LED Indication - Discrete Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer specifications may undergo revisions. Confirm that the through-hole lead configuration matches your PCB footprint requirements. Ensure compatibility with standard assembly processes for 3.1mm axial LEDs. Cross-reference the part number LTL1CHFL4D with official Lite-On documentation to validate current ratings and optical characteristics before finalizing procurement plans.

LED Indication - Discrete Selection Notes

Select this component when a distinct amber visual signal is required for equipment status monitoring. The 45-degree viewing angle offers a balance between focused directionality and broad visibility. Consider the 3.1mm size constraint for tight panel spaces. The diffused lens helps reduce glare while maintaining sufficient brightness for ambient light conditions. Evaluate thermal management needs based on the 20mA forward current specification.

LED Indication - Discrete Part Context

This part belongs to Lite-On's standard discrete LED lineup, characterized by consistent optical performance and mechanical reliability. The LTL series is widely recognized for use in general-purpose electronics where clear visual feedback is essential. The 3.1mm form factor represents a common industry standard for panel-mount indicators, ensuring compatibility with existing tooling and fixture designs used in manufacturing environments.

LED Indication - Discrete Replacement Considerations

Direct substitutes must match the 3.1mm diameter, amber color, and through-hole configuration. Verify that alternative components maintain similar luminous intensity ranges and forward current tolerances. Check mechanical dimensions, particularly the 6.50mm height limit, to ensure fit within the designated enclosure space. Optical properties like viewing angle should be compared to maintain consistent user interface visibility.
