LED Indication - Discrete Procurement Notes

Verify the current lifecycle status before design finalization, as this part may be obsolete or discontinued. Confirm that the radial T-1 package dimensions align with the target PCB footprint. Ensure the 3.8V forward voltage drop is compatible with the driving circuit's supply rails and current limiting resistors to maintain the specified 150mcd output.

LED Indication - Discrete Selection Notes

Select this component when a bright blue visual indicator is required in through-hole designs. The T-1 form factor suits applications needing a compact yet visible signal source. Consider the 35-degree viewing angle for directional visibility requirements. The 150mcd rating ensures adequate brightness for most industrial and consumer panel applications under standard operating conditions.

LED Indication - Discrete Part Context

This LED belongs to onsemi’s discrete optoelectronic portfolio, specifically designed for visual indication tasks. It complements other components in power management and signal processing systems by providing user feedback. The T-1 series offers standardized mechanical dimensions for easy integration into various enclosure designs requiring reliable optical signaling.

LED Indication - Discrete Replacement Considerations

Check for direct substitutes within the same T-1 radial family. Verify that any replacement maintains the 3.8V forward voltage and 150mcd intensity specifications. Ensure the new component matches the 430nm peak wavelength to preserve color consistency in the assembly.
