Key Parameters

Substitute Part Grouping Explanation

Substitution decisions for MBRT40040L are based strictly on matching the following explicit parameters: diode configuration (1 Pair Common Cathode), Schottky technology, maximum DC reverse voltage (40 V), average rectified current per diode (200A), fast recovery speed, mounting type (Chassis Mount), package type, operating temperature range, and moisture sensitivity level. Only parts with equivalent or directly compatible values for all these fields are grouped as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MBRT40040L is classified as obsolete, while the 400CMQ040 is active. The 400CMQ040 holds ROHS3 compliance and a moisture sensitivity level of 1 (unlimited), directly matching the MBRT40040L’s environmental handling requirements. Both components have identical diode configuration, technology, voltage, and current ratings, aligning with strict substitution parameters defined for the product class.

Frequently Asked Questions (FAQ)

Q1: What key criteria were used to determine the substitute for MBRT40040L?
A1: The substitution is determined strictly by matching diode configuration, Schottky technology, DC reverse voltage rating, average rectified current, recovery speed, mounting method, operating junction temperature range, and moisture sensitivity level.

Q2: Are the chassis mounting type and package dimensions compatible between MBRT40040L and 400CMQ040?
A2: Both parts are chassis mount types, but the package/case designation differs (Three Tower vs. PRM4). Package compatibility must be reviewed based strictly on provided package information.

Q3: Is the forward voltage drop specification a limiting parameter in this substitution?
A3: Both parts specify forward voltage at 200A within a 30 mV range, aligning to the substitution criteria provided.

Q4: What product status considerations apply to the engineering choice?
A4: The MBRT40040L is obsolete. The substitute 400CMQ040 is active, supporting ongoing design and manufacturing continuity.

Q5: How does compliance affect the direct substitution?
A5: Both parts have a Moisture Sensitivity Level (MSL) of 1 (unlimited). The 400CMQ040 further specifies ROHS3 compliance. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080 as provided.
