SS110L RUG Equivalent & Substitute Parts

Part Overview

The SS110L RUG 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, or when alternative manufacturers' components offer superior performance characteristics within the same electrical and mechanical parameters. The SS110L RUG can be replaced with parametrically equivalent or higher-rated alternatives that maintain compatibility with the DO-219AB package footprint and core electrical specifications.

Substitute Part Grouping Explanation

Substitution of the SS110L RUG is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 100 V
Current - Average Rectified (Io): Must equal or exceed 1 A
Package / Case: Must be DO-219AB (Sub SMA / SMF)
Mounting Type: Must be Surface Mount
Technology: Must be Schottky
RoHS Status: Must be ROHS3 Compliant

Secondary Compatibility Parameters:

Voltage - Forward (Vf) (Max) @ If: Acceptable range 800 mV to 860 mV @ rated current
Speed: Must maintain Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature - Junction: Acceptable range -55°C to 150°C minimum; 175°C maximum acceptable
Current - Reverse Leakage @ Vr: Lower values indicate superior performance

Substitute parts are grouped into two categories: Parametrically Equivalent (identical electrical ratings) and Similar (equal or higher current ratings with compatible electrical characteristics).

Engineering Selection Recommendations

Parametrically Equivalent Substitutes (Direct Replacement):

The SS110L (Taiwan Semiconductor Corporation) is a parametrically equivalent substitute with identical electrical specifications. However, this part is classified as "Not For New Designs," indicating end-of-life status. For new designs, this part should not be selected.

Active Equivalent Substitutes (Recommended for New Designs):

The SS1FH10-M3/H and SS1FH10HM3/H (Vishay General Semiconductor - Diodes Division) are direct electrical equivalents with Active product status. Both maintain 100 V reverse voltage and 1 A average rectified current ratings. The SS1FH10HM3/H carries AEC-Q101 automotive qualification, suitable for automotive applications. Both parts feature improved reverse leakage current (5 µA versus 50 µA) and extended operating temperature range to 175°C. These parts are suitable for direct replacement in new designs.

Higher Current Capacity Substitutes:

The SS2FH10-M3/H and SS2FH10HM3/H (Vishay General Semiconductor - Diodes Division) provide 2 A average rectified current capacity while maintaining 100 V reverse voltage rating. These parts are suitable for applications requiring higher current handling. The SS2FH10HM3/H includes AEC-Q101 automotive qualification. Both parts feature improved reverse leakage current and extended operating temperature range to 175°C. Selection of these parts is appropriate when circuit design permits higher current ratings and when enhanced thermal performance is beneficial.

All recommended substitutes maintain ROHS3 compliance and DO-219AB package compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SS110L RUG be directly replaced with the SS110L?

A: The SS110L is parametrically equivalent with identical electrical specifications. However, the SS110L is classified as "Not For New Designs." For new designs, select SS1FH10-M3/H or SS1FH10HM3/H instead.

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

A: Both parts are electrically identical with 100 V reverse voltage and 1 A average rectified current. The SS1FH10HM3/H includes AEC-Q101 automotive qualification and is available in Tape & Reel packaging. The SS1FH10-M3/H is available in Cut Tape & Digi-Reel packaging. Selection depends on packaging requirements and automotive qualification necessity.

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

A: Yes. These parts provide 2 A average rectified current capacity while maintaining 100 V reverse voltage rating and DO-219AB package compatibility. They are suitable substitutes when circuit design permits higher current ratings. The SS2FH10HM3/H includes AEC-Q101 automotive qualification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, consistent with the SS110L RUG.

Q: What is the package compatibility between the SS110L RUG and substitute parts?

A: All substitute parts use the DO-219AB package (Sub SMA / SMF), ensuring mechanical and electrical compatibility with the SS110L RUG footprint.

Q: How does reverse leakage current differ between the main part and substitutes?

A: The SS110L RUG specifies 50 µA reverse leakage current at 100 V. Vishay substitutes (SS1FH10 and SS2FH10 series) specify 5 µA reverse leakage current, representing a 10-fold improvement in leakage performance.

Q: What is the operating temperature difference between the SS110L RUG and Vishay substitutes?

A: The SS110L RUG operates from -55°C to 150°C junction temperature. Vishay substitutes operate from -55°C to 175°C, providing 25°C additional high-temperature margin.
