Engineering Selection Recommendations

HS1JL RVG is the primary substitute for HS1JL RUG. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications, including 600 V reverse voltage, 1 A average rectified current, 1.7 V forward voltage at 1 A, and 75 ns reverse recovery time. Both maintain Active product status and ROHS3 compliance. The HS1JL RVG is available in Cut Tape (CT) packaging with 1030 pieces in stock.

ES1JL is a parametric equivalent manufactured by Taiwan Semiconductor Corporation with matching voltage and current ratings. This part exhibits improved reverse recovery time (35 ns versus 75 ns) and reduced capacitance (8pF versus 15pF). However, ES1JL carries Not For New Designs product status, limiting its application to legacy system support or inventory replacement scenarios. ES1JL is available in Cut Tape (CT) and Digi-Reel® packaging with 84500 pieces in stock.

VS-1EFU06HM3/I (Vishay General Semiconductor - Diodes Division) provides functional equivalence at the 1 A current rating with superior electrical characteristics: 1.2 V forward voltage at 1 A, 32 ns reverse recovery time, and 3 µA reverse leakage current. This part qualifies as Automotive grade with AEC-Q101 certification and extends operating temperature to -55°C ~ 175°C. VS-1EFU06HM3/I is suitable for applications requiring enhanced performance and automotive-grade reliability. Inventory: 36329 pieces.

VS-2EFU06HM3/I (Vishay General Semiconductor - Diodes Division) provides a 2 A current rating variant with 600 V reverse voltage in the same DO-219AB package. This part is applicable where circuit design permits higher current capacity. It maintains Automotive grade qualification with AEC-Q101 certification and -55°C ~ 175°C operating temperature range. Inventory: 10200 pieces.

Frequently Asked Questions (FAQ)

Q: Can ES1JL be used as a direct replacement for HS1JL RUG?

A: ES1JL meets the primary electrical and mechanical substitution criteria: 600 V reverse voltage, 1 A average rectified current, DO-219AB package, and Surface Mount configuration. However, ES1JL carries Not For New Designs product status. Use ES1JL only for legacy system maintenance or inventory replacement where the original part is unavailable.

Q: What is the difference between HS1JL RUG and HS1JL RVG?

A: HS1JL RUG and HS1JL RVG are electrically identical with matching 600 V reverse voltage, 1 A current rating, 1.7 V forward voltage, and 75 ns reverse recovery time. The primary difference is packaging: HS1JL RUG uses standard packaging while HS1JL RVG is supplied in Cut Tape (CT) format. Both maintain Active product status and ROHS3 compliance.

Q: Can VS-1EFU06HM3/I replace HS1JL RUG in all applications?

A: VS-1EFU06HM3/I is electrically compatible at the 1 A current rating with superior performance characteristics: lower forward voltage (1.2 V versus 1.7 V), faster reverse recovery (32 ns versus 75 ns), and lower reverse leakage (3 µA versus 5 µA). Both parts use the DO-219AB package and Surface Mount configuration. VS-1EFU06HM3/I includes Automotive grade qualification and AEC-Q101 certification, making it suitable for applications requiring enhanced reliability.

Q: Why would VS-2EFU06HM3/I be selected over VS-1EFU06HM3/I?

A: VS-2EFU06HM3/I provides 2 A average rectified current compared to 1 A in VS-1EFU06HM3/I. Selection depends on circuit current requirements. If the application circuit design permits or requires higher current capacity, VS-2EFU06HM3/I offers additional margin. Both parts maintain identical 600 V reverse voltage, DO-219AB package, Automotive grade, and AEC-Q101 qualification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. HS1JL RUG, ES1JL, HS1JL RVG, VS-1EFU06HM3/I, and VS-2EFU06HM3/I are all ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the operating temperature range difference between Taiwan Semiconductor and Vishay parts?

A: Taiwan Semiconductor Corporation parts (HS1JL RUG, ES1JL, HS1JL RVG) operate from -55°C to 150°C junction temperature. Vishay General Semiconductor parts (VS-1EFU06HM3/I, VS-2EFU06HM3/I) extend to -55°C to 175°C. The 25°C extended upper temperature range in Vishay parts provides additional thermal margin for high-temperature applications.

Q: Is packaging format (Cut Tape, Digi-Reel, Tape & Reel) a substitution factor?

A: Packaging format affects supply chain logistics and assembly processes but does not alter electrical or mechanical compatibility. All substitute parts use the same DO-219AB package and Surface Mount configuration. Packaging format selection depends on manufacturing requirements and inventory management practices.
