CD19FD472JO3 Mica Capacitor - Equivalent & Substitute Parts

Part Overview

The CD19FD472JO3 is a 4700 pF mica capacitor rated for 500 V with ±5% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is actively produced and designed for general-purpose applications requiring stable capacitance and high voltage performance. Alternative parts become necessary when addressing specific compliance requirements, managing inventory constraints, or accommodating design variations across manufacturing series while maintaining electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD472JO3 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 4700 pF (exact match required)
• Voltage Rating: 500 V (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric Material: Mica (exact match required)
• Lead Spacing: 0.343" (8.70 mm) (exact match required)
• Physical Dimensions: 0.701" L x 0.350" W (17.80 mm x 8.90 mm) (exact match required)
• Maximum Seated Height: 0.579" (14.70 mm) (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The identified substitutes meet all electrical and mechanical requirements for direct replacement. Variations in manufacturing series designation (CD19 versus CM06), compliance certifications, and packaging do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts are actively produced and available from Cornell Dubilier Electronics. Selection between the CD19FD472JO3, CD19FD472JO3F, and CM06FD472JO3 depends on compliance and regulatory requirements:

CD19FD472JO3F is the recommended selection for applications requiring RoHS3 compliance and REACH Unaffected status. This variant maintains identical electrical and mechanical specifications while addressing modern environmental regulations.

CD19FD472JO3 and CM06FD472JO3 are functionally equivalent alternatives suitable for applications where RoHS3 compliance is not mandated. Both maintain full electrical performance and are available in adequate inventory quantities.

Compliance status differences reflect manufacturing process updates and do not affect component performance, reliability, or interchangeability within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can CD19FD472JO3F replace CD19FD472JO3 in existing designs? A: Yes. The CD19FD472JO3F is a direct functional equivalent. It maintains identical capacitance, voltage rating, tolerance, dielectric material, physical dimensions, lead spacing, and operating temperature range. The primary difference is RoHS3 compliance status.

Q: What is the difference between CD19 and CM06 series designations? A: Both series use identical electrical specifications and physical packages for this part number. The CM06 series is an alternative manufacturing line from Cornell Dubilier Electronics. Lead spacing, dimensions, and all electrical characteristics are equivalent.

Q: Are there any compliance considerations when substituting these parts? A: Yes. Applications requiring RoHS3 compliance and REACH Unaffected certification must use CD19FD472JO3F. Applications with no such compliance requirements can use any of the three equivalents. All parts carry EAR99 classification and fall under HTSUS code 8532.29.0020.

Q: Do these mica capacitors have identical moisture sensitivity levels? A: CD19FD472JO3 and CD19FD472JO3F are not applicable for moisture sensitivity classification. CM06FD472JO3 carries MSL rating 1 (Unlimited), which does not restrict handling or storage procedures.

Q: Can I use CD19FD472JO3 in a design originally specified for CM06FD472JO3? A: Yes. All three part numbers are mechanically and electrically equivalent. Footprint compatibility, lead spacing, and mounted height are identical.
