CD19FD101JO3 Equivalent & Substitute Parts

Part Overview

The CD19FD101JO3 is a 100 pF mica capacitor rated for 500 V operation in a radial through-hole configuration, 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 applications demanding low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Identification of equivalent substitute parts becomes necessary when managing inventory constraints, addressing supply chain variations, or accommodating different compliance certifications while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution of the CD19FD101JO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD19FD101JO3F maintains identical specifications in the following key areas:

• Capacitance Value: 100 pF (exact match)
• Tolerance: ±5% (exact match)
• Voltage Rating: 500 V (exact match)
• Dielectric Material: Mica (exact match)
• Operating Temperature Range: -55°C to 125°C (exact match)
• Mounting Configuration: Through Hole, Radial (exact match)
• Physical Dimensions: 0.642" L x 0.189" W, 0.500" height seated (exact match)
• Lead Spacing: 0.343" (8.70 mm) (exact match)
• Series Classification: CD19 (exact match)
• Application Category: General Purpose (exact match)

The substitute part is derived from the same manufacturer (Cornell Dubilier Electronics) and series, ensuring functional and mechanical interchangeability. The primary distinction between the main part and substitute relates to compliance certifications and regulatory status, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD101JO3F serves as a direct electrical and mechanical substitute for the CD19FD101JO3. Both parts are active products from Cornell Dubilier Electronics within the CD19 series and deliver identical performance across all functional parameters.

Compliance Considerations: The primary distinction between these parts is regulatory compliance status. The CD19FD101JO3F achieves ROHS3 compliance and REACH unaffected status, whereas the CD19FD101JO3 is RoHS non-compliant and REACH affected. Selection between these parts should be based on project-specific compliance requirements and regulatory jurisdiction. Applications subject to RoHS3 or REACH restrictions should utilize the CD19FD101JO3F variant.

Inventory and Availability: The CD19FD101JO3 maintains 998 pieces in stock, while the CD19FD101JO3F maintains 774 pieces in stock. Both variants are available as new original components in bulk packaging.

Functional Interchangeability: No electrical performance differences exist between these parts. Both deliver 100 pF capacitance at ±5% tolerance, 500 V rated voltage, and identical thermal and mechanical characteristics. PCB layout, lead spacing, and component footprint requirements are identical.

Frequently Asked Questions (FAQ)

Q: Can CD19FD101JO3F be used as a direct replacement for CD19FD101JO3 in existing designs?
