Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FD331FO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (330 pF), tolerance (±1%), and rated voltage (500 V) must match exactly. The mica dielectric material is a defining characteristic of this component class and cannot be substituted with alternative dielectric types.

Mechanical Parameters: Mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70 mm), physical dimensions (0.642" L x 0.189" W), and maximum seated height (0.500") must remain consistent to ensure PCB compatibility and assembly feasibility.

Environmental Parameters: Operating temperature range (-55°C to 125°C) establishes the thermal performance envelope for equivalent parts.

Substitute parts within the CD19 series from Cornell Dubilier Electronics that maintain these exact specifications are classified as parametric equivalents. Variations in regulatory compliance status (RoHS, REACH) do not affect electrical or mechanical substitutability but may influence application suitability based on end-use requirements.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD331FO3F and CD19FD331FO3 are parametric equivalents with identical electrical and mechanical specifications. Both parts are active products from Cornell Dubilier Electronics in the CD19 series.

For applications requiring RoHS3 compliance: The CD19FD331FO3F is the appropriate selection, as it meets ROHS3 Compliant status and REACH Unaffected requirements.

For applications with REACH compliance requirements: The CD19FD331FO3F is the appropriate selection, as it maintains REACH Unaffected status.

For applications without specific regulatory compliance mandates: Either part may be selected based on availability and supply chain considerations. The CD19FD331FO3 offers equivalent electrical and mechanical performance with slightly higher inventory availability (909 pcs vs. 891 pcs).

Both parts share identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the CD19FD331FO3 be used as a direct replacement for the CD19FD331FO3F?

A: The CD19FD331FO3 is a parametric equivalent with identical capacitance (330 pF), tolerance (±1%), voltage rating (500 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70 mm), physical dimensions, and operating temperature range. Direct electrical and mechanical substitution is supported. Regulatory compliance differences (RoHS and REACH status) must be evaluated against application requirements.

Q: What are the critical parameters that determine substitutability for this mica capacitor?

A: Substitutability is determined by exact equivalence in: capacitance value (330 pF), tolerance (±1%), rated voltage (500 V), dielectric material (mica), mounting type (through hole), package type (radial), lead spacing (0.343" / 8.70 mm), physical dimensions (0.642" L x 0.189" W), and maximum seated height (0.500"). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Are there any physical compatibility concerns when substituting between these parts?

A: No. Both parts maintain identical lead spacing (0.343" / 8.70 mm), physical dimensions (0.642" L x 0.189" W / 16.30 mm x 4.80 mm), and maximum seated height (0.500" / 12.70 mm). PCB footprints and assembly processes remain unchanged.

Q: What is the difference between the RoHS and REACH compliance status of these parts?

A: The CD19FD331FO3F is ROHS3 Compliant and REACH Unaffected. The CD19FD331FO3 is RoHS non-compliant and REACH Affected. These designations reflect regulatory compliance certifications and do not affect electrical or mechanical performance. Selection should be based on end-use application requirements and regional regulatory mandates.

Q: Can I mix CD19FD331FO3F and CD19FD331FO3 components in the same production batch?

A: Electrical and mechanical mixing is supported due to parametric equivalence. However, regulatory compliance tracking and documentation requirements may necessitate separate inventory management and assembly line segregation depending on application certification requirements and quality assurance protocols.
