Procurement Notes

This component is officially discontinued and no longer manufactured by Eaton Electronics Division. Verification of availability should focus on surplus stock or authorized distributors holding remaining inventory. Ensure the specific suffix matches requirements as ordering variations may exist within the series. Confirm RoHS compliance status through official documentation before integration into new designs.

Selection Notes

Engineers selecting this part must account for its discontinued status when planning long-term production runs. The specific electrical parameters, including the 1340V secondary output and 6W power rating, define its suitability for CCFL applications. Alternative components from the same family series should be evaluated for pin compatibility and electrical equivalence to ensure seamless replacement in existing circuit architectures.

Part Context

The CTX210609-R belongs to the CTX21 series of specialty transformers designed specifically for CCFL applications. This series includes related models such as CTX210600-R, CTX210602-R, and CTX210605-R, which share similar form factors but differ in electrical specifications. The product line was produced by Eaton's Electronics Division, focusing on compact, high-efficiency magnetic components for display backlighting solutions.

Replacement Considerations

Public confirmed substitute part numbers include CTX210600-R, CTX210602-R, CTX210603-R, CTX210605-R, CTX210607-R, CTX210611-R, and CTX210609-R variants within the same discontinued series. Cross-referencing datasheets is essential to verify voltage and current ratings match the original design requirements.
