ES1GL RUG Equivalent & Substitute Parts

Part Overview

The ES1GL RUG 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 is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design revisions call for equivalent electrical performance from different manufacturers or product lines.

Substitute Part Grouping Explanation

Substitution of the ES1GL RUG is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A
Package / Case: DO-219AB (Sub SMA)
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C
RoHS3 Compliance

Parametric Equivalents maintain identical electrical ratings and package specifications. These parts are direct functional replacements with only packaging format differences (Tape & Reel versus Cut Tape).

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

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1GL RVG is the recommended parametric equivalent for ES1GL RUG. Both parts are manufactured by Taiwan Semiconductor Corporation, maintain Active product status, and are RoHS3 compliant. Both are supplied in Tape & Reel packaging suitable for automated assembly processes. Electrical specifications are identical across all critical parameters.

HS1GL RVG is an alternative parametric equivalent with identical voltage and current ratings. This part differs in reverse recovery time (50 ns versus 35 ns) and junction capacitance (15 pF versus 8 pF at 4V). This part is suitable for applications where the slightly longer recovery time does not impact circuit performance.

ES1GL is available in Cut Tape and Digi-Reel packaging formats. This part carries "Not For New Designs" status and should be used only for legacy system maintenance or when specific packaging requirements mandate cut tape format.

For Current-Limited Applications (Similar Parts):

S07G-GS08 and S07G-GS18 are manufactured by Vishay General Semiconductor and are rated for 700 mA average rectified current. These parts are suitable for applications where the circuit current requirement does not exceed 700 mA. Both parts carry AEC-Q101 automotive qualification and Active product status. Recovery time is significantly longer (1.8 µs standard recovery versus 35 ns fast recovery), making these parts suitable for standard-speed rectification applications only.

Frequently Asked Questions (FAQ)

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

A: Yes. ES1GL RVG is a parametric equivalent with identical electrical specifications. The only difference is the packaging format (both are Tape & Reel). Both parts are Active status and RoHS3 compliant.

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

A: Both parts share identical voltage (400 V), current (1 A), and forward voltage specifications. HS1GL RVG has a longer reverse recovery time (50 ns versus 35 ns) and higher junction capacitance (15 pF versus 8 pF). These differences are acceptable in most general-purpose rectification circuits.

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

A: No. S07G-GS08 is rated for 700 mA maximum current, compared to 1 A for ES1GL RUG. This part is suitable only for circuits where the current requirement does not exceed 700 mA. Additionally, S07G-GS08 uses standard recovery technology (1.8 µs) versus fast recovery (35 ns), which may affect high-frequency circuit performance.

Q: Why is ES1GL marked "Not For New Designs"?

A: ES1GL carries this status designation from the manufacturer. For new designs, ES1GL RVG or HS1GL RVG should be selected instead. ES1GL remains available for legacy system support and maintenance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant. All parts also carry MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the industry standard package designation for Sub SMA surface mount diodes. All listed parts use this package, ensuring mechanical and electrical compatibility in surface mount assembly processes.

Q: Can I mix different substitute parts in the same production batch?

A: All parametric equivalents (ES1GL RVG, HS1GL RVG) are functionally interchangeable. However, similar parts (S07G-GS08, S07G-GS18) have different current ratings and recovery characteristics and should not be mixed with the primary part or parametric equivalents in the same circuit unless the design specifically accommodates the lower current rating.
