Substitute Categories:

Parametric Equivalent (Full Electrical Match): Parts matching all electrical specifications and current rating of 2A are classified as parametric equivalents. These parts maintain identical voltage and current ratings with compatible forward voltage characteristics.

Similar Parts (Reduced Current Rating): Parts with 1A current rating are classified as similar substitutes. These components share the same 100V voltage rating, package type, and fast recovery characteristics but operate at reduced current capacity. These substitutes are suitable for applications where the full 2A rating is not required.

Manufacturer Variants: Substitute parts from Vishay General Semiconductor - Diodes Division (eSMP® series) maintain electrical compatibility within the specified parameters while offering alternative packaging and availability options.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

SS210L RVG is a direct parametric equivalent to SS210LHM2G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications: 100V reverse voltage, 2A average rectified current, 850mV forward voltage at 2A, and fast recovery characteristics. Both maintain the same operating temperature range (-55 to 150°C) and package configuration (DO-219AB Sub SMA). This part is suitable for direct substitution in all applications where SS210LHM2G is specified.

Automotive-Grade Alternatives (2A Rating):

SS2FH10HM3/H (Vishay General Semiconductor) is an automotive-grade substitute with AEC-Q101 qualification matching the original part's automotive specification. This part maintains 100V voltage rating and 2A current capacity with compatible forward voltage (860mV @ 2A). The extended operating temperature range (-55 to 175°C) provides additional thermal margin. This substitute is appropriate for automotive applications requiring AEC-Q101 compliance.

SS2FH10-M3/H (Vishay General Semiconductor) is a functionally equivalent 2A Schottky diode with 100V rating and fast recovery characteristics. While not carrying automotive-grade designation, it maintains electrical compatibility with the original part. This substitute is suitable for non-automotive applications or where automotive qualification is not a design requirement.

Reduced Current Alternatives (1A Rating):

SS1FH10HM3/H (Vishay General Semiconductor) is an automotive-grade 1A Schottky diode with AEC-Q101 qualification. This part is suitable for applications where the full 2A current capacity is not required and where automotive-grade components are mandated.

SS1FH10-M3/H (Vishay General Semiconductor) is a 1A equivalent without automotive-grade designation, appropriate for non-automotive applications requiring reduced current capacity.

Frequently Asked Questions (FAQ)

Q: Can SS210L RVG be used as a direct replacement for SS210LHM2G?

A: Yes. SS210L RVG is a parametric equivalent with identical electrical specifications, voltage rating (100V), current rating (2A), forward voltage (850mV @ 2A), and package type (DO-219AB Sub SMA). Both parts are manufactured by Taiwan Semiconductor Corporation and maintain the same operating temperature range.

Q: What is the difference between the 2A and 1A substitute options?

A: The primary difference is average rectified current capacity. The 2A variants (SS2FH10HM3/H and SS2FH10-M3/H) maintain the full 2A rating of the original SS210LHM2G. The 1A variants (SS1FH10HM3/H and SS1FH10-M3/H) operate at reduced current capacity. Selection depends on circuit current requirements. If the application requires 2A capability, use 2A-rated parts. If the circuit operates below 1A, either rating is acceptable.

Q: Are all substitute parts compatible with the DO-219AB package footprint?

A: Yes. All listed substitute parts use the DO-219AB (Sub SMA) surface mount package. Footprint compatibility is maintained across all substitutes, allowing direct PCB placement without layout modifications.

Q: Which substitutes carry automotive-grade qualification?

A: SS1FH10HM3/H and SS2FH10HM3/H both carry AEC-Q101 automotive qualification. SS210L RVG (the parametric equivalent) does not explicitly list automotive qualification in the provided specifications. For automotive applications requiring AEC-Q101 compliance, use SS1FH10HM3/H (1A) or SS2FH10HM3/H (2A).

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

A: The original SS210LHM2G specifies 100µA reverse leakage at 100V. Vishay eSMP® series parts (SS1FH10 and SS2FH10 variants) specify 5µA reverse leakage at 100V, representing lower leakage characteristics. This difference does not prevent substitution but indicates improved leakage performance in the Vishay alternatives.

Q: Can SS210L RVG be used in applications where SS210LHM2G is currently specified?

A: Yes. SS210L RVG is a parametric equivalent with matching electrical performance, voltage rating, current rating, and package type. It is suitable for direct substitution in all applications where SS210LHM2G is specified.

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

A: The original SS210LHM2G operates from -55 to 150°C. Vishay substitutes operate from -55 to 175°C, providing an extended upper temperature range of 25°C. This extended range does not prevent substitution and may provide additional thermal margin in high-temperature applications.
