Key Parameters

Substitute Part Grouping Explanation

Substitution for the SS320F-HF strictly considers electrical and mechanical compatibility. Key parameters for grouping include technology type (Schottky), maximum DC reverse voltage, average rectified current, forward voltage drop at rated current, reverse leakage current, speed of recovery, mounting type, and package outline. Only parts matching these parameters in the defined product category Diodes, Rectifiers, and maintaining compliance status, are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SS320F-HF and SK320A diodes are both active parts with ROHS3 compliance and an unlimited Moisture Sensitivity Level (MSL 1). Both comply with ECCN EAR99 and HTSUS 8541.10.0080 classifications. Selection should prioritize inventories of active, compliant parts within the specified category and packaging, ensuring direct compatibility based on listed parameters.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting the SS320F-HF in rectifier designs?
A1: Substitute selection is determined by matching technology type (Schottky), rated DC reverse voltage, average rectified current, forward voltage at rated current, recovery speed, package type, and surface mount compatibility.

Q2: How does the package difference (SMAF vs. DO-214AC (SMA)) affect substitution?
A2: Both SS320F-HF and SK320A use the DO-214AC, SMA industry standard package, which supports surface mount applications. Package compatibility is based strictly on supplier device designation.

Q3: Is reverse leakage current relevant to substitution compatibility?
A3: Reverse leakage current is a key electrical parameter in Schottky diode selection. Both SS320F-HF and SK320A specify reverse leakage at 200 V, with SK320A listing a lower value.

Q4: Is compliance with ROHS3 mandatory for substitution?
A4: Substitution requires parts with equivalent compliance status. Both SS320F-HF and SK320A are ROHS3 Compliant, meeting regulatory requirements.

Q5: What is the importance of matching moisture sensitivity level (MSL) during substitution?
A5: Both candidates are specified at MSL 1 (unlimited), which assures suitability for standard reflow and storage conditions across manufacturing processes.
