Substitute Part Grouping Explanation

Substitution of the VS-8EWF02SPBF with the VS-8EWF02S-M3 is based on strict equivalence of the following critical parameters:

Voltage Rating: Both parts rated at 200 V DC reverse voltage maximum
Current Rating: Both parts rated at 8 A average rectified current
Forward Voltage Drop: Both parts specify 1.2 V maximum at 8 A
Reverse Leakage Current: Both parts specify 100 µA at 200 V
Package Configuration: Both use TO-252-3 DPAK (2 Leads + Tab) surface mount package
Mounting Type: Both are surface mount components
Temperature Range: Both support -40°C to 150°C junction operating temperature (VS-8EWF02S-M3 has narrower lower limit)
Compliance: Both are ROHS3 compliant with REACH unaffected status

The VS-8EWF02S-M3 differs in product status (active versus obsolete) and recovery speed classification, with the substitute offering fast recovery characteristics (≤500 ns, >200 mA) compared to the standard recovery (>500 ns, >200 mA) of the main part.

Engineering Selection Recommendations

The VS-8EWF02S-M3 is a direct functional equivalent for the obsolete VS-8EWF02SPBF based on matching voltage, current, and package specifications. Selection of the substitute part is supported by:

Active Product Status: VS-8EWF02S-M3 is actively manufactured and stocked (1888 pcs available), ensuring supply continuity for the obsolete VS-8EWF02SPBF
Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and safety requirements
Electrical Equivalence: Identical voltage ratings (200 V), current ratings (8 A), forward voltage drop (1.2 V @ 8 A), and reverse leakage current (100 µA @ 200 V) ensure functional interchangeability in circuit applications
Package Compatibility: Identical TO-252-3 DPAK surface mount package enables direct PCB layout compatibility without redesign

Operational Considerations: The VS-8EWF02S-M3 exhibits faster recovery characteristics (≤500 ns versus >500 ns) and specifies a reverse recovery time of 55 ns. Applications requiring operation below -40°C junction temperature must retain the original VS-8EWF02SPBF or identify alternative parts with extended low-temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can VS-8EWF02S-M3 be used as a direct replacement for VS-8EWF02SPBF in existing designs?

A: Yes, for applications operating within the -40°C to 150°C junction temperature range. Both parts share identical voltage (200 V), current (8 A), forward voltage drop (1.2 V @ 8 A), and package specifications (TO-252-3 DPAK). The substitute part's faster recovery time (≤500 ns) is compatible with standard recovery circuit designs.

Q: What is the difference in recovery speed between these parts?

A: The VS-8EWF02SPBF is classified as standard recovery (>500 ns, >200 mA), while the VS-8EWF02S-M3 is fast recovery (≤500 ns, >200 mA) with a specified reverse recovery time of 55 ns. Fast recovery diodes exhibit lower switching losses and are suitable for higher-frequency applications.

Q: Are there temperature range limitations when substituting?

A: The VS-8EWF02SPBF operates from -55°C to 150°C junction temperature, while the VS-8EWF02S-M3 operates from -40°C to 150°C. Applications requiring operation below -40°C must use the original part or identify alternatives with extended low-temperature specifications.

Q: Do both parts use the same package?

A: Yes. Both the VS-8EWF02SPBF and VS-8EWF02S-M3 use the TO-252-3 DPAK (2 Leads + Tab) surface mount package, enabling direct PCB compatibility without layout modifications.

Q: What is the availability status of each part?

A: The VS-8EWF02SPBF is obsolete with 2000 pcs in stock. The VS-8EWF02S-M3 is active with 1888 pcs in stock, providing ongoing supply for new production and design continuity.

Q: Are both parts RoHS compliant?

A: Yes. Both the VS-8EWF02SPBF and VS-8EWF02S-M3 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
