Substitute Part Grouping Explanation

Substitute parts are selected strictly based on identical specifications in the following parameters:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Recovery Time & Rectified Current)
• Reverse Recovery Time (trr)
• Current - Reverse Leakage @ Vr
• Mounting Type
• Package / Case
• Supplier Device Package
• Operating Temperature - Junction
• RoHS Status
• MSL
• REACH Status
• Product Status
• Qualification

All substitute parts listed share matching values for these parameters with the RFN5BM3SFHTL, ensuring strict parametric compatibility for direct substitution within the Diodes, Rectifiers product category.

Parameter Comparison

Engineering Selection Recommendations

The RFN5BM3SFHTL and the substitute RFN5BGE3STL are both active, AEC-Q101 qualified, ROHS3 compliant, and REACH unaffected. Both parts share MSL 1 (unlimited floor life at ≤30°C/85% RH), confirming appropriate suitability in automotive and industrial applications where regulatory and compliance status is critical. Selection can be based solely on inventory status and supply chain logistics.
