Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalents maintain identical capacitance (3900 pF), tolerance (±10%), voltage rating (50V), and temperature coefficient (X7R) specifications. These parts are interchangeable without circuit redesign.

Tolerance Upgrades provide tighter tolerance (±5%) while maintaining all other electrical parameters. These parts offer improved capacitance accuracy for precision applications.

Voltage Upgrades increase the rated voltage to 100V while maintaining 3900 pF capacitance and X7R characteristics. These parts provide additional voltage margin in the same package.

All substitute parts share the following critical parameters with the main part:

Capacitance: 3900 pF
Temperature Coefficient: X7R
Package: 0603 (1608 Metric)
Mounting: Surface Mount, MLCC
