ES1GL M2G Equivalent & Substitute Parts

Part Overview

The ES1GL M2G 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 part is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the ES1GL M2G reaches end-of-life status, when packaging format requirements change from Tape & Reel to alternative formats, or when design revisions require alternative qualified sources. The parts listed below provide electrical and mechanical equivalence within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the ES1GL M2G 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, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, 35 ns reverse recovery time, and 5 µA reverse leakage current at 400 V. These parts differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel variants) or minor capacitance measurement conditions. Parametric equivalents include ES1GL, ES1GL RVG, and HS1GL RVG.

Similar Parts share the same 400 V reverse voltage rating and DO-219AB package but operate at reduced current ratings (700 mA versus 1 A) and exhibit different recovery characteristics. These parts include S07G-GS08 and S07G-GS18 from Vishay General Semiconductor - Diodes Division. Similar parts are suitable for applications where the lower current rating satisfies design requirements.

The key parameters determining substitution eligibility are: reverse voltage rating, average rectified current capacity, forward voltage drop, reverse recovery time, and package type.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1GL RVG is the primary direct replacement for ES1GL M2G. Both parts maintain Active product status, identical electrical specifications, and Tape & Reel packaging format. ES1GL RVG is suitable for new designs and production applications requiring the same performance envelope.

HS1GL RVG is an alternative parametric equivalent with Active product status. This part exhibits a 50 ns reverse recovery time compared to the 35 ns specification of ES1GL M2G. This difference is acceptable in applications where recovery speed is not a critical constraint. HS1GL RVG is qualified to the same temperature range and compliance standards.

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part carries "Not For New Designs" product status and should be used only for legacy system maintenance or repair applications where the original packaging format is unavailable.

For Current-Reduced Applications:

S07G-GS08 and S07G-GS18 are suitable substitutes only when the application current requirement does not exceed 700 mA. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and carry Active product status with AEC-Q101 automotive qualification. These parts exhibit standard recovery characteristics (1.8 µs) compared to the fast recovery specification of ES1GL M2G. Selection between S07G-GS08 and S07G-GS18 depends on reverse leakage current measurement conditions at the specified voltage rating.

All substitute parts listed maintain RoHS3 compliance, MSL 1 rating, and DO-219AB package compatibility with the original ES1GL M2G.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GL M2G in production?

A: Yes. ES1GL RVG is a parametric equivalent with identical electrical specifications (400 V, 1 A, 1.3 V forward drop, 35 ns recovery time) and Active product status. Both parts use Tape & Reel packaging and DO-219AB case format. No circuit modifications are required.

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

A: Both parts are parametric equivalents with identical electrical performance. The primary difference is packaging format: ES1GL is supplied in Cut Tape and Digi-Reel formats, while ES1GL RVG uses Tape & Reel. Additionally, ES1GL carries "Not For New Designs" status, limiting its use to legacy applications.

Q: Why does HS1GL RVG have a different reverse recovery time (50 ns vs. 35 ns)?

A: HS1GL RVG is manufactured from a different base product series (HS1G versus ES1G) and exhibits slower recovery characteristics. This difference does not affect voltage or current ratings. Selection depends on whether the application circuit requires the faster 35 ns recovery specification or can tolerate the 50 ns performance.

Q: Can S07G-GS08 replace ES1GL M2G in all applications?

A: No. S07G-GS08 is rated for 700 mA average rectified current, compared to 1 A for ES1GL M2G. This part is suitable only for applications where the current requirement does not exceed 700 mA. Additionally, S07G-GS08 exhibits standard recovery characteristics (1.8 µs) rather than fast recovery (35 ns), which may affect circuit performance in high-frequency switching applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed—ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18—are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity level.

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

A: Both parts are identical except for reverse leakage current measurement conditions. S07G-GS08 specifies 10 µA leakage at 400 V, while S07G-GS18 specifies 10 µA leakage at 200 V. Both parts are rated for 400 V maximum reverse voltage and 700 mA current.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) affects only handling, storage, and assembly processes. Electrical specifications remain identical across all packaging variants of the same part number.

Q: Which substitute part has the highest inventory availability?

A: S07G-GS08 has the highest inventory at 658,490 pieces. ES1GL has 95,300 pieces. ES1GL RVG has 4,619 pieces. HS1GL RVG has 18,316 pieces. Inventory levels should be verified with the supplier for current availability.
