ES1GLHRFG Equivalent & Substitute Parts

Part Overview

The ES1GLHRFG 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 meets automotive-grade qualification standards under AEC-Q101.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or alternative packaging formats are required for manufacturing processes. The ES1GLHRFG maintains full electrical and mechanical compatibility with designated substitute part numbers that share identical core electrical specifications and package geometry.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1GLHRFG is determined by strict equivalence across the following critical parameters:

Mandatory 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
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variance: Reverse Recovery Time (trr) and Capacitance @ Vr, F may vary within the fast recovery diode classification (≤500 ns for speeds >200 mA) without affecting functional substitution. These parameters represent performance characteristics that do not compromise circuit compatibility when the primary electrical ratings remain identical.

All substitute parts listed maintain identical voltage and current ratings, forward voltage characteristics, and thermal operating range. Packaging format variations (Cut Tape, Tape & Reel) represent distribution methods only and do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Selection: ES1GLHRFG The ES1GLHRFG maintains Active product status and is the preferred selection for new designs and production applications. This part number is supported by current manufacturing processes and inventory availability.

Secondary Selection: ES1GL RVG The ES1GL RVG is electrically identical to the ES1GLHRFG with Active product status. This part number is supplied in Tape & Reel (TR) packaging format, suitable for high-volume automated assembly operations. Selection of ES1GL RVG is appropriate when tape and reel distribution is required for manufacturing efficiency.

Tertiary Selection: HS1GL RVG The HS1GL RVG is electrically equivalent with Active product status and Tape & Reel packaging. This part exhibits a reverse recovery time of 50 ns (compared to 35 ns for ES1GLHRFG) and capacitance of 15 pF (compared to 8 pF for ES1GLHRFG). These parameter variations remain within fast recovery diode specifications and do not compromise functional compatibility. HS1GL RVG is suitable for applications where the extended reverse recovery time and increased capacitance do not present circuit constraints.

Not Recommended for New Designs: ES1GL The ES1GL carries Not For New Designs product status and should not be selected for new circuit development or production applications. This part number is available in Cut Tape and Digi-Reel packaging formats and is retained for legacy system support and repair applications only.

All substitute parts maintain ROHS3 compliance, AEC-Q101 automotive qualification (where applicable), and identical thermal operating ranges. Selection among active alternatives is based on packaging format requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GLHRFG in production assembly?

A: Yes. ES1GL RVG is electrically and mechanically identical to ES1GLHRFG. Both parts share identical voltage ratings (400 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), and package geometry (DO-219AB Sub SMA). The primary difference is packaging format: ES1GL RVG is supplied in Tape & Reel format, while ES1GLHRFG is supplied in Cut Tape format. Selection depends on assembly equipment compatibility and manufacturing process requirements.

Q: What is the significance of the reverse recovery time difference between ES1GLHRFG (35 ns) and HS1GL RVG (50 ns)?

A: Reverse recovery time represents the interval required for the diode to transition from forward conduction to reverse blocking state. The 15 ns difference between these parts falls within the fast recovery diode classification (≤500 ns). This parameter affects switching speed in high-frequency applications. HS1GL RVG is suitable for applications where the extended recovery time does not introduce unacceptable switching losses or electromagnetic interference. Circuit-specific analysis is required to determine if this parameter variance is acceptable for the intended application.

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

A: ES1GL carries Not For New Designs status, indicating that Taiwan Semiconductor Corporation has designated this part number for legacy support only. New circuit designs should utilize ES1GLHRFG, ES1GL RVG, or HS1GL RVG, all of which maintain Active product status. ES1GL remains available for repair and maintenance of existing systems.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES1GL, ES1GL RVG, and HS1GL RVG) maintain ROHS3 compliance status. This certification applies to all packaging formats and distribution methods for each part number.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Tape & Reel (TR) represent different distribution and handling formats for surface mount components. Cut Tape packaging supplies components in individual tape segments, suitable for manual assembly or small-batch operations. Tape & Reel packaging supplies components on continuous reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components with identical electrical specifications. Selection is based on assembly process requirements and equipment compatibility.

Q: Can HS1GL RVG be used in automotive applications?

A: HS1GL RVG is manufactured by Taiwan Semiconductor Corporation and meets the same RoHS3 and REACH compliance standards as ES1GLHRFG. However, the provided data does not specify AEC-Q101 automotive qualification status for HS1GL RVG. Verification of automotive qualification requirements for the specific application is necessary before selection for automotive systems.

Q: What does Moisture Sensitivity Level (MSL) 1 (Unlimited) indicate?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or baking procedures prior to assembly. Standard storage conditions are acceptable for all listed substitute parts.
