CMR04F161JPDP Equivalent & Substitute Parts
Part Overview
The CMR04F161JPDP is a 160 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance across wide temperature ranges. Mica capacitors are selected for applications demanding high reliability, low loss, and excellent frequency stability. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory levels require diversification across equivalent product variants.
