CD15CD040DO3 Mica Capacitor

Part Overview

The CD15CD040DO3 is a 4 pF mica capacitor rated for 500 V operation in a radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is part of the active CD15 series and is suitable for general-purpose applications requiring stable capacitance over a wide temperature range (-55°C to 125°C). Alternative models may be necessary to meet specific regulatory compliance requirements, particularly RoHS3 compliance and REACH status considerations.

Key Parameters

Substitute Part Grouping Explanation

The substitute part CD15CD040DO3F is classified as a parametric equivalent because it maintains identical electrical characteristics and mechanical specifications with the main part. Substitution eligibility is determined strictly by the following key parameters:

• Capacitance: 4 pF (identical)
• Tolerance: ±0.5 pF (identical)
• Voltage Rating: 500 V (identical)
• Dielectric Material: Mica (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Lead Spacing: 0.232" (5.90 mm) (identical)
• Physical Dimensions: 0.449" L × 0.169" W (11.40 mm × 4.30 mm) (identical)
• Height - Seated (Max): 0.358" (9.10 mm) (identical)

The CD15CD040DO3F variant differs in regulatory compliance status, making it suitable for applications with RoHS3 compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

CD15CD040DO3: Select this part for applications without RoHS3 compliance requirements. The part carries Active product status and is available in sufficient inventory (753 units). REACH Affected status indicates potential restrictions in certain regulatory jurisdictions.

CD15CD040DO3F: This variant is the preferred selection for applications requiring RoHS3 compliance and REACH Unaffected status. Both parts are electrically and mechanically identical, ensuring direct interchangeability in circuit designs. Higher inventory availability (940 units) supports consistent supply chain performance.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. The CD15CD040DO3 and CD15CD040DO3F are parametric equivalents with identical capacitance (4 pF), tolerance (±0.5 pF), voltage rating (500 V), temperature range (-55°C to 125°C), and all other electrical characteristics.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. Both parts share identical mechanical specifications, including radial package, lead spacing (0.232" / 5.90 mm), physical dimensions (0.449" L × 0.169" W), and seated height (0.358" max). They require identical PCB footprints and mounting methods.

Q: What is the difference between these two part numbers? A: The primary difference is regulatory compliance. The CD15CD040DO3F meets RoHS3 compliance requirements and carries REACH Unaffected status, while the CD15CD040DO3 does not meet these certifications. All electrical and mechanical parameters remain identical.

Q: Which part should I specify for new designs? A: Specify CD15CD040DO3F for new designs unless specific legacy or non-compliance requirements mandate the CD15CD040DO3. The RoHS3-compliant variant supports broader market acceptance and future regulatory alignment.

Q: Are there inventory considerations? A: The CD15CD040DO3F has higher current inventory (940 units) compared to the CD15CD040DO3 (753 units). Both parts maintain Active product status.
