Fixed Inductors Procurement Notes

This component is officially discontinued and no longer manufactured by Samsung Electro-Mechanics. Procurement must rely on third-party distributors for remaining stock or authorized substitute parts. Verify lot dates and authenticity carefully when sourcing from secondary markets due to end-of-life status.

Fixed Inductors Selection Notes

Engineers should evaluate alternative components from the same manufacturer series or cross-reference compatible shielded inductors with identical 2.2 µH values and 0805 footprints. Ensure replacement parts meet the original 800 mA current rating and 250 mΩ DCR specifications to maintain circuit performance integrity.

Fixed Inductors Part Context

The CIG21C2R2MNE belongs to the CIG21 series of chip inductors designed for compact electronic applications. As a multilayer type, it offers reliable performance in space-constrained designs. The series was widely used in consumer electronics before being phased out in favor of newer manufacturing technologies.

Fixed Inductors Replacement Considerations

Public confirmed substitutes include AIML-0805HC-2R2M-T, ASMPH-0805-2R2M-T, LQM21PN2R2MCAD, and LQM21PN2R2MCHD. These alternatives provide similar electrical characteristics and package dimensions for direct board-level replacement.
