Substitute Part Grouping Explanation

Substitution of the 1111Y5000470FUT is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 47 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500V (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Package designation: 1111 (2828 Metric) (exact match required)
• Physical dimensions: 0.110" L x 0.110" W x 0.070" max thickness (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The substitute part 1111Y5000470FQT meets all these criteria and is manufactured by the same supplier (Knowles Syfer) within the same product series (FlexiCap™).

Parameter Comparison
