Substitute Part Grouping Explanation

Substitute parts for the BLC2021-BK-USB-FB are determined by strict equivalence across the following critical parameters: manufacturer (Matrix Orbital), number of characters (40), display format (20 x 2), display type (LCD - Monochrome), character size (5.55mm H x 3.20mm W), physical dimensions (116.00mm x 37.00mm x 28.98mm), viewing area (83.00mm L x 18.60mm W), supply voltage (5V), and interface type (USB). All substitute parts maintain identical electrical and mechanical specifications. The primary differentiator among substitute parts is text color, which varies between Blue (BLC2021-BK-USB-FB), Amber (BLC2021-BK-USB-FA), Green (BLC2021-BK-USB-FG), Yellow (BLC2021-BK-USB-IY), and Red (BLC2021-BK-USB-R). Text color selection does not affect functional compatibility or electrical performance and is determined by application display requirements.
