Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on the following key parameters in this category: diode configuration, technology, maximum reverse voltage (Vr), average rectified current (Io), forward voltage (Vf) at the specified current, switching speed, reverse leakage current, operating temperature range, mounting type, and package. Only parts matching or exceeding these values and sharing the identified attributes are considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts is based on the obsolete status of FST6315M and the active status, RoHS3 compliance, and REACH status of 85CNQ015. Both devices have unrestricted moisture sensitivity levels (MSL 1), but package differences must be considered. No additional technical parameters have been introduced in this assessment.

Frequently Asked Questions (FAQ)

Q1: What key parameters were considered for substituting FST6315M?
A1: Substitution criteria included diode configuration, technology, voltage rating, current rating, forward voltage, speed, reverse leakage, operating temperature, mounting type, and moisture sensitivity level.

Q2: Is package compatibility required for direct substitution?
A2: Package/case must be compared directly; FST6315M uses D61-3M while 85CNQ015 uses PRM2. Evaluate physical fit and compatibility in the target assembly.

Q3: Does RoHS compliance affect substitute selection?
A3: RoHS status is used to verify environmental compliance if required. 85CNQ015 is ROHS3 compliant.

Q4: Are there any restrictions due to product status?
A4: FST6315M is obsolete; 85CNQ015 is active. Preference should be given to active products for future procurement.

Q5: Can differences in reverse leakage current and operating temperature influence selection?
A5: Comparison is made only on provided specifications. Differences must be referenced directly in terms of application tolerance within the specification envelope.

Q6: Is moisture sensitivity level comparable between the main and substitute parts?
A6: Both FST6315M and 85CNQ015 have a Moisture Sensitivity Level of 1 (Unlimited), indicating identical handling requirements in this context.
