Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is limited to existing stock or secondary market sources. Verify authenticity and condition carefully when sourcing from non-direct suppliers. Confirm that the specific suffix matches required specifications, as variants may exist. Check RoHS compliance status through official documentation before integration into new designs.

Selection Notes

Select this component only if legacy compatibility is required, as it is discontinued. Ensure the 1812 footprint fits the PCB layout constraints. Verify that the 300 mA current rating meets the application's peak load requirements. Consider the 50 V voltage limit for system safety margins. Evaluate alternative modern equivalents if designing new hardware to ensure long-term supply stability.
