SS110L RVG Equivalent & Substitute Parts

Part Overview

The SS110L RVG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package (DO-219AB). This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part becomes unavailable, when design requirements demand enhanced specifications such as higher current ratings or improved thermal performance, or when automotive-grade qualification is required for specific applications. The SS110L RVG maintains parametric equivalence with several alternative Schottky diode options from both Taiwan Semiconductor Corporation and Vishay General Semiconductor - Diodes Division.

Substitute Part Grouping Explanation

Substitute parts for the SS110L RVG are classified into two categories based on parametric equivalence and functional compatibility:

Parametric Equivalent (Direct Substitutes): Parts that maintain identical electrical specifications for voltage rating (100 V), current rating (1 A), forward voltage drop (800 mV @ 1 A), and fast recovery speed (≤ 500ns). These parts are interchangeable in applications where the primary part is unavailable. The SS110L from Taiwan Semiconductor Corporation is a parametric equivalent with identical specifications but carries a "Not For New Designs" product status.

Similar Manufacturer Parts (Functional Equivalents): Parts that share the same voltage rating (100 V), package type (DO-219AB), mounting configuration (Surface Mount), and fast recovery speed characteristic, but may differ in current rating, reverse leakage current, capacitance, operating temperature range, or manufacturer. These parts are suitable for applications where the primary part specifications can accommodate the alternative part's characteristics.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 100 V (required match)
Package / Case: DO-219AB (required match)
Mounting Type: Surface Mount (required match)
Technology: Schottky (required match)
Speed: Fast Recovery ≤ 500ns (required match)

Engineering Selection Recommendations

For Direct Parametric Equivalence (1 A Rating):

The SS1FH10-M3/H and SS1FH10HM3/H from Vishay General Semiconductor - Diodes Division are functionally equivalent to the SS110L RVG with identical voltage, current, and forward voltage specifications. Both parts are Active product status. The SS1FH10HM3/H carries AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade components. The Vishay parts demonstrate lower reverse leakage current (5 µA versus 50 µA) and extended operating temperature range (-55 to 175 °C versus -55 to 150 °C), providing enhanced performance margins in thermal-sensitive applications.

For Higher Current Applications (2 A Rating):

The SS2FH10-M3/H and SS2FH10HM3/H from Vishay General Semiconductor - Diodes Division provide doubled current capacity (2 A) while maintaining the 100 V voltage rating and DO-219AB package. These parts are suitable for applications where the primary part's 1 A rating is insufficient. The SS2FH10HM3/H includes AEC-Q101 automotive qualification. Both 2 A variants maintain Active product status and ROHS3 compliance.

For Legacy Design Continuation:

The SS110L from Taiwan Semiconductor Corporation is a parametric equivalent but carries "Not For New Designs" status. This part is suitable only for continuation of existing production runs or legacy system support where design changes are not feasible.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity level, and REACH Unaffected status, ensuring regulatory compatibility with the primary part across all applications.

Frequently Asked Questions (FAQ)

Q: Can the SS1FH10-M3/H directly replace the SS110L RVG in existing designs?

A: Yes. The SS1FH10-M3/H maintains identical voltage rating (100 V), current rating (1 A), forward voltage drop (800 mV @ 1 A), and fast recovery speed (≤ 500ns). Both parts use the DO-219AB package and surface mount configuration. The Vishay part is Active product status and ROHS3 compliant. The primary differences are lower reverse leakage current (5 µA versus 50 µA) and extended operating temperature range (-55 to 175 °C versus -55 to 150 °C), which provide improved performance characteristics.

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

A: Both parts are electrically identical with 100 V rating and 1 A current capacity. The SS1FH10HM3/H includes AEC-Q101 automotive qualification and is available in Tape & Reel (TR) packaging, while the SS1FH10-M3/H is available in Cut Tape (CT) & Digi-Reel® packaging. The SS1FH10HM3/H is suitable for automotive applications requiring formal qualification documentation.

Q: Can I use the SS2FH10-M3/H or SS2FH10HM3/H as substitutes for the SS110L RVG?

A: These parts are functionally compatible but not direct equivalents. The SS2FH10 series provides 2 A current capacity versus the 1 A rating of the SS110L RVG. Both maintain the 100 V voltage rating and DO-219AB package. The 2 A variants are suitable for applications where higher current capacity is required or beneficial. Forward voltage drop increases to 860 mV @ 2 A. The SS2FH10HM3/H includes AEC-Q101 automotive qualification.

Q: What is the significance of the reverse leakage current difference between the SS110L RVG (50 µA) and Vishay alternatives (5 µA)?

A: The Vishay parts demonstrate lower reverse leakage current, indicating reduced parasitic current flow in reverse bias conditions. This characteristic improves efficiency in applications sensitive to leakage current, such as precision rectification circuits or low-power standby applications. The lower leakage does not affect direct substitution compatibility but provides enhanced performance margins.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—SS110L, SS1FH10-M3/H, SS1FH10HM3/H, SS2FH10-M3/H, and SS2FH10HM3/H—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status, ensuring regulatory compatibility across all applications.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications requiring formal qualification, select either SS1FH10HM3/H (1 A rating) or SS2FH10HM3/H (2 A rating), both carrying AEC-Q101 automotive qualification. These parts maintain identical voltage and package specifications while providing documented automotive-grade performance validation.

Q: What is the operating temperature range difference, and does it affect substitution?

A: The SS110L RVG operates from -55 to 150 °C, while Vishay alternatives operate from -55 to 175 °C. The extended upper temperature limit in Vishay parts provides additional thermal margin in high-temperature applications. For applications operating within the -55 to 150 °C range, both part families are compatible. For applications exceeding 150 °C junction temperature, Vishay parts are required.

Q: Can I substitute the SS110L RVG with the SS110L from Taiwan Semiconductor Corporation?

A: Electrical substitution is possible as both parts are parametrically identical. However, the SS110L carries "Not For New Designs" product status, indicating it is intended for legacy production continuation only. For new designs, select Active status alternatives such as the Vishay SS1FH10-M3/H or SS1FH10HM3/H.
