Substitute Part Grouping Explanation

Substitution of the RSFBL M2G is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100V minimum
Package / Case: DO-219AB (Surface Mount compatibility)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

Current - Average Rectified (Io): Equal to or greater than 500mA
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature Range: Minimum -55°C to 150°C junction temperature

The substitute parts ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I meet the primary substitution criteria. Differences in forward voltage, reverse recovery time, and maximum current ratings are secondary parameters that determine application suitability within the same electrical class.

Engineering Selection Recommendations

ES07B-GS08 (Vishay General Semiconductor - Diodes Division)

The ES07B-GS08 is a direct electrical equivalent to the RSFBL M2G with identical voltage and current ratings. Both components are rated for 100V DC reverse voltage and 500mA average rectified current. The ES07B-GS08 features improved reverse recovery time (25 ns versus 150 ns) and is qualified to AEC-Q101 automotive standard. This part is suitable for applications requiring automotive-grade reliability. All compliance requirements (ROHS3, REACH, MSL 1) are met.

ES07B-GS18 (Vishay General Semiconductor - Diodes Division)

The ES07B-GS18 provides higher current capacity at 1.2A average rectified current while maintaining the same 100V reverse voltage rating and DO-219AB package. This part is applicable when design margins require current headroom beyond the 500mA specification. Reverse recovery time is 25 ns. All compliance requirements are met. This part is not automotive qualified.

VS-2EFH01HM3/I (Vishay General Semiconductor - Diodes Division)

The VS-2EFH01HM3/I is a high-current variant rated for 2A average rectified current at 100V reverse voltage. This part features the fastest reverse recovery time (16 ns) and lowest reverse leakage current (2 µA) among the substitute options. The operating temperature range extends to -65°C to 175°C, providing wider thermal margins. This part is qualified to AEC-Q101 automotive standard and is part of the FRED Pt® series. All compliance requirements are met.

Frequently Asked Questions (FAQ)

Q: Can ES07B-GS08 be used as a direct replacement for RSFBL M2G?

A: Yes. Both parts share identical voltage (100V) and current (500mA) ratings, operate in the same DO-219AB package, and meet ROHS3 and MSL 1 requirements. The ES07B-GS08 features faster reverse recovery time (25 ns versus 150 ns), which is advantageous in switching applications.

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

A: The primary difference is current rating. ES07B-GS18 is rated for 1.2A average rectified current, while ES07B-GS08 is rated for 500mA. Both share the same 100V reverse voltage rating, DO-219AB package, and 25 ns reverse recovery time. ES07B-GS18 is suitable for applications requiring higher current capacity.

Q: Is VS-2EFH01HM3/I compatible with the RSFBL M2G footprint?

A: Yes. VS-2EFH01HM3/I uses the same DO-219AB package and Surface Mount configuration. However, this part is rated for 2A average rectified current, which exceeds the RSFBL M2G specification. It is suitable for applications requiring higher current handling or improved performance characteristics such as faster reverse recovery (16 ns) and lower reverse leakage (2 µA).

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (ES07B-GS08, ES07B-GS18, and VS-2EFH01HM3/I) are ROHS3 compliant and REACH unaffected, matching the compliance status of the RSFBL M2G.

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

A: Reverse recovery time (trr) affects switching speed and efficiency in high-frequency applications. The RSFBL M2G has 150 ns trr, while ES07B-GS08 and ES07B-GS18 have 25 ns, and VS-2EFH01HM3/I has 16 ns. Faster recovery times reduce switching losses and are beneficial in power conversion circuits operating at higher frequencies.

Q: Can I use a higher-current rated part in place of the RSFBL M2G?

A: Yes. Parts with higher current ratings (ES07B-GS18 at 1.2A or VS-2EFH01HM3/I at 2A) are electrically compatible with the RSFBL M2G in the same package. Higher-rated parts provide design margin and improved performance characteristics. Circuit design must account for any differences in forward voltage and reverse leakage characteristics.

Q: What is the operating temperature range for each part?

A: RSFBL M2G, ES07B-GS08, and ES07B-GS18 operate from -55°C to 150°C junction temperature. VS-2EFH01HM3/I extends this range to -65°C to 175°C, providing wider thermal operating margins for extreme environment applications.

Q: Are automotive qualifications available for all substitutes?

A: ES07B-GS08 and VS-2EFH01HM3/I are both qualified to AEC-Q101 automotive standard. ES07B-GS18 does not carry automotive qualification. Selection depends on application requirements.
