Substitute Part Grouping Explanation

Substitution eligibility for the SS210LHMHG is determined by the following critical parameters: voltage rating (100 V DC reverse), current rating (2 A average rectified), package type (DO-219AB Sub SMA), mounting configuration (surface mount), and technology classification (Schottky). Parts are grouped into two categories:

Parametric Equivalent: Parts with identical electrical specifications across all key parameters, including voltage, current, forward voltage drop, reverse leakage, and recovery speed. These parts are direct functional replacements.

Similar Parts: Parts that share the same voltage and package specifications but differ in current rating (1 A versus 2 A) or reverse leakage characteristics. These parts are suitable for applications where the lower current rating is acceptable within circuit design margins.

Engineering Selection Recommendations

SS210L RVG is a parametric equivalent manufactured by Taiwan Semiconductor Corporation with identical electrical specifications to the SS210LHMHG. Both parts share the same voltage rating, current capacity, forward voltage characteristics, and package configuration. The primary distinction is packaging format (Cut Tape & Digi-Reel versus original specification). This part is suitable for direct substitution in applications where packaging format flexibility is acceptable.

SS2FH10HM3/H is manufactured by Vishay General Semiconductor and provides equivalent 2 A current rating and 100 V voltage specification with AEC-Q101 automotive qualification matching the original part grade. Forward voltage is specified at 860 mV versus 850 mV, representing a 10 mV differential. Operating temperature range extends to 175°C compared to 150°C for the original part. This part is suitable for substitution in automotive-grade applications.

SS2FH10-M3/H is a Vishay equivalent with matching 2 A current and 100 V voltage ratings but without automotive grade designation. This part is suitable for non-automotive applications where the lower temperature range requirement is acceptable.

SS1FH10HM3/H and SS1FH10-M3/H are 1 A rated alternatives suitable only for applications where circuit design permits reduced current capacity. These parts share the 100 V voltage rating and DO-219AB package but are not direct functional replacements for 2 A applications.

Frequently Asked Questions (FAQ)

Q: Can SS210L RVG replace SS210LHMHG in all applications?

A: Yes. SS210L RVG is a parametric equivalent with identical electrical specifications. The difference is packaging format (Cut Tape & Digi-Reel versus the original specification). Both parts meet the same voltage, current, and thermal requirements.

Q: What is the difference between SS2FH10HM3/H and SS2FH10-M3/H?

A: Both parts are manufactured by Vishay with identical electrical specifications (100 V, 2 A, 860 mV forward voltage). The distinction is grade classification: SS2FH10HM3/H carries AEC-Q101 automotive qualification, while SS2FH10-M3/H does not. Select SS2FH10HM3/H for automotive applications requiring grade certification.

Q: Can 1 A rated parts (SS1FH10-M3/H or SS1FH10HM3/H) substitute for the 2 A SS210LHMHG?

A: No. These parts are rated for 1 A average rectified current, which is insufficient for applications designed for 2 A operation. Substitution is only valid if circuit design analysis confirms that 1 A capacity is acceptable.

Q: What is the significance of reverse leakage current differences between parts?

A: The SS210LHMHG specifies 100 µA reverse leakage at 100 V, while Vishay alternatives specify 5 µA. Lower reverse leakage reduces standby power dissipation and heat generation. Both values are within acceptable ranges for Schottky diode technology; selection depends on application power budget requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the original SS210LHMHG specification.

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

A: The SS210LHMHG operates from -55°C to 150°C. Vishay alternatives (SS1FH10 and SS2FH10 series) operate from -55°C to 175°C, providing extended high-temperature capability. This difference is not limiting for substitution unless the application requires operation above 150°C.

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

A: Yes. All listed parts use the DO-219AB (Sub SMA / SMF) surface mount package, ensuring mechanical and thermal compatibility in PCB assembly.
