Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based strictly on matching the following key parameters: manufacturer, package type, input voltage range, output voltage and current, isolation voltage, efficiency, mounting type, dimensions, control features, application, temperature range, and required compliance certifications. Only the parameters explicitly specified are used to determine equivalency for DC-DC converter modules in the quarter brick format.

Parameter Comparison

Engineering Selection Recommendations

The main part (BMR4530000/002) is obsolete. The substitute part (BMR4560004/004) is active and offers comparable electrical and mechanical key parameters, including matching input voltage range, output voltage, higher output current and power, compatible mounting, and package dimensions. Compliance is ensured through specified approval agencies and certification standards. Regulatory status and ECCN are consistent across both models.
