EK-23133-C01 Equivalent & Substitute Parts

Part Overview

The EK-23133-C01 is a 100 Hz to 10 kHz analog electret condenser microphone with omnidirectional pickup pattern manufactured by Knowles. This component delivers -53dB ±2dB sensitivity at 74dB SPL and operates at 1.3V with 50µA supply current. The part features solder pad termination in a compact rectangular form factor (5.56mm × 3.99mm × 2.26mm maximum height).

The EK-23133-C01 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.
