Substitute Part Grouping Explanation

Substitution of the SS36LHRFG is determined by matching the following critical electrical and mechanical parameters:

Parametric Equivalent Classification: Parts that maintain identical voltage rating (60 V), current rating (3 A), forward voltage characteristics (750 mV @ 3 A), package type (DO-219AB), and mounting configuration (Surface Mount) are classified as parametric equivalents. These parts are direct functional replacements with no derating required.

Similar Classification: Parts that share the same voltage rating (60 V) and package type (DO-219AB) but differ in current rating (1 A or 2 A) are classified as similar. These parts operate within the same voltage envelope and physical footprint but require current derating analysis for application-specific use.

The SS36L RVG represents a parametric equivalent with identical electrical specifications and packaging, differentiated only by tape and reel packaging format. The Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) represent similar alternatives with reduced current ratings and different reverse leakage characteristics.

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

The SS36L RVG is a parametric equivalent to the SS36LHRFG. Both parts share identical electrical specifications (60 V, 3 A, 750 mV forward voltage) and package configuration (DO-219AB surface mount). The primary distinction is packaging format: SS36LHRFG is supplied in bulk, while SS36L RVG is supplied in tape and reel format. Both parts maintain Active product status, ROHS3 compliance, and equivalent thermal operating range (-55°C ~ 150°C). Selection between these two is determined by procurement and assembly requirements rather than electrical performance.

Similar Alternatives (Current Derating Required):

The Vishay parts SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are classified as similar alternatives due to reduced current ratings (1 A and 2 A respectively). These parts maintain the 60 V voltage rating and DO-219AB package compatibility but operate at lower current levels than the SS36LHRFG. Selection of these alternatives requires circuit analysis to confirm that application current demands do not exceed the substitute part's 1 A or 2 A rating.

Compliance Considerations:

The SS1FH6HM3/H and SS2FH6HM3/H carry automotive grade designation and AEC-Q101 qualification, matching the compliance profile of the SS36LHRFG. The SS1FH6-M3/H lacks explicit automotive grade and AEC-Q101 designation, making it unsuitable for applications requiring automotive-qualified components.

Reverse Leakage Differential:

The SS36LHRFG and SS36L RVG specify 500 µA reverse leakage at 60 V, while all Vishay alternatives specify 3 µA at 60 V. Applications sensitive to leakage current characteristics must account for this 167-fold difference when evaluating similar alternatives.

Frequently Asked Questions (FAQ)

Q: Can the SS36L RVG be used as a direct replacement for the SS36LHRFG?

A: Yes. The SS36L RVG is a parametric equivalent with identical electrical specifications (60 V, 3 A, 750 mV forward voltage) and package type (DO-219AB). The only difference is packaging format (tape and reel versus bulk). No circuit modifications or derating are required.

Q: What is the difference between the SS36LHRFG and the Vishay SS1FH6-M3/H?

A: The primary difference is current rating: SS36LHRFG is rated for 3 A while SS1FH6-M3/H is rated for 1 A. Both share the same 60 V voltage rating and DO-219AB package. The SS1FH6-M3/H also lacks automotive grade and AEC-Q101 qualification. Use of SS1FH6-M3/H requires confirmation that circuit current does not exceed 1 A.

Q: Are the Vishay SS2FH6HM3/H and SS1FH6HM3/H suitable for automotive applications?

A: Yes. Both parts carry automotive grade designation and AEC-Q101 qualification, matching the compliance requirements of the SS36LHRFG. However, the SS2FH6HM3/H is limited to 2 A and SS1FH6HM3/H is limited to 1 A, requiring current derating analysis for applications designed for 3 A operation.

Q: What is the significance of the reverse leakage difference between the SS36LHRFG and Vishay alternatives?

A: The SS36LHRFG specifies 500 µA reverse leakage at 60 V, while Vishay alternatives specify 3 µA. This 167-fold difference is material for applications with strict leakage current budgets. Selection of Vishay alternatives provides superior leakage performance but requires confirmation that the lower current rating is acceptable.

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

A: The SS1FH6-M3/H lacks explicit automotive grade designation and AEC-Q101 qualification. Use in automotive applications requires verification that the application does not mandate these qualifications. The part is otherwise electrically compatible with the SS36LHRFG at reduced current levels (1 A maximum).

Q: What packaging considerations apply when selecting between these parts?

A: The SS36LHRFG is supplied in bulk packaging, while SS36L RVG and all Vishay alternatives are supplied in tape and reel format. Tape and reel packaging is standard for automated assembly processes. Bulk packaging may be preferred for manual assembly or low-volume applications. Electrical performance is independent of packaging format.

Q: Is the operating temperature range a factor in part selection?

A: The SS36LHRFG and SS36L RVG specify -55°C ~ 150°C junction temperature range, while all Vishay alternatives specify -55°C ~ 175°C. For applications operating above 150°C, Vishay alternatives provide extended thermal margin. For applications within -55°C ~ 150°C, both part families are equivalent.
