ES1GLHRUG Equivalent & Substitute Parts

Part Overview

The ES1GLHRUG 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, inventory constraints occur, or alternative packaging formats are required for manufacturing processes. The ES1GLHRUG is available in limited quantities (946 Pcs), making knowledge of equivalent alternatives essential for design continuity and supply chain management.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1GLHRUG is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C
RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

Reverse Recovery Time (trr): Variations within fast recovery classification (≤ 500 ns)
Capacitance @ Vr, F: Minor variations acceptable within same diode technology class
Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable for the same electrical component

The substitute parts ES1GL, ES1GL RVG, and HS1GL RVG all meet the mandatory matching criteria and are therefore classified as parametric equivalents. Differences in packaging format and inventory availability distinguish these alternatives for specific procurement scenarios.

Engineering Selection Recommendations

ES1GL RVG is the primary substitute for ES1GLHRUG. Both components share identical electrical specifications and are classified as Active products. The ES1GL RVG is available in Tape & Reel (TR) packaging format with 4,619 units in stock, providing adequate supply for production requirements. This part maintains full compliance with ROHS3 and AEC-Q101 automotive qualification standards.

HS1GL RVG is a secondary substitute option. While it maintains the same voltage, current, and temperature ratings, it exhibits a longer reverse recovery time (50 ns versus 35 ns) and higher capacitance (15 pF versus 8 pF). The HS1GL RVG is classified as Active with 18,316 units available in inventory. This part is suitable for applications where the increased reverse recovery time and capacitance do not impact circuit performance.

ES1GL is available in Cut Tape (CT) and Digi-Reel® packaging formats with the highest inventory level (95,300 units). However, this part is classified as "Not For New Designs," limiting its use to legacy system support or replacement applications only. The ES1GL maintains identical electrical specifications to the ES1GLHRUG.

For new design implementations, ES1GL RVG is the recommended substitute. For high-volume procurement or legacy system maintenance, ES1GL provides maximum availability. HS1GL RVG serves as an alternative when the specified reverse recovery time and capacitance variations are acceptable within circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GLHRUG in automotive applications?

A: Yes. Both parts are rated for 400 V DC reverse voltage, 1 A average rectified current, and carry AEC-Q101 automotive qualification. The ES1GL RVG is classified as Active product status, making it suitable for new automotive designs. The primary difference is packaging format: ES1GLHRUG uses standard reel packaging while ES1GL RVG uses Tape & Reel (TR) format.

Q: What is the significance of the "Not For New Designs" status on ES1GL?

A: This designation indicates the part is in mature or declining production phase. While ES1GL maintains identical electrical specifications to ES1GLHRUG, it should not be selected for new circuit designs. ES1GL is appropriate only for replacement or repair of existing systems already using this part number.

Q: Are there electrical performance differences between ES1GL RVG and HS1GL RVG?

A: Yes. The HS1GL RVG has a reverse recovery time of 50 ns compared to 35 ns for ES1GL RVG, and capacitance of 15 pF versus 8 pF. Both values remain within acceptable ranges for general-purpose rectification. The selection between these parts depends on circuit-specific requirements for switching speed and capacitive loading.

Q: What packaging formats are available for these substitute parts?

A: ES1GLHRUG is supplied in standard reel format. ES1GL RVG and HS1GL RVG are supplied in Tape & Reel (TR) format. ES1GL is available in Cut Tape (CT) and Digi-Reel® formats. All formats contain the same electrical component in DO-219AB Sub SMA package and are compatible with standard surface mount assembly equipment.

Q: Do all substitute parts meet RoHS and REACH compliance requirements?

A: Yes. ES1GL, ES1GL RVG, and HS1GL RVG are all ROHS3 Compliant and REACH Unaffected. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute part should be selected for maximum inventory availability?

A: ES1GL offers the highest inventory level at 95,300 units. However, due to its "Not For New Designs" status, it is restricted to legacy applications. For new designs requiring maximum availability with Active product status, HS1GL RVG provides 18,316 units in stock.
