Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8EWS16STRL are determined by strict equivalence across the following critical parameters:

• Voltage Rating: All substitutes maintain 1600 V DC reverse voltage (Vr) maximum
• Current Rating: All substitutes maintain 8 A average rectified current (Io)
• Forward Voltage: All substitutes maintain 1.1 V maximum forward voltage at 8 A
• Reverse Leakage: All substitutes maintain 50 µA maximum reverse leakage at 1600 V
• Recovery Speed: All substitutes maintain standard recovery characteristics >500ns at >200mA
• Package: All substitutes use identical TO-252-3 DPAK (2 Leads + Tab) surface mount package
• Operating Temperature Range: All substitutes maintain -40°C to 150°C junction temperature range
• Moisture Sensitivity: All substitutes maintain MSL 1 (Unlimited)

The three substitute parts listed are all manufactured by Vishay General Semiconductor - Diodes Division and share the same base product number (8EWS16), ensuring functional and mechanical compatibility with the original 8EWS16STRL.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (VS-8EWS16SLHM3, VS-8EWS16STR-M3, and VS-8EWS16STRR-M3) are electrically and mechanically equivalent to the obsolete 8EWS16STRL and are suitable for direct replacement based on parametric equivalence.

Product Status Consideration: The original 8EWS16STRL is obsolete. All three substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain continuity.

Compliance Advantage: All substitute parts are ROHS3 compliant, whereas the original 8EWS16STRL is RoHS non-compliant. This compliance improvement supports modern regulatory requirements and environmental standards.

Packaging Format: The original part is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and provides improved handling and traceability.

Automotive Grade Option: VS-8EWS16SLHM3 is qualified to AEC-Q101 automotive standards and carries an automotive grade designation. This part is suitable for applications requiring automotive-level reliability and qualification.

Series Designation: VS-8EWS16STRR-M3 is part of the FRED Pt® series. This designation indicates advanced rectifier technology within the Vishay product line while maintaining full parametric equivalence.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts be used as direct replacements for the 8EWS16STRL?

A: Yes. All three substitute parts (VS-8EWS16SLHM3, VS-8EWS16STR-M3, and VS-8EWS16STRR-M3) are parametrically equivalent to the 8EWS16STRL across all critical electrical and mechanical specifications, including voltage rating, current rating, forward voltage, reverse leakage, recovery speed, package type, and operating temperature range. They are suitable for direct replacement in existing designs.

Q: What is the difference between the three substitute parts?

A: The three substitute parts share identical electrical and mechanical specifications. The primary differences are: VS-8EWS16SLHM3 includes automotive grade designation and AEC-Q101 qualification; VS-8EWS16STR-M3 is a standard-grade variant; VS-8EWS16STRR-M3 is designated as part of the FRED Pt® series. All are ROHS3 compliant and supplied in Tape & Reel packaging.

Q: Is the package identical across all parts?

A: Yes. All parts, including the original 8EWS16STRL and all three substitutes, use the TO-252-3 DPAK (2 Leads + Tab) surface mount package with SC-63 designation. Pin configuration and footprint are identical, allowing direct PCB compatibility without layout modifications.

Q: Why is the original 8EWS16STRL obsolete?

A: The 8EWS16STRL has been discontinued by the manufacturer. The substitute parts represent the current active product offerings from Vishay General Semiconductor - Diodes Division that maintain full parametric equivalence while offering improved compliance status (ROHS3) and modern packaging formats (Tape & Reel).

Q: Are there any temperature or environmental differences between the parts?

A: No. All parts maintain identical operating temperature range (-40°C to 150°C junction temperature) and moisture sensitivity level (MSL 1, Unlimited). Environmental performance characteristics are equivalent across all parts.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For automotive applications requiring qualification and reliability standards, VS-8EWS16SLHM3 (AEC-Q101 qualified) is appropriate. For general-purpose applications, VS-8EWS16STR-M3 or VS-8EWS16STRR-M3 are suitable. All three parts are active products with current availability and ROHS3 compliance.

Q: Are the electrical characteristics identical between all parts?

A: Yes. All parts maintain identical voltage rating (1600 V), current rating (8 A), forward voltage (1.1 V @ 8 A), reverse leakage (50 µA @ 1600 V), and recovery speed (Standard Recovery >500ns, >200mA). Electrical performance is equivalent across all parts.
