• Physical dimensions: 0.661" L x 0.220" W (16.80mm x 5.60mm)
• Maximum seated height: 0.520" (13.20mm)

Both parts are manufactured by Cornell Dubilier Electronics within the CD19 series and carry active product status. The substitute relationship is based on complete parametric equivalence with no deviations in electrical performance or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD122FO3 and CD19FD122FO3F are parametrically equivalent components with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and compliance requirements rather than functional performance.

CD19FD122FO3 is appropriate for applications where RoHS non-compliance is acceptable and REACH-affected status does not present constraints.

CD19FD122FO3F is the required selection for applications subject to ROHS3 compliance mandates or REACH-unaffected material sourcing requirements. This variant maintains full electrical and mechanical compatibility while addressing regulatory compliance obligations.

Both parts are active products from Cornell Dubilier Electronics with confirmed inventory availability. The choice between them depends solely on the regulatory framework governing the end application.

Frequently Asked Questions (FAQ)

Q: Are CD19FD122FO3 and CD19FD122FO3F electrically interchangeable?

A: Yes. Both parts have identical capacitance (1200 pF), tolerance (±1%), rated voltage (500 V), temperature range (-55°C ~ 125°C), and dielectric material (Mica). Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both components share identical mechanical specifications: radial through-hole mounting, 0.343" (8.70mm) lead spacing, 0.661" L x 0.220" W (16.80mm x 5.60mm) dimensions, and 0.520" (13.20mm) maximum seated height. PCB layout and footprint compatibility is identical.

Q: What is the difference between CD19FD122FO3 and CD19FD122FO3F?
