Procurement Notes

Verify the exact datasheet version from Signal Transformer to confirm current manufacturing status and pinout configurations. Ensure that the 2.5 VA rating meets the load requirements of the target application. Check for any recent product change notifications regarding material composition or regulatory compliance updates before finalizing procurement orders.

Selection Notes

Select this model when a compact, board-mount solution is required for stepping down standard line voltages to 24 VDC after rectification. Consider the physical footprint and lead spacing for PCB layout constraints. Evaluate thermal performance under maximum load conditions to ensure reliable operation within the intended operating temperature range without additional cooling measures.

Part Context

This component belongs to the CL2 series of laminated transformers, which are engineered for general-purpose power transformation in space-constrained environments. The series offers various voltage combinations and power ratings to suit different electronic design needs while maintaining consistent form factors for easy interchangeability within compatible system architectures.

Replacement Considerations

Direct substitutes must match the 2.5 VA rating, 24 V secondary output, and dual primary input specifications. Verify mechanical dimensions and terminal pitch compatibility to ensure seamless integration into existing PCB layouts without redesigning the mounting structure or trace routing.
