Key Parameters

Substitute Part Grouping Explanation

Substitution is based exclusively on matching or exceeding critical parameters, which include: diode configuration, technology, maximum reverse voltage, average rectified current per diode, forward voltage at rated current, reverse leakage current at rated voltage, speed, operating temperature range, mounting type, and package category. Only parts that match the structure of 1 pair common cathode Schottky diode arrays, rated at 45 V reverse voltage, with comparable or higher average rectified current and suitable package for chassis mounting are considered as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Based on product status and compliance information, FST6345M is classified as Obsolete, whereas 80CNQ045 is listed as Active and ROHS3 Compliant. Both parts share the same ECCN and HTSUS codes and have comparable technical characteristics within the specified parameters. The moisture sensitivity levels are equivalent at MSL 1 (unlimited).

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when selecting a substitute for the FST6345M Schottky diode array?
A1: Critical parameters include diode configuration, technology, maximum reverse voltage, average rectified current per diode, forward voltage at rated current, reverse leakage current at rated voltage, speed, operating temperature range, mounting type, and package.

Q2: Are the packages of FST6345M and 80CNQ045 identical?
A2: FST6345M uses the D61-3M package, while 80CNQ045 uses the PRM2 package. Both are chassis mount packages, but their dimensions and footprints must be reviewed for mechanical compatibility.

Q3: How do the electrical characteristics of the 80CNQ045 compare to the FST6345M?
