Substitute Part Grouping Explanation

Substitute parts for the SS210L RQG are classified into two categories based on parametric equivalence and similarity:

Parametric Equivalent: Parts that match all critical electrical specifications and thermal operating range, differing only in packaging format or supplier designation.

Similar Parts: Parts that share the same package, voltage rating, and technology but differ in current rating or reverse leakage characteristics. These parts are suitable for applications where the specified current rating is not exceeded.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal 100 V
Package / Case: Must be DO-219AB (Sub SMA)
Technology: Must be Schottky
Mounting Type: Must be Surface Mount
Speed: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
RoHS Status: Must be RoHS3 Compliant

Current rating, forward voltage, and reverse leakage may vary within acceptable design margins for similar parts, provided the application does not exceed the substitute part's rated current.

Engineering Selection Recommendations

SS210L RVG (Parametric Equivalent): This part is a direct parametric equivalent to the SS210L RQG, manufactured by Taiwan Semiconductor Corporation. Both parts share identical electrical specifications, voltage rating, current rating, and thermal operating range. The SS210L RVG differs only in packaging format (Cut Tape & Digi-Reel® versus standard packaging). This part is suitable for direct substitution in all applications where the SS210L RQG is specified. Product status is Active with RoHS3 compliance and REACH unaffected designation.

SS2FH10HM3/H (Parametric Equivalent - Automotive Grade): This part matches the SS210L RQG in voltage rating (100 V), current rating (2 A), package (DO-219AB), and speed characteristics. The SS2FH10HM3/H is manufactured by Vishay General Semiconductor - Diodes Division and carries Automotive grade designation with AEC-Q101 qualification. Forward voltage is 860 mV @ 2 A (compared to 850 mV @ 2 A for the SS210L RQG), which is within acceptable design margins. Reverse leakage is 5 µA @ 100 V (lower than the SS210L RQG at 100 µA @ 100 V). Operating temperature range extends to -55°C ~ 175°C. This part is suitable for substitution in automotive and industrial applications requiring AEC-Q101 qualification.

SS1FH10-M3/H and SS1FH10HM3/H (Similar Parts - Reduced Current Rating): These Vishay parts are rated for 1 A average rectified current, compared to 2 A for the SS210L RQG. Both share the 100 V voltage rating, DO-219AB package, and Schottky technology. The SS1FH10HM3/H carries Automotive grade and AEC-Q101 qualification. These parts are suitable for substitution only in applications where the circuit current does not exceed 1 A. Forward voltage is 800 mV @ 1 A, and reverse leakage is 5 µA @ 100 V. Operating temperature range is -55°C ~ 175°C.

Frequently Asked Questions (FAQ)

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

A: Yes. The SS210L RVG is a parametric equivalent with identical electrical specifications, voltage rating (100 V), current rating (2 A), forward voltage (850 mV @ 2 A), and thermal operating range (-55°C ~ 150°C). Both are manufactured by Taiwan Semiconductor Corporation and are RoHS3 compliant. The parts differ only in packaging format.

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

A: Both parts are rated for 100 V and 2 A with DO-219AB packaging and Schottky technology. The SS2FH10HM3/H is manufactured by Vishay and carries Automotive grade with AEC-Q101 qualification. Forward voltage is 860 mV @ 2 A (versus 850 mV @ 2 A), and reverse leakage is 5 µA @ 100 V (versus 100 µA @ 100 V). Operating temperature extends to 175°C. These differences are within acceptable design margins for most applications.

Q: Can SS1FH10-M3/H or SS1FH10HM3/H replace SS210L RQG?

A: These parts can replace SS210L RQG only in applications where the circuit current does not exceed 1 A. Both are rated for 1 A average rectified current, compared to 2 A for the SS210L RQG. All other electrical parameters (100 V voltage rating, DO-219AB package, Schottky technology, fast recovery speed) are compatible. The SS1FH10HM3/H includes Automotive grade and AEC-Q101 qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (SS210L RVG, SS1FH10-M3/H, SS1FH10HM3/H, and SS2FH10HM3/H) are RoHS3 compliant and REACH unaffected.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the industry standard package designation for Sub SMA surface mount diodes. All parts in this comparison use DO-219AB packaging, ensuring mechanical and electrical compatibility on printed circuit boards. Package compatibility is a primary criterion for substitution eligibility.

Q: Why is reverse leakage lower in Vishay parts compared to Taiwan Semiconductor parts?

A: Reverse leakage characteristics vary based on manufacturing process and design specifications. The Vishay eSMP® series parts (SS1FH10-M3/H, SS1FH10HM3/H, SS2FH10HM3/H) specify 5 µA @ 100 V, while Taiwan Semiconductor parts specify 100 µA @ 100 V. Both values are within acceptable ranges for Schottky diode applications. Lower reverse leakage may provide benefits in low-power or high-impedance circuits.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts carrying this qualification (SS1FH10HM3/H and SS2FH10HM3/H) have undergone additional testing and validation for automotive applications. These parts are suitable for use in automotive and mission-critical industrial applications.

Q: Can I use SS210L RQG in applications requiring Automotive grade components?

A: The SS210L RQG does not carry Automotive grade or AEC-Q101 qualification. For applications requiring Automotive grade components, use SS1FH10HM3/H (1 A rating) or SS2FH10HM3/H (2 A rating) instead.

Q: What is the operating temperature difference between substitute parts?

A: SS210L RQG and SS210L RVG operate from -55°C to 150°C. Vishay parts (SS1FH10-M3/H, SS1FH10HM3/H, SS2FH10HM3/H) operate from -55°C to 175°C, providing a 25°C higher upper temperature limit. This extended range may be beneficial in high-temperature applications.
