Substitute Part Grouping Explanation

Substitution of the SS26L MQG is determined by electrical and mechanical parameter compatibility. The primary substitution criteria are:

Parametric Equivalence Requirements:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-219AB
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute Classification:

Parametric Equivalent: SS26L RVG maintains identical electrical specifications and package configuration as the main part, differing only in packaging format (Cut Tape versus standard packaging).

Similar Parts with Parameter Deviations: SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are classified as similar parts. SS1FH6-M3/H and SS1FH6HM3/H operate at 1 A average rectified current, representing a current rating reduction from the 2 A specification. SS2FH6HM3/H maintains the 2 A current rating but exhibits a forward voltage of 780 mV @ 2 A, compared to 700 mV @ 2 A for the main part. All similar parts share the DO-219AB package and 60 V reverse voltage rating.

Engineering Selection Recommendations

SS26L RVG is the direct parametric equivalent to SS26L MQG. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications, reverse voltage rating, current capacity, and operating temperature range. The distinction between these parts is packaging format: SS26L MQG is supplied in standard packaging while SS26L RVG is supplied in Cut Tape format. Selection between these two is determined by procurement and assembly requirements rather than electrical performance.

SS2FH6HM3/H is suitable for applications requiring 2 A current capacity at 60 V reverse voltage. This part is manufactured by Vishay General Semiconductor - Diodes Division and carries AEC-Q101 automotive qualification. The forward voltage specification is 780 mV @ 2 A, compared to 700 mV @ 2 A for the main part, representing an 80 mV increase. The operating temperature range extends to 175°C, exceeding the main part's 150°C maximum. Reverse leakage current is specified at 3 µA @ 60 V, significantly lower than the main part's 400 µA @ 60 V specification.

SS1FH6-M3/H and SS1FH6HM3/H are not suitable as direct substitutes for applications requiring 2 A current capacity. Both parts are rated for 1 A average rectified current. SS1FH6HM3/H carries AEC-Q101 automotive qualification, while SS1FH6-M3/H does not. These parts are applicable only to designs where the current requirement is 1 A or lower.

All substitute parts maintain RoHS3 compliance and active product status. Selection should be based on current capacity requirements, automotive qualification necessity, and acceptable forward voltage characteristics for the specific application.

Frequently Asked Questions (FAQ)

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

A: Yes. SS26L RVG is a parametric equivalent with identical electrical specifications, reverse voltage rating, current capacity, and operating temperature range. The parts differ only in packaging format (Cut Tape versus standard packaging). Selection between them is determined by assembly and procurement requirements.

Q: Is SS2FH6HM3/H a suitable substitute for SS26L MQG?

A: SS2FH6HM3/H maintains the 2 A current rating and 60 V reverse voltage specification required by the main part. However, the forward voltage is specified at 780 mV @ 2 A compared to 700 mV @ 2 A for the main part. The reverse leakage current is 3 µA @ 60 V, significantly lower than the main part's 400 µA @ 60 V. The operating temperature range extends to 175°C. Suitability depends on whether the application can accommodate the higher forward voltage and lower reverse leakage characteristics.

Q: Why are SS1FH6-M3/H and SS1FH6HM3/H listed as similar parts rather than direct substitutes?

A: Both SS1FH6-M3/H and SS1FH6HM3/H are rated for 1 A average rectified current, compared to the 2 A specification of SS26L MQG. These parts are not suitable for applications requiring 2 A current capacity. They are applicable only to designs where the current requirement is 1 A or lower.

Q: What is the difference between SS1FH6-M3/H and SS1FH6HM3/H?

A: Both parts share identical electrical specifications, package configuration, and current rating. SS1FH6HM3/H carries AEC-Q101 automotive qualification, while SS1FH6-M3/H does not. Selection between them depends on automotive qualification requirements.

Q: Are all substitute parts in the same package as SS26L MQG?

A: Yes. All substitute parts use the DO-219AB package with surface mount configuration, matching the main part's mechanical requirements.

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

A: SS26L MQG specifies 400 µA @ 60 V reverse leakage current, while SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H specify 3 µA @ 60 V. The Vishay parts exhibit significantly lower reverse leakage. Applications sensitive to leakage current characteristics should account for this difference in circuit design.

Q: Do all parts meet RoHS3 compliance?

A: Yes. SS26L MQG, SS26L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are all RoHS3 compliant.

Q: Which substitute part has automotive qualification?

A: SS1FH6HM3/H and SS2FH6HM3/H both carry AEC-Q101 automotive qualification. SS26L MQG, SS26L RVG, and SS1FH6-M3/H do not have automotive qualification listed.
