ES1GL RTG Equivalent & Substitute Parts

Part Overview

The ES1GL RTG 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 (DO-219AB). 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 applications requiring rapid switching performance.

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 flexibility demands component sourcing from multiple suppliers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

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

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 400 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage at 1 A, 35 nanosecond reverse recovery time, and DO-219AB package format. These parts differ only in packaging configuration (Cut Tape, Digi-Reel, or Tape & Reel) or minor manufacturing variants. Parametric equivalents include ES1GL, ES1GL RVG, and HS1GL RVG.

Similar Parts share the same 400 V reverse voltage rating and DO-219AB package but differ in one or more of the following parameters: average rectified current rating, reverse recovery time, or reverse leakage current. These parts are suitable for applications where the lower current rating or different recovery characteristics do not conflict with circuit requirements. Similar parts include RS07G-GS08, S07G-GS08, and S07G-GS18.

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 Direct Replacement (Parametric Equivalents):

ES1GL RVG is the recommended primary substitute for ES1GL RTG. Both parts maintain identical electrical specifications including 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage, and 35 nanosecond reverse recovery time. ES1GL RVG carries Active product status and is available in Tape & Reel packaging format. This part is suitable for new designs and high-volume manufacturing processes.

HS1GL RVG is an alternative parametric equivalent with Active product status. The reverse recovery time specification differs at 50 nanoseconds compared to 35 nanoseconds in the ES1GL RTG. This variance is acceptable in applications where switching speed is not a critical constraint. HS1GL RVG offers the highest inventory availability at 18,316 pieces.

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part is designated as Not For New Designs and should be used only for legacy system maintenance or repair applications where the original part number must be maintained.

For Current-Limited Applications (Similar Parts):

RS07G-GS08 (Vishay) is suitable for applications where the circuit current requirement does not exceed 500 mA. This part maintains the 400 V reverse voltage rating and DO-219AB package. The reverse recovery time of 150 nanoseconds is slower than the ES1GL RTG, making it appropriate for standard-speed rectification circuits. AEC-Q101 automotive qualification is provided.

S07G-GS08 and S07G-GS18 (Vishay) are suitable for applications where the circuit current requirement does not exceed 700 mA. Both parts maintain the 400 V reverse voltage rating and DO-219AB package. The reverse recovery time of 1.8 microseconds indicates standard recovery characteristics, appropriate for lower-frequency rectification applications. Both parts carry AEC-Q101 automotive qualification and offer high inventory availability.

All substitute parts listed maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, matching the regulatory profile of the ES1GL RTG.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GL RTG in all applications?

A: Yes. ES1GL RVG maintains identical electrical specifications across all critical parameters: 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage at 1 A, and 35 nanosecond reverse recovery time. The only difference is packaging format (Tape & Reel versus the original configuration). Both parts are surface mount in DO-219AB package and suitable for identical circuit applications.

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

A: The primary difference is reverse recovery time: ES1GL RTG specifies 35 nanoseconds while HS1GL RVG specifies 50 nanoseconds. All other electrical parameters are identical. HS1GL RVG is suitable for applications where the slightly slower recovery time does not impact circuit performance. HS1GL RVG offers higher inventory availability.

Q: Can RS07G-GS08 replace ES1GL RTG?

A: RS07G-GS08 is not a direct replacement. While both parts share the 400 V reverse voltage rating and DO-219AB package, RS07G-GS08 is rated for only 500 mA average rectified current compared to 1 A for ES1GL RTG. RS07G-GS08 is suitable only for applications where the circuit current requirement does not exceed 500 mA.

Q: What is the difference between S07G-GS08 and S07G-GS18?

A: Both parts are electrically identical with 400 V reverse voltage and 700 mA average rectified current ratings. The difference is in reverse leakage current specification: S07G-GS08 specifies 10 µA at 400 V, while S07G-GS18 specifies 10 µA at 200 V. Both parts are suitable for applications requiring up to 700 mA current and standard recovery characteristics.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed—ES1GL RTG, ES1GL, ES1GL RVG, HS1GL RVG, RS07G-GS08, S07G-GS08, and S07G-GS18—are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). All parts are REACH Unaffected.

Q: Which substitute part has the fastest recovery time?

A: ES1GL RTG and ES1GL RVG both specify 35 nanosecond reverse recovery time, the fastest among all listed parts. HS1GL RVG specifies 50 nanoseconds. Vishay parts (RS07G-GS08, S07G-GS08, S07G-GS18) have slower recovery times ranging from 150 nanoseconds to 1.8 microseconds.

Q: Can I use S07G-GS08 in place of ES1GL RTG?

A: S07G-GS08 is not suitable as a direct replacement. While both parts share the 400 V reverse voltage rating and DO-219AB package, S07G-GS08 is rated for 700 mA average rectified current (versus 1 A for ES1GL RTG) and has a reverse recovery time of 1.8 microseconds (versus 35 nanoseconds for ES1GL RTG). S07G-GS08 is appropriate only for lower-current, standard-speed rectification applications.

Q: What is the product status of ES1GL?

A: ES1GL is designated as Not For New Designs. This part should be used only for legacy system maintenance, repair, or replacement of existing installations. For new designs, ES1GL RVG or HS1GL RVG are the recommended alternatives.

Q: Are there inventory differences between the substitute parts?

A: Yes. Inventory levels vary significantly: S07G-GS08 has the highest availability at 658,490 pieces, followed by S07G-GS18 at 95,100 pieces and ES1GL at 95,300 pieces. HS1GL RVG has 18,316 pieces, ES1GL RVG has 4,619 pieces, and ES1GL RTG has 804 pieces. Inventory availability may influence sourcing decisions for high-volume applications.
