Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDMS3600S is determined by the following critical electrical and mechanical parameters:

Voltage Rating: Both the main part and substitute must operate at 25V Drain to Source Voltage (Vdss) to ensure compatibility with existing circuit designs.

Configuration: The dual N-channel (2 N-Channel) configuration must be maintained to preserve circuit topology and pin functionality.

Current Capability: The substitute must support continuous drain current ratings of 20A or higher at 25°C to meet or exceed the original 15A/30A specification.

Package Type: Surface mount packaging with Tape & Reel delivery is required for manufacturing compatibility.

Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained for regulatory and supply chain requirements.

Moisture Sensitivity: MSL 1 rating ensures handling and storage compatibility with existing logistics infrastructure.

The FDPC8016S meets all substitution criteria through equivalent voltage rating, dual N-channel configuration, superior current handling (20A/35A), maintained compliance certifications, and compatible surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can the FDPC8016S directly replace the FDMS3600S in existing designs?

A: The FDPC8016S is electrically compatible as a substitute. Both parts share 25V Vdss rating, dual N-channel configuration, and surface mount packaging. The FDPC8016S provides higher continuous drain current (20A/35A), making it suitable for applications originally designed for the FDMS3600S (15A/30A). Physical package differences (8PQFN versus 8-PowerWDFN) require PCB layout verification.

Q: What are the key differences between the FDMS3600S and FDPC8016S?

A: The primary differences are part status (obsolete versus active), package designation (8PQFN versus 8-PowerWDFN), current rating (15A/30A versus 20A/35A), and available parametric data. Both maintain identical voltage rating, configuration, compliance certifications, and moisture sensitivity level.

Q: Are there any compliance or regulatory concerns with substitution?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Substitution does not introduce regulatory compliance issues.

Q: How does the package difference affect PCB design?

A: The FDMS3600S uses 8PQFN packaging while the FDPC8016S uses 8-PowerWDFN packaging. These are distinct package types with different footprints and thermal characteristics. PCB layout, land pattern, and thermal management design must be updated to accommodate the substitute package.

Q: Is the FDPC8016S available in the same delivery format?

A: Yes. Both parts are supplied in Tape & Reel (TR) format, maintaining compatibility with automated assembly processes and existing supply chain procedures.

Q: What is the significance of the asymmetrical configuration in the FDPC8016S?

A: The FDPC8016S is specified as a 2 N-Channel (Dual) Asymmetrical configuration, indicating the two channels have different electrical characteristics. This differs from the FDMS3600S specification. Circuit design must account for channel asymmetry if both channels are utilized.
