Key Parameters

Substitute Part Grouping Explanation

Substitute parts for FST6320M are strictly selected based on identical or compatible key parameters pertinent to the Diodes, Rectifiers product category. These include diode configuration (1 Pair Common Cathode), Schottky technology, equivalent maximum reverse voltage (20 V), equal or higher average rectified current (per diode), matching fast recovery speed, similar operating temperature range, compatible mounting type (Chassis Mount), and package or case type. All substitutions must also maintain equivalent compliance status, such as Moisture Sensitivity Level (MSL), ECCN, and HTSUS as specified.

Parameter Comparison

Engineering Selection Recommendations

FST6320M is classified as Obsolete, rendering it unavailable for ongoing production requirements. The substitute 87CNQ020 from SMC Diode Solutions maintains active production status and meets compliance requirements, including Moisture Sensitivity Level (MSL: 1 (Unlimited)), ECCN (EAR99), and HTSUS (8541.10.0080). Selection is based on strict adherence to these regulatory and certification parameters.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting FST6320M with 87CNQ020?
A1: Substitution is determined by matching the diode configuration, technology, reverse voltage rating, average rectified current, switching speed, operating temperature range, mounting type, package/case specification, and compliance parameters.

Q2: Is there any difference in package between FST6320M and 87CNQ020?
A2: FST6320M uses the D61-3M package, while 87CNQ020 is provided in the PRM2 package, both are chassis mount types as specified.

Q3: Does the substitute maintain the same compliance and certification status as the original?
A3: Both FST6320M and 87CNQ020 have the same Moisture Sensitivity Level (MSL: 1), ECCN (EAR99), and HTSUS classification as provided.

Q4: Is the operating temperature range of the substitute identical to the original?
A4: Yes, both devices specify an operating temperature junction range of -55°C to 150°C.

Q5: Is there any difference in rectified current rating?
A5: 87CNQ020 provides a higher average rectified current (40A) compared to FST6320M (30A), which meets the minimum required parameter.

Q6: What is the relevance of fast recovery speed in this substitution?
A6: Both the original and substitute specify fast recovery speed (=< 500ns, > 200mA (Io)), satisfying this key parameter for the product category.
