CDV30FK182FO3F Equivalent & Substitute Parts

Part Overview

The CDV30FK182FO3F is a 1800 pF mica capacitor rated for 2.5 kV operation, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is designed for general-purpose applications requiring high voltage performance and stable capacitance characteristics across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance certification. Substitute parts are identified when inventory constraints, supply chain disruptions, or design revision requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CDV30FK182FO3F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1800 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 2.5 kV (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.437" / 11.10 mm (exact match required)
• Physical Dimensions: 0.811" L x 0.370" W / 20.60 mm x 9.40 mm (exact match required)
• Maximum Seated Height: 0.902" / 22.90 mm (exact match required)

The CDV30FK182FO3 qualifies as a parametric equivalent based on identical electrical specifications and mechanical form factor. Differences in regulatory compliance status do not affect functional interchangeability in applications where the substitute part's compliance profile is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CDV30FK182FO3F is the preferred choice for applications requiring ROHS3 compliance and REACH unaffected status. This part meets modern regulatory requirements for commercial and industrial electronics manufacturing.

Substitute Selection: CDV30FK182FO3 is electrically and mechanically identical to the primary part and is suitable for applications where RoHS3 compliance is not a requirement. The REACH Affected status indicates this part may contain substances of concern and requires compliance verification within the end-use application's regulatory framework.

Both parts are active products with confirmed inventory availability. Selection between these two parts should be based on the specific regulatory and compliance requirements of the end application and the manufacturing region.

Frequently Asked Questions (FAQ)

Q: Can CDV30FK182FO3 be used as a direct replacement for CDV30FK182FO3F?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (1800 pF), tolerance (±1%), voltage rating (2.5 kV), dielectric material (mica), operating temperature range (-55°C to 125°C), and physical dimensions. The difference lies in regulatory compliance status. CDV30FK182FO3 is RoHS non-compliant and REACH Affected, while CDV30FK182FO3F is ROHS3 Compliant and REACH Unaffected. Substitution is permissible only if the application's compliance requirements allow for the substitute part's regulatory profile.

Q: What are the critical parameters that must match for substitution?

A: All of the following parameters must be identical: capacitance value (1800 pF), tolerance (±1%), voltage rating (2.5 kV), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.437" / 11.10 mm), and physical dimensions (0.811" L x 0.370" W / 20.60 mm x 9.40 mm). Any deviation in these parameters disqualifies a part from substitution.

Q: Are there any physical compatibility issues between these parts?

A: No. Both the CDV30FK182FO3F and CDV30FK182FO3 share identical lead spacing (0.437" / 11.10 mm), body dimensions (0.811" L x 0.370" W), and maximum seated height (0.902" / 22.90 mm). They are pin-compatible and occupy the same footprint on printed circuit boards.

Q: What is the difference between ROHS3 Compliant and RoHS non-compliant status?

A: ROHS3 Compliant indicates the part meets the Restriction of Hazardous Substances Directive 3 requirements, restricting the use of specific hazardous materials. RoHS non-compliant parts may contain restricted substances and are subject to regulatory limitations in certain markets and applications. Selection depends on the end-use application's geographic and industry-specific compliance requirements.

Q: Does REACH Affected status impact electrical performance?

A: No. REACH Affected status indicates the part may contain substances of concern under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. This is a regulatory and supply chain consideration, not an electrical or performance characteristic. Electrical performance remains identical between both parts.
