RSFDL M2G Equivalent & Substitute Parts

Part Overview

The RSFDL M2G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 500 mA average rectified current in a Sub SMA surface mount package (DO-219AB). This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the RSFDL M2G reaches end-of-life status, when specific packaging formats are required for manufacturing processes, or when alternative manufacturers' components offer equivalent electrical performance with improved availability or cost structure.

Substitute Part Grouping Explanation

Substitute parts for the RSFDL M2G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 200 V reverse voltage, 500 mA average rectified current, 1.3 V forward voltage at 500 mA, 150 ns reverse recovery time, and DO-219AB package format. These parts differ only in packaging format (Tape & Reel versus Cut Tape) or product status designation. Parametric equivalents include RSFDL and RSFDL R3G.

Similar Parts share the same 200 V reverse voltage rating and DO-219AB package but differ in one or more of the following parameters: average rectified current rating, forward voltage characteristics, reverse recovery time, reverse leakage current, or operating temperature range. Similar parts include RS07D-GS08, VS-1EFH02-M3/I, and VS-2EFH02HM3/I. These components are suitable for applications where the specified parameter differences do not conflict with circuit requirements.

The critical parameters determining substitution eligibility are: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Package / Case, and Mounting Type.

Engineering Selection Recommendations

For Parametric Equivalents (RSFDL and RSFDL R3G):

RSFDL R3G is the preferred parametric equivalent for new designs. This part maintains identical electrical specifications to the RSFDL M2G across all critical parameters and carries Active product status. RSFDL R3G is supplied in Cut Tape (CT) packaging format with 725 units in stock inventory.

RSFDL is a parametric equivalent with identical electrical specifications but carries Not For New Designs product status. This part is supplied in Tape & Reel (TR) packaging format with 13,300 units in stock inventory. RSFDL is suitable for legacy system maintenance and repair applications where design changes are not feasible.

For Similar Parts (RS07D-GS08, VS-1EFH02-M3/I, VS-2EFH02HM3/I):

RS07D-GS08 (Vishay General Semiconductor - Diodes Division) maintains the 200 V reverse voltage and 500 mA current rating with identical package format. This part carries Active product status and AEC-Q101 automotive qualification. RS07D-GS08 exhibits lower forward voltage (1.15 V @ 700 mA) and higher reverse leakage current (10 µA @ 200 V) compared to the RSFDL M2G. This part is suitable for applications where automotive qualification is required and the specified parameter differences are acceptable.

VS-1EFH02-M3/I (Vishay General Semiconductor - Diodes Division, FRED Pt® series) is rated for 1 A average rectified current with significantly improved reverse recovery time (16 ns versus 150 ns) and lower reverse leakage current (2 µA @ 200 V). This part carries Active product status and extended operating temperature range (-65 to 175°C). VS-1EFH02-M3/I is suitable for applications requiring higher current capacity or improved switching performance.

VS-2EFH02HM3/I (Vishay General Semiconductor - Diodes Division, FRED Pt® series) is rated for 2 A average rectified current with improved reverse recovery time (25 ns) and lower reverse leakage current (2 µA @ 200 V).

Frequently Asked Questions (FAQ)

Q: Can RSFDL R3G be used as a direct replacement for RSFDL M2G?

A: Yes. RSFDL R3G is a parametric equivalent with identical electrical specifications: 200 V reverse voltage, 500 mA average rectified current, 1.3 V forward voltage at 500 mA, 150 ns reverse recovery time, and DO-219AB package format. The only difference is packaging format (Cut Tape versus the original packaging). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between RSFDL and RSFDL R3G?

A: RSFDL and RSFDL R3G are parametric equivalents with identical electrical specifications. The primary differences are: RSFDL carries Not For New Designs product status while RSFDL R3G is Active; RSFDL is supplied in Tape & Reel (TR) format while RSFDL R3G is supplied in Cut Tape (CT) format; RSFDL has higher inventory availability (13,300 units) compared to RSFDL R3G (725 units).

Q: Can RS07D-GS08 replace RSFDL M2G in all applications?

A: RS07D-GS08 shares the same 200 V reverse voltage, 500 mA current rating, and DO-219AB package format. However, RS07D-GS08 exhibits different forward voltage characteristics (1.15 V @ 700 mA versus 1.3 V @ 500 mA) and higher reverse leakage current (10 µA @ 200 V versus 5 µA @ 200 V). Substitution is acceptable only when these parameter differences do not conflict with circuit requirements. RS07D-GS08 carries AEC-Q101 automotive qualification, making it suitable for automotive applications.

Q: When should VS-1EFH02-M3/I or VS-2EFH02HM3/I be selected instead of RSFDL M2G?

A: VS-1EFH02-M3/I and VS-2EFH02HM3/I are similar parts with higher current ratings (1 A and 2 A respectively) and significantly improved reverse recovery time (16 ns and 25 ns respectively). These parts are selected when applications require higher current capacity or improved switching performance. VS-2EFH02HM3/I additionally carries AEC-Q101 automotive qualification. Both parts support extended operating temperature range (-65 to 175°C versus -55 to 150°C).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (RSFDL, RSFDL R3G, RS07D-GS08, VS-1EFH02-M3/I, and VS-2EFH02HM3/I) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What is the difference in reverse recovery time between RSFDL M2G and the Vishay FRED Pt® series parts?

A: RSFDL M2G has a reverse recovery time of 150 ns. VS-1EFH02-M3/I has 16 ns reverse recovery time, and VS-2EFH02HM3/I has 25 ns reverse recovery time. The Vishay FRED Pt® series parts exhibit significantly faster switching characteristics, which reduces switching losses and improves efficiency in high-frequency applications.

Q: Can RSFDL M2G be used in automotive applications?

A: RSFDL M2G does not carry AEC-Q101 automotive qualification. For automotive applications requiring qualified components, RS07D-GS08 or VS-2EFH02HM3/I are suitable alternatives, both of which carry AEC-Q101 qualification.
