Procurement Notes
Verify availability status carefully as this component is marked as obsolete or discontinued by Bourns Inc. Sourcing may require checking secondary market distributors or legacy stock holders. Confirm RoHS compliance details, as some records indicate non-compliance. Ensure the specific revision matches design requirements before procurement.
Selection Notes
Select this component only if legacy compatibility is required for existing designs utilizing the J.W. Miller 7000 series. Evaluate alternative modern coupled inductors if new development is underway. Verify that the unshielded nature meets electromagnetic compatibility standards for the target application environment.
Part Context
This component belongs to the Bourns J.W. Miller line of passive components, specifically within the coupled inductor category. It represents a traditional through-hole technology solution, distinct from surface-mount alternatives. The product line focuses on reliable performance for industrial and commercial electronic assemblies.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements must be identified through engineering equivalence analysis rather than official cross-reference lists.
