Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing relocation notices may affect production details. Confirm that the required lead time aligns with project schedules, as standard delivery periods can vary. Ensure the through-hole pin configuration matches the target PCB footprint. Check for any RoHS compliance updates or environmental declarations relevant to the specific batch before finalizing procurement.

Selection Notes

Select this model when a small form factor is required alongside strict isolation requirements. The multi-tapped primary allows operation across different international mains voltages without changing components. Consider the 2.5VA power limit to ensure the load does not exceed thermal ratings. The through-hole termination style is suitable for manual assembly or wave soldering processes where surface mount options are not preferred.

Part Context

This component belongs to the Signal Transformer 14A series, which specializes in transformers for low-power applications. The series emphasizes high isolation capabilities and robust creepage distances. These units are typically utilized in scenarios where space constraints are minimal but electrical safety and reliable voltage transformation are paramount. The design focuses on providing stable performance across varying line conditions.

Replacement Considerations

Direct substitutes within the same series include models like the 14A-2.5R-20, which shares similar electrical characteristics but may differ in physical dimensions. Verify that any replacement maintains the 4000Vrms isolation rating and compatible terminal pitch. Cross-reference the primary winding configurations to ensure voltage compatibility with the existing circuit design.
