FC6946010R MOSFET Equivalent & Substitute Parts

Part Overview

The FC6946010R is a dual N-channel MOSFET array manufactured by Panasonic Electronic Components, designed for low-power switching applications. This device features a 60V drain-to-source voltage rating, 100mA continuous drain current capability, and logic-level gate drive characteristics. The component is housed in a surface-mount SSMini6-F3-B package (SOT-563/SOT-666).

The FC6946010R is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement. Substitute parts must maintain electrical compatibility across critical parameters including voltage ratings, current handling, gate threshold characteristics, and thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FC6946010R is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain-to-Source Voltage (Vdss): 60V minimum
• Continuous Drain Current (Id): 100mA minimum at 25°C
• Gate Threshold Voltage (Vgs(th)): 1.5V maximum at 1µA
• On-State Resistance (Rds On): 12 Ohm maximum at specified conditions
• Configuration: Dual N-channel topology
• Package: SOT-563 or SOT-666 surface-mount form factor
• Logic-level gate drive capability

The substitute part KFC6946010R from Nuvoton Technology Corporation meets the core electrical specifications for voltage and current ratings. Substitution is valid when the alternative device maintains or exceeds the performance envelope defined by these parameters while maintaining mechanical compatibility with the original package footprint.

Engineering Selection Recommendations

Product Status Consideration: The FC6946010R is classified as obsolete, while the KFC6946010R substitute is listed as active. Selection of the active substitute part ensures continued availability and manufacturing support for new designs and production replenishment.

Compliance and Certification: The original FC6946010R carries RoHS compliance certification. When selecting the KFC6946010R as a substitute, verification of equivalent compliance status with applicable regulatory requirements is necessary for applications subject to environmental and hazardous substance restrictions.

Electrical Compatibility: Both devices share the same 60V Vdss rating and dual N-channel configuration. The KFC6946010R maintains electrical compatibility for applications designed around the FC6946010R specifications. Complete datasheet review of the substitute part is required to confirm all secondary electrical parameters align with circuit requirements.

Inventory and Supply Chain: The FC6946010R maintains 40,400 pieces in current inventory stock. The KFC6946010R substitute has 1,113 pieces available. Selection between the original and substitute should account for immediate availability requirements and long-term supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can the KFC6946010R directly replace the FC6946010R in existing designs?

A: The KFC6946010R shares the same 60V Vdss rating and dual N-channel configuration as the FC6946010R. Direct substitution is valid when the substitute part meets or exceeds all electrical specifications required by the original circuit design. Complete datasheet comparison is required before implementation.

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

A: Substitution compatibility is determined by: Drain-to-Source Voltage (Vdss) of 60V or higher, Continuous Drain Current (Id) of 100mA or higher at 25°C, Gate Threshold Voltage (Vgs(th)) of 1.5V or lower at 1µA, On-State Resistance (Rds On) of 12 Ohm or lower at specified conditions, and dual N-channel configuration. Package type must remain SOT-563 or SOT-666 surface-mount.

Q: Are there package compatibility concerns between the original and substitute parts?

A: Both the FC6946010R and KFC6946010R utilize surface-mount packaging. Mechanical compatibility depends on confirmation that the substitute part uses an identical or footprint-compatible package variant. Package designation verification is required before PCB layout finalization.

Q: What compliance certifications should be verified for the substitute part?

A: The original FC6946010R is RoHS compliant. When selecting the KFC6946010R substitute, confirmation of equivalent RoHS compliance status and any other applicable regulatory certifications (REACH, ECCN, HTSUS classification) is necessary for applications subject to environmental and trade compliance requirements.

Q: How does the product status difference affect substitution decisions?

A: The FC6946010R is obsolete while the KFC6946010R is active. Active product status indicates ongoing manufacturer support, continued availability, and potential for long-term supply chain stability. Obsolete status indicates limited future availability and potential discontinuation of the original part.
