LED Display/7-segment Display
The KW3-307ARD is a 0.31-inch (8 mm) red, common-anode, 3-digit 7-segment LED display, commonly referred to as an LED numeric display. This part was developed as a direct replacement for ROHM’s discontinued LB-303VA, ensuring drop-in compatibility without design changes.
With red segments on a black surface, the display provides clear and reliable performance for digital readouts. It follows industry-standard package dimensions and pin configurations for seamless integration into existing designs.
The KW3-307 series is available in both common-anode and common-cathode versions, with multiple color options such as red, green, blue, and orange to meet diverse application needs. The KW3-307ARD, as the red common-anode version, includes a right-hand decimal point and is ideal for indoor LED numeric displays in industrial equipment and household appliances.
