LED Indication - Discrete Procurement Notes

Verify the specific suffix 'TBKT' against the manufacturer's official datasheet to confirm exact optical binning and packaging specifications. Ensure compatibility with standard reflow soldering profiles for 2-SMD right-angle packages. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly processes.

LED Indication - Discrete Selection Notes

Select this component when a vertical orientation is required for space-constrained designs. The 130-degree viewing angle provides broad visibility compared to narrow-beam alternatives. Verify that the 3.3V forward voltage aligns with the driving circuit's output capabilities.

LED Indication - Discrete Part Context

This part belongs to the LTST-S321 series of single-color LEDs from Lite-On. The series offers various colors and lens styles in a standardized 1208 metric footprint. The TBKT suffix denotes specific optical and packaging attributes within this family.

LED Indication - Discrete Replacement Considerations

Cross-reference with other Lite-On SMD blue LEDs such as LTST-C21TBKT for similar form factors. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers.
