Substitute Part Grouping Explanation

Substitute parts for the SS26LHRUG are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalent: Parts that match all critical electrical specifications including reverse voltage (60 V), average rectified current (2 A), forward voltage (700 mV @ 2 A), fast recovery speed (≤ 500ns), and package type (DO-219AB Sub SMA). These parts differ only in packaging format (Cut Tape versus Tape & Reel).

Similar Parts: Parts that maintain the same reverse voltage (60 V), package type (DO-219AB), fast recovery speed (≤ 500ns), and mounting type (Surface Mount), but operate at reduced average rectified current (1 A) or with different forward voltage specifications (780 mV @ 2 A). These parts are suitable for applications where current requirements are lower or where forward voltage tolerance permits the variation.

The substitution logic is based strictly on the following parameters:

Voltage - DC Reverse (Vr) (Max): 60 V
Package / Case: DO-219AB
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Average Rectified (Io): 2 A (for parametric equivalents) or 1 A (for similar parts)
Voltage - Forward (Vf) (Max) @ If: 700 mV @ 2 A (for parametric equivalents) or 700 mV @ 1 A / 780 mV @ 2 A (for similar parts)

Engineering Selection Recommendations

SS26L RVG is the primary parametric equivalent for SS26LHRUG. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications: 60 V reverse voltage, 2 A average rectified current, 700 mV forward voltage at 2 A, and fast recovery speed. The only difference is packaging format (Cut Tape versus Tape & Reel). This part is suitable for direct substitution where packaging format compatibility with assembly processes is confirmed.

SS1FH6HM3/H is a similar part manufactured by Vishay General Semiconductor - Diodes Division. It maintains the same 60 V reverse voltage, DO-219AB package, and fast recovery speed as the main part. However, it is rated for 1 A average rectified current instead of 2 A. This part carries AEC-Q101 automotive qualification matching the main part. Selection of this part is appropriate for applications where the circuit design permits operation at 1 A current levels.

SS2FH6HM3/H is a similar part manufactured by Vishay General Semiconductor - Diodes Division. It matches the main part in 60 V reverse voltage, 2 A average rectified current, and DO-219AB package. The forward voltage specification is 780 mV @ 2 A, which differs from the main part's 700 mV @ 2 A. This part carries AEC-Q101 automotive qualification and operates across an extended temperature range (-55°C ~ 175°C). Selection of this part is appropriate where the 80 mV forward voltage increase is within circuit design tolerance.

SS1FH6-M3/H is a similar part manufactured by Vishay General Semiconductor - Diodes Division. It is rated for 1 A average rectified current and 700 mV forward voltage at 1 A. This part does not carry automotive grade or AEC-Q101 qualification. Selection of this part is appropriate for non-automotive applications where 1 A current rating is sufficient.

All substitute parts maintain ROHS3 compliance and Schottky technology classification. Parts with AEC-Q101 qualification (SS1FH6HM3/H and SS2FH6HM3/H) are suitable for automotive applications requiring formal qualification documentation.

Frequently Asked Questions (FAQ)

Q: Can SS26L RVG be used as a direct replacement for SS26LHRUG?

A: Yes. SS26L RVG is a parametric equivalent with identical electrical specifications: 60 V reverse voltage, 2 A average rectified current, 700 mV forward voltage at 2 A, and fast recovery speed. The parts differ only in packaging format (Cut Tape versus Tape & Reel). Substitution is valid provided the assembly process accommodates the different packaging format.

Q: What is the difference between SS26LHRUG and SS2FH6HM3/H?

A: Both parts are rated for 60 V reverse voltage and 2 A average rectified current in DO-219AB packages. The primary difference is forward voltage: SS26LHRUG specifies 700 mV @ 2 A, while SS2FH6HM3/H specifies 780 mV @ 2 A. SS2FH6HM3/H also offers an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 150°C) and carries AEC-Q101 automotive qualification. Substitution is valid where the 80 mV forward voltage increase is within circuit design tolerance.

Q: Can SS1FH6HM3/H replace SS26LHRUG in all applications?

A: SS1FH6HM3/H is rated for 1 A average rectified current, compared to SS26LHRUG's 2 A rating. Substitution is valid only in applications where the circuit design operates at 1 A or lower current levels. Both parts share 60 V reverse voltage, DO-219AB package, and AEC-Q101 automotive qualification. Forward voltage specifications are identical at 700 mV for their respective current ratings.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the package type for all listed parts. This designation indicates a surface mount Sub SMA (SMF) package format. All substitute parts are mechanically and electrically compatible with this package specification, ensuring compatibility with printed circuit board layouts and assembly equipment designed for DO-219AB components.

Q: Are all substitute parts suitable for automotive applications?

A: SS26LHRUG, SS1FH6HM3/H, and SS2FH6HM3/H carry AEC-Q101 automotive qualification and Automotive grade designation. SS26L RVG does not specify automotive grade or AEC-Q101 qualification in the provided data. SS1FH6-M3/H does not carry automotive qualification. For automotive applications requiring formal qualification documentation, use only parts with explicit AEC-Q101 qualification.

Q: What is the difference in reverse leakage current between the main part and Vishay substitutes?

A: SS26LHRUG specifies 400 µA @ 60 V reverse leakage current. All Vishay substitute parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify 3 µA @ 60 V. The Vishay parts exhibit significantly lower reverse leakage current. This difference may be relevant in applications sensitive to leakage current performance.

Q: Can SS1FH6-M3/H be used in automotive applications?

A: SS1FH6-M3/H does not carry AEC-Q101 automotive qualification or Automotive grade designation. This part is suitable for non-automotive applications. For automotive applications requiring formal qualification, use SS1FH6HM3/H or SS2FH6HM3/H instead.

Q: What is the operating temperature range difference between the main part and substitutes?

A: SS26LHRUG operates from -55°C to 150°C junction temperature. All Vishay substitute parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) operate from -55°C to 175°C. The Vishay parts offer a 25°C higher maximum operating temperature. This extended range may be beneficial in high-temperature applications.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates that all parts in this comparison exhibit fast recovery time characteristics of 500 nanoseconds or less when switching currents greater than 200 mA. This parameter is consistent across all listed parts and is relevant for high-frequency switching applications.
