Engineering Selection Recommendations
Selection within the provided substitute list is permissible where product status is active and certifications match or exceed the requirements indicated in the original part, specifically ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). Substitutes must also meet ECCN EAR99 for export control compliance.
Frequently Asked Questions (FAQ)
Q: What are the primary criteria for substituting AES2GF-HF in designs?
A: Substitution is based on exact matching of maximum DC reverse voltage, average rectified current, forward voltage at rated current, reverse recovery time (where available), mounting type, package/case, operating temperature range, and compliance certifications.
Q: Is package compatibility ensured among listed substitutes?
A: All substitutes are surface mount diodes within the DO-214AC (SMAF/SMA) and DO-214AA categories, compatible within the outlined mechanical requirements. Specific package codes should be verified against design footprints.
Q: Should RoHS and MSL qualifications be matched when selecting substitutes?
A: Yes. All listed substitutes hold ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the required environmental and reliability criteria.
Q: How do differences in reverse leakage current or recovery time affect substitutability?
A: Only parameters provided are considered for substitutability. Where values differ, refer to the comparison table for reference relative to application needs. Use only values explicitly stated in this engineering reference.
Q: Are all alternative diodes suitable for automotive or high-reliability applications?
A: AES2GF-HF is specified as automotive grade with AEC-Q101 qualification; this is not stated for all substitutes in the list. Only attributes provided herein are considered for substitution.
