204YD-A-L is listed in the LED Indication - Discrete range at ChipApex. The manufacturer field lists Everlight Electronics Co Ltd. Its product description is LED. Review the specifications below when checking this part for your BOM.
The Everlight Electronics Co Ltd 204YD-A-L is a single-color visible light emitting diode designed for indication applications. It features a brilliant yellow emission with a peak wavelength of 591 nm housed in a compact 1.4 mm rectangular surface-mount package. The device utilizes a water clear lens to optimize light transmission and operates within a standard temperature range of -40 °C to 85 °C. With a maximum forward current rating of 25 mA, it provides reliable performance for electronic circuit status monitoring.
Verify the specific ordering suffix against official Everlight documentation to ensure correct binning and packaging configuration. Confirm that the component meets RoHS compliance requirements for your target market regulations. Check for any recent lifecycle updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Select this component when a low-profile surface-mount yellow LED is required for space-constrained designs. Ensure the driving circuit supports the specified 25 mA maximum forward current limit. Consider the 60-degree viewing angle characteristics for visibility requirements in the intended application environment.
This part belongs to Everlight's discrete LED indication series, offering standardized surface-mount solutions for general-purpose signaling. The 1.4 mm package size allows for dense PCB layouts compared to traditional through-hole alternatives. It serves as a direct replacement for similar small-footprint yellow LEDs in existing hardware designs.
Cross-reference pinout compatibility and thermal resistance values when substituting with other manufacturers' 1.4 mm SMD yellow LEDs. Verify that alternative components meet the same 591 nm peak wavelength specification for consistent color appearance.
