Substitute Part Grouping Explanation

Substitute parts for the SS13LHRUG are grouped into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Direct Substitution): Parts that maintain identical voltage rating (30 V), current rating (1 A), package type (DO-219AB / Sub SMA), and operating temperature range (-55°C to 125°C). These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and are sourced from the same manufacturer.

Similar Manufacturer Parts (Functional Equivalents): Parts that maintain the 30 V voltage rating and DO-219AB package but may differ in current rating (1 A to 2 A or 1.1 A), forward voltage characteristics, reverse leakage current, or operating temperature range. These parts are sourced from Vishay General Semiconductor - Diodes Division and are qualified to the same automotive standard (AEC-Q101) where applicable.

Key parameters determining substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 30 V
Package / Case: Must be DO-219AB or Sub SMA equivalent
Technology: Schottky rectifier diode
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Current rating: Equal or greater than 1 A for direct substitution

Engineering Selection Recommendations

Direct Substitution (Parametric Equivalent): The SS13L RVG is a direct parametric equivalent to the SS13LHRUG, maintaining identical electrical specifications and operating temperature range. Selection between these parts is determined by packaging format requirements: SS13L RVG is supplied in Cut Tape (CT) format, while SS13LHRUG is supplied in standard format. Both parts are manufactured by Taiwan Semiconductor Corporation and are Active product status.

Automotive-Qualified Alternatives: The SS1FL3HM3/H and SS2FL3HM3/H are Vishay General Semiconductor parts qualified to AEC-Q101 automotive standard, matching the qualification level of the SS13LHRUG. The SS1FL3HM3/H maintains the 1 A current rating with improved forward voltage characteristics (480 mV vs. 500 mV) and extended operating temperature range (-55°C to 150°C). The SS2FL3HM3/H provides 2 A current capacity for applications requiring higher current handling.

General-Purpose Alternatives: The SS1FL3-M3/H and SL03-GS18 provide functional equivalence with improved electrical characteristics. The SS1FL3-M3/H offers lower forward voltage (480 mV) and reduced reverse leakage (200 µA) compared to the main part. The SL03-GS18 provides 1.1 A current rating with superior forward voltage (430 mV) and reverse leakage (130 µA) performance.

All substitute parts maintain ROHS3 compliance, Schottky technology, and DO-219AB package compatibility. Selection should be based on application requirements for current capacity, forward voltage performance, operating temperature range, and automotive qualification status.

Frequently Asked Questions (FAQ)

Q: Can SS13L RVG be used as a direct replacement for SS13LHRUG? A: Yes. The SS13L RVG is a parametric equivalent with identical voltage rating (30 V), current rating (1 A), forward voltage (500 mV @ 1 A), and operating temperature range (-55°C to 125°C). The difference is packaging format: SS13L RVG is supplied in Cut Tape (CT) format.

Q: What is the difference between SS1FL3HM3/H and SS1FL3-M3/H? A: Both parts maintain 30 V voltage rating and 1 A current rating with identical forward voltage (480 mV @ 1 A) and reverse leakage (200 µA @ 30 V). The primary difference is packaging format: SS1FL3HM3/H is supplied in Tape & Reel (TR) with AEC-Q101 automotive qualification, while SS1FL3-M3/H is supplied in Cut Tape (CT) & Digi-Reel® format without automotive qualification designation.

Q: Can I use SS2FL3HM3/H in place of SS13LHRUG? A: The SS2FL3HM3/H maintains the 30 V voltage rating and DO-219AB package but is rated for 2 A current capacity versus 1 A for the SS13LHRUG. This part is suitable for applications requiring higher current handling. Forward voltage is 540 mV @ 2 A. Operating temperature range is -55°C to 150°C with AEC-Q101 qualification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance status, matching the environmental compliance of the SS13LHRUG.

Q: Which substitute part has the lowest forward voltage? A: The SL03-GS18 has the lowest forward voltage at 430 mV @ 1.1 A, compared to 500 mV @ 1 A for the SS13LHRUG. This part also features the lowest reverse leakage current at 130 µA @ 30 V.

Q: What is the operating temperature range difference between SS13LHRUG and Vishay alternatives? A: The SS13LHRUG operates from -55°C to 125°C. Vishay General Semiconductor alternatives (SS1FL3-M3/H, SS1FL3HM3/H, SS2FL3-M3/H, SS2FL3HM3/H) extend the upper temperature limit to 150°C, providing 25°C additional thermal margin.

Q: Is automotive qualification available for all substitute parts? A: No. AEC-Q101 automotive qualification is available for SS1FL3HM3/H, SS2FL3HM3/H, and SS2FL3-M3/H (Vishay parts). The SS13L RVG (Taiwan Semiconductor) does not list automotive qualification. The SL03-GS18 and SS1FL3-M3/H do not list automotive qualification.

Q: Can I substitute a higher current-rated part (2 A) for a 1 A application? A: Yes. The SS2FL3HM3/H and SS2FL3-M3/H are rated for 2 A and maintain the 30 V voltage rating and DO-219AB package. These parts are suitable for 1 A applications and provide additional current capacity margin. Forward voltage at 2 A is 540 mV.
