Substitute Part Grouping Explanation

Substitution eligibility for the CDV19EF390JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 39 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.343" (8.70 mm) (exact match required)
• Physical Envelope: 0.642" L x 0.189" W, 0.500" H max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The substitute part CDV19EF390JO3F meets all electrical and mechanical requirements for direct substitution. The primary distinction between the main part and its substitute relates to regulatory compliance certifications rather than functional performance.

Parameter Comparison

Engineering Selection Recommendations

CDV19EF390JO3F is the direct substitute for CDV19EF390JO3. Both parts are manufactured by Cornell Dubilier Electronics within the CDV19 series and maintain identical electrical performance and physical specifications.

The CDV19EF390JO3F offers improved regulatory compliance status:

• RoHS3 Compliance: The substitute meets ROHS3 requirements, whereas the original part is RoHS non-compliant.
• REACH Status: The substitute is REACH Unaffected, compared to the original part which is REACH Affected.

Both parts share the same ECCN classification (EAR99) and HTSUS code (8532.29.0020), indicating equivalent export and tariff treatment.

Selection between these parts should be based on regulatory requirements applicable to the end application and target market. Where RoHS3 and REACH compliance are mandatory, CDV19EF390JO3F is the appropriate choice. Both parts deliver identical functional performance in circuit applications.
