CD10CD030DO3 Equivalent & Substitute Parts Reference

Part Overview

The CD10CD030DO3 is a 3 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 values with tight tolerance specifications. Mica dielectric capacitors are selected for applications demanding high stability, low loss, and reliable performance across extended temperature ranges from -55°C to 125°C. Identifying equivalent substitute parts becomes necessary when managing inventory constraints, addressing supply chain variations, or accommodating different compliance requirements across manufacturing batches.

Substitute Part Grouping Explanation

Substitute parts for the CD10CD030DO3 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Capacitance: 3 pF
• Tolerance: ±0.5 pF
• Voltage Rating: 500 V
• Dielectric Material: Mica

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.142" (3.60 mm)
• Physical Dimensions: 0.360" L x 0.189" W (9.15 mm x 4.80 mm)
• Maximum Seated Height: 0.331" (8.40 mm)

Environmental Parameters (Must Match Exactly):

• Operating Temperature Range: -55°C to 125°C

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in compliance certifications (RoHS status, REACH classification) do not affect electrical or mechanical substitutability but may influence procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The CD10CD030DO3F serves as a direct parametric equivalent to the CD10CD030DO3. Both components are manufactured by Cornell Dubilier Electronics within the CD10 series and share identical electrical specifications, mechanical dimensions, and environmental operating parameters.

Selection Basis:

The primary distinction between these parts lies in regulatory compliance status. The CD10CD030DO3F achieves ROHS3 compliance and REACH unaffected status, whereas the CD10CD030DO3 is classified as RoHS non-compliant and REACH affected. This difference reflects manufacturing process variations or material sourcing changes within the same product line.

For applications subject to RoHS3 or REACH regulatory requirements, the CD10CD030DO3F is the appropriate selection. For applications without such regulatory constraints, either part satisfies the electrical and mechanical requirements identically. Both parts maintain active product status and are suitable for general-purpose applications requiring 3 pF capacitance at 500 V with ±0.5 pF tolerance.

Frequently Asked Questions (FAQ)

Q: Can CD10CD030DO3F replace CD10CD030DO3 in existing designs?

A: Yes. The CD10CD030DO3F is a direct parametric equivalent. All electrical specifications (capacitance, tolerance, voltage rating), mechanical dimensions (lead spacing, package type, physical size), and environmental operating parameters are identical. Direct substitution in PCB layouts and circuit designs is supported without modification.

Q: What is the difference between CD10CD030DO3 and CD10CD030DO3F?

A: The parts are electrically and mechanically identical. The difference is regulatory compliance: CD10CD030DO3F is ROHS3 compliant and REACH unaffected, while CD10CD030DO3 is RoHS non-compliant and REACH affected. This reflects different manufacturing batches or material sourcing within the same product line.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory shows 923 pieces of CD10CD030DO3 and 981 pieces of CD10CD030DO3F in stock. Selection may be influenced by availability and supply chain requirements, in addition to regulatory compliance needs.

Q: Does the radial package configuration differ between these parts?

A: No. Both parts use identical radial through-hole packaging with 0.142" (3.60 mm) lead spacing, 0.360" L x 0.189" W physical dimensions, and 0.331" maximum seated height. PCB footprints and mounting procedures are identical.

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

A: Both parts are specified for general-purpose applications. Mica dielectric capacitors in this value range (3 pF) are typically used in RF and microwave circuits where stability and low loss are required. Specific frequency performance characteristics are not provided in the parametric data and should be confirmed through detailed application analysis.

Q: What is the tolerance significance for 3 pF capacitors?

A: The ±0.5 pF tolerance represents a tolerance band of ±16.7% relative to the nominal 3 pF value. This tight tolerance is characteristic of mica capacitors and is suitable for precision applications where capacitance stability is critical. Both parts maintain identical tolerance specifications.
