SS210L RUG Equivalent & Substitute Parts

Part Overview

The SS210L RUG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 2 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified based on matching or compatible electrical ratings, package specifications, and thermal operating ranges. Alternative part numbers may be required due to inventory availability, packaging format preferences, or application-specific compliance requirements such as automotive qualification.

Substitute Part Grouping Explanation

Substitution of the SS210L RUG is determined by the following critical parameters: reverse voltage rating (100 V), average rectified current capacity (2 A), package type (DO-219AB Sub SMA), mounting configuration (surface mount), and operating temperature range (-55°C to 150°C minimum). Parts are grouped into two categories:

Parametric Equivalent (Direct Substitution): Parts with identical electrical ratings and package specifications, differing only in packaging format (tape & reel versus cut tape).

Similar Parts (Functional Substitution with Derating): Parts with the same reverse voltage and package but reduced current ratings (1 A instead of 2 A) or enhanced temperature ranges and automotive qualifications. These require circuit-level evaluation to confirm current capacity is sufficient for the application.

Engineering Selection Recommendations

SS210L RVG (Parametric Equivalent): This part is a direct electrical and mechanical equivalent to the SS210L RUG, differing only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Both parts are manufactured by Taiwan Semiconductor Corporation, carry identical electrical specifications, and maintain ROHS3 compliance. Selection between these two is based solely on procurement and assembly process requirements.

SS2FH10HM3/H (Functional Equivalent with Enhanced Specifications): This Vishay part matches the 2 A current rating and 100 V reverse voltage of the main part. It offers an extended operating temperature range (-55°C to 175°C versus -150°C), lower reverse leakage current (5 µA versus 100 µA), and automotive-grade qualification (AEC-Q101). Forward voltage is marginally higher (860 mV @ 2 A versus 850 mV @ 2 A). This part is suitable for applications requiring automotive compliance or enhanced thermal performance.

SS1FH10-M3/H and SS1FH10HM3/H (Reduced Current Rating Alternatives): These Vishay parts are rated for 1 A average rectified current, representing a 50% reduction from the main part specification. Both maintain the 100 V reverse voltage rating and DO-219AB package. The SS1FH10HM3/H variant includes automotive qualification (AEC-Q101) and an extended temperature range. These parts are applicable only in circuits where the maximum current requirement does not exceed 1 A.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical ratings (100 V, 2 A), package type (DO-219AB), and operating temperature range (-55°C to 150°C). The only difference is packaging format: SS210L RUG is supplied in Tape & Reel format, while SS210L RVG is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility.

Q: What is the difference between the Taiwan Semiconductor and Vishay parts?

A: Taiwan Semiconductor parts (SS210L RUG and SS210L RVG) are identical in electrical performance. Vishay parts (SS1FH10 and SS2FH10 series) offer lower reverse leakage current (5 µA versus 100 µA), extended temperature range to 175°C, and automotive-grade qualification options. The SS2FH10HM3/H maintains the 2 A rating while the SS1FH10 variants are rated for 1 A.

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

A: These parts are suitable only if the circuit design allows operation at 1 A maximum current. Both parts maintain the 100 V reverse voltage rating and DO-219AB package compatibility. The reduced current capacity must be verified against circuit requirements before substitution.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive industry standard qualification for discrete semiconductors. Parts carrying this qualification (SS1FH10HM3/H and SS2FH10HM3/H) have undergone additional reliability testing and are approved for automotive applications. This qualification is not present on the main part or the Taiwan Semiconductor alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—SS210L RUG, SS210L RVG, SS1FH10-M3/H, SS1FH10HM3/H, and SS2FH10HM3/H—carry ROHS3 compliance status and are REACH unaffected.

Q: What is the significance of the reverse leakage current difference?

A: The main part (SS210L RUG) specifies 100 µA reverse leakage at 100 V, while Vishay alternatives specify 5 µA. Lower reverse leakage reduces power dissipation in reverse bias conditions and improves circuit efficiency. This parameter becomes significant in precision analog circuits or low-power applications.

Q: Can packaging format affect circuit performance?

A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) does not affect electrical performance. Format selection is determined by assembly process requirements, equipment compatibility, and inventory management practices. Electrical and thermal characteristics remain identical between SS210L RUG and SS210L RVG.
