Procurement Notes

Verify RoHS compliance status carefully as sources indicate conflicting information regarding compatibility. Confirm current manufacturing availability and lead times directly with the supplier or authorized distributors, as stock levels may vary significantly across regions and channels.

Selection Notes

Select this component for designs requiring standard 10/100/1000 Base-T isolation. Ensure PCB footprint matches the specified SMD dimensions. Consider thermal management requirements within the -40°C to +85°C operating range during system integration.

Part Context

This part belongs to the iNRCORE audio and signal transformers category, specifically under pulse transformers. It serves as a critical isolation component in high-speed digital communication circuits, distinguishing itself from general-purpose audio transformers through its specific impedance and bandwidth characteristics for data transmission.

Replacement Considerations

R5033NL is a documented substitute offering similar 350µH inductance and 1000Base-T support. Verify pinout compatibility and physical package dimensions before substitution to ensure proper board fit and electrical performance.
