Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDV19FF331JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Lead Spacing: 0.343" (8.70 mm) (exact match required)
• Physical Dimensions: 0.650" L x 0.201" W, Height 0.512" max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The identified substitute part CDV19FF331JO3F maintains all electrical and mechanical parameters identical to the main part. Differences exist only in compliance certifications and regulatory status, which may be relevant for specific application requirements or supply chain constraints.

Parameter Comparison

Engineering Selection Recommendations

CDV19FF331JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected materials are permitted. Current inventory: 1129 pcs.

CDV19FF331JO3F is the appropriate selection for applications requiring RoHS3 compliance and REACH unaffected status. This variant meets modern regulatory requirements for consumer electronics, industrial equipment, and export-controlled applications. Current inventory: 1211 pcs.

Both parts are manufactured by Cornell Dubilier Electronics in the active CDV19 series and are electrically and mechanically identical. Selection between them depends solely on compliance requirements for the target application or end market.

Frequently Asked Questions (FAQ)

Q: Can CDV19FF331JO3F be used as a direct replacement for CDV19FF331JO3?

A: Yes. All electrical parameters (capacitance, tolerance, voltage rating, temperature range) and mechanical parameters (dimensions, lead spacing, mounting type) are identical. The only differences are RoHS and REACH compliance status. Substitution is valid from an electrical and mechanical standpoint.

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

A: The CDV19FF331JO3F variant includes RoHS3 compliance and REACH unaffected status, while the CDV19FF331JO3 is RoHS non-compliant and REACH affected. Both are 330 pF, 1 kV, ±5% tolerance mica capacitors in radial through-hole packages.

Q: Which part should I specify for new designs?

A: Selection depends on your application's regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance, specify CDV19FF331JO3F. For applications without these constraints, either part is acceptable based on availability.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: 0.650" L x 0.201" W (16.50 mm x 5.10 mm), height 0.512" max, and lead spacing of 0.343" (8.70 mm). They are pin-compatible and footprint-compatible.

Q: Can I mix these parts in the same assembly?

A: Yes. Since all electrical and mechanical parameters are identical, both parts can be used interchangeably in the same circuit board assembly without affecting circuit performance or PCB layout.
