Engineering Selection Recommendations

Direct Electrical Equivalents (600 V, 8 A Rating):

RFV8TJ6SGC9 and RFVS8TJ6SGC9 from Rohm Semiconductor are direct electrical equivalents to the VS-ETL0806FP-M3. Both devices maintain the 600 V reverse voltage and 8 A average rectified current specifications. Both are ROHS3 compliant and rated for 150°C maximum junction temperature. RFV8TJ6SGC9 offers 2410 pcs inventory availability, while RFVS8TJ6SGC9 provides 2787 pcs. The primary difference is forward voltage specification: RFV8TJ6SGC9 at 2.8 V @ 8 A and RFVS8TJ6SGC9 at 3 V @ 8 A, both higher than the VS-ETL0806FP-M3 at 1.07 V @ 8 A.

Higher Current Rated Alternatives (600 V, ≥ 10 A):

RFNL10TJ6SGC9, RFNL15TJ6SGC9, RFNL20TJ6SGC9, RFV12TJ6SGC9, and RFV15TJ6SGC9 provide higher current ratings while maintaining 600 V reverse voltage. These parts are suitable for applications requiring current margin above 8 A. All are ROHS3 compliant with 150°C maximum junction temperature ratings.

Lower Voltage Alternative (400 V, 8 A):

DURF840 from Littelfuse Inc. is a 400 V rated device with 8 A current capacity. This part is suitable only for applications where the maximum reverse voltage requirement does not exceed 400 V. DURF840 features an isolated tab variant (ITO-220AC) and offers the highest inventory availability at 11827 pcs. Operating temperature maximum is 150°C.

Compliance and Certification:

All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the VS-ETL0806FP-M3. All parts are classified as Active product status.

Frequently Asked Questions (FAQ)

Q: Can DURF840 be used as a direct substitute for VS-ETL0806FP-M3?

A: DURF840 is not a direct substitute. While both devices are rated for 8 A average rectified current and feature TO-220-2 Full Pack packaging with isolated tab options, DURF840 is rated for 400 V maximum reverse voltage compared to the VS-ETL0806FP-M3 at 600 V. DURF840 is suitable only for applications where the circuit maximum reverse voltage does not exceed 400 V.

Q: What is the difference between RFV8TJ6SGC9 and RFVS8TJ6SGC9?

A: Both parts are 600 V, 8 A rated devices from Rohm Semiconductor in TO-220-2 Full Pack packaging. The primary difference is forward voltage specification: RFV8TJ6SGC9 is specified at 2.8 V @ 8 A with 45 ns reverse recovery time, while RFVS8TJ6SGC9 is specified at 3 V @ 8 A with 40 ns reverse recovery time. Both are ROHS3 compliant with 150°C maximum junction temperature.

Q: Why do some substitute parts have higher current ratings than 8 A?

A: Higher current rated devices (RFNL10TJ6SGC9, RFNL15TJ6SGC9, RFNL20TJ6SGC9, RFV12TJ6SGC9, RFV15TJ6SGC9) are listed as substitutes because they maintain the 600 V reverse voltage specification and exceed the 8 A minimum requirement. These parts are suitable for applications requiring current margin or where circuit redesign allows utilization of higher current capacity.

Q: Are all substitute parts available in the same package as VS-ETL0806FP-M3?

A: All substitute parts are available in TO-220-2 Full Pack or compatible TO-220ACFP packaging with isolated tab options. Package mechanical compatibility is maintained across all listed substitutes for through-hole mounting applications.

Q: What is the operating temperature range difference between VS-ETL0806FP-M3 and Rohm substitutes?

A: VS-ETL0806FP-M3 is rated for -65°C to 175°C junction temperature. Rohm Semiconductor substitutes (RFNL and RFV series) are rated for maximum 150°C junction temperature. This represents a 25°C reduction in maximum operating temperature for Rohm parts. Applications requiring operation above 150°C junction temperature must use the VS-ETL0806FP-M3 or equivalent Vishay devices.

Q: Can RFNL5TJ6SGC9 be used in place of VS-ETL0806FP-M3?

A: RFNL5TJ6SGC9 is not suitable as a direct substitute. While it maintains 600 V reverse voltage and TO-220-2 Full Pack packaging, it is rated for only 5 A average rectified current, which is below the 8 A requirement of the VS-ETL0806FP-M3. This part is suitable only for applications requiring 5 A or less.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the VS-ETL0806FP-M3. All parts are classified as Active product status. Moisture Sensitivity Level (MSL) varies by manufacturer and part number but does not affect substitution eligibility for standard through-hole applications.
