Parameter Comparison

Engineering Selection Recommendations

The VF40100C-E3/4W qualifies as a direct substitute for the DSTF40100C based on complete electrical and mechanical parameter equivalence. Both components maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance across manufacturing and end-use applications.

The Vishay VF40100C-E3/4W demonstrates a marginal improvement in forward voltage specification (730 mV versus 750 mV at 20A), which represents enhanced efficiency characteristics while maintaining full compatibility with circuit designs specified for the Littelfuse DSTF40100C.

Inventory availability differs between manufacturers: DSTF40100C maintains 933 pieces in stock, while VF40100C-E3/4W provides 2243 pieces, supporting extended procurement windows and supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can the VF40100C-E3/4W replace the DSTF40100C in existing circuit designs?

A: Yes. The VF40100C-E3/4W is electrically and mechanically equivalent to the DSTF40100C. Both components share identical reverse voltage (100V), average rectified current (20A per diode), package configuration (TO-220-3 Full Pack, Isolated Tab), and compliance certifications (RoHS3, REACH Unaffected). No circuit redesign is required.

Q: What is the significance of the forward voltage difference between these parts?

A: The VF40100C-E3/4W specifies 730 mV forward voltage at 20A, compared to 750 mV for the DSTF40100C. This 20 mV difference represents improved efficiency in the Vishay device and is within acceptable substitution parameters. Both values fall within the operational envelope of applications designed for 100V, 20A Schottky diode arrays.

Q: Are the package dimensions identical between DSTF40100C and VF40100C-E3/4W?

A: Yes. Both components use the TO-220-3 Full Pack with isolated tab configuration (ITO-220AB supplier device package). Pin configuration, mounting hole spacing, and thermal interface characteristics are identical, enabling direct board-level substitution without mechanical redesign.

Q: What compliance certifications apply to both substitute parts?

A: Both the DSTF40100C and VF40100C-E3/4W maintain RoHS3 compliance and REACH Unaffected status. Moisture sensitivity level is rated at MSL 1 (Unlimited) for both components, indicating no moisture-related handling restrictions during storage or assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The DSTF40100C specifies operating junction temperature range of -55°C to 150°C. The VF40100C-E3/4W does not provide explicit operating temperature data in the supplied parameters. For applications requiring confirmed temperature performance specifications, refer to manufacturer datasheets for the Vishay component.

Q: What is the reverse leakage current specification for both parts?

A: Both the DSTF40100C and VF40100C-E3/4W specify reverse leakage current of 1 mA at 100V reverse voltage. This parameter is identical across both components and represents the maximum leakage current under rated reverse bias conditions.
