RS1KL RUG Equivalent & Substitute Parts

Part Overview

The RS1KL RUG is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V DC reverse voltage and 800 mA average rectified current. This surface mount component is packaged in Sub SMA (DO-219AB) format and supplied on Tape & Reel (TR). The part is Active status, ROHS3 compliant, and suitable for applications requiring fast recovery characteristics with reverse recovery time of 500 ns or less.

Equivalent and substitute parts are identified to provide design flexibility for procurement, inventory management, and application-specific requirements while maintaining electrical and mechanical compatibility within the rectifier diode category.

Substitute Part Grouping Explanation

Substitute parts for the RS1KL RUG are classified into two categories based on electrical parameter alignment and packaging format:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 800 V reverse voltage, 800 mA average rectified current, 1.3 V forward voltage at 800 mA, 500 ns reverse recovery time, 5 µA reverse leakage current at 800 V, and 10 pF capacitance at 4 V. These parts differ only in packaging format (Cut Tape versus Tape & Reel) and are direct functional replacements.

Similar Parts share the same 800 V reverse voltage rating and DO-219AB package but operate at reduced average rectified current (500 mA instead of 800 mA), lower reverse recovery time (300 ns), lower reverse leakage current (2 µA), and reduced capacitance (4 pF). These parts are manufactured by Vishay General Semiconductor and include automotive-grade qualification (AEC-Q101). Similar parts are suitable for applications where the lower current rating is acceptable and where automotive qualification is required or beneficial.

Key parameters determining substitution eligibility:

Voltage - DC Reverse (Vr) (Max): 800 V
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C
RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

RS1KL and RS1KL RVG are parametric equivalents to RS1KL RUG, maintaining identical electrical characteristics across all specified parameters. Selection between these parts is determined by packaging format requirements:

RS1KL RUG (Tape & Reel): Original specification format
RS1KL (Cut Tape): Suitable for lower-volume applications or manual assembly processes
RS1KL RVG (Tape & Reel): Alternative Tape & Reel source from Taiwan Semiconductor Corporation

All three parts are ROHS3 compliant, Active status, and carry MSL 1 (Unlimited) moisture sensitivity rating.

For Current-Reduced Applications (Similar Parts):

RS07K-GS08 and RS07K-GS18 are suitable substitutes where the application current requirement does not exceed 500 mA average rectified current. These Vishay General Semiconductor parts provide additional benefits:

Automotive-grade qualification (AEC-Q101)
Faster reverse recovery time (300 ns versus 500 ns)
Lower reverse leakage current (2 µA versus 5 µA)
Reduced junction capacitance (4 pF versus 10 pF)

Selection between RS07K-GS08 (Cut Tape & Digi-Reel®) and RS07K-GS18 (Tape & Reel) follows packaging format requirements. Both parts are ROHS3 compliant and Active status.

All substitute parts maintain the same operating temperature range (-55°C to 150°C) and DO-219AB package format, ensuring mechanical and thermal compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can RS1KL (Cut Tape) be used as a direct replacement for RS1KL RUG (Tape & Reel)?

A: Yes. RS1KL in Cut Tape format is a parametric equivalent with identical electrical specifications. The difference is packaging format only. Cut Tape is suitable for applications where Tape & Reel is not required by assembly processes.

Q: What is the primary difference between the Taiwan Semiconductor RS1KL series and the Vishay RS07K-GS series?

A: The RS1KL series is rated for 800 mA average rectified current, while the RS07K-GS series is rated for 500 mA. The Vishay parts also feature faster reverse recovery time (300 ns), lower reverse leakage current (2 µA), and automotive-grade qualification (AEC-Q101). Both maintain 800 V reverse voltage rating and DO-219AB packaging.

Q: Are the Vishay RS07K-GS parts suitable for all applications using RS1KL RUG?

A: RS07K-GS parts are suitable only for applications where the average rectified current requirement does not exceed 500 mA. If the application requires 800 mA current capability, the RS1KL series must be used. Verify application current requirements before substitution.

Q: What does AEC-Q101 qualification mean for the RS07K-GS parts?

A: AEC-Q101 is an automotive-grade qualification standard. RS07K-GS parts meeting this qualification are suitable for automotive applications. This qualification is not present on the Taiwan Semiconductor RS1KL series.

Q: Can I mix packaging formats (Tape & Reel and Cut Tape) in the same production run?

A: Packaging format selection is determined by assembly process requirements. Tape & Reel format is standard for automated pick-and-place assembly. Cut Tape format is used for manual assembly or lower-volume production. Electrical performance is identical; packaging format does not affect circuit functionality.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—RS1KL RUG, RS1KL, RS1KL RVG, RS07K-GS08, and RS07K-GS18—are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across the same junction temperature range: -55°C to 150°C. This ensures thermal compatibility across all substitution options.

Q: How do I determine which substitute part is appropriate for my application?

A: Identify the critical parameters for your application: required average rectified current (800 mA or 500 mA), packaging format preference (Tape & Reel or Cut Tape), and whether automotive qualification is required. Match these requirements to the part specifications in the Parameter Comparison table.
