Substitute Part Grouping Explanation

Substitution of the SS26L RUG is determined by electrical and mechanical parameter compatibility within the Schottky rectifier diode category. The critical parameters governing substitution are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 60 V minimum requirement
Current - Average Rectified (Io): 2 A minimum requirement for direct equivalence; 1 A parts are suitable for reduced-current applications
Voltage - Forward (Vf) (Max): Acceptable within specified operating conditions
Speed: Fast Recovery characteristic ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: Specified at 60 V

Mechanical Parameters:

Package / Case: DO-219AB (Sub SMA compatible)
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C minimum to 150°C minimum

Substitute parts are grouped into two categories:

Parametric Equivalent: SS26L RVG maintains identical electrical specifications and current rating (2 A) with variation in packaging format only (Cut Tape versus standard packaging).

Similar Parts: SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are classified as similar due to differences in current rating, forward voltage, reverse leakage characteristics, or automotive qualification status. These parts share the same 60 V reverse voltage rating and DO-219AB package but differ in one or more secondary parameters.

Engineering Selection Recommendations

SS26L RVG is the direct parametric equivalent to SS26L RUG. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (60 V, 2 A, 700 mV forward voltage) and operating temperature range (-55°C ~ 150°C). The only distinction is packaging format: SS26L RVG is supplied in Cut Tape (CT) format, while SS26L RUG packaging format is not specified. Both parts maintain ROHS3 compliance and Active product status. Selection between these two parts depends on packaging and supply chain requirements.

SS2FH6HM3/H is a full electrical equivalent to SS26L RUG, matching the 2 A current rating and 60 V reverse voltage specification. This Vishay part is manufactured by Vishay General Semiconductor - Diodes Division and includes AEC-Q101 automotive qualification. The forward voltage specification is 780 mV @ 2 A, compared to 700 mV @ 2 A for the SS26L RUG. The operating temperature range extends to 175°C (versus 150°C for SS26L RUG), and reverse leakage current is significantly lower at 3 µA @ 60 V (versus 400 µA @ 60 V). SS2FH6HM3/H is supplied in Tape & Reel (TR) format and is suitable for applications requiring automotive-grade components.

SS1FH6-M3/H and SS1FH6HM3/H are reduced-current alternatives rated for 1 A average rectified current. These parts are suitable for applications where the 2 A rating of the main part exceeds system requirements. SS1FH6HM3/H includes AEC-Q101 automotive qualification, while SS1FH6-M3/H does not. Both Vishay parts feature lower reverse leakage current (3 µA @ 60 V) and extended operating temperature range (-55°C ~ 175°C) compared to the SS26L RUG.

Selection criteria:

For direct replacement with identical specifications and Taiwan Semiconductor Corporation sourcing: SS26L RVG
For automotive-qualified 2 A equivalent: SS2FH6HM3/H
For reduced-current applications with automotive qualification: SS1FH6HM3/H
For reduced-current applications without automotive requirement: SS1FH6-M3/H

All substitute parts maintain ROHS3 compliance, Active product status, and DO-219AB package compatibility with the SS26L RUG.

Frequently Asked Questions (FAQ)

Q: Can SS26L RVG be used as a direct replacement for SS26L RUG?

A: Yes. SS26L RVG is a parametric equivalent with identical electrical specifications (60 V reverse voltage, 2 A current rating, 700 mV forward voltage) and operating temperature range (-55°C ~ 150°C). The parts differ only in packaging format. Both are manufactured by Taiwan Semiconductor Corporation and are ROHS3 compliant.

Q: What is the difference between SS26L RUG and SS2FH6HM3/H?

A: Both parts are rated for 60 V reverse voltage and 2 A average rectified current in DO-219AB packages. SS2FH6HM3/H is manufactured by Vishay and includes AEC-Q101 automotive qualification. Key differences include: forward voltage of 780 mV @ 2 A (versus 700 mV @ 2 A), reverse leakage current of 3 µA @ 60 V (versus 400 µA @ 60 V), and extended operating temperature range to 175°C (versus 150°C). SS2FH6HM3/H is supplied in Tape & Reel format.

Q: Can I use SS1FH6-M3/H or SS1FH6HM3/H to replace SS26L RUG?

A: These parts are suitable for applications where the average rectified current requirement is 1 A or less. Both are rated for 60 V reverse voltage and use the same DO-219AB package. They feature lower reverse leakage current (3 µA @ 60 V) and extended operating temperature range (-55°C ~ 175°C). SS1FH6HM3/H includes AEC-Q101 automotive qualification. Direct substitution is not recommended if the application requires 2 A current capacity.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive qualification standard. Parts bearing this qualification (SS1FH6HM3/H and SS2FH6HM3/H) have been tested and approved for automotive applications. This qualification is not specified for SS26L RUG or SS26L RVG.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SS26L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are all ROHS3 compliant, matching the compliance status of SS26L RUG.

Q: What is the significance of the reverse leakage current difference between SS26L RUG and Vishay alternatives?

A: SS26L RUG specifies 400 µA @ 60 V reverse leakage current, while Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify 3 µA @ 60 V. Lower reverse leakage current reduces power dissipation and heat generation in reverse-biased conditions. Applications sensitive to leakage current may benefit from Vishay alternatives.

Q: Do all substitute parts use the same package?

A: Yes. All substitute parts use the DO-219AB package (Sub SMA / SMF), which is mechanically and electrically compatible with SS26L RUG. Packaging format (Cut Tape, Tape & Reel) differs but does not affect component functionality or PCB mounting.

Q: What is the operating temperature range difference?

A: SS26L RUG and SS26L RVG are rated for -55°C ~ 150°C junction temperature. Vishay alternatives (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) are rated for -55°C ~ 175°C. Applications requiring operation above 150°C require Vishay parts.
