Substitute Part Grouping Explanation

Substitute parts for the CL21C151FBANNWC are classified into two categories based on electrical parameter compatibility:

Direct Equivalents maintain identical electrical specifications: 150 pF capacitance, ±1% tolerance, 50V rated voltage, C0G/NP0 temperature coefficient, and -55°C ~ 125°C operating temperature range. These parts are pin-compatible and functionally interchangeable within the same 0805 package footprint. Direct equivalents include C0805C151F5GAC7800 (KEMET) and KGM21BCG1H151FT (KYOCERA AVX).

Upgraded Substitutes increase the rated voltage to 100V while maintaining all other electrical parameters: 150 pF capacitance, ±1% tolerance, C0G/NP0 temperature coefficient, and -55°C ~ 125°C operating temperature range. These parts are physically compatible with the 0805 footprint and provide enhanced voltage margin for applications requiring higher voltage ratings. Upgraded substitutes include C0805C151F1GAC7800 (KEMET) and KGM21BCG2A151FT (KYOCERA AVX).

Substitution eligibility is determined by: capacitance value, tolerance, temperature coefficient, operating temperature range, package dimensions, and mounting type. Voltage rating may be increased without affecting circuit compatibility in applications with adequate design margin.
