Key Parameters

Substitute Part Grouping Explanation

Substitution for the CDV30FK121FO3 is determined by the following critical electrical and mechanical parameters:

• Capacitance: 120 pF (±1% tolerance)
• Voltage Rating: 2.5 kV minimum
• Dielectric Material: Mica
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.437" (11.10mm)
• Physical Dimensions: 0.780" L x 0.252" W x 0.858" H (Max)
• Operating Temperature Range: -55°C ~ 125°C

Substitute parts within this category must match all specified electrical parameters and physical dimensions to ensure compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CDV30FK121FO3 and CDV30FK121FO3F are active products from Cornell Dubilier Electronics with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory compliance requirements:

CDV30FK121FO3F is the recommended substitute for new designs and applications requiring ROHS3 compliance and REACH unaffected status. This variant offers superior regulatory alignment for current manufacturing standards.

CDV30FK121FO3 remains suitable for applications without RoHS3 compliance mandates or where REACH affected status is acceptable. Both parts deliver equivalent electrical performance and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Are CDV30FK121FO3 and CDV30FK121FO3F electrically equivalent? A: Yes. Both parts share identical capacitance (120 pF), voltage rating (2.5 kV), tolerance (±1%), dielectric material (mica), and operating temperature range (-55°C ~ 125°C).

Q: Can these parts be used interchangeably in existing designs? A: Yes. The parts are mechanically and electrically identical, with matching lead spacing (0.437"), dimensions (0.780" L x 0.252" W), and through-hole radial mounting configuration.

Q: What is the difference between these two part numbers? A: The primary differences are compliance certifications. CDV30FK121FO3F is ROHS3 compliant and REACH unaffected, while CDV30FK121FO3 is RoHS non-compliant and REACH affected. Electrical performance is identical.

Q: Which part should be used for new designs? A: Selection depends on regulatory requirements. CDV30FK121FO3F is preferred for applications requiring RoHS3 compliance. CDV30FK121FO3 is suitable where such compliance is not mandated.

Q: Are there any restrictions on using these parts in specific applications? A: No restrictions are imposed by the provided specifications. Both are rated for -55°C ~ 125°C operation and carry EAR99 ECCN classification.
