CD19FD122JO3F Equivalent & Substitute Parts

Part Overview

The CD19FD122JO3F is a 1200 pF mica capacitor rated for 500 V 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. Mica dielectric capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Substitute parts are identified to address inventory availability, compliance requirements, or specific application constraints while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD122JO3F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1200 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (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: 0.661" L × 0.220" W / 16.80 mm × 5.60 mm (exact match required)

The substitute part CD19FD122JO3 meets all electrical and mechanical parameters required for direct substitution. Differences in compliance certifications (RoHS status and REACH classification) do not affect functional equivalence but may influence selection based on application regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

CD19FD122JO3F is the primary selection for applications requiring ROHS3 compliance and REACH unaffected status. This part is suitable for regulated industries and applications subject to environmental directives in the European Union and equivalent jurisdictions.

CD19FD122JO3 is functionally equivalent and suitable for applications where RoHS3 compliance and REACH unaffected status are not mandatory requirements. This part provides identical electrical performance and mechanical compatibility. Selection of this substitute should be based on application regulatory environment and compliance obligations.

Both parts are active products with confirmed inventory availability. The choice between CD19FD122JO3F and CD19FD122JO3 depends solely on compliance certification requirements specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Can CD19FD122JO3 be used as a direct replacement for CD19FD122JO3F?

A: Yes. CD19FD122JO3 is electrically and mechanically equivalent to CD19FD122JO3F. Both parts share identical capacitance, voltage rating, tolerance, dielectric material, temperature range, mounting type, package configuration, and physical dimensions. Selection between the two parts depends on compliance requirements rather than functional performance.

Q: What is the difference between CD19FD122JO3F and CD19FD122JO3?

A: The parts differ in compliance certifications. CD19FD122JO3F is ROHS3 compliant and REACH unaffected. CD19FD122JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical lead spacing (0.343" / 8.70 mm), body dimensions (0.661" L × 0.220" W / 16.80 mm × 5.60 mm), and maximum seated height (0.520" / 13.20 mm). They are mechanically interchangeable in through-hole PCB applications.

Q: Which part should I select for European market applications?

A: For applications subject to European Union environmental directives, select CD19FD122JO3F, which is ROHS3 compliant and REACH unaffected. CD19FD122JO3 may not meet these regulatory requirements.

Q: Do these parts have the same operating temperature range?

A: Yes. Both CD19FD122JO3F and CD19FD122JO3 operate across the identical temperature range of -55°C to 125°C.

Q: Is the capacitance tolerance the same for both parts?

A: Yes. Both parts have ±5% capacitance tolerance at 1200 pF nominal value.
