Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM06FD122FO3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 1200 pF
• Tolerance: ±1%
• Voltage rating: 500 V
• Dielectric material: Mica
• Operating temperature range: -55°C ~ 125°C
• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.343" (8.70mm)

The substitute part CD19FD122FO3F meets all mandatory electrical and mechanical parameters, confirming direct functional equivalence. Both components share identical capacitance, voltage rating, tolerance, temperature performance, and physical dimensions. The primary distinction lies in product series designation (CM06 versus CD19) and compliance certifications.

Engineering Selection Recommendations

CM06FD122FO3 Selection Criteria: The CM06FD122FO3 remains suitable for applications where RoHS non-compliance is acceptable and REACH-affected material usage is permitted. This component is appropriate for legacy system maintenance, non-regulated markets, or applications with established compliance exemptions.

CD19FD122FO3F Selection Criteria: The CD19FD122FO3F is the preferred substitute when ROHS3 compliance and REACH unaffected status are required. This component is mandated for new designs targeting regulated markets, consumer electronics, and applications subject to environmental compliance directives. The CD19FD122FO3F provides superior compliance posture while maintaining complete electrical and mechanical equivalence.

Both components are Active status products with established manufacturing support and inventory availability. Selection between these parts should be driven by regulatory requirements and compliance obligations specific to the end application and target market.
