Substitute Part Grouping Explanation

Substitution of the 1111Y5000200GUT is determined by strict equivalence across the following parameters:

• Capacitance value: 20 pF
• Tolerance: ±2%
• Voltage rating: 500V
• Temperature coefficient: C0G/NP0 (1B)
• Operating temperature range: -55°C to 125°C
• Package designation: 1111 (2828 Metric)
• Mounting configuration: Surface Mount, MLCC
• Regulatory compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute part 1111Y5000200GQT meets all these criteria and is manufactured by the same supplier, Knowles Syfer, within the same FlexiCap™ series. The primary distinction is product status: the original part is obsolete while the substitute is active.
