• Panel status indication
• Control panel instrumentation

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version and electrical parameters directly from the manufacturer before integration. Confirm that the 5 mm through-hole form factor aligns with the target PCB layout requirements. Ensure compliance with relevant environmental standards for the intended deployment environment.

LED Indication - Discrete Selection Notes

Select this component when a blue visual signal is required in a standard 5 mm housing. Consider the ±30° beam width for directional visibility needs. Evaluate the diffused lens characteristics against clarity requirements for the specific application context.

LED Indication - Discrete Part Context

This part belongs to Vishay's standard LED product series, utilizing a 5 mm package format common in legacy and robust electronic designs. The TLHB5401 variant specifically provides blue illumination, distinguishing it from other color options within the same physical footprint family.

LED Indication - Discrete Replacement Considerations

Cross-reference with TLHR5401 or similar Vishay 5 mm LEDs only if color specifications allow. Verify mechanical dimensions and forward voltage compatibility before substituting with generic equivalents.
