Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1111J5000360FUT is determined by the following critical parameters:

• Capacitance value: 36 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500V (minimum requirement)
• Temperature coefficient: C0G/NP0 (required for frequency stability)
• Package: 1111 (2828 Metric) (physical and electrical compatibility)
• Operating temperature range: -55°C ~ 125°C (functional envelope)
• Mounting type: Surface Mount, MLCC (assembly compatibility)

The substitute part 1111J5000360FQT meets all these criteria and is electrically and mechanically interchangeable with the original part.
