CD19FD502JO3F Equivalent & Substitute Parts

Part Overview

The CD19FD502JO3F is a 5000 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as Active product status and is designed 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 performance across extended temperature ranges. Substitute parts are identified when inventory constraints, compliance requirements, or manufacturing discontinuation necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD502JO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 5000 pF
• Tolerance: ±5%
• Voltage rating: 500 V
• Dielectric material: Mica

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.343" (8.70mm)
• Physical dimensions: 0.709" L x 0.370" W (18.00mm x 9.40mm)
• Maximum seated height: 0.591" (15.00mm)

Environmental Parameters (Non-negotiable):

• Operating temperature range: -55°C ~ 125°C

Substitute parts must match all parameters listed above. Variations in compliance status (RoHS, REACH) or packaging format do not disqualify substitution when electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

CD19FD502JO3F (Primary Selection): This part is designated as ROHS3 Compliant and REACH Unaffected, making it suitable for applications subject to environmental compliance requirements in regulated markets. Current inventory of 1109 pieces supports immediate procurement. Selection of this variant is appropriate when compliance certifications are mandatory design constraints.

CD19FD502JO3 (Alternative Selection): This part is electrically and mechanically identical to the primary variant but carries RoHS non-compliant and REACH Affected designations. Current inventory of 992 pieces is available. This variant is suitable for applications where compliance certifications are not required or where legacy system maintenance permits use of non-compliant components. Both parts share identical electrical performance, mechanical fit, and thermal characteristics.

Selection between these two variants depends solely on compliance requirements of the end application and regulatory jurisdiction. No electrical or mechanical performance difference exists between the parts.

Frequently Asked Questions (FAQ)

Q: Can CD19FD502JO3 be used as a direct replacement for CD19FD502JO3F?

A: Yes. Both parts are electrically and mechanically identical. They share identical capacitance (5000 pF), tolerance (±5%), voltage rating (500 V), dielectric material (Mica), mounting configuration (Through Hole Radial), lead spacing (0.343" / 8.70mm), physical dimensions (0.709" L x 0.370" W), and operating temperature range (-55°C ~ 125°C). The only differences are compliance certifications (RoHS and REACH status). Selection depends on compliance requirements of the application.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in: capacitance value (5000 pF), tolerance (±5%), voltage rating (500 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.343" / 8.70mm), physical dimensions (0.709" L x 0.370" W / 18.00mm x 9.40mm), maximum seated height (0.591" / 15.00mm), and operating temperature range (-55°C ~ 125°C). Compliance status variations do not affect substitution eligibility when these parameters match.

Q: Are there any physical fit differences between CD19FD502JO3F and CD19FD502JO3?

A: No. Both parts have identical physical dimensions, lead spacing, and mounting characteristics. They are mechanically interchangeable in through-hole PCB applications with 0.343" (8.70mm) lead spacing.

Q: What is the difference between ROHS3 Compliant and RoHS non-compliant designations?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive 3 requirements, restricting specified hazardous materials. RoHS non-compliant indicates the part does not meet these restrictions. Selection depends on whether the end application or market jurisdiction requires RoHS compliance.

Q: What does REACH Unaffected versus REACH Affected mean?

A: REACH Unaffected indicates the part is not subject to Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulations. REACH Affected indicates the part is subject to REACH requirements. Selection depends on whether the application is subject to REACH regulatory jurisdiction.

Q: Can these parts be used interchangeably in legacy equipment?

A: Yes. Both parts are electrically and mechanically identical and can be used interchangeably in any application where the CD19 series 5000 pF 500 V mica capacitor is specified, regardless of compliance status differences.
