FDSS2407 MOSFET Equivalent & Substitute Parts

Part Overview

The FDSS2407 is a dual N-channel MOSFET manufactured by onsemi, rated for 62V drain-to-source voltage with 3.3A continuous drain current. This device is configured as a logic-level gate MOSFET in a surface-mount 8-SOIC package and qualifies for automotive applications under AEC-Q101 certification.

The FDSS2407 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDSS2407 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-source voltage rating (Vdss) must equal or exceed 62V
• Continuous drain current (Id) must equal or exceed 3.3A at 25°C
• On-state resistance (Rds On) must not exceed 110mOhm at specified conditions
• Gate threshold voltage (Vgs(th)) must be compatible with logic-level gate operation
• Gate charge (Qg) and input capacitance (Ciss) must support existing gate drive circuitry

Mechanical Compatibility Criteria:

• Package type must be 8-SOIC surface mount
• Configuration must be dual N-channel (2 N-CH)
• Physical dimensions must match 0.154" width (3.90mm)

Compliance and Certification Criteria:

• RoHS3 compliance required
• Moisture sensitivity level (MSL) of 1 or better
• Automotive-grade qualification preferred for applications requiring AEC-Q101 certification

The FDSS2407-SB82086P is identified as a substitute part based on matching package configuration, surface-mount technology, and compliance requirements, with electrical parameters within acceptable operating ranges for the application.

FDSS2407-SB82086P Substitution Considerations:

The FDSS2407-SB82086P is an active product from onsemi and maintains mechanical and electrical compatibility with the obsolete FDSS2407 across package configuration, mounting technology, and dual N-channel topology. Both devices are RoHS3 compliant with MSL rating of 1, supporting equivalent handling and storage requirements.

The primary electrical difference is the drain-to-source voltage rating: the substitute is rated for 60V compared to the original 62V specification. This 2V reduction in maximum voltage rating must be evaluated against the actual operating voltage margins in the target application. For applications operating at voltages below 60V, the substitute provides equivalent performance. For applications requiring the full 62V rating, alternative parts with matching or higher voltage specifications must be identified.

Both devices share the same base product number (FDSS24) and 8-SOIC package footprint, ensuring PCB layout compatibility and assembly process alignment. The substitute's active product status provides improved long-term availability compared to the obsolete original part.

Compliance with automotive-grade requirements and AEC-Q101 qualification should be verified for the substitute part if the original application mandates these certifications.

Frequently Asked Questions (FAQ)

Q: Can the FDSS2407-SB82086P be used as a direct replacement for the FDSS2407?

A: The FDSS2407-SB82086P is mechanically and functionally compatible for most applications. The substitute maintains the same 8-SOIC package footprint, dual N-channel configuration, and 3.3A current rating. The key difference is the 60V voltage rating versus the original 62V specification. Direct substitution is valid for applications operating below 60V. Applications requiring the full 62V rating require evaluation of voltage margins and potential alternative parts.

Q: Are there any package or footprint differences between these parts?

A: Both the FDSS2407 and FDSS2407-SB82086P use the 8-SOIC surface-mount package with 0.154" (3.90mm) width. PCB footprints and assembly processes are compatible without modification.

Q: What compliance certifications apply to the substitute part?

A: The FDSS2407-SB82086P is RoHS3 compliant and carries MSL rating of 1 (unlimited moisture sensitivity level). Automotive-grade qualification and AEC-Q101 certification status for the substitute should be confirmed with the manufacturer if these requirements apply to the target application.

Q: How does the 60V rating of the substitute affect circuit design?

A: The 2V reduction in maximum drain-to-source voltage rating affects the absolute maximum voltage the device can withstand. Applications with voltage transients or overvoltage conditions near the 62V threshold require analysis to confirm operation remains within the 60V limit of the substitute. Applications with adequate voltage margin below 60V are unaffected.

Q: Is the FDSS2407-SB82086P currently available?

A: Yes, the FDSS2407-SB82086P is classified as an active product with current inventory availability, unlike the obsolete FDSS2407. This provides improved supply chain continuity for new production and ongoing support.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by drain-to-source voltage (Vdss), continuous drain current (Id), on-state resistance (Rds On), gate threshold voltage (Vgs(th)), gate charge (Qg), and input capacitance (Ciss). The substitute must meet or exceed the original specifications for these parameters to ensure equivalent circuit performance.
