HS1GL RUG Equivalent & Substitute Parts

Part Overview

The HS1GL RUG 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 (DO-219AB). This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range. Alternative sources and packaging configurations are available to support procurement flexibility, inventory management, and design continuity.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: reverse voltage (400 V), average rectified current (1 A), forward voltage (1.3 V @ 1 A), package type (DO-219AB Sub SMA), mounting configuration (surface mount), and operating temperature range (-55°C to 150°C). These parts differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel) or minor performance enhancements (reverse recovery time, capacitance). Parametric equivalents include ES1GL, ES1GL RVG, and HS1GL RVG.

Similar Parts share the same package type (DO-219AB) and reverse voltage rating (400 V) but operate at reduced average rectified current (700 mA instead of 1 A). These parts are suitable for applications where current requirements do not exceed 700 mA. Similar parts include S07G-GS08 and S07G-GS18 from Vishay General Semiconductor - Diodes Division.

Substitution eligibility is determined by:

Reverse voltage rating equal to or greater than 400 V
Average rectified current equal to or greater than application requirement
Package compatibility (DO-219AB Sub SMA)
Surface mount mounting type
Operating temperature range encompassing -55°C to 150°C

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

HS1GL RVG is the primary parametric equivalent, maintaining identical reverse recovery time (50 ns) and forward voltage characteristics (1.3 V @ 1 A) as the HS1GL RUG. Both parts share the same base product number (HS1G) and are Active product status. HS1GL RVG is available in Tape & Reel packaging with 18,316 units in stock, providing higher inventory availability than the original part.

ES1GL RVG is an alternative parametric equivalent from Taiwan Semiconductor Corporation with improved reverse recovery time (35 ns) and is Active product status. This part is suitable for applications where faster recovery characteristics provide performance benefits. ES1GL RVG is available in Tape & Reel packaging with 4,619 units in stock.

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats with 95,300 units in stock. This part carries "Not For New Designs" product status and should be used only for legacy system support or maintenance applications.

For Current-Limited Applications (Similar Parts):

S07G-GS08 and S07G-GS18 are suitable substitutes for applications where average rectified current does not exceed 700 mA. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and carry Active product status with AEC-Q101 automotive qualification. These parts feature standard recovery characteristics (1.8 µs) and lower capacitance (4 pF @ 4 V, 1 MHz) compared to the HS1GL RUG. S07G-GS08 and S07G-GS18 are available in high inventory quantities (658,490 and 95,100 units respectively).

All substitute parts maintain ROHS3 compliance, MSL 1 (unlimited), and operating temperature range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG replace HS1GL RUG in all applications?

A: ES1GL RVG is a parametric equivalent with identical voltage and current ratings (400 V, 1 A). The primary difference is improved reverse recovery time (35 ns versus 50 ns). This faster recovery characteristic is compatible with all applications designed for HS1GL RUG and provides enhanced performance in high-frequency switching circuits. Both parts use DO-219AB Sub SMA packaging and are surface mount compatible.

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

A: HS1GL RVG and HS1GL RUG are parametric equivalents with identical electrical specifications. The difference is packaging format: HS1GL RUG is supplied in Sub SMA format, while HS1GL RVG is supplied in Tape & Reel (TR) format. Both parts share the same base product number (HS1G), reverse voltage (400 V), current rating (1 A), and reverse recovery time (50 ns). Selection between these parts depends on procurement and assembly requirements.

Q: Can S07G-GS08 be used as a direct replacement for HS1GL RUG?

A: S07G-GS08 is a similar part suitable only for applications where average rectified current does not exceed 700 mA. The HS1GL RUG is rated for 1 A, while S07G-GS08 is rated for 700 mA. If the application requires the full 1 A current capacity, S07G-GS08 is not suitable. S07G-GS08 also features standard recovery characteristics (1.8 µs) compared to fast recovery (50 ns) for HS1GL RUG, which may affect performance in high-frequency applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). All parts are suitable for applications requiring environmental compliance certification.

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

A: ES1GL and ES1GL RVG are parametric equivalents with identical electrical specifications (400 V, 1 A, 1.3 V forward voltage). The difference is packaging format and product status. ES1GL is available in Cut Tape (CT) and Digi-Reel format with "Not For New Designs" status, while ES1GL RVG is available in Tape & Reel (TR) format with Active product status. For new designs, ES1GL RVG is the recommended choice.

Q: Can I use HS1GL RVG for high-frequency switching applications?

A: HS1GL RVG is suitable for high-frequency switching applications. It features fast recovery characteristics with 50 ns reverse recovery time and is rated for 400 V and 1 A. The operating temperature range (-55°C to 150°C) and capacitance specification (15 pF @ 4 V, 1 MHz) support high-frequency operation. For applications requiring even faster recovery, ES1GL RVG with 35 ns reverse recovery time is available.

Q: What inventory considerations should guide part selection?

A: HS1GL RUG has 822 units in stock. Parametric equivalents offer higher availability: HS1GL RVG (18,316 units), ES1GL (95,300 units), and ES1GL RVG (4,619 units). Similar parts S07G-GS08 and S07G-GS18 have significantly higher inventory (658,490 and 95,100 units respectively). Selection should consider both immediate procurement needs and long-term supply chain requirements.
