Substitute Part Grouping Explanation

Substitution eligibility for the ES1GLHR3G is determined by strict adherence to the following electrical and mechanical 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
RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Current - Reverse Leakage @ Vr: 5 µA @ 400 V
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical values for primary substitution criteria. Variations in reverse recovery time (trr) and junction capacitance do not preclude substitution when all primary electrical ratings and package specifications remain constant.

Engineering Selection Recommendations

ES1GL RVG is the primary substitute for ES1GLHR3G. Both parts maintain Active product status and share identical electrical specifications across all critical parameters. The packaging format differs (Tape & Reel for both), making this substitution suitable for high-volume manufacturing environments. This part number is recommended for new designs requiring the ES1GLHR3G specification.

HS1GL RVG is a secondary substitute that maintains all primary electrical and mechanical compatibility criteria. This part exhibits a longer reverse recovery time (50 ns versus 35 ns) and higher junction capacitance (15 pF versus 8 pF). Despite these parameter variations, HS1GL RVG remains electrically compatible within the DO-219AB package specification and meets all compliance requirements. This part number is suitable for applications where the extended reverse recovery time does not impact circuit performance.

ES1GL is a parametric equivalent with identical electrical specifications but carries Not For New Designs product status. This part number is available in Cut Tape and Digi-Reel packaging formats. ES1GL is suitable only for replacement or repair of existing assemblies and is not recommended for new product development.

All substitute parts maintain ROHS3 compliance, AEC-Q101 qualification (where applicable), and MSL 1 moisture sensitivity rating, ensuring compatibility with automotive and industrial manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG directly replace ES1GLHR3G in production?

A: Yes. ES1GL RVG maintains identical electrical specifications for voltage rating (400 V), current rating (1 A), forward voltage drop (1.3 V @ 1 A), reverse leakage current (5 µA @ 400 V), and reverse recovery time (35 ns). Both parts use the DO-219AB package with Surface Mount configuration. The primary difference is packaging format (Tape & Reel for both), which does not affect electrical performance or circuit compatibility.

Q: What is the difference between ES1GLHR3G and HS1GL RVG?

A: Both parts share identical voltage ratings (400 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), and reverse leakage specifications (5 µA @ 400 V). HS1GL RVG exhibits a reverse recovery time of 50 ns compared to 35 ns for ES1GLHR3G, and junction capacitance of 15 pF versus 8 pF. These parameter variations do not affect substitution eligibility when the application circuit tolerates the extended recovery time and higher capacitance values.

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

A: ES1GL carries Not For New Designs product status, indicating that Taiwan Semiconductor Corporation has designated this part number for legacy support only. New product development should utilize ES1GL RVG or HS1GL RVG, both of which maintain Active status and identical electrical specifications.

Q: Are all substitute parts available in the same packaging format?

A: No. ES1GLHR3G and ES1GL RVG are supplied in Tape & Reel (TR) packaging. ES1GL is available in Cut Tape (CT) and Digi-Reel® formats. HS1GL RVG is supplied in Tape & Reel (TR) packaging. Selection of packaging format depends on manufacturing equipment compatibility and assembly process requirements.

Q: Do all substitute parts meet automotive qualification standards?

A: ES1GLHR3G carries AEC-Q101 automotive qualification. The substitute parts ES1GL RVG and HS1GL RVG maintain identical compliance certifications and RoHS3 status, ensuring compatibility with automotive manufacturing processes and supply chain requirements.

Q: What is the impact of higher capacitance in HS1GL RVG?

A: HS1GL RVG exhibits junction capacitance of 15 pF at 4 V, 1 MHz compared to 8 pF for ES1GLHR3G. This parameter variation affects high-frequency circuit behavior and switching characteristics. Applications operating at frequencies where diode capacitance significantly impacts performance should evaluate circuit simulation results before substitution.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. All substitute parts maintain identical DO-219AB package geometry, Surface Mount configuration, and operating temperature range (-55°C to 150°C). Electrical specifications for voltage, current, and forward voltage drop are identical across ES1GLHR3G, ES1GL RVG, and HS1GL RVG, enabling direct substitution in existing circuit designs.
