Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations may exist. Confirm current availability status directly with authorized distributors or the manufacturer, as this component may be subject to lifecycle changes or discontinuation notices. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring specific AUI Ethernet isolation characteristics. The 100µH inductance and 16-SOIC package dimensions are critical constraints for board layout. Consider the 0°C to 70°C operating temperature range against environmental conditions. Verify that the 1:1 ratio meets the signal transmission requirements of the target application architecture.

Part Context

This component belongs to the Pulse Electronics LAN Transformers category, which includes various modules for different Ethernet standards. Unlike high-speed Gigabit or PoE transformers, this specific model targets the AUI standard. It differs from other Pulse models by its specific pinout, lower inductance value, and dedicated packaging for legacy or specialized industrial interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the specific nature of AUI Ethernet transformers and unique package constraints, direct replacements must be verified through official manufacturer cross-reference lists or engineering change notifications.
