Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based solely on the matching and compatible parameters: diode configuration, Schottky technology, reverse voltage rating, average rectified current per diode, forward voltage drop at specified current, fast recovery speed, reverse leakage current, junction operating temperature range, mounting type, and chassis mount mechanical package. Only parts meeting these criteria are included as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

FST7335M is classified as obsolete. The substitute part 81CNQ035 from SMC Diode Solutions is listed as active, with ROHS3 compliance and REACH affected status. Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited) and share ECCN and HTSUS classifications. Engineering selection can proceed based on part status and compliance data provided.

Frequently Asked Questions (FAQ)

Q1: What electrical characteristics must be matched for substitution in diode rectifier modules?
A1: Diode configuration, Schottky technology, reverse voltage (Vr), average rectified current (Io), forward voltage drop (Vf) at specified current, recovery speed, reverse leakage current, and operating temperature range are required for substitution.

Q2: Is package compatibility required for module substitution?
A2: Yes. Chassis mount and specific package/case types must be matched for direct replacement.

Q3: Does compliance (RoHS or REACH) affect substitute part selection?
A3: Compliance status (RoHS, REACH) affects supply chain and regulatory requirements and must be considered during the selection process.

Q4: How does the product status of the main and substitute parts affect engineering selection?
A4: The main part (FST7335M) is obsolete, therefore substitute selection is necessary. The substitute (81CNQ035) is active, supporting continuity of supply.

Q5: Are there differences in key ratings that must be considered with substitutes?
A5: Provided ratings such as current, forward voltage, reverse leakage, and operating temperature can differ. Only parameters explicitly listed in the comparison table should be considered for compatibility.
