Arrays, Signal Transformers Procurement Notes

Verify component status as the original CTX5-2 part number is officially discontinued by Eaton Electronics Division. Confirm availability through authorized distributors for remaining stock or transition to the designated direct replacement CTX5-2-R. Ensure datasheet revisions match specific production batches to validate RoHS compliance and pin compatibility before finalizing procurement orders.

Arrays, Signal Transformers Selection Notes

Select this component for designs requiring coupled inductors with specific parallel-series inductance ratios. Verify that the 3 A parallel current rating meets system load requirements. Check footprint dimensions against PCB layout constraints. Consider the discontinuation status when planning long-term manufacturing support and supply chain stability for new productions.

Arrays, Signal Transformers Part Context

This component belongs to the OCTA-PAC family of toroidal power inductors manufactured by Eaton Electronics Division. These devices are designed for high-efficiency power conversion applications. The CTX5-2 specifically utilizes an amorphous metal core, distinguishing it from iron powder alternatives in other series like LCPI. It serves as a specialized passive component for managing electromagnetic interference in compact electronic systems.

Arrays, Signal Transformers Replacement Considerations

The official direct replacement for the discontinued CTX5-2 is the CTX5-2-R. This updated part maintains identical electrical characteristics and form factor, ensuring seamless integration into existing designs without requiring schematic or layout modifications.
