CM06FD122JO3 Equivalent & Substitute Parts

Part Overview

The CM06FD122JO3 is a 1200 pF mica capacitor rated for 500 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed 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. Equivalent and substitute parts are identified to address inventory availability, compliance requirements, or series transitions while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the CM06FD122JO3 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, Height 0.520" max (exact match required)

The CM06FD122JO3 (CM06 series) is substitutable with CD19FD122JO3 and CD19FD122JO3F (CD19 series). Both substitute parts maintain identical electrical performance and mechanical compatibility. Differences exist only in series designation, RoHS compliance status, and REACH classification, which are secondary to functional equivalence.

Engineering Selection Recommendations

CM06FD122JO3 (Primary Part)

Select this part when the original specification calls for CM06 series designation and RoHS non-compliant status is acceptable for the application. Current inventory of 1425 units supports immediate availability for production requirements.

CD19FD122JO3 (First Substitute)

This part provides direct electrical and mechanical equivalence to CM06FD122JO3 while transitioning to the CD19 series platform. Maintains RoHS non-compliant status and REACH Affected classification. Inventory of 856 units is available. Use this substitute when CM06 series parts are unavailable and RoHS compliance is not a design requirement.

CD19FD122JO3F (Second Substitute - Compliance-Enhanced)

This part is the preferred substitute when RoHS3 compliance and REACH Unaffected status are required by design specifications or regulatory requirements. Electrical and mechanical parameters are identical to CM06FD122JO3 and CD19FD122JO3. Inventory of 835 units supports production needs. The "F" suffix indicates compliance-enhanced manufacturing. Select this variant for applications subject to RoHS3 or REACH restrictions.

All three parts are Active status products from Cornell Dubilier Electronics and are suitable for direct substitution based on compliance and availability requirements.

Frequently Asked Questions (FAQ)

Q: Can CM06FD122JO3 be replaced with CD19FD122JO3 or CD19FD122JO3F without circuit redesign?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical capacitance (1200 pF), tolerance (±5%), voltage rating (500 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), mounting type (Through Hole), package configuration (Radial), lead spacing (0.343"), and physical dimensions. Direct substitution on the PCB is possible without circuit modification.

Q: What is the difference between CD19FD122JO3 and CD19FD122JO3F?

A: The primary differences are compliance certifications. CD19FD122JO3 is RoHS non-compliant and REACH Affected. CD19FD122JO3F is ROHS3 Compliant and REACH Unaffected. Electrical and mechanical specifications are identical. Select CD19FD122JO3F when regulatory compliance with RoHS3 or REACH restrictions is required.

Q: Will the radial lead spacing of 0.343" (8.70 mm) fit existing PCB footprints designed for CM06FD122JO3?

A: Yes. All substitute parts maintain the same lead spacing of 0.343" (8.70 mm) and radial package configuration. PCB footprints designed for CM06FD122JO3 will accommodate CD19FD122JO3 and CD19FD122JO3F without modification.

Q: Are there any temperature or voltage derating considerations when substituting these parts?

A: No. All three parts operate across the identical temperature range of -55°C to 125°C and are rated for 500 V. No derating adjustments are required when substituting between CM06FD122JO3, CD19FD122JO3, and CD19FD122JO3F.

Q: Which substitute should be selected for new designs?

A: For new designs, CD19FD122JO3F is the recommended choice. It provides ROHS3 compliance and REACH Unaffected status, ensuring compatibility with current and future regulatory requirements while maintaining full electrical and mechanical equivalence.

Q: Can these parts be used interchangeably in high-frequency applications?

A: All three parts are mica dielectric capacitors with identical material composition and physical dimensions. Frequency performance characteristics are equivalent across all three part numbers.
