Procurement Notes

Verify component availability status as the ALAN-2202 is listed as obsolete by major distributors. Confirm end-of-life timelines and request last-time-buy information if immediate procurement is required. Ensure compatibility with existing PCB layouts before ordering final stock.

Selection Notes

Select this component for designs requiring robust LAN connectivity with integrated PoE functionality. The extended temperature range makes it suitable for industrial or outdoor deployments. Verify that the physical footprint and pinout align with the target PHY controller requirements.

Part Context

This part belongs to Abracon's LAN transformer series, specifically engineered for single-port Ethernet applications. It integrates magnetic components necessary for signal coupling and common-mode rejection in high-speed data transmission lines.

Replacement Considerations

Check for parametric equivalents from Abracon or other manufacturers. Ensure substitute parts match the 350µH inductance, 1500Vrms isolation, and 12.70x9.40x5.70mm form factor.
