Substitute Part Grouping Explanation

Substitution is strictly based on matching or exceeding electrical parameters, mounting, packaging type, product status, and compliance. The acceptable substitute parts:

Utilize Schottky technology.
Feature the same maximum DC reverse voltage (40 V).
Provide average rectified current at or above the specified value (1A).
Maintain comparable forward voltage and switching speed.
Match package, mounting, and compliance profile for drop-in replacement.
Share an active product status.

Key parameters for substitution: Technology, Voltage - DC Reverse (Vr), Current - Average Rectified (Io), Voltage - Forward (Vf) @ If, Speed, Current - Reverse Leakage @ Vr, Mounting Type, Package / Case, Supplier Device Package, Operating Temperature range, RoHS/REACH/Compliance status.

Engineering Selection Recommendations

All listed substitute parts SD2010S040S1R0, SD2010S040S2R0, and SD2010S040S3R0 possess an active product status and meet or exceed the RoHS3 compliance and moisture sensitivity level (1, Unlimited) specifications of the original CD2010-B140. REACH status must be matched if required for regulated markets. For selection, consider compliance status and product availability as per provided parameters.

Frequently Asked Questions (FAQ)

Q: What criteria were used to determine if a diode rectifier is a substitute for CD2010-B140?
A: Substitution is based on matching technology (Schottky), DC reverse voltage, forward and reverse current ratings, switching speed, mounting style, operating temperature range, and compliance status.

Q: Are all substitute parts suitable for the same mounting configuration as CD2010-B140?
A: Yes, all substitutes are surface mount devices in the 2010 or compatible 2-SMD, No Lead packages.

Q: How do I select between SD2010S040S1R0, SD2010S040S2R0, and SD2010S040S3R0?
A: Selection can be based on current rating requirements and regulatory compliance (RoHS3, REACH status). Ensure operational parameters and the package are suitable for the application environment.

Q: What compliance considerations are shared among the substitute parts?
A: All substitutes are RoHS3 compliant and rated at moisture sensitivity level 1 (Unlimited). REACH status is specified for each part.

Q: Does the operating temperature range differ among the listed substitutes?
A: The substitute diodes feature a range of -55°C ~ 125°C; CD2010-B140 covers -40°C ~ 125°C. When selecting for temperature-critical applications, refer to provided values.

Q: Is there a difference in forward voltage and reverse leakage among substitute parts?
A: The substitute parts have a lower maximum forward voltage (500 mV @ respective current) and reverse leakage current of 200 µA @ 40 V, compared to the original's 550 mV and 100 µA respectively. Evaluate these values according to circuit tolerance.
