Substitute Part Grouping Explanation

Substitute parts for the SS26L M2G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Direct Substitution): Parts that maintain identical electrical specifications across all critical parameters: 60 V reverse voltage, 2 A average rectified current, 700 mV forward voltage drop at rated current, fast recovery switching speed, DO-219AB package, and -55°C to 150°C junction temperature range. Packaging format may differ (Cut Tape versus Reel configuration).

Similar Parts (Functional Substitution with Parameter Variance): Parts that share the same 60 V reverse voltage rating and DO-219AB package but differ in one or more of the following parameters: average rectified current (1 A versus 2 A), forward voltage drop (700 mV versus 780 mV at rated current), reverse leakage current (3 µA versus 400 µA), junction temperature range (-55°C to 175°C versus -55°C to 150°C), or automotive qualification status (AEC-Q101).

All substitute parts maintain Schottky technology, fast recovery switching characteristics, RoHS3 compliance, and MSL 1 classification.

Engineering Selection Recommendations

SS26L RVG is the direct parametric equivalent to SS26L M2G. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications. Selection between these two is determined by packaging format requirements: SS26L M2G is supplied in Sub SMA format, while SS26L RVG is supplied in Cut Tape format. Both are active products with RoHS3 compliance and MSL 1 classification.

SS1FH6-M3/H and SS1FH6HM3/H are functionally similar parts with reduced current rating (1 A versus 2 A). These parts are suitable for applications where the 2 A current requirement of the main part exceeds circuit demands. Both are manufactured by Vishay General Semiconductor with improved reverse leakage characteristics (3 µA versus 400 µA) and extended junction temperature range (-55°C to 175°C). SS1FH6HM3/H carries automotive qualification (AEC-Q101), while SS1FH6-M3/H does not.

SS2FH6HM3/H maintains the 2 A current rating of the main part and is manufactured by Vishay General Semiconductor. This part is suitable for applications requiring automotive qualification (AEC-Q101) and extended junction temperature range. Forward voltage drop is specified at 780 mV @ 2 A, representing a 80 mV increase compared to the main part. Reverse leakage is reduced to 3 µA. All substitute parts maintain the DO-219AB package and fast recovery switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can SS26L RVG be used as a direct replacement for SS26L M2G?

A: Yes. SS26L RVG is a parametric equivalent with identical electrical specifications. The only difference is packaging format: SS26L M2G uses Sub SMA format while SS26L RVG uses Cut Tape format. Both are manufactured by Taiwan Semiconductor Corporation and carry identical compliance certifications.

Q: What is the primary difference between the Taiwan Semiconductor Corporation parts and Vishay parts?

A: The Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) feature significantly lower reverse leakage current (3 µA versus 400 µA) and extended junction temperature range (-55°C to 175°C versus -55°C to 150°C). SS1FH6HM3/H and SS2FH6HM3/H include automotive qualification (AEC-Q101).

Q: Can I use SS1FH6-M3/H or SS1FH6HM3/H in place of SS26L M2G?

A: These parts are functionally similar but rated for 1 A average rectified current instead of 2 A. They are suitable only for applications where circuit current requirements do not exceed 1 A. Both maintain 60 V reverse voltage rating and DO-219AB package compatibility.

Q: What is the significance of the 80 mV forward voltage difference in SS2FH6HM3/H?

A: SS2FH6HM3/H specifies 780 mV forward voltage drop at 2 A compared to 700 mV for SS26L M2G. This 80 mV difference represents approximately 11% higher voltage drop and will result in proportionally higher power dissipation in the diode. Circuit thermal design must account for this difference.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity classification, matching the main part specifications.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics qualification standard. SS1FH6HM3/H and SS2FH6HM3/H carry this qualification, indicating suitability for automotive applications. SS26L M2G, SS26L RVG, and SS1FH6-M3/H do not carry this qualification.

Q: Can I substitute based on package type alone?

A: No. Package type (DO-219AB) is necessary but not sufficient for substitution. Electrical parameters including voltage rating, current rating, forward voltage drop, and reverse leakage must be evaluated for circuit compatibility. Packaging format (Sub SMA, Cut Tape, Tape & Reel) affects procurement and assembly processes but does not determine electrical substitutability.
