ES1GL RFG Equivalent & Substitute Parts

Part Overview

The ES1GL RFG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and features fast recovery characteristics with a reverse recovery time of 35 nanoseconds, making it suitable for high-frequency switching applications.

Identification of equivalent and substitute parts is necessary to address supply chain continuity, packaging format requirements, and design flexibility. Alternative parts may be required when the primary part number reaches end-of-life status, when specific packaging formats (Cut Tape, Digi-Reel, or Tape & Reel) are preferred for manufacturing processes, or when design specifications permit operation with comparable electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES1GL RFG are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or functionally equivalent electrical specifications across all critical parameters: 400 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, fast recovery speed (≤500 ns), and DO-219AB package format. These parts are direct functional replacements and differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel) or minor variations in capacitance measurement conditions.

Similar Parts share the same package format (DO-219AB) and reverse voltage rating (400 V) but operate at reduced current ratings (700 mA instead of 1 A) and employ standard recovery speed characteristics (>500 ns) rather than fast recovery. These parts are suitable for applications where the lower current rating is acceptable and where recovery speed is not a critical design parameter.

The key parameters determining substitution eligibility are:

• Voltage - DC Reverse (Vr) (Max): 400 V (required for all substitutes)
• Current - Average Rectified (Io): 1 A (required for parametric equivalents; 700 mA acceptable for similar parts)
• Package / Case: DO-219AB (required for all substitutes)
• Mounting Type: Surface Mount (required for all substitutes)
• Operating Temperature Range: -55°C to 150°C (required for all substitutes)

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Parametric Equivalents):

ES1GL RVG is the recommended parametric equivalent for the ES1GL RFG. Both parts maintain identical electrical specifications (400 V, 1 A, 35 ns recovery time) and are manufactured by Taiwan Semiconductor Corporation with Active product status. The ES1GL RVG differs only in packaging format (Tape & Reel instead of Sub SMA) and is suitable for high-volume manufacturing processes requiring reel-based component feeding. Both parts are ROHS3 Compliant and REACH Unaffected.

HS1GL RVG is an alternative parametric equivalent with Active product status, also manufactured by Taiwan Semiconductor Corporation. This part maintains the 400 V and 1 A ratings but specifies a reverse recovery time of 50 nanoseconds compared to 35 nanoseconds for the ES1GL RFG. This 15-nanosecond difference may impact switching frequency performance in applications where fast recovery is critical. HS1GL RVG is suitable for applications where the slightly longer recovery time is acceptable.

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part carries "Not For New Designs" product status, indicating it is in mature or declining production phase. Use of this part number is appropriate only for sustaining production of existing designs or when specific packaging format requirements mandate its selection.

For Current-Reduced Applications (Similar Parts):

S07G-GS08 and S07G-GS18 are similar parts manufactured by Vishay General Semiconductor - Diodes Division. Both are rated for 400 V reverse voltage but operate at 700 mA average rectified current (30% lower than the ES1GL RFG). These parts employ standard recovery speed (1.8 microseconds) rather than fast recovery characteristics. Selection of these parts is appropriate only when application current requirements do not exceed 700 mA and when standard recovery speed performance is acceptable. Both parts carry AEC-Q101 automotive qualification and Active product status.

Compliance and Regulatory Considerations:

All substitute parts listed maintain ROHS3 Compliance and REACH Unaffected status, consistent with the ES1GL RFG. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GL RFG in existing designs?

A: Yes. ES1GL RVG is a parametric equivalent with identical electrical specifications (400 V, 1 A, 35 ns recovery time). The difference is packaging format: ES1GL RVG is supplied in Tape & Reel format while ES1GL RFG is supplied in Sub SMA format. Both are suitable for surface mount assembly on DO-219AB package footprints. Verify that your manufacturing equipment can accommodate Tape & Reel component feeding if transitioning from Sub SMA format.

Q: What is the difference between ES1GL RVG and HS1GL RVG?

A: Both parts are parametric equivalents rated for 400 V and 1 A. The primary difference is reverse recovery time: ES1GL RVG specifies 35 nanoseconds while HS1GL RVG specifies 50 nanoseconds. In applications where switching frequency is high or where fast recovery is critical to circuit performance, ES1GL RVG is the preferred selection. HS1GL RVG is suitable for lower-frequency applications where the additional 15-nanosecond recovery time does not impact performance.

Q: Can S07G-GS08 or S07G-GS18 replace ES1GL RFG?

A: These parts are similar but not direct replacements. S07G-GS08 and S07G-GS18 are rated for 700 mA average rectified current, which is 30% lower than the 1 A rating of ES1GL RFG. Additionally, these parts employ standard recovery speed (1.8 microseconds) rather than fast recovery (35 nanoseconds). Use these parts only if your application current requirements do not exceed 700 mA and if standard recovery speed performance is acceptable. Do not use these parts in applications designed for 1 A operation or where fast recovery is required.

Q: What does "Not For New Designs" product status mean for ES1GL?

A: "Not For New Designs" indicates that ES1GL is in mature or declining production phase and is intended for sustaining production of existing designs only. New designs should utilize ES1GL RVG or HS1GL RVG, both of which carry Active product status. If ES1GL is selected for a new design, supply chain risk increases as the part may transition to obsolescence.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18) are ROHS3 Compliant and REACH Unaffected. All parts are suitable for applications requiring compliance with European Union Restriction of Hazardous Substances regulations.

Q: What is the difference between Sub SMA and Tape & Reel packaging formats?

A: Sub SMA (Subminiature SMA) refers to individual component packaging or small quantity packaging suitable for manual assembly or low-volume production. Tape & Reel format supplies components on continuous carrier tape wound on reels, designed for automated high-volume assembly equipment. Both formats contain the same component in the same DO-219AB package; the difference is in how components are supplied and fed into assembly equipment. Verify your manufacturing process requirements before selecting between these formats.

Q: Can I use HS1GL RVG in a high-frequency switching application originally designed for ES1GL RFG?

A: HS1GL RVG is suitable for high-frequency applications, but verify that the 50-nanosecond reverse recovery time (compared to 35 nanoseconds for ES1GL RFG) does not impact circuit performance. The 15-nanosecond difference may affect switching losses, electromagnetic interference characteristics, or timing-critical circuit behavior. Conduct circuit analysis or testing to confirm compatibility before production transition.

Q: What inventory levels are available for each substitute part?

A: Inventory levels are provided for reference: ES1GL RFG (948 Pcs), ES1GL (95,300 Pcs), ES1GL RVG (4,619 Pcs), HS1GL RVG (18,316 Pcs), S07G-GS08 (658,490 Pcs), and S07G-GS18 (95,100 Pcs). Inventory availability may change; verify current stock status with your component supplier before finalizing procurement decisions.
