CD15FD331GO3F Equivalent & Substitute Parts

Part Overview

The CD15FD331GO3F is a 330 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 when applications demand low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Substitute parts are identified when inventory constraints, compliance requirements, or series discontinuation necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the CD15FD331GO3F are identified based on strict electrical and mechanical parameter matching. The substitution logic requires that all substitute components maintain identical or superior specifications across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 330 pF (exact match required)
• Tolerance: ±2% (defines circuit performance boundaries)
• Voltage rating: 500 V (minimum requirement; higher ratings acceptable)
• Dielectric material: Mica (ensures electrical behavior consistency)
• Mounting type: Through Hole (assembly process compatibility)
• Package configuration: Radial (physical form factor)
• Lead spacing: 0.232" (5.90mm) (PCB footprint compatibility)
• Operating temperature range: -55°C to 125°C (environmental suitability)

The CM05FD331GO3 qualifies as a parametric equivalent because it satisfies all mandatory matching criteria. Both components are manufactured by Cornell Dubilier Electronics and share identical electrical specifications and physical dimensions. Differences in series designation (CD15 versus CM05), RoHS compliance status, and REACH classification do not affect functional substitutability but must be evaluated within the context of the end-application's regulatory requirements.

Engineering Selection Recommendations

CD15FD331GO3F Selection Criteria: The CD15FD331GO3F is the preferred component when RoHS3 compliance is a mandatory requirement for the end application. This part carries explicit ROHS3 Compliant certification and REACH Unaffected status, making it suitable for applications subject to European Union environmental directives or customer specifications requiring RoHS compliance documentation. The CD15 series designation indicates this component meets current regulatory standards.

CM05FD331GO3 Selection Criteria: The CM05FD331GO3 is functionally equivalent and electrically interchangeable with the CD15FD331GO3F. This substitute part is appropriate when RoHS compliance is not a contractual or regulatory requirement for the application. The CM05 series represents an earlier product line that does not carry RoHS3 certification. Selection of this substitute should be limited to applications where regulatory compliance documentation is not required or where legacy system compatibility necessitates use of non-compliant components. The higher inventory availability (1140 Pcs versus 762 Pcs) may provide supply chain advantages in high-volume procurement scenarios.

Compliance Considerations: Both components are classified as Active product status and share identical electrical and mechanical specifications. The decision between these parts must be driven by the application's regulatory environment and compliance obligations rather than by electrical performance factors.

Frequently Asked Questions (FAQ)

Q: Can CM05FD331GO3 be used as a direct replacement for CD15FD331GO3F in all applications?

A: The CM05FD331GO3 is electrically and mechanically interchangeable with the CD15FD331GO3F. Both components have identical capacitance (330 pF), tolerance (±2%), voltage rating (500 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.232"), and operating temperature range (-55°C to 125°C). Direct substitution is permissible from an electrical and physical compatibility standpoint. However, the CM05FD331GO3 is RoHS non-compliant and REACH Affected, whereas the CD15FD331GO3F is ROHS3 Compliant and REACH Unaffected. Substitution must be evaluated against the application's regulatory and compliance requirements.

Q: What are the key parameters that determine if a part can substitute for CD15FD331GO3F?

A: Substitution eligibility is determined by matching the following parameters: capacitance value (330 pF), tolerance (±2%), voltage rating (500 V minimum), dielectric material (Mica), mounting type (Through Hole), package type (Radial), lead spacing (0.232" / 5.90mm), and operating temperature range (-55°C to 125°C). Any deviation in these parameters disqualifies a component from substitution. Series designation, RoHS status, and REACH classification do not affect electrical or mechanical compatibility but must be considered within the application's compliance framework.

Q: Are the physical dimensions identical between CD15FD331GO3F and CM05FD331GO3?

A: Yes. Both components share identical physical dimensions: 0.469" L x 0.209" W (11.90mm x 5.30mm) with a maximum seated height of 0.390" (9.90mm). Lead spacing is 0.232" (5.90mm) for both parts. PCB footprint compatibility is guaranteed, and no layout modifications are required when substituting between these components.

Q: What is the difference between the CD15 and CM05 series designations?

A: The series designation indicates the product line within Cornell Dubilier Electronics' mica capacitor portfolio. The CD15 series represents the current product line with RoHS3 compliance certification. The CM05 series represents an earlier product generation that does not carry RoHS compliance certification. Both series are manufactured by the same company and share identical electrical and mechanical specifications for this particular part number configuration.

Q: Which part should be selected for applications requiring RoHS compliance documentation?

A: The CD15FD331GO3F must be selected for applications requiring RoHS compliance. This component carries explicit ROHS3 Compliant certification and REACH Unaffected status. The CM05FD331GO3 is RoHS non-compliant and therefore unsuitable for applications with regulatory compliance requirements.

Q: Is there a performance difference between these two capacitors?

A: No. Both the CD15FD331GO3F and CM05FD331GO3 are mica dielectric capacitors with identical electrical specifications: 330 pF capacitance, ±2% tolerance, 500 V voltage rating, and -55°C to 125°C operating temperature range. Electrical performance, frequency response, temperature stability, and reliability characteristics are equivalent. Differences are limited to regulatory compliance status and product line designation.
