CM06FD392JO3 Equivalent & Substitute Parts

Part Overview

The CM06FD392JO3 is a 3900 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is designed for general-purpose applications requiring high voltage and stable dielectric performance across extended temperature ranges. The part is currently active in production with 673 units in stock.

Substitute parts are necessary when the original CM06 series becomes unavailable, when RoHS compliance is required for new designs, or when alternative packaging configurations are needed while maintaining identical electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM06FD392JO3 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 3900 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)

Mechanical Equivalence Criteria:

• 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: 0.689" L × 0.311" W (17.50 mm × 7.90 mm) (exact match required)
• Height seated maximum: 0.559" (14.20 mm) (exact match required)

Both substitute parts (CD19FD392JO3 and CD19FD392JO3F) meet all electrical and mechanical equivalence criteria. The CD19 series represents an alternative product line from the same manufacturer with identical performance specifications and board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

CM06FD392JO3 (Original Part): Use this part for existing designs and applications where RoHS compliance is not a requirement. The part is active in production with adequate inventory availability.

CD19FD392JO3 (Substitute - RoHS Non-Compliant): This substitute provides identical electrical and mechanical performance to the CM06FD392JO3. It is suitable for applications where RoHS compliance is not mandated. Inventory availability is higher than the original part (1139 units). This part is REACH Affected.

CD19FD392JO3F (Substitute - RoHS3 Compliant): This substitute provides identical electrical and mechanical performance while meeting RoHS3 compliance requirements. It is suitable for new designs, applications requiring environmental compliance, and regions with strict regulatory requirements. This part is REACH Unaffected. Inventory availability is significantly higher (9520 units), providing superior supply chain reliability.

Selection between substitutes should be based on regulatory compliance requirements for the target application and end-use market. All three parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the CM06FD392JO3 and CD19FD392JO3 electrically identical?

A: Yes. Both parts have identical capacitance (3900 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), and operating temperature range (-55°C to 125°C). They are electrical equivalents.

Q: Can I use CD19FD392JO3F as a direct replacement for CM06FD392JO3 on existing circuit boards?

A: Yes. The CD19FD392JO3F is mechanically and electrically identical to the CM06FD392JO3. Lead spacing (0.343" / 8.70 mm), physical dimensions (0.689" L × 0.311" W), and height (0.559" max) are identical, enabling direct board-level substitution.

Q: What is the difference between CD19FD392JO3 and CD19FD392JO3F?

A: Both parts are electrically and mechanically identical. The primary differences are: CD19FD392JO3F is RoHS3 compliant while CD19FD392JO3 is not; CD19FD392JO3F is REACH Unaffected while CD19FD392JO3 is REACH Affected; CD19FD392JO3F has significantly higher inventory availability (9520 units versus 1139 units).

Q: Which substitute should I select for a new design?

A: For new designs, CD19FD392JO3F is the recommended selection. It provides RoHS3 compliance, REACH compliance, and superior inventory availability while maintaining complete electrical and mechanical equivalence.

Q: Are all three parts suitable for high-voltage applications?

A: Yes. All three parts are rated for 500 V operation and are suitable for high-voltage applications within this voltage specification.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing is 0.343 inches (8.70 mm) for all three parts, enabling direct substitution on existing through-hole PCB layouts.

Q: Do these mica capacitors require any special handling?

A: All three parts have Moisture Sensitivity Level 1 (MSL 1 for CM06FD392JO3) or Not Applicable (for CD19 series), indicating minimal moisture sensitivity and standard handling procedures.
