Substitute parts must match all specified electrical parameters and maintain identical package and mounting characteristics to ensure form, fit, and functional compatibility within existing PCB designs and thermal management systems.

Parameter Comparison

Engineering Selection Recommendations

The FDPC8014AS manufactured by Fairchild Semiconductor represents a direct electrical and mechanical equivalent to the obsolete onsemi FDPC8014AS. All critical electrical parameters—including voltage rating, current capability, on-resistance, gate characteristics, and thermal operating range—are identical across both variants.

Product Status Consideration: The onsemi variant carries obsolete status, while the Fairchild Semiconductor variant maintains active product status. The active status of the Fairchild Semiconductor FDPC8014AS provides improved long-term availability and supply chain continuity for ongoing production and design support.

Compliance and Certification: The onsemi FDPC8014AS is certified as ROHS3 compliant, REACH unaffected, and carries MSL Level 1 (unlimited moisture sensitivity). The Fairchild Semiconductor variant does not specify these certifications in the provided data. Design teams must verify compliance requirements against applicable regulatory standards and supply chain specifications before final component selection.

Packaging Consideration: The onsemi variant is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the Fairchild Semiconductor variant is supplied in bulk packaging. Packaging selection depends on production volume requirements, automated assembly capabilities, and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can the Fairchild Semiconductor FDPC8014AS directly replace the onsemi FDPC8014AS in existing designs?

A: Yes. Both variants share identical electrical specifications across all critical parameters: 25V Vdss rating, 20A/40A continuous drain current, 3.8mOhm on-resistance, and matching gate and capacitance characteristics.
