PM4343.333NLT Equivalent & Substitute Parts

Part Overview

The PM4343.333NLT is a 33 µH shielded molded inductor manufactured by Pulse Electronics, designed for surface mount applications requiring high current handling and low DC resistance. This component is rated for 8 A continuous current with a maximum saturation current of 11 A and operates across the industrial temperature range of -40°C to 125°C. The part maintains Active product status and carries AEC-Q200 automotive-grade qualification, making it suitable for demanding applications in automotive, industrial, and telecommunications equipment.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical parameter envelope.
