Equivalent & Substitute Parts for 05083C102MAT2A

Part Overview

The 05083C102MAT2A is a surface mount multilayer ceramic capacitor (MLCC) manufactured by KYOCERA AVX. It features a capacitance of 1000 pF, X7R temperature coefficient, 25V rated voltage, and a 0508 (1220 Metric) reverse geometry package. The part is ROHS3 compliant, REACH unaffected, and has an unlimited MSL. The product is listed as active and is suitable for bypass and decoupling applications. Alternative models are necessary to address inventory management, ensure supply chain stability, and meet system requirements in cases of allocation or extended lead time.
