Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching the diode’s Schottky technology, voltage rating (Vr), average rectified current (Io), forward voltage drop (Vf), reverse recovery speed, reverse leakage current, and equivalent chassis mounting package. The substitute part 180NQ040-1 aligns with these key parameters, ensuring compatibility within the defined electrical and mechanical criteria.

Parameter Comparison

Engineering Selection Recommendations

The main part number MBRH15040L is obsolete, necessitating use of available substitutes. Substitute 180NQ040-1 part number is active, RoHS3 compliant, and shares the same ECCN and HTSUS codes. Both components have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), facilitating equivalent handling and storage procedures.

Frequently Asked Questions (FAQ)

Q1: What determines compatibility for diode rectifier substitution?
Compatibility is defined by electrical parameters such as voltage rating (Vr), average rectified current (Io), forward voltage (Vf), reverse leakage current, switching speed, and form factor or package. Only components matching these parameters are considered as substitutes.

Q2: Is the mounting type critical in substitution?
Chassis mount configuration must be retained when substituting, as mechanical interchangeability is defined by mounting parameters and form factor.

Q3: Are the voltage and current ratings identical for the substitute part?
Both original and substitute diodes have a maximum reverse voltage of 40 V. Substitute 180NQ040-1 offers a higher current rating of 180 A compared to the original's 150 A.

Q4: How does the reverse leakage current compare?
MBRH15040L features a reverse leakage of 5 mA at 40 V, while 180NQ040-1 has 15 mA at 40 V.

Q5: Is agency compliance relevant for engineering selection?
MSL, RoHS, ECCN, and HTSUS codes are matched. These certifications must be considered for regulatory compliance in application environments.

Q6: Does the package variant affect substitution?
Package designation must be considered, as MBRH15040L uses D-67 and 180NQ040-1 uses Half-Pak PRM1-1. The mechanical footprint and connection type should correspond to application requirements.
