AE14 Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The AE14 is a 1–14pF trimmer capacitor manufactured by Knowles Voltronics, designed for top adjustment through-hole mounting applications. This air-dielectric component operates at 125V rated voltage with a Q factor of 3000 @ 100MHz, suitable for general-purpose tuning and calibration circuits across industrial and commercial temperature ranges (-65°C to 125°C). The part maintains active product status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.
