8EWF02STR Equivalent & Substitute Parts

Part Overview

The 8EWF02STR is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 8 A average rectified current. The device is packaged in a TO-252-3 (DPAK) surface mount configuration with a maximum forward voltage of 1.2 V at 8 A and fast recovery characteristics with a reverse recovery time of 140 ns.

The 8EWF02STR is classified as obsolete. Locating active production alternatives is necessary for new designs, ongoing production support, and long-term component availability assurance. Substitute parts maintain electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8EWF02STR are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 8 A
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 200 V
• Operating Temperature - Junction: -40°C ~ 150°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Supplier Device Package: TO-252AA (DPAK)

All substitute parts listed maintain identical electrical ratings and mechanical form factors. Variations in reverse recovery time (trr) and packaging format (Tape & Reel versus bulk) do not affect functional substitution within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (VS-8EWF02STR-M3, VS-8EWF02STRL-M3, and VS-8EWF02STRR-M3) are direct electrical and mechanical equivalents to the 8EWF02STR. Selection among these active alternatives is based on product status and compliance requirements:

VS-8EWF02STR-M3 is recommended for applications requiring the shortest reverse recovery time (55 ns) combined with active product status and ROHS3 compliance. This part offers the highest inventory availability (30,300 pcs) and represents the optimal choice for new designs and production continuity.

VS-8EWF02STRL-M3 maintains active product status and ROHS3 compliance with a reverse recovery time of 200 ns, suitable for applications where recovery speed is less critical. This variant provides an alternative with moderate inventory levels (1,041 pcs).

VS-8EWF02STRR-M3 provides active product status and ROHS3 compliance with a reverse recovery time of 55 ns, matching the performance of VS-8EWF02STR-M3. Inventory availability is 744 pcs.

All substitute parts transition from the obsolete, RoHS non-compliant 8EWF02STR to active, ROHS3-compliant alternatives while maintaining identical electrical ratings and mechanical packaging.

Frequently Asked Questions (FAQ)

Q: Can VS-8EWF02STR-M3, VS-8EWF02STRL-M3, and VS-8EWF02STRR-M3 be used interchangeably with 8EWF02STR?

A: Yes. All three substitute parts maintain identical voltage ratings (200 V), current ratings (8 A), forward voltage characteristics (1.2 V @ 8 A), and mechanical packaging (TO-252-3 DPAK). Differences in reverse recovery time do not prevent functional substitution within the specified fast recovery classification.

Q: What is the primary reason to transition from 8EWF02STR to a substitute part?

A: The 8EWF02STR is classified as obsolete and is RoHS non-compliant. All substitute parts are active products with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and ongoing production.

Q: Are there differences in reverse recovery time among the substitute parts?

A: Yes. VS-8EWF02STR-M3 and VS-8EWF02STRR-M3 both feature a reverse recovery time of 55 ns, while VS-8EWF02STRL-M3 has a reverse recovery time of 200 ns. Both values remain within the fast recovery classification (≤ 500 ns, > 200 mA). Selection depends on application-specific switching speed requirements.

Q: What is the difference between bulk and Tape & Reel packaging?

A: The original 8EWF02STR is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Tape & Reel packaging does not affect electrical performance or mechanical compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (VS-8EWF02STR-M3, VS-8EWF02STRL-M3, and VS-8EWF02STRR-M3) are ROHS3 compliant, whereas the original 8EWF02STR is RoHS non-compliant.

Q: Which substitute part has the highest inventory availability?

A: VS-8EWF02STR-M3 has the highest inventory availability with 30,300 pcs in stock, followed by VS-8EWF02STRR-M3 (744 pcs) and VS-8EWF02STRL-M3 (1,041 pcs).

Q: Do the substitute parts operate within the same temperature range as the original part?

A: Yes. All substitute parts maintain the same operating temperature range of -40°C to 150°C junction temperature as the 8EWF02STR.
