Substitute Part Grouping Explanation

Substitution of the CD19FD122JO3 is based on strict equivalence across all electrical and mechanical parameters. The substitute part CD19FD122JO3F maintains identical specifications for:

• Capacitance value: 1200 pF
• Tolerance: ±5%
• Voltage rating: 500 V
• Dielectric material: Mica
• Operating temperature range: -55°C to 125°C
• Mounting configuration: Through hole radial
• Physical dimensions and lead spacing: 0.343" (8.70 mm)

The primary distinction between the main part and its substitute is the compliance status. The CD19FD122JO3F variant incorporates RoHS3 compliance and REACH unaffected status, whereas the CD19FD122JO3 is RoHS non-compliant and REACH affected. Both parts are classified under ECCN EAR99 and HTSUS 8532.29.0020.

Parameter Comparison

Engineering Selection Recommendations

Selection between CD19FD122JO3 and CD19FD122JO3F is determined by regulatory and compliance requirements applicable to the end application.

CD19FD122JO3 is suitable for applications where RoHS and REACH compliance are not mandated or where legacy component specifications are required. This variant maintains full electrical and mechanical compatibility with existing designs.

CD19FD122JO3F is the appropriate selection for applications subject to RoHS3 regulations or REACH compliance requirements. This variant provides identical electrical performance and physical form factor while meeting current environmental and regulatory standards.

Both parts are active products with adequate inventory availability. Selection should be based on the regulatory framework governing the end application and any existing design constraints.

Frequently Asked Questions (FAQ)

Q: Are CD19FD122JO3 and CD19FD122JO3F electrically identical?

A: Yes. Both parts have identical capacitance (1200 pF), tolerance (±5%), voltage rating (500 V), temperature range (-55°C to 125°C), and dielectric material (mica). They are direct electrical equivalents.

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

A: Yes. The parts are mechanically and electrically identical. Lead spacing, physical dimensions, and mounting configuration are the same. No PCB redesign is required.

Q: What is the difference between these two parts?

A: The primary difference is compliance status. CD19FD122JO3F is RoHS3 compliant and REACH unaffected, while CD19FD122JO3 is RoHS non-compliant and REACH affected. All other specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. For applications subject to RoHS3 or REACH regulations, use CD19FD122JO3F. For applications without these requirements, either part is acceptable based on availability and cost considerations.

Q: Are there any performance differences between these parts?

A: No. Both parts operate identically across the specified temperature range and voltage rating. Capacitance tolerance, stability, and reliability characteristics are equivalent.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing is 0.343 inches (8.70 mm) for both parts. This dimension is critical for PCB footprint compatibility.
