Key Parameters

Substitute Part Grouping Explanation

Substitute selection for MBRF40080 is determined by direct matching of functional and electrical characteristics. These parameters are: diode configuration, technology, reverse voltage rating, average rectified current, forward voltage drop, recovery speed, reverse leakage current, operating junction temperature, mounting type, and package. Each substitute listed conforms to these measured criteria.

Parameter Comparison

Engineering Selection Recommendations

MBRF40080 is an obsolete part, as indicated by its product status field. 403CNQ080 is an active part and is listed as RoHS3 compliant and REACH affected, addressing current regulatory compliance requirements. Both are classified with the same ECCN and HTSUS codes and present identical moisture sensitivity levels. Substitute selection is based solely on these documented status and compliance fields.

Frequently Asked Questions (FAQ)

Q1: What are the necessary electrical parameters for selecting a substitute for MBRF40080?
A: The substitute must match diode configuration, technology type, voltage and current ratings, forward voltage characteristics, reverse leakage specifications, and operating temperature range.

Q2: Are the package types and mounting styles relevant to substitution?
A: Yes, both parts utilize chassis mount, but the package differs (TO-244AB for MBRF40080, PRM4 for 403CNQ080). Compatibility with the existing physical layout must be verified based on these package designations.

Q3: Are there differences in operating temperature ranges?
A: MBRF40080 operates from -55°C to 150°C, while 403CNQ080 extends to -55°C to 175°C.

Q4: Is compliance documentation relevant for substitute selection?
A: Yes, 403CNQ080 is listed as RoHS3 compliant and REACH affected, whereas such details are not specified for MBRF40080.

Q5: Can the substitute operate at the same electrical ratings?
A: Both parts are rated for 80 V DC reverse and 200A average rectified current per diode, and use fast recovery Schottky technology, aligning core electrical functionality.

Q6: Are there inventory differences that impact selection?
A: Inventory levels are provided: MBRF40080 has 886 pieces in stock as obsolete, while 403CNQ080 lists 1178 pieces as active.

Q7: What are the main matching criteria for substitution in diodes, rectifiers category?
A: Electrical ratings, configuration, technology, mounting, and compliance as documented in the source parameters.
