CD10FA331JO3 Equivalent & Substitute Parts

Part Overview

The CD10FA331JO3 is a 330 pF mica capacitor rated at 100 V with ±5% tolerance, manufactured by Cornell Dubilier Electronics (CDE) in the CD10 series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance and reliable performance across the operating temperature range of -55°C to 125°C. The part is currently active in production with 885 pieces available in inventory.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain optimization is required, or when design revisions necessitate component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD10FA331JO3 mica capacitor is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 100 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.142" (3.60mm) (exact match required)
• Physical Dimensions: 0.390" L x 0.220" W, Height 0.370" max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The substitute part CD10FA331JO3F meets all these criteria and is therefore classified as a parametric equivalent. The primary distinction between the main part and its substitute relates to compliance certifications and regulatory status, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

CD10FA331JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. This part number maintains active production status with adequate inventory availability.

CD10FA331JO3F is the appropriate selection for designs requiring ROHS3 compliance and REACH-unaffected material status. This variant is functionally and mechanically identical to the primary part number and carries higher inventory availability (1154 pieces versus 885 pieces). Selection of CD10FA331JO3F eliminates compliance-related design revisions while maintaining full electrical and mechanical compatibility.

Both part numbers are active products from Cornell Dubilier Electronics and are direct substitutes based on identical electrical specifications, physical dimensions, and performance characteristics across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CD10FA331JO3F be used as a direct replacement for CD10FA331JO3 in existing designs?

A: Yes. CD10FA331JO3F is a parametric equivalent with identical capacitance (330 pF), tolerance (±5%), voltage rating (100 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.142" / 3.60mm), physical dimensions (0.390" L x 0.220" W, 0.370" height max), and operating temperature range (-55°C to 125°C). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between CD10FA331JO3 and CD10FA331JO3F?

A: The primary differences are regulatory compliance certifications. CD10FA331JO3F is ROHS3 compliant and REACH unaffected, while CD10FA331JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Are there any physical or dimensional differences between these part numbers?

A: No. Both parts share identical physical dimensions: 0.390" length x 0.220" width, maximum seated height of 0.370", and lead spacing of 0.142" (3.60mm). They are mechanically interchangeable on printed circuit boards.

Q: Which part number should be selected for new designs?

A: CD10FA331JO3F is recommended for new designs due to ROHS3 compliance and REACH-unaffected status, which align with current regulatory requirements. Both parts are active in production; however, CD10FA331JO3F carries higher inventory availability.

Q: Do these capacitors require any special handling or storage considerations?

A: Both part numbers are mica dielectric capacitors with moisture sensitivity level not applicable. Standard electronic component storage practices apply. Refer to Cornell Dubilier Electronics technical documentation for detailed handling and storage specifications.

Q: Can these 330 pF mica capacitors be used in high-frequency applications?

A: Mica capacitors in the CD10 series are designed for general-purpose applications. Specific high-frequency performance characteristics are not provided in the parametric data. Consult Cornell Dubilier Electronics application notes for frequency-dependent performance details.
