ES1GLHMQG Equivalent & Substitute Parts

Part Overview

The ES1GLHMQG 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 carries automotive-grade qualification under AEC-Q101 standards.

Substitute parts become necessary when the primary part number reaches end-of-life status, when specific packaging configurations are required for manufacturing processes, or when inventory constraints necessitate alternative sourcing from the same manufacturer's product line. The ES1GLHMQG maintains full electrical and mechanical compatibility with designated substitute part numbers that share identical core electrical specifications and package geometry.

Engineering Selection Recommendations

ES1GL RVG is the primary recommended substitute for new designs and ongoing production. This part maintains Active product status, identical electrical specifications to the ES1GLHMQG, and is supplied in Tape & Reel packaging suitable for automated assembly processes. ES1GL RVG carries full AEC-Q101 automotive qualification and ROHS3 compliance.

HS1GL RVG serves as an alternative substitute with Active product status. This part exhibits minor parameter variations: reverse recovery time of 50 ns (versus 35 ns) and capacitance of 15 pF (versus 8 pF). These variations remain within acceptable tolerances for general-purpose rectification applications while maintaining all voltage, current, and temperature specifications. HS1GL RVG is available in higher inventory quantities and provides supply chain redundancy.

ES1GL is designated as Not For New Designs and should be used only for legacy system maintenance or repair applications where the original part number must be maintained. This part is available in Cut Tape and Digi-Reel packaging configurations.

All three substitute parts share identical DO-219AB package geometry, surface mount mounting type, and thermal operating range, ensuring direct mechanical and thermal compatibility with the ES1GLHMQG in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GLHMQG in production assembly?

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 package geometry (DO-219AB Sub SMA). The Tape & Reel packaging format is compatible with standard surface mount assembly equipment.

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

A: Both parts share identical electrical specifications. The primary difference is packaging format: ES1GL is supplied in Cut Tape and Digi-Reel configurations, while ES1GL RVG is supplied in Tape & Reel format. ES1GL carries Not For New Designs status, whereas ES1GL RVG is Active. For new designs, ES1GL RVG is the appropriate selection.

Q: Why does HS1GL RVG show different reverse recovery time and capacitance values?

A: HS1GL RVG exhibits a reverse recovery time of 50 ns (compared to 35 ns in ES1GLHMQG) and capacitance of 15 pF (compared to 8 pF). These variations reflect different semiconductor process technology within the same voltage and current rating class. Both specifications remain within acceptable operating parameters for general-purpose rectification. The selection between ES1GL RVG and HS1GL RVG depends on specific circuit timing requirements and frequency response characteristics.

Q: Are all substitute parts automotive-qualified?

A: ES1GLHMQG and ES1GL RVG carry explicit AEC-Q101 automotive qualification. HS1GL RVG is manufactured by Taiwan Semiconductor Corporation with ROHS3 compliance and automotive-grade classification. All three parts meet automotive reliability standards.

Q: What packaging options are available for each substitute part?

A: ES1GLHMQG is supplied in standard packaging (not specified in detail). ES1GL is available in Cut Tape (CT) and Digi-Reel formats. ES1GL RVG and HS1GL RVG are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: Can these parts be used interchangeably in existing designs without circuit modification?

A: Yes, for general-purpose rectification applications. All substitute parts maintain identical voltage ratings (400 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), and operating temperature range (-55°C to 150°C). Circuit designs that do not impose strict timing constraints on reverse recovery time or frequency-dependent impedance characteristics will operate identically with any of the three substitute parts.

Q: What is the inventory status for each part?

A: ES1GLHMQG has 831 pieces in stock. ES1GL has 95,300 pieces available. ES1GL RVG has 4,619 pieces in stock. HS1GL RVG has 18,316 pieces available. Higher inventory levels for ES1GL and HS1GL RVG provide improved supply chain availability for ongoing production requirements.
