17-21/GPC-AK0M1B/4T is listed in the LED Indication - Discrete range at ChipApex. The manufacturer field lists Everlight Electronics Co Ltd. Its product description is LED SMD. Review the specifications below when checking this part for your BOM.
The 17-21/GPC-AK0M1B/4T is a single-color surface-mount LED manufactured by Everlight Electronics. It features a brilliant yellow emission with a peak wavelength of 557.5 to 567.5 nm. The component utilizes an 0805 (2012 Metric) package, measuring 2.00mm in length and 1.25mm in width, with a maximum height of 1.30mm. It operates within a temperature range of -40°C to +85°C and supports a forward current of 20 mA.
Verify the specific suffix configuration against official Everlight documentation to ensure correct color binning and packaging specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Cross-reference the part number with authorized distributors to validate authenticity and sourcing channels.
Select this component when a compact yellow indicator is required for PCB designs with limited space. The 0805 footprint offers a balance between size and thermal performance. Ensure the driving circuit can support the specified 20 mA forward current while maintaining operation within the -40°C to +85°C environmental range.
This LED belongs to the 17-21 series from Everlight, which focuses on small-form-factor indicators. The series provides various color options in standardized packages like 0805, allowing designers to maintain consistent board layouts while changing visual signals. It serves as a standard solution for general-purpose signaling in consumer and industrial electronics.
Direct substitutes include other 0805 yellow LEDs from Everlight such as the 17-21/GPC-AK0M1B/3T, provided the electrical characteristics and spectral output match the design requirements. Verify pin compatibility and thermal resistance before swapping.
