Is there a pin-compatible replacement for XL-1615SURUGC?

Yes, parts like XL-1615SURSYGC and P4-1615RGYTCA1-0.6T-C are pin-compatible for the Red and Green channels. However, they have different colors or additional dies, and electrical parameters like forward voltage may differ, necessitating circuit adjustments.

What risks should I check before replacing XL-1615SURUGC?

Key risks include color differences (e.g., Green vs. Yellow-Green), which affect visual output, and mismatched forward voltages, which require changes to series resistors to maintain correct brightness and prevent damage. Always verify the pinout on the datasheet.
