Substitute Part Grouping Explanation

Substitute parts for the ES1DL RFG are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain identical or functionally equivalent electrical specifications across all critical parameters: reverse voltage (200 V), average rectified current (1 A), forward voltage drop (950 mV @ 1 A), fast recovery speed classification, package type (DO-219AB), and operating temperature range (-55°C ~ 150°C). These parts differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel) and minor variations in reverse recovery time or capacitance that do not affect circuit performance within the specified operating envelope.

Similar Parts share 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 circuit design permits operation within the alternative part's electrical specifications.

The substitution logic is based strictly on the following key parameters:

Voltage - DC Reverse (Vr) (Max): 200 V (required match)
Package / Case: DO-219AB (required match for mechanical compatibility)
Mounting Type: Surface Mount (required match)
Current - Average Rectified (Io): 1 A (preferred match for parametric equivalents)
Operating Temperature Range: -55°C ~ 150°C minimum (required match or better)

Engineering Selection Recommendations

Parametric Equivalent Selection (ES1DL and HS1DL RVG)

The ES1DL and HS1DL RVG are parametric equivalents of the ES1DL RFG, maintaining identical reverse voltage (200 V), average rectified current (1 A), forward voltage (950 mV @ 1 A), and operating temperature range (-55°C ~ 150°C). Both parts are manufactured by Taiwan Semiconductor Corporation with Active product status and ROHS3 compliance. The ES1DL differs only in packaging format (Cut Tape and Digi-Reel options available), while the HS1DL RVG exhibits a slightly higher reverse recovery time (50 ns versus 35 ns) and increased capacitance (20 pF versus 10 pF at 4 V), which remain within acceptable fast recovery classification. Selection between these parametric equivalents is determined by packaging and inventory requirements rather than electrical performance.

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

The RS07D-GS08 (Vishay) is rated for 500 mA average rectified current, representing a current derating of 50% relative to the ES1DL RFG. This part is suitable for applications where the circuit design permits operation at reduced current levels. The RS07D-GS08 exhibits higher forward voltage (1.15 V @ 700 mA) and significantly longer reverse recovery time (150 ns), and includes AEC-Q101 automotive qualification.

The VS-1EFH02-M3/I (Vishay FRED Pt® series) maintains the 1 A current rating and 200 V reverse voltage specification with improved electrical characteristics: lower forward voltage (930 mV @ 1 A), faster reverse recovery time (16 ns), and reduced reverse leakage current (2 µA @ 200 V). Operating temperature range extends to -65°C ~ 175°C. This part is suitable for direct substitution where improved performance characteristics are acceptable.

The VS-2EFH02HM3/I (Vishay FRED Pt® series) is rated for 2 A average rectified current, providing current headroom above the ES1DL RFG specification. This part exhibits fast reverse recovery time (25 ns), reduced reverse leakage current (2 µA @ 200 V), extended operating temperature range (-65°C ~ 175°C), and AEC-Q101 automotive qualification. Selection of this part is appropriate for applications requiring higher current capacity or automotive-grade reliability.

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity, and DO-219AB package compatibility with the primary part.

Frequently Asked Questions (FAQ)

Q: Can ES1DL be used as a direct replacement for ES1DL RFG?

A: Yes. The ES1DL is a parametric equivalent with identical electrical specifications: 200 V reverse voltage, 1 A average rectified current, 950 mV forward voltage @ 1 A, and -55°C ~ 150°C operating temperature range. The difference is packaging format. ES1DL is available in Cut Tape and Digi-Reel configurations, while ES1DL RFG is specified with different packaging. Both parts are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 standards.

Q: What is the difference between HS1DL RVG and ES1DL RFG?

A: The HS1DL RVG maintains the same reverse voltage (200 V), current rating (1 A), forward voltage (950 mV @ 1 A), and operating temperature range (-55°C ~ 150°C) as the ES1DL RFG. The HS1DL RVG exhibits a higher reverse recovery time (50 ns versus 35 ns) and increased capacitance (20 pF versus 10 pF at 4 V). Both parameters remain within fast recovery classification. The HS1DL RVG is available in Cut Tape packaging. Selection depends on whether the slightly slower recovery time and higher capacitance are acceptable for the application.

Q: Can RS07D-GS08 replace ES1DL RFG in all applications?

A: No. The RS07D-GS08 is rated for 500 mA average rectified current, which is 50% lower than the ES1DL RFG (1 A). This part is suitable only for applications where the circuit design permits operation at reduced current levels. The RS07D-GS08 also exhibits higher forward voltage (1.15 V @ 700 mA) and longer reverse recovery time (150 ns). The RS07D-GS08 includes AEC-Q101 automotive qualification, which the ES1DL RFG does not specify.

Q: What are the advantages of VS-1EFH02-M3/I over ES1DL RFG?

A: The VS-1EFH02-M3/I maintains the 1 A current rating and 200 V reverse voltage specification while offering improved electrical performance: lower forward voltage (930 mV @ 1 A versus 950 mV), faster reverse recovery time (16 ns versus 35 ns), and reduced reverse leakage current (2 µA versus 5 µA @ 200 V). Operating temperature range extends to -65°C ~ 175°C. These characteristics make the VS-1EFH02-M3/I suitable for applications requiring enhanced performance or extended temperature operation.

Q: When should VS-2EFH02HM3/I be selected instead of ES1DL RFG?

A: The VS-2EFH02HM3/I should be selected when the application requires higher current capacity (2 A versus 1 A) or when automotive-grade reliability (AEC-Q101 qualification) is mandated. The VS-2EFH02HM3/I also provides improved electrical characteristics: faster reverse recovery time (25 ns), reduced reverse leakage current (2 µA), and extended operating temperature range (-65°C ~ 175°C). This part is suitable for designs requiring current headroom or automotive qualification.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts specified in this document use the DO-219AB package with Surface Mount mounting type, ensuring mechanical and footprint compatibility with the ES1DL RFG. No PCB layout modifications are required for substitution.

Q: Do all substitute parts comply with ROHS3 and REACH standards?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the environmental compliance profile of the ES1DL RFG. All parts have Moisture Sensitivity Level 1 (Unlimited).

Q: What is the primary criterion for selecting a substitute part?

A: The primary criterion is matching the reverse voltage specification (200 V) and package type (DO-219AB). Secondary criteria include current rating (1 A preferred for parametric equivalents), forward voltage characteristics, reverse recovery time, and operating temperature range. Selection should be based on whether the substitute part's electrical specifications satisfy the circuit design requirements.
