Part Numbering Rules
Hongcheng part numbers start with "HC-" (Hongcheng Optoelectronics brand code). The digits in the middle section indicate the package size (e.g. 10 = 10mm, 8 = 8mm through-hole; 0603, 0805 etc. for SMD packages). Letter groups such as "RGB" or "RG" indicate the emitting color (RGB full-color, RG bi-color, etc.). Trailing letters are detail codes for common cathode/anode, lens type (clear/diffused) and lead forming — please refer to each model's datasheet PDF, or contact sales at 139 2571 4318 (WeChat available) for the exact mapping.
