Substitute Part Grouping Explanation

Substitute parts for the SS13L RTG are grouped into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Direct Replacement): Parts that maintain identical electrical specifications across all critical parameters including reverse voltage (30 V), average rectified current (1 A), forward voltage (500 mV @ 1 A), fast recovery speed (≤ 500ns), and package type (DO-219AB). These parts differ only in packaging format (Cut Tape versus Tape & Reel) and are interchangeable at the component level.

Similar Manufacturer Parts (Functional Equivalents): Parts that share the same reverse voltage rating (30 V) and package (DO-219AB) but vary in one or more of the following parameters: average rectified current (1 A to 2 A or 1.1 A), forward voltage characteristics, reverse leakage current, or operating temperature range. These parts are suitable for applications where the circuit design accommodates the parameter variations.

The substitution logic is based strictly on:

Reverse voltage rating (30 V minimum)
Package compatibility (DO-219AB / Sub SMA)
Average rectified current capacity (≥ 1 A)
Fast recovery speed characteristic (≤ 500ns)
Surface mount mounting type
ROHS3 compliance

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

SS13L RVG is the parametric equivalent to SS13L RTG. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications. The only difference is packaging format: SS13L RTG is supplied in Sub SMA format while SS13L RVG is supplied in Cut Tape (CT) format. Both maintain Active product status and ROHS3 compliance. Selection between these two depends on procurement and assembly requirements rather than electrical performance.

Functional Equivalents with Enhanced Performance:

SS1FL3-M3/H and SS1FL3HM3/H (Vishay) are functionally equivalent at the 1 A current rating with improved forward voltage characteristics (480 mV @ 1 A versus 500 mV @ 1 A) and lower reverse leakage current (200 µA @ 30 V versus 400 µA @ 30 V). Both extend the operating temperature range to -55°C ~ 150°C. SS1FL3HM3/H includes AEC-Q101 automotive qualification. Both are ROHS3 compliant and Active product status.

Functional Equivalents with Increased Current Capacity:

SS2FL3-M3/H and SS2FL3HM3/H (Vishay) are rated for 2 A average rectified current, providing higher current capacity than the 1 A SS13L RTG. These parts maintain the 30 V reverse voltage rating and DO-219AB package. Forward voltage is 540 mV @ 2 A. Reverse leakage is 200 µA @ 30 V. Operating temperature range extends to -55°C ~ 150°C. SS2FL3HM3/H includes AEC-Q101 automotive qualification. Both are ROHS3 compliant and Active product status.

Higher Current Alternative:

SL03-GS18 (Vishay) is rated for 1.1 A average rectified current with superior forward voltage performance (430 mV @ 1.1 A) and significantly lower reverse leakage current (130 µA @ 30 V). This part maintains 30 V reverse voltage rating and DO-219AB package. Operating temperature range is -55°C ~ 125°C, matching the SS13L RTG. ROHS3 compliant and Active product status.

All substitute parts maintain Schottky technology, fast recovery speed characteristic (≤ 500ns), surface mount mounting type, and ROHS3 compliance required for direct substitution consideration.

Frequently Asked Questions (FAQ)

Q: Can SS13L RVG be used as a direct replacement for SS13L RTG?

A: Yes. SS13L RVG is a parametric equivalent with identical electrical specifications. The difference is packaging format: SS13L RTG uses Sub SMA format while SS13L RVG uses Cut Tape (CT) format. Both are manufactured by Taiwan Semiconductor Corporation with the same 30 V reverse voltage, 1 A current rating, and 500 mV forward voltage specification.

Q: What is the difference between the Vishay SS1FL3-M3/H and SS1FL3HM3/H parts?

A: Both parts have identical electrical specifications: 30 V reverse voltage, 1 A current rating, 480 mV forward voltage, and -55°C ~ 150°C operating temperature range. The difference is packaging format: SS1FL3-M3/H is supplied in Cut Tape (CT) & Digi-Reel® format, while SS1FL3HM3/H is supplied in Tape & Reel (TR) format. Additionally, SS1FL3HM3/H includes AEC-Q101 automotive qualification.

Q: Can I use SS2FL3-M3/H (2 A rated) in place of SS13L RTG (1 A rated)?

A: Yes, from an electrical compatibility standpoint. SS2FL3-M3/H maintains the same 30 V reverse voltage rating and DO-219AB package. The 2 A current rating is a higher capacity specification, making it suitable for circuits designed for 1 A operation. However, the forward voltage is 540 mV @ 2 A compared to 500 mV @ 1 A for the SS13L RTG. Circuit design must accommodate this parameter difference.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Reverse voltage rating of 30 V or higher, (2) Average rectified current capacity of 1 A or greater, (3) DO-219AB package type, (4) Surface mount mounting type, (5) Schottky technology, and (6) Fast recovery speed characteristic (≤ 500ns). All substitute parts listed meet these criteria.

Q: Is SL03-GS18 a suitable replacement for SS13L RTG?

A: Yes. SL03-GS18 maintains the 30 V reverse voltage rating, DO-219AB package, and surface mount type. It is rated for 1.1 A average rectified current, exceeding the 1 A requirement. Forward voltage is 430 mV @ 1.1 A, which is superior to the SS13L RTG specification. Reverse leakage current is 130 µA @ 30 V, significantly lower than the 400 µA specification. Operating temperature range matches at -55°C ~ 125°C.

Q: Do all substitute parts have the same RoHS compliance status?

A: Yes. All listed substitute parts, including SS13L RVG, SL03-GS18, SS1FL3-M3/H, SS1FL3HM3/H, SS2FL3-M3/H, and SS2FL3HM3/H, are ROHS3 compliant and maintain Active product status.

Q: What is the significance of AEC-Q101 qualification on SS1FL3HM3/H and SS2FL3HM3/H?

A: AEC-Q101 is an automotive qualification standard. Parts bearing this qualification have undergone additional testing and validation for automotive applications. SS1FL3HM3/H and SS2FL3HM3/H include this qualification, making them suitable for automotive-grade circuit designs. The SS13L RTG does not carry this qualification.

Q: Can I mix packaging formats (Sub SMA, Cut Tape, Tape & Reel) in the same assembly?

A: Packaging format differences do not affect electrical compatibility or circuit performance. The choice of packaging format is determined by assembly process requirements and procurement logistics. Sub SMA, Cut Tape (CT), and Tape & Reel (TR) formats contain the same component with identical electrical specifications; they differ only in how the parts are supplied and handled during manufacturing.
