Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is strictly based on matching or exceeding the following key allowed parameters in the Schottky diodes and rectifiers category: diode configuration (1 Pair Common Cathode), Schottky technology, maximum reverse voltage (35 V), average rectified current (≥30A), package type (chassis mount), and matching speed characteristics (Fast Recovery ≤500ns, >200mA Io). Only parts meeting all provided criteria are considered suitable equivalents for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The FST6335M is marked as Obsolete. The substitute part 81CNQ035 provided by SMC Diode Solutions is listed as Active with ROHS3 compliance and REACH status. Both parts are classified under the same ECCN and HTSUS, with identical moisture sensitivity level (MSL 1, Unlimited), and both use chassis mount technology. Selection of 81CNQ035 as a substitute adheres strictly to the allowed parameters and compliance status.
