CDV19EF330JO3 Equivalent & Substitute Parts

Part Overview

The CDV19EF330JO3 is a 33 pF mica capacitor rated for 1 kV operation in a radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active and suitable for general-purpose applications requiring stable capacitance and high voltage performance across the operating temperature range of -55°C to 125°C.

Identification of substitute parts becomes necessary when the original part number is unavailable from inventory or when design requirements mandate compliance with specific regulatory standards such as RoHS3 certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDV19EF330JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 33 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.343" / 8.70 mm (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)

The substitute part CDV19EF330JO3F maintains identical electrical and mechanical specifications to the main part number, with the primary distinction being regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

CDV19EF330JO3F is the direct substitute for CDV19EF330JO3 when regulatory compliance is a design requirement. The CDV19EF330JO3F variant achieves ROHS3 compliance and REACH unaffected status while maintaining identical electrical performance and physical form factor.

Selection between these part numbers depends on the following criteria:

• Use CDV19EF330JO3 when RoHS compliance is not mandated and REACH-affected materials are acceptable for the application.
• Use CDV19EF330JO3F when designs require ROHS3 compliance or when REACH unaffected status is specified in procurement requirements.

Both parts are active products with confirmed inventory availability and are suitable for direct substitution in circuit designs without modification to PCB layout or schematic connections.

Frequently Asked Questions (FAQ)

Q: Can CDV19EF330JO3F be used as a direct replacement for CDV19EF330JO3?

A: Yes. The CDV19EF330JO3F is a direct substitute with identical electrical specifications (33 pF, ±5%, 1 kV), dielectric material (mica), and physical dimensions. The primary difference is regulatory compliance status.

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

A: The CDV19EF330JO3F achieves ROHS3 compliance and REACH unaffected status, while the CDV19EF330JO3 is RoHS non-compliant and REACH affected. All other specifications are identical.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts share identical dimensions (0.642" L x 0.189" W), height (0.500" max), and lead spacing (0.343" / 8.70 mm). No PCB layout modifications are required when substituting between these part numbers.

Q: Which part should I specify for new designs?

A: Specify CDV19EF330JO3F for new designs to ensure compliance with current RoHS3 and REACH regulations. The CDV19EF330JO3 is suitable only for legacy applications where regulatory compliance is not required.

Q: Are both parts currently in production?

A: Yes. Both CDV19EF330JO3 and CDV19EF330JO3F are active products with confirmed inventory availability.

Q: Can I substitute with other capacitor values or voltage ratings?

A: No. Substitution is limited to parts with identical capacitance (33 pF), tolerance (±5%), voltage rating (1 kV), and dielectric material (mica). Different values or ratings require circuit re-evaluation and are not considered equivalent substitutes.
