Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly by matching or exceeding the key parameters of the main part number (FST8380M) without deviation. The evaluated criteria for substitution include: diode configuration, Schottky technology, maximum DC reverse voltage (Vr), average rectified current (Io), maximum forward voltage (Vf) at the specified current, recovery speed, reverse leakage current, operating temperature range, mounting type, and moisture sensitivity. Mechanical compatibility via package and supplier device package is also considered. Only parts matching these fields are considered valid equivalents.

Parameter Comparison

Engineering Selection Recommendations

The FST8380M is classified as obsolete. The alternative part listed, 83CNQ080S2, is active and retains the same compliance identifications: ECCN EAR99 and HTSUS 8541.10.0080. It is RoHS3 compliant and REACH affected, and features moisture sensitivity level 1 (unlimited), matching operational parameters required for direct substitution in regulated environments. Product selection should be based on status to ensure continuity of supply and support.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting FST8380M with another diode module?
A1: The primary criteria are matching diode configuration, Schottky technology, maximum DC reverse voltage (Vr), average rectified current (Io), equivalent or superior recovery speed, reverse leakage, operating temperature, and comparable mechanical compatibility in mounting and package.

Q2: How critical is the package/case when selecting a substitute like the 83CNQ080S2?
A2: The package/case affects mechanical and thermal integration. Substitutes listed here use a chassis mount format and have a specific package/case code, which must be checked for system compatibility.

Q3: Are substitute parts compliant with environmental regulations?
A3: The 83CNQ080S2 diode module is RoHS3 compliant and REACH affected, with ECCN and HTSUS codes provided, ensuring consistent regulatory status with the main part.

Q4: Is the electrical performance identical between FST8380M and 83CNQ080S2?
A4: Key parameters such as maximum DC reverse voltage, average rectified current, and technology are identical. Minor differences may exist in forward voltage and test conditions, as specified in the comparison table.

Q5: Why is an alternative to the FST8380M required?
A5: FST8380M is listed as obsolete, meaning it is no longer manufactured or supported, necessitating the identification of an alternative to ensure ongoing design and maintenance compatibility.
