Equivalent & Substitute Parts for MBRH15045L

Part Overview

The GeneSiC Semiconductor MBRH15045L is a Schottky diode rated for 45 V, 150 A, chassis mount, with a D-67 package. The product status is obsolete, making it necessary to identify substitute parts for ongoing designs and maintenance. Potential replacements must match the key electrical and mechanical parameters strictly specified for the diodes, rectifiers category.

Substitute Part Grouping Explanation

Substitute selection is strictly based on matching the key electrical and mechanical parameters as provided: voltage rating (Vr), current rating (Io), forward voltage (Vf), recovery speed, reverse leakage current, mounting type, and package/case. Substitutes must meet or exceed the specifications of the original component within the same product category and package constraints.

Engineering Selection Recommendations

The MBRH15045L part is obsolete. Substitute VS-180NQ045PBF is listed as active and is ROHS3 compliant and REACH unaffected, with a matching Moisture Sensitivity Level (MSL 1, Unlimited). Both parts share the same ECCN and HTSUS codes. Selection should be based on the active status and compliance details of the substitute part.

Frequently Asked Questions (FAQ)

Q: What parameters must match for a diode, rectifier substitute?
A: Voltage - DC Reverse (Vr), current - average rectified (Io), forward voltage (Vf), speed, reverse leakage current, mounting type, and package/case are the mandatory parameters for substitution.

Q: Is package compatibility necessary when substituting Schottky diodes?
A: Yes, mechanical compatibility such as package/case and mounting type must match to ensure fit and proper thermal characteristics.

Q: Can electrical parameters exceed the original part when selecting a substitute?
A: Substitutes may have higher ratings as long as they do not violate the specified maximum voltage, current, and other key parameters.

Q: How does product status influence substitution selection?
A: Active status indicates continued availability. For obsolete parts, selection should prioritize substitutes listed as active.

Q: Is RoHS and REACH compliance relevant for part selection?
A: Compliance status such as ROHS3 and REACH unaffected ensures suitability for designs requiring environmental certifications.
