CD5CC040DO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD5CC040DO3 is a 4 pF mica capacitor rated for 300 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance values across wide temperature ranges.

Mica capacitors in this specification are used in RF circuits, precision timing networks, and high-reliability applications where temperature stability and low dielectric loss are critical. Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable or when alternative compliance certifications are required for specific manufacturing or regulatory environments.

Substitute Part Grouping Explanation

Substitute parts for the CD5CC040DO3 are identified based on strict parametric equivalence within the CD5 mica capacitor series. The substitution logic is based on the following mandatory matching criteria:

Critical Matching Parameters:

• Capacitance value: 4 pF (exact match required)
• Tolerance: ±0.5 pF (exact match required)
• Voltage rating: 300 V (minimum acceptable)
• Dielectric material: Mica (material class requirement)
• Operating temperature range: -55°C to 125°C (minimum acceptable)
• Mounting type: Through Hole (assembly process compatibility)
• Package configuration: Radial (footprint compatibility)
• Lead spacing: 0.118" / 3.00 mm (PCB hole pattern compatibility)

Secondary Matching Parameters:

• Physical dimensions and height (board space and clearance)
• Moisture sensitivity level (storage and handling conditions)
• Series designation: CD5 (product family consistency)

Substitute parts must satisfy all critical parameters identically. Variations in compliance certifications (RoHS status, REACH classification) do not disqualify a part from substitution eligibility when electrical and mechanical parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CD5CC040DO3F is a direct parametric equivalent to the CD5CC040DO3. All electrical and mechanical specifications are identical, including capacitance, tolerance, voltage rating, temperature range, mounting configuration, and physical dimensions.

The primary distinction between these parts is regulatory compliance status:

CD5CC040DO3: RoHS non-compliant, REACH Affected. This designation indicates the part may contain restricted substances under RoHS Directive 2011/65/EU and is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.

CD5CC040DO3F: ROHS3 Compliant, REACH Unaffected. This designation indicates the part meets RoHS Directive 2011/65/EU requirements and is not subject to REACH chemical restrictions.

Selection between these equivalent parts depends on the regulatory requirements of the end application and manufacturing jurisdiction. For applications requiring RoHS3 compliance or REACH exemption, the CD5CC040DO3F is the appropriate selection. For applications without such regulatory constraints, either part is functionally equivalent.

Both parts are Active status products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CD5CC040DO3F be used as a direct replacement for CD5CC040DO3 in existing designs?

A: Yes. The CD5CC040DO3F is a direct parametric equivalent. All electrical characteristics (capacitance, tolerance, voltage rating, temperature range) and mechanical specifications (mounting type, package configuration, lead spacing, physical dimensions) are identical. No circuit redesign or PCB modification is required.

Q: What is the difference between the two part numbers?

A: The parts are electrically and mechanically identical. The difference is regulatory compliance certification. CD5CC040DO3F is ROHS3 Compliant and REACH Unaffected, while CD5CC040DO3 is RoHS non-compliant and REACH Affected. The "F" suffix in CD5CC040DO3F indicates the RoHS3-compliant variant.

Q: Are there any performance differences between CD5CC040DO3 and CD5CC040DO3F?

A: No. Both parts are manufactured from identical materials and specifications. Performance characteristics, including capacitance stability, temperature coefficient, dielectric loss, and voltage rating, are equivalent.

Q: Which part should be selected for new designs?

A: For new designs, CD5CC040DO3F is recommended when the application is subject to RoHS3 or REACH regulations. For applications without such regulatory requirements, either part is acceptable. Verify regulatory requirements for your specific end-use application and manufacturing location.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: 0.272" L x 0.110" W (6.90 x 2.80 mm), lead spacing of 0.118" (3.00 mm), and maximum seated height of 0.189" (4.80 mm). PCB footprints and mounting hole patterns are interchangeable.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates the parts do not require special moisture control during storage or handling and can be stored under standard conditions without desiccant packaging.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C. This temperature range is suitable for industrial and military-grade applications. Verify that the specific application environment does not exceed these limits.

Q: What is the voltage derating requirement?

A: Both parts are rated for 300 V. Ensure that the applied voltage in the circuit does not exceed this rating. For safety-critical applications, apply appropriate derating factors based on circuit design standards and application requirements.
