Substitute Part Grouping Explanation

Substitute parts for the CM06FD681JO3 are classified as parametric equivalents based on identical electrical and mechanical specifications. The substitution logic is governed by the following critical parameters:

• Capacitance Value: 680 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Physical Dimensions: 0.650" L x 0.209" W with 0.343" lead spacing (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)

Substitute parts CD19FD681JO3 and CD19FD681JO3F belong to the CD19 series and maintain all core electrical and mechanical parameters identical to the CM06FD681JO3, enabling direct functional substitution in circuit designs and PCB layouts.
