19-21SURC/S530-A2/4T 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 Everlight 19-21SURC/S530-A2/4T is a single-color surface-mount LED featuring a hyper red lens with a peak wavelength of 624 nm. It delivers a luminous intensity of 482 mcd at a forward current of 20 mA and a forward voltage of 2 V. The component has a power rating of 60 mW and utilizes a water-clear dome-shaped lens measuring 1.8 mm. Designed for SMD/SMT installation, it operates within a temperature range suitable for standard electronic assemblies.
Verify the specific suffix (e.g., /4T) against the manufacturer's latest datasheet to confirm packaging and binning details. Ensure compatibility with your reflow soldering profile and moisture sensitivity level requirements before finalizing procurement. Cross-reference the Mouser number 638-1921surcs530a2 for accurate distributor identification.
Select this component when a compact hyper red indicator is required with moderate brightness. The 1.8 mm size allows for high-density PCB layouts. Verify that the 624 nm wavelength meets visibility requirements for your specific application environment. Ensure the 20 mA forward current aligns with your circuit design constraints.
This part belongs to Everlight's 19-21 series of single-color LEDs, which are designed for general-purpose indication. The series offers various color options and lens types in a standardized small footprint. The /S530-A2 designation typically refers to specific binning or optical characteristics defined by the manufacturer.
Check for direct substitutes within the 19-21 series from Everlight or comparable SMD LEDs from other manufacturers offering similar 624 nm wavelength and 1.8 mm dimensions. Ensure pinout and thermal characteristics match.
