Substitute Part Grouping Explanation

Substitution for the 1111Y5000100GUT is determined by strict equivalence across the following parameters:

• Capacitance value: 10 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
• Physical dimensions: 0.110" L × 0.110" W × 0.070" thickness

The substitute part 1111Y5000100GQT meets all these parameters and maintains identical electrical and mechanical specifications, differing only in product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 1111Y5000100GQT is the direct equivalent substitute for the obsolete 1111Y5000100GUT. Both components are manufactured by Knowles Syfer and share identical electrical specifications, mechanical dimensions, and compliance certifications. The substitute part maintains active product status, ensuring continued availability and manufacturing support. Both parts are ROHS3 compliant and carry identical export classification (EAR99) and tariff codes (8532.24.0020). Selection of the active substitute part eliminates obsolescence risk while preserving full functional and physical compatibility in RF, microwave, and high-frequency circuit applications.
