Pulse Transformers Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus stock or secondary market sources rather than direct manufacturing orders. Confirm RoHS non-compliance status if environmental regulations apply to the target assembly. Check for specific PCN documentation regarding any final time buy options before discontinuation.

Pulse Transformers Selection Notes

Select this part only for legacy 10Base-T designs requiring SMD pulse transformers. Ensure the application does not require Power over Ethernet functionality, as this model is NonPoE. Verify that the physical footprint matches the PCB layout constraints given its specific dimensional requirements. Consider replacement alternatives if new production is required due to the obsolete lifecycle status.

Pulse Transformers Part Context

Pulse Electronics manufactures magnetic components for signal and power applications. The ST7010T belongs to their portfolio of Ethernet transformers. This specific model addresses historical networking standards. It is distinct from modern high-speed Ethernet solutions. The product line focuses on reliable signal isolation for copper-based networks.

Pulse Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, no direct official replacements are listed. Engineers must evaluate generic 10Base-T SMD transformers or newer series from the manufacturer for compatibility.
