CM06FD122GO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CM06FD122GO3 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 with general-purpose application capability. The CM06 series represents an established design suitable for high-reliability circuits requiring stable capacitance and low dielectric loss characteristics inherent to mica dielectric construction.

Identification of equivalent and substitute parts becomes necessary when the CM06FD122GO3 reaches end-of-life status, inventory depletion occurs, or when design requirements permit selection from alternative series within the same electrical and mechanical parameter space. The CD19FD122GO3F provides a direct parametric equivalent meeting identical electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CM06FD122GO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD19FD122GO3F qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Matching:

• Capacitance value: 1200 pF (identical)
• Tolerance specification: ±2% (identical)
• Voltage rating: 500 V (identical)
• Dielectric material: Mica (identical)
• Operating temperature range: -55°C to 125°C (identical)

Mechanical Parameter Matching:

• Mounting technology: Through Hole (identical)
• Package configuration: Radial (identical)
• Lead spacing: 0.343 inches / 8.70 mm (identical)
• Physical envelope: 0.661" L × 0.220" W (identical)
• Maximum seated height: 0.520 inches / 13.20 mm (identical)

Functional Classification: Both components are classified as general-purpose mica capacitors with identical feature sets. The CD19 series represents an alternative product line from the same manufacturer that maintains full compatibility with CM06 series specifications within the stated parameter boundaries.

Engineering Selection Recommendations

Primary Selection: CM06FD122GO3

The CM06FD122GO3 remains the preferred component when inventory availability and existing design validation support its continued use. This part maintains Active product status with 899 units currently in stock. Selection of this part number preserves design continuity and eliminates qualification requirements.

Alternative Selection: CD19FD122GO3F

The CD19FD122GO3F qualifies as a direct parametric substitute when CM06FD122GO3 availability becomes constrained or when design requirements permit component substitution. This part demonstrates superior regulatory compliance posture:

• ROHS3 Compliant status (versus RoHS non-compliant for CM06FD122GO3)
• REACH Unaffected classification (versus REACH Affected for CM06FD122GO3)

Both components share identical electrical performance characteristics, mechanical dimensions, and thermal operating ranges. The CD19FD122GO3F currently maintains higher inventory availability at 1,021 units in stock.

Substitution Criteria Met: All critical parameters—capacitance, tolerance, voltage rating, dielectric material, temperature range, mounting type, package configuration, and lead spacing—are identical between both parts. Physical dimensions and maximum seated height specifications match exactly, ensuring PCB compatibility without layout modification.

Regulatory Consideration: Applications subject to RoHS3 or REACH compliance requirements should specify CD19FD122GO3F. Applications without such regulatory constraints may select either part based on availability and inventory management priorities.

Frequently Asked Questions (FAQ)

Q: Can CD19FD122GO3F be used as a direct replacement for CM06FD122GO3 without PCB modification?

A: Yes. Both components share identical lead spacing (0.343 inches / 8.70 mm), physical dimensions (0.661" L × 0.220" W), and maximum seated height (0.520 inches). No PCB layout changes are required for mechanical compatibility.

Q: Are the electrical characteristics identical between CM06FD122GO3 and CD19FD122GO3F?

A: Yes. Both components provide 1200 pF capacitance with ±2% tolerance, 500 V voltage rating, and -55°C to 125°C operating temperature range. Dielectric material, mounting type, and package configuration are identical.

Q: What is the primary difference between these two part numbers?

A: The primary differences are regulatory compliance status and inventory availability. CD19FD122GO3F is ROHS3 Compliant and REACH Unaffected, while CM06FD122GO3 is RoHS non-compliant and REACH Affected. CD19FD122GO3F has higher current inventory (1,021 units versus 899 units).

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 or REACH compliance, specify CD19FD122GO3F. For applications without such constraints, either part is acceptable based on availability and supply chain considerations.

Q: Are there any performance differences in high-frequency or high-temperature applications?

A: No performance differences exist within the specified operating parameters. Both components operate identically across the -55°C to 125°C temperature range and maintain the same capacitance tolerance and voltage rating specifications.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both components are electrically and mechanically equivalent. Mixed usage is permissible provided that design documentation and bill of materials are updated to reflect the specific part number used in each assembly instance.

Q: What is the lead spacing measurement used for PCB hole pattern verification?

A: The lead spacing for both CM06FD122GO3 and CD19FD122GO3F is 0.343 inches, equivalent to 8.70 millimeters. This measurement defines the center-to-center distance between the two radial leads and determines PCB hole pattern compatibility.
