Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Procurement should account for end-of-life status when planning production runs. Verify current availability through authorized distributors as stock levels may vary. Ensure final design-in decisions consider the long-term supply chain implications associated with discontinued parts.

Selection Notes

Select this transformer specifically for systems utilizing Renesas FT series smart transceivers requiring FT-X3 compatibility. The dual-winding topology supports specific isolation requirements. Surface-mount packaging suits automated assembly processes. Confirm that the 3.3 V rating and 80 MHz operating frequency align with the target circuit specifications before integration.

Part Context

The 14255R-100 belongs to the specialty transformers category under Renesas Electronics. It serves as a dedicated interface component for Ethernet communication networks. The device facilitates signal coupling and isolation between transceiver ICs and physical layer connectors. Its design supports industrial screening levels for robust performance in demanding environments.

Replacement Considerations

No public confirmed substitute part numbers are available. Due to the scheduled obsolescence, alternative sourcing must rely on existing inventory or equivalent generic transformers meeting identical FT-X3 pinout and electrical specifications.
