Substitute Part Grouping Explanation

Substitute parts for the RSFBL RVG are grouped based on the following substitution criteria:

Manufacturer Recommended Substitute (Higher Voltage Rating): The RS1DLW RVG is a manufacturer-recommended substitute that exceeds the voltage specification (200 V vs. 100 V) while maintaining the fast recovery speed classification and surface mount technology. This part is suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

Similar Substitutes (Equivalent Voltage, Same Package): The ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I are classified as similar substitutes because they maintain the 100 V DC reverse voltage rating and DO-219AB package compatibility with the RSFBL RVG. These parts differ in current rating capacity and reverse recovery time characteristics:

ES07B-GS08: Matches 500 mA current rating with improved reverse recovery time (25 ns vs. 150 ns)
ES07B-GS18: Increases current capacity to 1.2 A with improved reverse recovery time (25 ns)
VS-2EFH01HM3/I: Increases current capacity to 2 A with superior reverse recovery time (16 ns) and lower reverse leakage current (2 µA vs. 5 µA)

All substitute parts maintain Fast Recovery speed classification, ROHS3 compliance, and surface mount technology.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): The ES07B-GS08 provides direct electrical substitution with identical 100 V and 500 mA ratings. This part maintains DO-219AB package compatibility and offers improved reverse recovery time (25 ns), resulting in lower switching losses. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating.

For Higher Voltage Applications: The RS1DLW RVG is the manufacturer-recommended substitute when circuit design requires 200 V reverse voltage rating. This part maintains Fast Recovery speed classification and ROHS3 compliance. Package change from Sub SMA to SOD-123W requires PCB layout modification.

For Increased Current Capacity: The ES07B-GS18 and VS-2EFH01HM3/I provide higher current ratings (1.2 A and 2 A respectively) while maintaining 100 V voltage rating and DO-219AB package compatibility. Both parts are ROHS3 compliant. The VS-2EFH01HM3/I offers superior performance with 16 ns reverse recovery time and 2 µA reverse leakage current, with extended operating temperature range (-65 to 175°C) and AEC-Q101 automotive qualification.

For Automotive Applications: The ES07B-GS08 and VS-2EFH01HM3/I carry AEC-Q101 qualification, suitable for automotive-grade circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the RS1DLW RVG be used as a direct replacement for the RSFBL RVG?

A: The RS1DLW RVG is electrically compatible for applications operating at or below 100 V. The higher 200 V rating provides additional voltage margin. However, the package changes from Sub SMA (DO-219AB) to SOD-123W, requiring PCB layout modification. Both parts maintain Fast Recovery speed classification and ROHS3 compliance.

Q: What is the difference between the ES07B-GS08 and ES07B-GS18?

A: Both parts use the DO-219AB package and maintain 100 V voltage rating. The ES07B-GS18 provides higher current capacity (1.2 A vs. 500 mA). Both offer identical 25 ns reverse recovery time and ROHS3 compliance. Selection depends on circuit current requirements.

Q: Is the VS-2EFH01HM3/I suitable for high-temperature applications?

A: The VS-2EFH01HM3/I operates across -65 to 175°C junction temperature range, compared to the RSFBL RVG range of -55 to 150°C. This extended range accommodates higher ambient temperature environments. The part carries AEC-Q101 automotive qualification and ROHS3 compliance.

Q: Do all substitute parts maintain the same package footprint?

A: The ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I use DO-219AB (SMF) package, compatible with the RSFBL RVG DO-219AB (Sub SMA) footprint. The RS1DLW RVG uses SOD-123W package, requiring PCB layout modification.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and power dissipation. The RSFBL RVG has 150 ns trr, while ES07B-GS08 and ES07B-GS18 have 25 ns, and VS-2EFH01HM3/I has 16 ns. Lower trr values reduce switching losses and improve efficiency in high-frequency applications.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts (RS1DLW RVG, ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
