Procurement Notes

Verify the exact suffix CU34Q4S1 against manufacturer documentation to confirm binning codes and packaging specifications. Ensure compatibility with existing PCB footprints for T-1 3/4 packages. Check RoHS compliance status via official datasheets prior to integration. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when a distinct blue indicator is required with oval form factor constraints. Consider the 3.4 V forward voltage drop for circuit design calculations. Evaluate the 2300 mcd intensity against ambient lighting conditions. Verify that the 70° x 30° viewing angle meets visibility requirements for the intended enclosure design.
