Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for the CD19FD911GO3 are determined by the following key electrical and mechanical parameters:

• Capacitance Value: 910 pF (exact match required)
• Tolerance: ±2% (substitutes must maintain this precision specification)
• Voltage Rating: 500 V (minimum requirement; higher ratings are acceptable)
• Dielectric Material: Mica (electrical performance characteristic)
• Operating Temperature Range: -55°C to 125°C (environmental operating envelope)
• Mounting Configuration: Through-hole radial mounting
• Lead Spacing: 0.343" (8.70 mm) (physical PCB compatibility requirement)
• Package Dimensions: 0.650" L × 0.209" W × 0.512" H max (spatial constraints)

The CD19FD911GO3F qualifies as a direct parametric equivalent based on matching all electrical specifications and physical form factors, with the distinction of improved compliance status.
