Key Parameters

Substitute Part Grouping Explanation

Substitution of the FESB8CTHE3_A/P diode is determined by matching critical electrical and mechanical parameters, specifically: diode type category, maximum DC reverse voltage, average rectified current, forward voltage at rated current, recovery speed, reverse leakage current, automotive grade qualification, mounting configuration, package type, operating temperature range, RoHS compliance, moisture sensitivity level, REACH status, ECCN, and HTSUS assignment. Only diodes matching these attributes within defined tolerances can be considered as substitute parts.

Parameter Comparison

Engineering Selection Recommendations

The FESB8CTHE3_A/P diode is obsolete. Substitute selection should prioritize active parts with matching certifications, compliance (ROHS3, REACH), automotive grade, and equivalent classification under ECCN and HTSUS. Moisture Sensitivity Level must remain at 1 (Unlimited) for direct process compatibility. Alternative models must be evaluated strictly within the electrical limits and regulatory requirements as specified above.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for a substitute to be used?
A: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Speed, and Current - Reverse Leakage @ Vr must match within stated values.

Q: Are automotive grade and compliance certifications mandatory for substitutes?
A: Yes, substitutes must have equivalent automotive grade, RoHS status, REACH status, ECCN, HTSUS, and Moisture Sensitivity Level as per original specifications.

Q: Can a substitute in a different package be used?
A: Only if surface-mount configuration and package case type meet application and layout constraints. Compare the package / case details between original and substitute.

Q: Is a higher junction temperature range acceptable?
A: Substitute junction temperature must encompass or improve upon the original part’s specification, according to provided data.

Q: If the substitute has lower current capacity, is it suitable?
A: The substitute must meet or exceed the current requirement as per the defined key parameters.

Q: Why is the FESB8CTHE3_A/P obsolete?
A: Only the part status "Obsolete" is indicated. No further details are provided in the input parameters.
