Procurement Notes

This specific part number is officially classified as obsolete and is no longer manufactured by Delta Electronics/Components. Procurement should focus on identifying verified substitute components that meet the required electrical specifications and physical dimensions. Verify availability through authorized distributors or alternative manufacturer channels, as original stock is unavailable.

Selection Notes

When selecting a replacement, prioritize components with identical inductance values and current ratings to ensure circuit stability. The physical footprint must match the 1008 (2520 Metric) size to maintain compatibility with existing PCB layouts. Ensure the substitute component supports the required operating temperature range and maintains similar Q-factor characteristics for effective performance in high-frequency applications.

Part Context

The 1008HS series represents a line of wire-wound chip inductors designed for general electronic applications. These components are characterized by their robust ferrite core construction and unshielded topology, which allows for efficient magnetic field distribution. The series caters to various inductance values while maintaining consistent mechanical dimensions for standardized manufacturing processes.

Replacement Considerations

Publicly confirmed substitute part numbers include NLV25T-R68J-N. Verify that the substitute matches the 0.68 µH inductance, 800 mA current rating, and 1008 package size before integration.
