Substitute Part Grouping Explanation

Substitution of the SS26L R3G is determined by the following critical parameters:

Electrical Compatibility Requirements:

Voltage - DC Reverse (Vr) (Max): 60 V minimum
Current - Average Rectified (Io): 2 A minimum
Voltage - Forward (Vf) (Max) @ If: Must not exceed application requirements
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Physical & Thermal Compatibility Requirements:

Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature - Junction: Must encompass application operating range

Compliance Requirements:

Technology: Schottky
RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and thermal specifications) and similar parts (matching voltage and package but with different current ratings or thermal characteristics).

Engineering Selection Recommendations

Parametric Equivalent:

SS26L RVG is a direct parametric equivalent to SS26L R3G. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (60 V, 2 A, 700 mV forward voltage), matching thermal operating range (-55°C ~ 150°C), and identical package configuration (DO-219AB Sub SMA). The only difference is packaging format (Cut Tape versus standard packaging). This part is suitable for direct substitution without circuit redesign.

Similar Parts with Current Rating Limitations:

SS1FH6-M3/H and SS1FH6HM3/H are Vishay General Semiconductor products rated for 1 A average rectified current, compared to the 2 A rating of the SS26L R3G. These parts share the 60 V voltage rating, DO-219AB package, and Fast Recovery speed characteristics. However, the reduced current rating limits their application to circuits requiring maximum 1 A operation. SS1FH6HM3/H includes AEC-Q101 automotive qualification, extending the operating temperature range to -55°C ~ 175°C.

Similar Part with Matching Current Rating:

SS2FH6HM3/H is a Vishay General Semiconductor product rated for 2 A average rectified current, matching the SS26L R3G current specification. This part maintains the 60 V voltage rating and DO-219AB package compatibility. The forward voltage is specified at 780 mV @ 2 A, compared to 700 mV @ 2 A for the SS26L R3G. SS2FH6HM3/H includes AEC-Q101 automotive qualification and extends the operating temperature range to -55°C ~ 175°C. All parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can SS26L RVG be used as a direct replacement for SS26L R3G?

A: Yes. SS26L RVG is a parametric equivalent with identical electrical specifications, thermal operating range, and package configuration. The difference is packaging format only (Cut Tape versus standard packaging).

Q: What is the primary limitation of SS1FH6-M3/H and SS1FH6HM3/H as substitutes?

A: Both parts are rated for 1 A average rectified current, compared to the 2 A rating of SS26L R3G. These parts are suitable only for applications requiring maximum 1 A operation. They cannot be used in circuits designed for 2 A operation.

Q: Can SS2FH6HM3/H replace SS26L R3G in all applications?

A: SS2FH6HM3/H matches the 2 A current rating and 60 V voltage specification of SS26L R3G. The forward voltage specification differs (780 mV @ 2 A versus 700 mV @ 2 A). This 80 mV difference must be evaluated against circuit design margins. SS2FH6HM3/H provides extended operating temperature range (-55°C ~ 175°C) and AEC-Q101 automotive qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (SS26L RVG, SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H) are ROHS3 compliant and maintain Active product status.

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

A: Both parts are rated for 1 A average rectified current with identical electrical specifications. SS1FH6HM3/H includes AEC-Q101 automotive qualification and extends the operating temperature range to -55°C ~ 175°C, compared to the standard -55°C ~ 175°C range. Both are packaged in DO-219AB (SMF) format.

Q: Does the reverse leakage current difference affect substitution?

A: SS26L R3G specifies 400 µA @ 60 V reverse leakage, while Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify 3 µA @ 60 V. The lower leakage in Vishay parts represents improved performance characteristics. This difference must be evaluated against circuit design requirements for leakage-sensitive applications.

Q: Can these parts be used interchangeably in automated assembly?

A: All substitute parts use the same DO-219AB package and Surface Mount mounting type. Packaging format differences (Cut Tape, Tape & Reel) affect supply chain handling but not circuit compatibility. Verify tape specifications with assembly equipment requirements.
