AISC-1812H-100K-T Equivalent & Substitute Parts Reference

Part Overview

The Abracon LLC AISC-1812H-100K-T is a fixed inductor featuring a 10 µH inductance, 650 mA current rating, and a maximum 350mOhm DC resistance in a 1812 (4532 Metric) surface-mount package. This device employs an unshielded ferrite drum core and is compliant with ROHS3. The product is classified as obsolete, making identification of electrically and mechanically equivalent substitute models necessary to ensure compatible design integration and sustained product lifecycle in applications where the original part is unavailable.

Substitute Part Grouping Explanation

Substitution is defined strictly by key electrical and mechanical parameters: inductance value, tolerance, current rating, maximum DC resistance, shielding configuration, core material, mounting type, package/size, test frequency, frequency self-resonance, and environmental ratings. The validity of substitution requires exact or better alignment of these parameters with the original part (AISC-1812H-100K-T) to maintain functional equivalence and ensure compatible fit and performance within the end application. Only parts matching these parameters are listed as substitutes.
