matching the SN7002N E6433 specification. 2N7002K (Good-Ark Semiconductor) extends to -55°C to 175°C for high-temperature applications.

Q6: Are substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH Unaffected, meeting regulatory requirements for new designs and production applications.

Q7: What is the significance of product status (Active vs. Obsolete) in component selection?

A: The SN7002N E6433 is classified as Obsolete, indicating discontinued manufacturing and limited availability. All substitute parts are Active status products with ongoing production and supply chain availability, ensuring design continuity and long-term component sourcing for production and maintenance applications.

Q8: Can lower current-rated substitutes (2N7002-7-F at 115mA) be used in applications designed for 200mA?

A: No. Lower current-rated parts do not meet the 200mA continuous drain current specification. Selection of substitute parts must ensure the continuous drain current rating meets or exceeds application requirements.
