Engineering Selection Recommendations

VS-8EWS08STR-M3 is the primary substitute for the 8EWS08STRL. This part maintains full electrical and mechanical equivalence while offering active product status and ROHS3 compliance. The part is available in Tape & Reel packaging and has higher inventory availability (15,400 units in stock).

VS-8EWS08STRR-M3 is an alternative substitute with identical electrical and mechanical specifications. This part also maintains active product status and ROHS3 compliance. Inventory availability is lower (700 units in stock) compared to VS-8EWS08STR-M3.

Both substitute parts eliminate the compliance and obsolescence concerns associated with the original 8EWS08STRL while maintaining full functional equivalence for 800 V, 8 A rectifier applications in TO-252AA (DPAK) surface mount configurations.

Frequently Asked Questions (FAQ)

Q: Can VS-8EWS08STR-M3 and VS-8EWS08STRR-M3 be used interchangeably with 8EWS08STRL?

A: Yes. Both substitute parts meet all electrical parameters (800 V reverse voltage, 8 A average rectified current, 1.1 V forward voltage at 8 A, 50 µA reverse leakage at 800 V, and standard recovery speed) and mechanical specifications (TO-252-3 DPAK package, surface mount, -55°C to 150°C operating range) required for direct substitution.

Q: What is the difference between VS-8EWS08STR-M3 and VS-8EWS08STRR-M3?

A: Both parts are electrically and mechanically identical. The primary difference is packaging format (both are Tape & Reel) and inventory availability. VS-8EWS08STR-M3 has 15,400 units in stock, while VS-8EWS08STRR-M3 has 700 units in stock.

Q: Why is the 8EWS08STRL classified as obsolete?

A: The 8EWS08STRL is listed as obsolete by the manufacturer. The active equivalent parts VS-8EWS08STR-M3 and VS-8EWS08STRR-M3 provide continued design support and procurement options.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both VS-8EWS08STR-M3 and VS-8EWS08STRR-M3 are ROHS3 compliant, whereas the original 8EWS08STRL is RoHS non-compliant.

Q: Does the packaging format affect electrical performance?

A: No. The packaging format (Tape & Reel for substitutes versus bulk for the original) does not affect electrical performance. Both formats contain the same TO-252AA (DPAK) component.

Q: What are the key electrical parameters that define substitution for this diode?

A: The critical parameters are: 800 V DC reverse voltage rating, 8 A average rectified current, 1.1 V maximum forward voltage at 8 A, 50 µA reverse leakage current at 800 V, and standard recovery speed greater than 500 ns at currents above 200 mA.
