IMS05EV181K Equivalent & Substitute Parts

Part Overview

The IMS05EV181K is a 180 µH shielded molded inductor manufactured by Vishay Dale, designed for through-hole applications requiring moderate current handling at 135 mA with a maximum DC resistance of 4.4 Ohm. This component belongs to the IMS-5 series and is currently in stock with 854 pieces available as new original inventory.

Substitute parts are identified when they meet the critical electrical and mechanical parameters: inductance value, current rating, DC resistance, shielding type, and through-hole axial packaging. Finding equivalent components is necessary to ensure design flexibility, manage supply chain continuity, and maintain performance specifications across alternative sourcing options.
