Engineering Selection Recommendations

VS-ETH0806-M3 (Vishay General Semiconductor - FRED Pt® Series)

This substitute provides enhanced electrical performance with 600 V reverse voltage rating and 8 A current capacity. The part is active in production status with extended operating temperature range (-65°C to 175°C). Reverse recovery time of 21 ns is superior to the original specification. REACH Unaffected status and ROHS3 compliance ensure regulatory alignment. This part is suitable for applications requiring higher voltage or current margins.

BYC5-600,127 (WeEn Semiconductors)

This substitute maintains the original 500 V voltage and 5 A current ratings, providing direct electrical equivalence. The part is active in production with ROHS3 compliance. However, forward voltage is elevated at 2.9 V compared to the original 1.75 V, and reverse recovery time extends to 50 ns. REACH Affected status requires verification of regulatory requirements in target markets. This part is suitable for applications where voltage and current specifications are critical constraints.

SFA807G C0G (Taiwan Semiconductor Corporation)

This substitute provides 500 V reverse voltage with increased 8 A current capacity. The part is active in production with operating temperature range matching the original (-55°C to 150°C). Forward voltage of 1.7 V is comparable to the original specification. Reverse recovery time of 35 ns remains within fast recovery classification. REACH Unaffected status and ROHS3 compliance are confirmed. This part is suitable for applications requiring current capacity upgrade while maintaining thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the VS-ETH0806-M3 be used as a direct replacement for the UGE5HT-E3/45?

A: Yes. The VS-ETH0806-M3 meets all minimum electrical requirements with enhanced ratings. The 600 V reverse voltage and 8 A current capacity exceed the original 500 V and 5 A specifications. Both parts use identical TO-220-2 package configuration and through-hole mounting. The substitute is suitable for circuits designed for the original part.

Q: What is the primary difference between the BYC5-600,127 and other substitutes?

A: The BYC5-600,127 maintains exact voltage and current ratings (500 V, 5 A) matching the original UGE5HT-E3/45. However, forward voltage is significantly higher at 2.9 V versus 1.75 V, resulting in increased power dissipation. Reverse recovery time extends to 50 ns. This part is selected when voltage and current specifications are critical design constraints.

Q: Are all substitute parts compatible with the original TO-220AC package footprint?

A: Yes. All substitute parts use TO-220-2 package configuration with through-hole mounting. Physical footprint and pin configuration are identical to the original UGE5HT-E3/45, enabling direct PCB compatibility without layout modifications.

Q: What is the significance of REACH Affected status for the BYC5-600,127?

A: REACH Affected status indicates the part may contain substances of concern under European chemical regulations. Applications subject to REACH requirements must verify compliance with specific market regulations. The alternative substitutes (VS-ETH0806-M3 and SFA807G C0G) carry REACH Unaffected status, eliminating this regulatory consideration.

Q: Which substitute provides the lowest forward voltage drop?

A: The SFA807G C0G provides forward voltage of 1.7 V at 8 A, which is the lowest among all substitutes and comparable to the original 1.75 V at 5 A. This characteristic reduces power dissipation in applications operating at rated current levels.

Q: Can the SFA807G C0G handle higher current than the original part?

A: Yes. The SFA807G C0G is rated for 8 A average rectified current compared to the original 5 A rating. This increased capacity provides design margin for applications with variable or peak current demands within the 8 A limit.

Q: What is the operating temperature range difference between substitutes?

A: The VS-ETH0806-M3 extends to -65°C minimum and 175°C maximum, providing the widest operating range. The BYC5-600,127 specifies 150°C maximum without a minimum temperature rating. The SFA807G C0G matches the original range of -55°C to 150°C. Selection depends on thermal environment requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts carry ROHS3 Compliant status, matching the original UGE5HT-E3/45. This ensures compatibility with RoHS-regulated applications and procurement requirements.
