Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS210HE3-LTP are qualified based on the following criteria:

Electrical Parameters (Critical):

• 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

Mechanical Parameters (Critical):

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Compliance Parameters (Critical):

• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain these core parameters. Variations in secondary parameters such as reverse leakage current and junction capacitance are noted but do not disqualify substitution when primary electrical and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

ACDBA2100-HF (Comchip Technology): This substitute maintains all critical electrical parameters and automotive compliance requirements. Reverse leakage current is 200 µA compared to 100 µA in the original part, remaining within acceptable operational margins. AEC-Q101 qualification and ROHS3 compliance are confirmed. This part is suitable for direct substitution in automotive applications.

SK210AH (Taiwan Semiconductor Corporation): This substitute meets all primary electrical specifications and automotive qualification standards. Capacitance data is not provided; however, all other critical parameters including voltage, current, forward drop, and temperature range are equivalent. AEC-Q101 qualification and ROHS3 compliance are confirmed. This part is suitable for direct substitution.

SS210-HF (Comchip Technology): This substitute maintains voltage, current, and forward drop specifications. Reverse leakage current is 300 µA and junction capacitance is 80 pF, both slightly elevated compared to the original part. Automotive grade and AEC-Q101 qualification are not explicitly specified in the provided data. ROHS3 compliance and MSL 1 are confirmed. Suitability for automotive applications should be confirmed based on specific design requirements.

SS210A (HY Electronic (Cayman) Limited): This substitute meets all primary electrical parameters and holds AEC-Q101 automotive qualification. Reverse leakage current is 1 mA and junction capacitance is 200 pF, both significantly higher than the original part. REACH status is listed as Affected, whereas the original part is REACH Unaffected. These differences may impact circuit performance in applications sensitive to leakage current or capacitance. Suitability depends on design margin requirements.

Frequently Asked Questions (FAQ)

Q: Can the ACDBA2100-HF replace the SS210HE3-LTP in all applications?

A: The ACDBA2100-HF maintains equivalent voltage, current, and forward drop specifications. The reverse leakage current is 200 µA versus 100 µA in the original part. Both parts hold AEC-Q101 qualification and ROHS3 compliance. Substitution is valid when circuit design tolerates the specified leakage current range.

Q: What is the significance of the reverse leakage current variation among substitute parts?

A: Reverse leakage current affects power dissipation and circuit performance in high-impedance applications. The SS210HE3-LTP and SK210AH specify 100 µA, ACDBA2100-HF specifies 200 µA, SS210-HF specifies 300 µA, and SS210A specifies 1 mA. Parts with higher leakage may require design verification in applications where leakage current is a critical parameter.

Q: Are all substitute parts qualified for automotive applications?

A: The SS210HE3-LTP, ACDBA2100-HF, SK210AH, and SS210A all hold AEC-Q101 automotive qualification. SS210-HF does not have automotive grade or AEC-Q101 qualification explicitly specified in the provided data. Confirmation of automotive suitability is required for SS210-HF before use in automotive designs.

Q: Do all substitute parts use the same package?

A: All substitute parts use the DO-214AC (SMA) surface mount package. Mechanical compatibility with existing PCB layouts and assembly processes is maintained across all listed substitutes.

Q: What is the difference between ROHS3 Compliant and REACH Unaffected status?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive requirements. REACH Unaffected indicates the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. The SS210HE3-LTP is REACH Unaffected, while SS210A is REACH Affected. This distinction may affect supply chain documentation and regulatory compliance in certain jurisdictions.

Q: Can the SS210-HF be used as a substitute if automotive qualification is required?

A: The SS210-HF does not have automotive grade or AEC-Q101 qualification specified in the provided data. Use in automotive applications requires confirmation of qualification status from the manufacturer before substitution.

Q: How does junction capacitance variation affect circuit performance?

A: Junction capacitance affects switching speed and high-frequency performance. The SS210HE3-LTP specifies 70 pF, ACDBA2100-HF specifies 70 pF, SS210-HF specifies 80 pF, and SS210A specifies 200 pF. Applications operating at high switching frequencies or with tight timing requirements should account for capacitance differences.

Q: Are all substitute parts available in the same packaging format?

A: The SS210HE3-LTP is supplied in Tape & Reel (TR) format. ACDBA2100-HF, SK210AH, and SS210A are supplied in Tape & Reel (TR) format. SS210-HF is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format differences may affect procurement and assembly processes.
