Current Sensors Procurement Notes

Verify the specific suffix SP33 indicates the 3.3V supply variant when sourcing replacements. Confirm RoHS compliance status matches project requirements. Ensure the package type aligns with existing PCB footprints. Check lifecycle status to confirm active production availability before finalizing procurement plans.

Current Sensors Selection Notes

Select this component when a low-voltage 3.3V interface is required for current sensing applications. The bidirectional feature makes it suitable for AC or reversible DC loads. Consider the 10A rating limit and thermal performance within the specified temperature range during system design.

Current Sensors Part Context

This part belongs to the HLSR-P/SP33 series from LEM USA Inc., which includes variants such as HLSR 20-P/SP33 and HLSR 32-P/SP33. The series shares common design principles but differs in primary current ratings. The SP33 suffix specifically denotes the 3.3V supply voltage configuration.

Current Sensors Replacement Considerations

Direct substitutes include other HLSR-P/SP33 series parts like HLSR 20-P/SP33 if higher current capacity is needed. Verify pinout compatibility and supply voltage requirements when considering alternative manufacturers' equivalent components.
