RSFDL RHG Equivalent & Substitute Parts

Part Overview

The RSFDL RHG 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). The device features fast recovery characteristics with a reverse recovery time of 150 ns and operates across a junction temperature range of -55°C to 150°C. This part is currently Active and ROHS3 Compliant.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design requirements necessitate different electrical performance characteristics within compatible voltage and current ratings.

Substitute Part Grouping Explanation

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

Parametric Equivalents share identical electrical specifications and package type (DO-219AB Sub SMA), differing only in packaging format (Tape & Reel versus Cut Tape) or product status designation. These parts maintain the same voltage rating (200 V), current rating (500 mA), forward voltage (1.3 V @ 500 mA), and reverse recovery time (150 ns).

Similar Parts maintain the same reverse voltage rating (200 V) and package type (DO-219AB) but differ in one or more of the following parameters: average rectified current rating, forward voltage characteristics, reverse recovery time, or reverse leakage current. These parts are suitable for applications where the primary part is unavailable and the application can accommodate the modified electrical performance.

The critical parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 200 V (required match for parametric equivalents)
Package / Case: DO-219AB (required match for all substitutes)
Mounting Type: Surface Mount (required match for all substitutes)
Current - Average Rectified (Io): 500 mA minimum (parametric equivalents); higher ratings acceptable for similar parts
Reverse Recovery Time (trr): 150 ns (parametric equivalents); lower values acceptable for similar parts

Engineering Selection Recommendations

Parametric Equivalent Selection (RSFDL, RSFDL R3G)

The RSFDL and RSFDL R3G parts are direct parametric equivalents to the RSFDL RHG, maintaining identical electrical specifications across all critical parameters. Both parts are ROHS3 Compliant and carry Moisture Sensitivity Level 1 (Unlimited). The RSFDL R3G is designated as Active product status and is available in Cut Tape packaging format. The RSFDL is designated as Not For New Designs but remains available in Tape & Reel format with higher inventory levels (13,300 pieces). Selection between these equivalents should be based on packaging format requirements and product lifecycle considerations for new design implementations.

Similar Part Selection (RS07D-GS08, VS-1EFH02-M3/I, VS-2EFH02HM3/I)

The RS07D-GS08 maintains the 200 V reverse voltage rating and 500 mA current rating with identical reverse recovery time (150 ns). This part is manufactured by Vishay General Semiconductor - Diodes Division and carries AEC-Q101 automotive qualification. The forward voltage is lower (1.15 V @ 700 mA) and reverse leakage is higher (10 µA @ 200 V) compared to the RSFDL RHG.

The VS-1EFH02-M3/I and VS-2EFH02HM3/I are higher-current-rated alternatives (1 A and 2 A respectively) from the Vishay FRED Pt® series. Both parts feature significantly lower reverse recovery times (16 ns and 25 ns respectively) and lower reverse leakage currents (2 µA @ 200 V). The VS-2EFH02HM3/I carries AEC-Q101 automotive qualification. These parts support extended operating temperature ranges (-65°C to 175°C) compared to the RSFDL RHG (-55°C to 150°C).

Selection of similar parts is appropriate when the application can accommodate higher current ratings, lower reverse recovery times, or extended temperature ranges. All similar parts maintain ROHS3 compliance and DO-219AB package compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. The RSFDL R3G is a parametric equivalent with identical voltage rating (200 V), current rating (500 mA), forward voltage (1.3 V @ 500 mA), and reverse recovery time (150 ns). The primary difference is packaging format (Cut Tape versus unspecified format). Both parts are ROHS3 Compliant and use the DO-219AB package.

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

A: Both parts are parametric equivalents with identical electrical specifications. The RSFDL is designated as Not For New Designs and is supplied in Tape & Reel format with higher inventory (13,300 pieces). The RSFDL R3G is designated as Active and is supplied in Cut Tape format with lower inventory (725 pieces). For new design implementations, the RSFDL R3G is the preferred selection.

Q: Can the VS-1EFH02-M3/I or VS-2EFH02HM3/I be used in place of the RSFDL RHG?

A: These parts are similar but not parametric equivalents. They maintain the 200 V reverse voltage rating and DO-219AB package but differ in current rating (1 A and 2 A respectively versus 500 mA), reverse recovery time (16 ns and 25 ns versus 150 ns), and reverse leakage current (2 µA versus 5 µA). These parts are suitable for applications where higher current capacity or faster switching characteristics are beneficial or where the application can accommodate these differences. Both parts support extended operating temperature ranges (-65°C to 175°C).

Q: Is the RS07D-GS08 suitable as a substitute for the RSFDL RHG?

A: The RS07D-GS08 is a similar part with the same 200 V reverse voltage and 500 mA current rating in a DO-219AB package. It differs in forward voltage (1.15 V @ 700 mA versus 1.3 V @ 500 mA) and reverse leakage current (10 µA versus 5 µA). The RS07D-GS08 carries AEC-Q101 automotive qualification and is suitable for applications where automotive-grade components are required.

Q: What packaging formats are available for equivalent parts?

A: The RSFDL RHG is supplied in an unspecified format. Parametric equivalents are available in Tape & Reel format (RSFDL) and Cut Tape format (RSFDL R3G). All similar parts from Vishay are supplied in Tape & Reel format. Selection should be based on manufacturing process requirements and assembly equipment compatibility.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. The RSFDL RHG and all listed substitute parts (RSFDL, RSFDL R3G, RS07D-GS08, VS-1EFH02-M3/I, VS-2EFH02HM3/I) are ROHS3 Compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference in operating temperature range between the RSFDL RHG and the Vishay alternatives?

A: The RSFDL RHG operates from -55°C to 150°C junction temperature. The Vishay parts (RS07D-GS08, VS-1EFH02-M3/I, VS-2EFH02HM3/I) operate from -55°C to 150°C (RS07D-GS08) or -65°C to 175°C (VS-1EFH02-M3/I and VS-2EFH02HM3/I). The extended temperature range of the Vishay FRED Pt® series may be advantageous for applications requiring operation at elevated temperatures.

Q: Can parametric equivalents be interchanged without circuit modification?

A: Yes. Parametric equivalents (RSFDL, RSFDL R3G) maintain identical electrical specifications and can be interchanged without circuit modification. The only consideration is packaging format compatibility with assembly equipment.
