1. Manufacturer & Production Process: The components are sourced from Abracon and TGS, respectively. Core manufacturing processes, including the ceramic powder formulation, electrode materials, and internal structure, may differ. This could result in minor deviations in frequency stability and aging characteristics under extreme temperature conditions or during prolonged operation. 2. Price & Supply Chain: The TGS part is priced approximately 25% lower. This cost advantage primarily stems from differences in brand premium, production costs, and supply chain strategies. Selection requires a trade-off between this cost benefit and the established trust in a supplier's quality management system and supply stability. 3. Undisclosed Performance Parameters: Certain parameters not explicitly detailed in the datasheets—such as startup time, sensitivity to drive level, and resistance to shock and vibration—may vary between manufacturers. These differences could become significant in demanding industrial or high-vibration environments.
