CD19FD431GO3 Equivalent & Substitute Parts

Part Overview

The CD19FD431GO3 is a 430 pF mica capacitor rated for 500 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as a general-purpose mica capacitor with ±2% tolerance and operates across the temperature range of -55°C to 125°C. The part is currently in active production status with 783 units available in inventory.

Mica capacitors in this specification are used in applications requiring stable capacitance values, low loss, and high voltage performance. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific application requirements for different series designations within the same electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the CD19FD431GO3 is based on strict equivalence of the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 430 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Mechanical Equivalence Criteria:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.343" / 8.70 mm (exact match required)
• Physical dimensions: 0.642" L × 0.201" W / 16.30 mm × 5.10 mm (exact match required)
• Maximum seated height: 0.512" / 13.00 mm (exact match required)

The substitute part CM06FD431GO3 meets all electrical and mechanical equivalence criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CD19FD431GO3 and CM06FD431GO3 are active production components manufactured by Cornell Dubilier Electronics and carry identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: Both parts maintain active production status, ensuring continued availability and consistent manufacturing standards.

Compliance and Certifications: Both parts share identical regulatory classifications:

• RoHS non-compliant status
• REACH Affected designation
• EAR99 export classification
• HTSUS code 8532.29.0020

Inventory Availability: The CD19FD431GO3 has 783 units in stock, while the CM06FD431GO3 has 668 units available. Selection may depend on immediate supply requirements.

Series Designation: The parts differ only in series designation (CD19 versus CM06), which reflects internal CDE product line organization but does not affect functional equivalence or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CM06FD431GO3 be used as a direct replacement for CD19FD431GO3?
