SS210L Equivalent & Substitute Parts

Part Overview

The SS210L is a 2A, 100V Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-123 package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. The identification of equivalent and substitute parts is necessary to support existing designs, legacy system maintenance, and procurement continuity where the original part number is unavailable or discontinued.

Substitute Part Grouping Explanation

Substitution of the SS210L is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 850 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Package Compatibility Considerations: Substitute parts may utilize different surface mount package variants (SOD-123, SOD-123W, SOD-123F) provided they maintain identical electrical performance and are compatible with the PCB footprint and assembly process of the original design.

The SS210L has two identified substitutes: SS210LW (Taiwan Semiconductor Corporation) and DSS210 (SMC Diode Solutions). Both maintain the core electrical specifications required for direct functional replacement.

Engineering Selection Recommendations

SS210LW (Taiwan Semiconductor Corporation)

The SS210LW is the manufacturer-recommended substitute for the SS210L. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications. The SS210LW is classified as "Active" product status, ensuring ongoing availability and support. The part maintains ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original SS210L. The primary difference is the package variant (SOD-123W versus SOD-123) and improved reverse leakage characteristics (20 µA versus 100 µA at 100 V). The SS210LW includes Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited shelf life without moisture control. This part is suitable for direct replacement in applications where the SOD-123W footprint is compatible with the PCB design.

DSS210 (SMC Diode Solutions)

The DSS210 is a functionally equivalent substitute manufactured by SMC Diode Solutions. All critical electrical parameters match the SS210L specification: 100 V reverse voltage, 2 A average rectified current, 850 mV forward voltage at 2 A, and fast recovery switching characteristics. The DSS210 is classified as "Active" product status. The part is ROHS3 compliant and includes MSL 1 rating. The DSS210 utilizes the SOD-123F package variant. Two differences exist relative to the SS210L: reverse leakage current is higher (500 µA versus 100 µA at 100 V), and REACH status is "Affected" rather than "Unaffected." The higher reverse leakage may impact applications with strict leakage current requirements. The DSS210 is suitable for replacement in applications where the SOD-123F footprint is compatible and where the elevated reverse leakage specification is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the SS210LW be used as a direct replacement for the SS210L?

A: The SS210LW is electrically equivalent to the SS210L across all critical parameters: 100 V reverse voltage, 2 A average rectified current, 850 mV forward voltage at 2 A, and fast recovery switching characteristics. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical operating temperature ranges and RoHS compliance. The primary consideration is package compatibility: the SS210LW uses SOD-123W packaging while the SS210L uses SOD-123. Verify that the PCB footprint and assembly process accommodate the SOD-123W package before implementation.

Q: What is the difference between the SS210L and SS210LW packages?

A: The SS210L uses SOD-123 packaging, while the SS210LW uses SOD-123W packaging. Both are surface mount packages for Schottky rectifier diodes. The SOD-123W variant is a wider version of the standard SOD-123 package. PCB footprint compatibility must be confirmed before substitution. Consult the respective component datasheets for precise dimensional specifications.

Q: Is the DSS210 suitable for all applications using the SS210L?

A: The DSS210 is electrically equivalent to the SS210L for the core specifications: 100 V reverse voltage, 2 A average rectified current, 850 mV forward voltage at 2 A, and fast recovery switching characteristics. However, the DSS210 has higher reverse leakage current (500 µA at 100 V) compared to the SS210L (100 µA at 100 V). Applications with strict reverse leakage requirements may not be suitable for the DSS210. Additionally, the DSS210 uses SOD-123F packaging, requiring PCB footprint verification. The DSS210 is manufactured by SMC Diode Solutions rather than Taiwan Semiconductor Corporation.

Q: Why is the SS210L marked as "Not For New Designs"?

A: The "Not For New Designs" status indicates that Taiwan Semiconductor Corporation has superseded this part in their product line. The SS210LW is the active replacement. For new designs, the SS210LW is the recommended choice due to its active product status and ongoing manufacturer support. The SS210L remains available for legacy system support and maintenance applications.

Q: What are the regulatory compliance differences between the substitute parts?

A: All three parts (SS210L, SS210LW, and DSS210) are ROHS3 compliant. The SS210L and SS210LW maintain REACH Unaffected status, while the DSS210 has REACH Affected status. The REACH Affected designation for the DSS210 indicates that the substance composition may be subject to REACH regulatory requirements. Verify compliance requirements for your specific application and regulatory jurisdiction before selecting the DSS210.

Q: Can reverse leakage current differences affect circuit performance?

A: Reverse leakage current differences exist between the substitute parts: SS210L (100 µA @ 100 V), SS210LW (20 µA @ 100 V), and DSS210 (500 µA @ 100 V). In applications where reverse leakage contributes significantly to circuit power consumption, standby current, or signal integrity, these differences may be relevant. The SS210LW exhibits the lowest reverse leakage, while the DSS210 exhibits the highest. Evaluate circuit requirements and thermal performance implications when selecting between these parts.

Q: Are there inventory considerations for selecting a substitute?

A: Inventory availability is subject to change. At the time of this documentation, the SS210LW has 27,987 pieces in stock, the DSS210 has 36,200 pieces in stock, and the SS210L has 15,400 pieces in stock. Inventory levels should be confirmed with the supplier before finalizing procurement decisions.
