Substitute Part Grouping Explanation

Substitution for the GRM1885C1H9R9DA01D is determined by strict equivalence across the following critical parameters:

Capacitance value of 9.9 pF with tolerance of ±0.5pF ensures functional compatibility in the circuit. Voltage rating of 50V or higher maintains safety margins. Temperature coefficient C0G/NP0 provides stable capacitance across the operating temperature range of -55°C to 125°C. Package specification 0603 (1608 Metric) with surface mount MLCC mounting type ensures mechanical and assembly compatibility. Physical dimensions and thickness must match to prevent PCB layout conflicts. Moisture sensitivity level 1 and RoHS3 compliance are required for environmental and regulatory compatibility.

The substitute part CBR06C999D5GAC from KEMET meets all these criteria while offering enhanced performance characteristics suitable for RF and high-frequency applications.
