LTL-4222N-002

LED Indication - Discrete Overview

The LTL-4222N-002 is a single-color red LED from the Lite-On LTL series, housed in a T-1 (3 mm) through-hole package with a dome lens. It operates at a forward current of 20 mA and a forward voltage of 2 V, emitting light at a peak wavelength of 635 nm. The component features a minimum luminous intensity of 29 mcd and a viewing angle of 45 degrees. Rated for power dissipation of 100 mW, it functions within a temperature range of -55 °C to +100 °C.

LED Indication - Discrete Procurement Notes

Verify the specific suffix against official Lite-On documentation to confirm exact optical and electrical tolerances. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications before finalizing orders.

LED Indication - Discrete Selection Notes

Select this component when a standard 3 mm red indicator is required with defined intensity thresholds. Consider the 45-degree viewing angle for directional applications. Verify thermal management requirements against the 100 mW power rating and ensure the through-hole footprint matches the target PCB design constraints.

LED Indication - Discrete Part Context

This part belongs to the LTL series of T-1 LEDs, representing a legacy but widely used form factor. It serves as a fundamental discrete optoelectronic component for basic visual feedback. The series emphasizes cost-effective manufacturing while maintaining consistent photometric performance across production batches.

LED Indication - Discrete Replacement Considerations

Direct substitutes include the LTL-4221N or other LTL-422x variants within the same family. Verify pin compatibility and spectral overlap when replacing with generic T-1 red LEDs from other manufacturers.
