Substitute Part Grouping Explanation

Substitution logic for the SS210L RFG is based on the following electrical and mechanical criteria:

Parametric Equivalents share identical specifications across all critical parameters: 100V reverse voltage rating, 2A average rectified current, 850 mV forward voltage at 2A, fast recovery speed classification, DO-219AB package, and surface mount configuration. These parts are direct functional replacements with no performance trade-offs.

Similar Substitutes maintain the same reverse voltage (100V), package type (DO-219AB), mounting method (surface mount), and fast recovery speed classification, but differ in average rectified current capacity (1A vs. 2A) or forward voltage characteristics (800 mV @ 1A). These parts are suitable for applications where the lower current rating is acceptable. Additional considerations include reverse leakage current specifications and operating temperature ranges.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal 100V
Package / Case: Must be DO-219AB
Mounting Type: Must be Surface Mount
Speed Classification: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
Technology: Must be Schottky

Current rating (Io) and forward voltage (Vf) may vary within acceptable application limits for similar substitutes.

Engineering Selection Recommendations

SS210L RVG (Taiwan Semiconductor Corporation) is a parametric equivalent to the SS210L RFG. Both parts share identical electrical specifications: 100V reverse voltage, 2A average rectified current, 850 mV forward voltage at 2A, and fast recovery speed classification. The primary difference is packaging format: SS210L RVG is supplied in Cut Tape (CT) & Digi-Reel® configuration versus the main part's standard packaging. Both maintain Active product status, ROHS3 compliance, and MSL 1 rating. This substitute is suitable for direct replacement in applications requiring the same electrical performance and current capacity.

SS2FH10HM3/H (Vishay General Semiconductor - Diodes Division) is a parametric equivalent from an alternative manufacturer. This part matches the 100V reverse voltage and 2A average rectified current specifications of the main part. Forward voltage is 860 mV @ 2A, which is within acceptable tolerance of the 850 mV specification. The part features extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 150°C), lower reverse leakage current (5 µA @ 100V versus 100 µA @ 100V), and automotive-grade qualification (AEC-Q101). This substitute is suitable for applications requiring equivalent current capacity with enhanced thermal performance and automotive reliability standards.

SS1FH10-M3/H and SS1FH10HM3/H (Vishay General Semiconductor - Diodes Division) are similar substitutes with reduced current capacity. Both parts maintain 100V reverse voltage and fast recovery speed classification but are rated for 1A average rectified current versus 2A. Forward voltage is 800 mV @ 1A. These substitutes are applicable only in circuits where the lower current rating satisfies design requirements. SS1FH10HM3/H includes automotive-grade qualification (AEC-Q101) and extended operating temperature range (-55°C ~ 175°C). Both variants feature lower reverse leakage current (5 µA @ 100V) and capacitance specification (70pF @ 4V, 1MHz).

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status. Selection should be based on application current requirements, thermal operating range, and packaging format availability.

Frequently Asked Questions (FAQ)

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

A: Yes. 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 speed classification. The parts differ only in packaging format (Cut Tape & Digi-Reel® versus standard packaging). Both are manufactured by Taiwan Semiconductor Corporation and maintain identical compliance ratings.

Q: What is the difference between the main part and Vishay substitutes?

A: The primary differences are manufacturer and reverse leakage current. Taiwan Semiconductor Corporation parts (SS210L RFG and SS210L RVG) specify 100 µA reverse leakage at 100V. Vishay parts (SS1FH10-M3/H, SS1FH10HM3/H, SS2FH10HM3/H) specify 5 µA reverse leakage at 100V, representing lower leakage performance. Vishay parts also feature extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 150°C) and automotive-grade qualification where applicable.

Q: Can I use SS1FH10-M3/H or SS1FH10HM3/H in place of SS210L RFG?

A: These parts are similar substitutes only if your application current requirement is 1A or less. Both are rated for 1A average rectified current, whereas the main part is rated for 2A. All other electrical parameters (100V reverse voltage, fast recovery speed, DO-219AB package, surface mount configuration) are compatible. If your circuit requires 2A capacity, these 1A-rated parts are not suitable.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates the diode exhibits fast recovery characteristics with recovery time not exceeding 500 nanoseconds when forward current exceeds 200 milliamps. All substitute parts in this list meet this classification, ensuring compatibility in high-frequency switching applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed—SS210L RFG, SS210L RVG, SS1FH10-M3/H, SS1FH10HM3/H, and SS2FH10HM3/H—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All maintain REACH Unaffected status and EAR99 export classification.

Q: What is the significance of AEC-Q101 qualification on Vishay parts?

A: AEC-Q101 is an automotive electronics qualification standard. SS1FH10HM3/H and SS2FH10HM3/H carry this qualification, indicating these parts meet automotive industry reliability and performance requirements. This qualification is relevant only if your application requires automotive-grade components.

Q: Do all parts use the same DO-219AB package?

A: Yes. All substitute parts use the DO-219AB package (Sub SMA / SMF designation). This ensures mechanical and electrical compatibility in surface mount applications. Differences exist only in tape format (Cut Tape & Digi-Reel® versus Tape & Reel) for inventory and handling purposes, not in the component package itself.

Q: What is the difference between forward voltage specifications at different current levels?

A: Forward voltage varies with current. SS210L RFG specifies 850 mV @ 2A. SS1FH10-M3/H and SS1FH10HM3/H specify 800 mV @ 1A (lower current). SS2FH10HM3/H specifies 860 mV @ 2A (same current as main part). These differences reflect manufacturer design variations and are within acceptable tolerance for Schottky diode applications.
