Procurement Notes

Verify the specific manufacturer part number against official iNRCORE documentation to ensure compatibility with MIL-STD-1553 standards. Confirm that the surface mount package dimensions align with your PCB layout constraints. Check for any recent product change notifications or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing for strict MIL-STD-1553 compliance in surface-mount environments. Consider the thermal operating range and physical dimensions relative to other available interface transformers. Ensure that the DC resistance and isolation characteristics meet the specific signal integrity requirements of the target bus architecture.

Part Context

This part belongs to the iNRCORE family of pulse transformers and interface modules. It is distinct from similar models like the DFLC1553-3 or FLC1553-5 by its specific winding configuration and package style. The series includes various variants tailored for different impedance ratios and mounting requirements within the same industrial and military application scope.

Replacement Considerations

Direct substitutes may include other MIL-STD-1553 interface transformers from iNRCORE such as the FLC1553-5, provided the pinout and electrical parameters match. Cross-reference with competitors offering equivalent MIL-STD-1553 compliant surface-mount solutions if supply chain constraints exist.
