Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly based on matching the following parameters: diode configuration, technology, voltage - DC reverse (Vr) (max), mounting type, operating temperature, and package-specific compliance. Only parts with 1 pair common anode configuration, Schottky technology, and 45 V maximum reverse voltage are considered. The average rectified current, forward voltage, speed, and package are included for compatibility evaluation. Substitution is necessary due to the MBRF40045R’s obsolete status, and all substitutes must comply with listed electrical and mechanical criteria.

Parameter Comparison

Engineering Selection Recommendations

MBRF40045R is obsolete; selection of MBRT20045R as a substitute is strictly based on the available product status and maintained RoHS compliance, ECCN, and MSL 1 (Unlimited). MBRT20045R is active and meets the core compliance parameters required for direct substitution within the constraints of this product category.
