For a direct 2 A drop-in, the 5SY5102-6CC12 is the correct railway-rated variant; the 5SY4 series lacks the railway designation and vibration rating. No rewiring needed for the same DIN footprint, but verify the DC voltage rating and ambient derating against your application."},{"question":"What compliance documentation does Siemens provide for 5SY5102-6CC12?","answer":"The product is halogen-free and silicon-free, which supports RoHS and REACH compliance.
