LED Indication - Discrete Procurement Notes

Verify the specific suffix KT to confirm tape-and-reel packaging. Confirm RoHS3 compliance status for regulatory requirements. Check moisture sensitivity level (MSL 2A) for storage and handling protocols. Ensure the 0603 package footprint matches the target PCB layout. Validate the 605 nm wavelength against optical specifications.

LED Indication - Discrete Selection Notes

Select this component for applications requiring a compact 0603 form factor with high brightness relative to size. The 130-degree viewing angle suits wide-area visibility needs. Consider the 2 V forward voltage for low-power circuit compatibility. Verify thermal management capabilities within the specified operating temperature range.

LED Indication - Discrete Part Context

This part belongs to the LTST-C191 series of single-color SMD LEDs from Lite-On. The series offers various color options including red, green, blue, and orange. All variants share similar mechanical dimensions and mounting characteristics, differing primarily in optical output and electrical parameters.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 0603 orange LEDs with compatible pin configurations and similar luminous intensity. Verify forward voltage and wavelength tolerances before substitution. Ensure the replacement part meets the same environmental and reliability standards.
