ES1GL RHG Equivalent & Substitute Parts

Part Overview

The ES1GL RHG 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 switching power supply and general rectification applications.

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 permits selection from qualified alternatives that meet the same electrical specifications.

Substitute Part Grouping Explanation

Substitution of the ES1GL RHG is determined by strict equivalence across the following critical parameters:

Parametric Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C
RoHS Status: ROHS3 Compliant

Parts are grouped into two categories:

Parametric Equivalents maintain identical electrical ratings and performance characteristics. These parts differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel) or minor variations in reverse recovery time and capacitance that remain within acceptable operating ranges for the same application class.

Similar Parts share the same package and voltage rating but differ in current rating (700 mA versus 1 A) or recovery speed classification. These parts are suitable for applications with lower current requirements or where standard recovery speed is acceptable.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1GL RVG is the recommended parametric equivalent for the ES1GL RHG. Both parts are manufactured by Taiwan Semiconductor Corporation, maintain Active product status, and are ROHS3 compliant. The ES1GL RVG is supplied in Tape & Reel format, which is standard for high-volume manufacturing environments. Reverse recovery time remains at 35 nanoseconds, ensuring identical switching performance in fast recovery applications.

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part carries "Not For New Designs" status, making it suitable only for legacy system maintenance or repair applications where the original specification must be maintained.

HS1GL RVG is a parametric equivalent with a reverse recovery time of 50 nanoseconds, which remains within the fast recovery classification (≤ 500 ns). This part is Active status and ROHS3 compliant. The extended reverse recovery time introduces minimal performance variation in most general-purpose rectification circuits.

For Current-Limited Applications:

S07G-GS08 and S07G-GS18 are similar parts manufactured by Vishay General Semiconductor - Diodes Division. Both are rated for 700 mA average rectified current (versus 1 A for the ES1GL RHG) and feature standard recovery speed classification (1.8 µs reverse recovery time). These parts are suitable for applications where the circuit current requirement does not exceed 700 mA and where standard recovery speed is acceptable. Both parts carry AEC-Q101 automotive qualification and Active product status.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GL RHG?

A: Yes. ES1GL RVG is a parametric equivalent with identical electrical ratings: 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage at 1 A, and 35 nanosecond reverse recovery time. The difference is packaging format (Tape & Reel versus the original format). Both are ROHS3 compliant and Active status.

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

A: Both parts share the same voltage and current ratings and package type (DO-219AB). The primary difference is reverse recovery time: ES1GL RHG has 35 ns while HS1GL RVG has 50 ns. Both remain classified as fast recovery diodes. HS1GL RVG also has higher capacitance (15 pF versus 8 pF at 4 V, 1 MHz). These differences are acceptable for general-purpose rectification applications.

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

A: S07G-GS08 is suitable only for applications where the circuit current requirement does not exceed 700 mA. The ES1GL RHG is rated for 1 A, while S07G-GS08 is rated for 700 mA. Additionally, S07G-GS08 features standard recovery speed (1.8 µs) rather than fast recovery (35 ns). Use S07G-GS08 only when both current and speed requirements are compatible with these lower specifications.

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

A: "Not For New Designs" indicates that this part number is available for existing applications and legacy system support but should not be selected for new circuit designs. For new designs, select ES1GL RVG or HS1GL RVG, both of which carry Active product status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—ES1GL RHG, ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18—are ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available for the ES1GL RHG equivalent?

A: Parametric equivalents are available in three packaging formats: Cut Tape (CT) & Digi-Reel® (ES1GL), and Tape & Reel (TR) (ES1GL RVG and HS1GL RVG). Select the packaging format based on manufacturing process requirements and component handling equipment.

Q: Do all substitute parts use the same DO-219AB package?

A: Yes. All listed parts—ES1GL RHG, ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18—use the DO-219AB package (Sub SMA or SMF designation). This ensures mechanical and thermal compatibility in surface mount applications.
