Key Parameters

Substitute Part Grouping Explanation

Substitution of the RF03N0R2B250CT is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Capacitance value of 0.2 pF with tolerance of ±0.1pF, rated voltage of 25V, and C0G/NP0 temperature coefficient must be identical to ensure circuit performance and stability across the operating temperature range of -55°C to 125°C.

Mechanical Compatibility: Package designation of 0201 (0603 Metric) with physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm) must match to ensure proper placement on printed circuit boards and compatibility with automated assembly equipment.

Compliance & Certifications: ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) classification must be maintained to satisfy regulatory requirements and handling specifications.

Application Alignment: RF, microwave, and high-frequency application suitability with surface-mount MLCC technology must be preserved.

The identified substitute part CBR02C208B3GAC from KEMET meets all these criteria and is classified as a parametric equivalent.
