CDV19FF181JO3 Equivalent & Substitute Parts

Part Overview

The CDV19FF181JO3 is a 180 pF mica capacitor rated for 1 kV, manufactured by Cornell Dubilier Electronics (CDE) in the CDV19 series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance and high voltage performance across an operating temperature range of -55°C to 125°C. The part is currently active in production with 855 units in stock.

Identification of substitute parts becomes necessary when the original part number is unavailable, when supply chain constraints limit access to specific manufacturing variants, or when design requirements permit selection from equivalent alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CDV19FF181JO3 is determined by strict equivalence across the following critical parameters:

Capacitance Value: 180 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 1 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: 0.343" / 8.70 mm (exact match required)
Physical Dimensions: 0.642" L x 0.189" W / 16.30 mm x 4.80 mm (exact match required)
Maximum Seated Height: 0.500" / 12.70 mm (exact match required)

The substitute part CDV19FF181JO3F meets all electrical and mechanical parameters specified above. Differences in regulatory compliance status (RoHS and REACH) do not affect functional equivalence but may influence selection based on end-application requirements.

Engineering Selection Recommendations

CDV19FF181JO3F is a direct functional equivalent to CDV19FF181JO3. Both parts are manufactured by Cornell Dubilier Electronics within the CDV19 series and maintain identical electrical performance and mechanical compatibility.

The primary distinction between these parts is regulatory compliance status. CDV19FF181JO3F carries ROHS3 compliance and REACH unaffected status, whereas CDV19FF181JO3 is RoHS non-compliant and REACH affected. Selection between these variants should be based on end-application regulatory requirements and supply chain availability.

Current inventory status shows CDV19FF181JO3F at 1124 units in stock compared to 855 units for CDV19FF181JO3, indicating potentially improved availability for the compliant variant.

Frequently Asked Questions (FAQ)

Q: Can CDV19FF181JO3F be used as a direct replacement for CDV19FF181JO3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance (180 pF), tolerance (±5%), voltage rating (1 kV), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70 mm), and physical dimensions. PCB layout and circuit performance remain unchanged.

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

A: The functional specifications are identical. The differences are regulatory: CDV19FF181JO3F is ROHS3 compliant and REACH unaffected, while CDV19FF181JO3 is RoHS non-compliant and REACH affected. These distinctions affect compliance documentation and regional market eligibility, not component performance.

Q: Are there any physical differences that would affect PCB assembly?

A: No. Both parts have identical lead spacing (0.343" / 8.70 mm), body dimensions (0.642" L x 0.189" W / 16.30 mm x 4.80 mm), and maximum seated height (0.500" / 12.70 mm). Assembly processes, footprints, and placement parameters are identical.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements for your end application. If ROHS3 compliance or REACH unaffected status is required, specify CDV19FF181JO3F. If no regulatory constraints apply, either part is functionally suitable. Verify supply chain availability for your production timeline.

Q: Can I mix these parts in the same production batch?

A: Yes, from a functional and mechanical standpoint. However, if regulatory documentation or traceability requirements mandate consistent compliance status across all units, maintain separate part number specifications.
