Procurement Notes

This component is officially obsolete and no longer manufactured by Dialight. Procurement must focus on verified parameter-equivalent substitutes such as the 5988391117F or cross-manufacturer alternatives like Bivar SM1204SBWC. Verify that replacement parts match the original electrical and mechanical specifications to ensure circuit compatibility and physical fit within existing designs.

Selection Notes

Select this component only if legacy support is required, as it is discontinued. For new designs, choose active equivalents from the same series or compatible packages. Ensure the substitute maintains the 3.2 V forward voltage and 20 mA current rating. Confirm moisture sensitivity level 3 handling requirements are met during storage and reflow soldering processes to prevent package damage.

Part Context

Part of the Dialight 598 Series SMD LEDs, designed for high-reliability industrial and commercial applications. The series offers various colors and intensities in standard footprints. This specific blue variant provides clear visibility in bright environments due to its high intensity and wide viewing angle, supporting robust visual feedback systems.

Replacement Considerations

Officially confirmed substitutes include Dialight 5988391117F and Bivar SM1204SBWC. Verify dimensional tolerance and pin configuration alignment before integration.
