ES1GL MQG Equivalent & Substitute Parts

Part Overview

The ES1GL MQG 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).

Alternative equivalent and substitute parts are necessary when the ES1GL MQG packaging configuration (MQG variant) is unavailable or when design requirements permit operation with modified electrical characteristics such as reduced current ratings or extended recovery times.

Substitute Part Grouping Explanation

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

Voltage Rating: All substitute parts must maintain the 400 V DC reverse voltage specification to ensure circuit protection and reliability.

Current Rating: Substitute parts rated at 1 A average rectified current are considered parametric equivalents. Parts rated at 700 mA are classified as similar substitutes and are suitable only when circuit design permits reduced current capacity.

Package and Mounting: All substitute parts use the DO-219AB package with surface mount configuration, ensuring mechanical and thermal compatibility.

Recovery Characteristics: Fast recovery diodes with reverse recovery time ≤ 500 ns are parametric equivalents. Standard recovery diodes with trr > 500 ns are classified as similar substitutes and introduce different switching behavior.

Compliance: All substitute parts maintain RoHS3 compliance and MSL 1 rating, ensuring environmental and moisture handling compatibility.

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitution):

ES1GL RVG is the primary parametric equivalent to ES1GL MQG. Both parts share identical electrical specifications including 400 V reverse voltage, 1 A current rating, 1.3 V forward voltage, and 35 ns reverse recovery time. ES1GL RVG is Active product status and available in Tape & Reel packaging. This part is suitable for direct substitution in production environments requiring reel-based component handling.

HS1GL RVG is a parametric equivalent with Active product status. The reverse recovery time is specified at 50 ns compared to 35 ns for the main part, representing a 43% increase in recovery time. This part is suitable for applications where slightly extended recovery characteristics are acceptable. Capacitance is specified at 15 pF compared to 8 pF for the main part.

ES1GL is a parametric equivalent with identical electrical specifications but carries Not For New Designs product status. This part is available in Cut Tape and Digi-Reel packaging. Use of this part is restricted to legacy design support and component replacement only.

Similar Substitutes (Conditional Substitution):

S07G-GS08 and S07G-GS18 are similar substitutes manufactured by Vishay General Semiconductor. Both parts maintain the 400 V reverse voltage rating but are rated at 700 mA average rectified current, representing a 30% reduction in current capacity. These parts employ standard recovery technology with 1.8 µs reverse recovery time, significantly longer than the 35 ns specification of the main part. These parts carry AEC-Q101 automotive qualification and are suitable only for applications where reduced current capacity and extended recovery time are acceptable design parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. ES1GL RVG is a parametric equivalent with identical electrical specifications. The primary difference is packaging format: ES1GL RVG is supplied in Tape & Reel configuration while ES1GL MQG uses a different packaging variant. Both parts meet the same electrical requirements for 400 V reverse voltage, 1 A current rating, and 35 ns recovery time.

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

A: Both parts are parametrically identical with 400 V, 1 A, and 35 ns specifications. ES1GL is classified as Not For New Designs and is supplied in Cut Tape and Digi-Reel packaging. ES1GL RVG is Active product status and supplied in Tape & Reel format. For new designs, ES1GL RVG is the preferred selection.

Q: Can HS1GL RVG replace ES1GL MQG?

A: HS1GL RVG is a parametric equivalent suitable for substitution. The reverse recovery time is 50 ns compared to 35 ns for the main part. Capacitance is 15 pF compared to 8 pF. These differences are within the parametric tolerance of the diode category and do not affect basic rectification function. Verify circuit timing requirements before substitution.

Q: Why are S07G-GS08 and S07G-GS18 listed as similar rather than parametric equivalents?

A: These Vishay parts differ in two critical parameters. Current rating is 700 mA versus 1 A for the main part, representing a 30% reduction in capacity. Reverse recovery time is 1.8 µs versus 35 ns, indicating standard recovery technology rather than fast recovery. These parts are suitable only when circuit design permits reduced current handling and extended switching times.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance certification and MSL 1 (unlimited) moisture sensitivity level, matching the environmental and handling requirements of the main part.

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

A: DO-219AB is the standardized package designation for all listed parts, ensuring mechanical compatibility with existing PCB footprints and assembly equipment. All parts use surface mount configuration with identical thermal and electrical interface characteristics.

Q: Can I use S07G-GS08 in a high-frequency switching application?

A: S07G-GS08 employs standard recovery technology with 1.8 µs reverse recovery time, making it unsuitable for high-frequency switching applications. The main part ES1GL MQG and its parametric equivalents (ES1GL RVG, HS1GL RVG) use fast recovery technology with recovery times ≤ 50 ns, appropriate for switching frequencies above 100 kHz.

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

A: ES1GL MQG: 702 pcs; ES1GL: 95,300 pcs; ES1GL RVG: 4,619 pcs; HS1GL RVG: 18,316 pcs; S07G-GS08: 658,490 pcs; S07G-GS18: 95,100 pcs. Inventory levels are subject to change and should be verified at time of procurement.
