The LuckyLight KD1-321ASD is a 0.32-inch (8.00 mm) single-digit, red, common-anode Through-Hole 7-Segment LED Display designed for through-hole PCB and socket mounting. This LED Numeric Display features a black surface with red segments and a dominant wavelength of 640 nm, providing clear on/off contrast and uniform segment illumination.

With a standard 2.0 mm pin pitch for straightforward PCB integration, the display allows designers to select the drive current to balance brightness and power consumption within datasheet limits. The series offers both common-anode and common-cathode configurations, with custom emitting colors and package finishes available upon request.

ROHM LA-301VB Replacement: For legacy equipment facing component obsolescence, the KD1-321ASD serves as a direct, pin-compatible drop-in alternative to the discontinued ROHM LA-301VB—offering identical 8.00 mm character height, mechanical footprint, and pinout assignment. Optional gray-surface finishes are available upon request.
