Substitute Part Grouping Explanation

Substitute parts for the SS210L RHG are classified into two categories based on electrical parameter alignment and packaging availability:

Parametric Equivalent (Direct Substitution): The SS210L RVG maintains identical electrical specifications to the main part: 100V reverse voltage, 2A average rectified current, 850 mV forward voltage at 2A, and fast recovery characteristics. The only difference is packaging format (Cut Tape & Digi-Reel® versus standard packaging). This part is a direct functional equivalent.

Similar Parts (Current-Reduced Alternatives): The SS1FH10-M3/H, SS1FH10HM3/H, and SS2FH10HM3/H are classified as similar parts due to variations in average rectified current rating or manufacturer origin. The SS1FH10 series components are rated at 1A (versus 2A for the main part), while the SS2FH10HM3/H maintains the 2A rating. All similar parts share the 100V reverse voltage specification, DO-219AB package, fast recovery speed classification, and surface mount mounting type. The SS2FH10HM3/H and SS1FH10HM3/H include automotive-grade qualification (AEC-Q101) and extended junction temperature range (-55°C to 175°C).

Substitution eligibility is determined by:

Voltage - DC Reverse (Vr) Maximum: 100V (required match)
Package / Case: DO-219AB (required match)
Mounting Type: Surface Mount (required match)
Technology: Schottky (required match)
Current - Average Rectified (Io): 2A for direct equivalents; 1A for reduced-current alternatives
Speed Classification: Fast Recovery ≤ 500ns (required match)

Engineering Selection Recommendations

SS210L RVG (Parametric Equivalent): The SS210L RVG is the direct parametric equivalent to the SS210L RHG, offering identical electrical performance across all critical specifications including 100V reverse voltage, 2A average rectified current, and 850 mV forward voltage at 2A. Both parts maintain Active product status, RoHS3 compliance, and MSL Level 1 rating. Selection of the SS210L RVG is appropriate when packaging format (Cut Tape & Digi-Reel®) aligns with procurement and assembly requirements.

SS2FH10HM3/H (Similar - 2A Rated, Automotive Grade): The SS2FH10HM3/H maintains the 2A current rating and 100V reverse voltage specification of the main part while offering extended junction temperature range (-55°C to 175°C) and automotive-grade qualification (AEC-Q101). Forward voltage is 860 mV at 2A, within acceptable tolerance of the main part's 850 mV specification. This part is suitable for applications requiring automotive-grade components or extended temperature operation. All compliance certifications (RoHS3, REACH Unaffected) are maintained.

SS1FH10-M3/H and SS1FH10HM3/H (Similar - 1A Rated): The SS1FH10 series components are rated at 1A average rectified current, representing a reduction from the main part's 2A specification. These parts are suitable only for applications where the circuit design accommodates the lower current rating. The SS1FH10HM3/H includes automotive-grade qualification (AEC-Q101) and extended temperature range. Both maintain 100V reverse voltage, DO-219AB package compatibility, and RoHS3 compliance. Reverse leakage current is reduced to 5 µA at 100V compared to the main part's 100 µA specification.

All substitute parts maintain Active product status and full regulatory compliance (RoHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

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

A: Yes. The SS210L RVG is a parametric equivalent with identical electrical specifications: 100V reverse voltage, 2A average rectified current, 850 mV forward voltage at 2A, and fast recovery characteristics. The difference is packaging format. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical compliance status.

Q: What is the primary difference between the SS210L RHG and the SS2FH10HM3/H?

A: Both parts share the same 100V reverse voltage, 2A average rectified current rating, and DO-219AB package. The SS2FH10HM3/H is manufactured by Vishay General Semiconductor and includes automotive-grade qualification (AEC-Q101) with extended junction temperature range (-55°C to 175°C versus -55°C to 150°C). Forward voltage is 860 mV at 2A compared to 850 mV for the main part. Reverse leakage current is lower at 5 µA versus 100 µA.

Q: Can the SS1FH10-M3/H or SS1FH10HM3/H replace the SS210L RHG in all applications?

A: No. The SS1FH10 series components are rated at 1A average rectified current, compared to the main part's 2A rating. These parts are suitable only for circuits designed to operate at or below 1A. All other electrical parameters (100V reverse voltage, fast recovery speed, DO-219AB package) are compatible.

Q: What is the difference between SS1FH10-M3/H and SS1FH10HM3/H?

A: Both parts are electrically identical with 100V reverse voltage and 1A average rectified current. The SS1FH10HM3/H includes automotive-grade qualification (AEC-Q101) and is supplied in Cut Tape & Digi-Reel® packaging, while the SS1FH10-M3/H is supplied in Tape & Reel format. The SS1FH10HM3/H is suitable for automotive applications requiring AEC-Q101 certification.

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

A: Yes. All substitute parts listed use the DO-219AB (Sub SMA / SMF) package and are surface mount components. PCB footprint compatibility is maintained across all parts.

Q: What is the reverse leakage current difference between the main part and Vishay substitute parts?

A: The SS210L RHG specifies 100 µA reverse leakage current at 100V. The Vishay parts (SS1FH10-M3/H, SS1FH10HM3/H, and SS2FH10HM3/H) specify 5 µA reverse leakage current at 100V. This represents lower leakage in the Vishay components, which may be advantageous in low-power or high-impedance circuit applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the compliance status of the main part SS210L RHG.

Q: What is the temperature operating range difference?

A: The SS210L RHG and SS210L RVG operate from -55°C to 150°C junction temperature. The Vishay substitute parts (SS1FH10-M3/H, SS1FH10HM3/H, and SS2FH10HM3/H) operate from -55°C to 175°C, providing an extended upper temperature limit of 25°C.
