SS110L RTG Equivalent & Substitute Parts

Part Overview

The SS110L RTG 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 DO-219AB (Sub SMA) surface mount package. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives with enhanced electrical characteristics or automotive-grade qualifications.

Substitute Part Grouping Explanation

Substitution of the SS110L RTG is determined by strict electrical and mechanical parameter matching within the Schottky diode rectifier category. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V minimum
Current - Average Rectified (Io): 1 A minimum
Package / Case: DO-219AB (Sub SMA / SMF)
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

Operating Temperature Range: -55°C minimum to 150°C maximum
RoHS Compliance: ROHS3 Compliant
Moisture Sensitivity Level: MSL 1 (Unlimited)

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications) and similar parts (enhanced specifications within the same package and voltage class). Parts with higher current ratings (2 A) are classified as similar rather than direct equivalents, as they exceed the primary specification but remain compatible for applications requiring the SS110L RTG.

Engineering Selection Recommendations

Direct Equivalent Selection:

The SS1FH10-M3/H and SS1FH10HM3/H (Vishay eSMP® series) are direct electrical equivalents to the SS110L RTG, maintaining identical voltage and current ratings with the same DO-219AB package. Both parts are Active product status. The SS1FH10HM3/H includes AEC-Q101 automotive qualification, making it suitable for applications requiring automotive-grade components. The extended operating temperature range (-55°C to 175°C versus -55°C to 150°C) provides additional thermal margin.

Higher Current Alternative:

The SS2FH10-M3/H and SS2FH10HM3/H (Vishay eSMP® series) provide 2 A current rating in the same 100 V package. These parts are suitable for applications where the SS110L RTG specification can accommodate higher current capacity. The SS2FH10HM3/H includes AEC-Q101 automotive qualification. Both maintain Active product status and ROHS3 compliance.

Parametric Equivalent (Legacy Status):

The SS110L (Taiwan Semiconductor Corporation, Tape & Reel packaging) is a parametric equivalent with identical electrical specifications but carries "Not For New Designs" product status. This part is suitable only for replacement or maintenance applications where the original part number must be maintained.

Selection Criteria:

For new designs requiring 1 A rating: Select SS1FH10-M3/H or SS1FH10HM3/H
For automotive applications: Select SS1FH10HM3/H or SS2FH10HM3/H
For higher current capacity (2 A): Select SS2FH10-M3/H or SS2FH10HM3/H
For legacy system maintenance: Use SS110L only when original part number must be preserved

Frequently Asked Questions (FAQ)

Q: Can the SS1FH10-M3/H directly replace the SS110L RTG?

A: Yes. The SS1FH10-M3/H is a direct electrical equivalent with identical voltage (100 V), current (1 A), forward voltage (800 mV @ 1 A), and package (DO-219AB). Both are Schottky rectifier diodes with fast recovery characteristics. The Vishay part is Active product status and offers improved reverse leakage characteristics (5 µA versus 50 µA).

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

A: Both parts are electrically identical with 100 V, 1 A ratings and DO-219AB packaging. The SS1FH10HM3/H includes AEC-Q101 automotive qualification and is available in Cut Tape (CT) & Digi-Reel® packaging, while the SS1FH10-M3/H is available in Tape & Reel (TR) packaging. The SS1FH10HM3/H is suitable for automotive applications.

Q: Can I use the SS2FH10-M3/H (2 A) in place of the SS110L RTG (1 A)?

A: Yes, the SS2FH10-M3/H is compatible for applications where the SS110L RTG specification allows higher current capacity. The 2 A part maintains the same 100 V voltage rating and DO-219AB package. This substitution is suitable when design margins permit higher current handling. The forward voltage is slightly higher (860 mV @ 2 A versus 800 mV @ 1 A).

Q: What does "Not For New Designs" mean for the SS110L part?

A: "Not For New Designs" indicates the part is in legacy status and should not be selected for new product development. It remains available for replacement and maintenance of existing systems. For new designs, select SS1FH10-M3/H or SS1FH10HM3/H instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The SS110L RTG and all listed substitute parts (SS110L, SS1FH10-M3/H, SS1FH10HM3/H, SS2FH10-M3/H, SS2FH10HM3/H) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference in operating temperature range?

A: The SS110L RTG operates from -55°C to 150°C junction temperature. The Vishay substitute parts (SS1FH10 and SS2FH10 series) operate from -55°C to 175°C, providing an additional 25°C upper temperature margin. This extended range is beneficial for high-temperature applications.

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

A: Select either SS1FH10HM3/H (1 A rating) or SS2FH10HM3/H (2 A rating), both of which carry AEC-Q101 automotive qualification. These parts meet automotive reliability and qualification standards while maintaining electrical compatibility with the SS110L RTG.

Q: What packaging options are available for the substitute parts?

A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, and bulk packaging. Select packaging based on manufacturing process requirements. All parts use the same DO-219AB (Sub SMA / SMF) component package.
