CD19FD502JO3 Mica Capacitor 5000 pF 500V Radial

Part Overview

The CD19FD502JO3 is a 5000 pF mica capacitor rated for 500 V with radial through-hole mounting. Manufactured by Cornell Dubilier Electronics (CDE), this component is classified as Active and suitable for general-purpose applications requiring stable capacitance and high voltage performance. Mica dielectric capacitors are selected for circuits demanding low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Alternative part numbers may be required due to inventory availability, compliance requirements, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FD502JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (5000 pF), tolerance (±5%), and rated voltage (500 V) must remain identical. The mica dielectric material is a defining characteristic and cannot be substituted with alternative dielectric types.

Mechanical Parameters: Mounting type (Through Hole), package configuration (Radial), and lead spacing (0.343" / 8.70 mm) must match to ensure PCB compatibility and assembly feasibility.

Environmental Parameters: Operating temperature range (-55°C to 125°C) establishes the thermal performance envelope and must be maintained.

Series Designation: Parts within the CD19 series maintain consistent construction and performance characteristics.

The substitute part CD19FD502JO3F meets all electrical, mechanical, and environmental specifications. The primary distinction between the main part and its substitute relates to compliance certifications and inventory status.

Parameter Comparison

Engineering Selection Recommendations

Both CD19FD502JO3 and CD19FD502JO3F are functionally equivalent and electrically interchangeable for applications requiring 5000 pF mica capacitors at 500 V with radial through-hole mounting.

Compliance Considerations: The CD19FD502JO3F is ROHS3 compliant and REACH unaffected, making it the appropriate selection for applications subject to European Union environmental directives or customer specifications requiring RoHS compliance. The CD19FD502JO3 is RoHS non-compliant and REACH affected, suitable for applications without such regulatory constraints.

Inventory and Availability: Both parts are Active products with adequate stock levels. The CD19FD502JO3F maintains higher inventory (1109 pcs) compared to the CD19FD502JO3 (992 pcs).

Application Suitability: Selection between these parts should be driven by compliance requirements of the end application and supply chain specifications rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CD19FD502JO3F replace CD19FD502JO3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The CD19FD502JO3F is suitable as a direct substitute provided that RoHS compliance is acceptable or required by the application.

Q: What is the difference between CD19FD502JO3 and CD19FD502JO3F?

A: The parts are identical in electrical specifications, capacitance value, voltage rating, dielectric material, and physical dimensions. The primary differences are RoHS compliance status (CD19FD502JO3F is ROHS3 compliant; CD19FD502JO3 is non-compliant) and REACH regulatory status (CD19FD502JO3F is unaffected; CD19FD502JO3 is affected).

Q: Are these capacitors suitable for high-frequency applications?

A: Mica dielectric capacitors in the CD19 series are designed for general-purpose applications. Frequency performance characteristics are not provided in the specification parameters.

Q: What is the lead spacing tolerance?

A: Lead spacing is specified as 0.343" (8.70 mm) for both parts. Tolerance information for lead spacing is not provided in the available parameters.

Q: Can these capacitors be used in surface-mount applications?

A: No. Both CD19FD502JO3 and CD19FD502JO3F are through-hole radial components and are not suitable for surface-mount assembly.

Q: What is the moisture sensitivity level?

A: Moisture Sensitivity Level (MSL) is listed as Not Applicable for both parts, indicating these components do not require moisture-controlled storage or handling.
