CM05FD331JO3 Equivalent & Substitute Parts

Part Overview

The CM05FD331JO3 is a 330 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE) in the CM05 series. This through-hole radial component is designed for general-purpose applications requiring high voltage stability and precision capacitance values. The part is currently active in production with 1400 units in stock.

Equivalent substitute parts are necessary when the original CM05FD331JO3 becomes unavailable, when alternative compliance certifications are required, or when design revisions necessitate component standardization across product lines. The CD15 series substitutes provide direct functional equivalence while offering different regulatory compliance profiles.

Substitute Part Grouping Explanation

Substitution of the CM05FD331JO3 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 330 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 ~ 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.232" (5.90mm) (exact match required)
• Physical Dimensions: 0.469" L x 0.209" W, Height 0.390" max (exact match required)

The CD15FD331JO3 and CD15FD331JO3F are direct parametric equivalents of the CM05FD331JO3. Both substitute parts maintain identical electrical specifications and physical form factors, enabling pin-for-pin and footprint-compatible replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

CM05FD331JO3: Select this part for applications where REACH-affected component status is acceptable and RoHS non-compliance aligns with product requirements. This part maintains the original CM05 series designation and is suitable for legacy designs or applications without RoHS/REACH restrictions.

CD15FD331JO3: This substitute provides identical electrical and mechanical performance to the CM05FD331JO3 while maintaining the same RoHS and REACH compliance profile. Use this part when CD15 series standardization is preferred within the same regulatory framework.

CD15FD331JO3F: This substitute is the optimal choice for applications requiring ROHS3 compliance and REACH-unaffected status. The "F" suffix indicates enhanced environmental compliance certification. Select this part for new designs, products destined for regulated markets, or when compliance documentation is mandatory.

All three parts are functionally interchangeable at the circuit level due to identical electrical specifications and physical form factors. Selection between them is determined by regulatory compliance requirements and supply chain standardization objectives.

Frequently Asked Questions (FAQ)

Q: Can CM05FD331JO3 be directly replaced with CD15FD331JO3 or CD15FD331JO3F?

A: Yes. Both CD15 series parts are direct substitutes. They share identical capacitance (330 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C ~ 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.232"), and physical dimensions. Pin-for-pin and footprint-compatible replacement is supported.

Q: What is the difference between CD15FD331JO3 and CD15FD331JO3F?

A: The primary difference is regulatory compliance. CD15FD331JO3 maintains RoHS non-compliant and REACH-affected status, matching the original CM05FD331JO3. CD15FD331JO3F is ROHS3 compliant and REACH-unaffected, making it suitable for applications with stricter environmental regulations.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts have identical physical dimensions (0.469" L x 0.209" W), maximum seated height (0.390"), and lead spacing (0.232"). They are mechanically interchangeable on PCBs designed for radial through-hole capacitors with 5.90mm lead spacing.

Q: Which substitute should be selected for new product designs?

A: CD15FD331JO3F is recommended for new designs due to ROHS3 compliance and REACH-unaffected status, providing alignment with current environmental regulations and reducing future compliance risks.

Q: Do all three parts operate within the same temperature range?

A: Yes. CM05FD331JO3, CD15FD331JO3, and CD15FD331JO3F all operate across -55°C ~ 125°C, ensuring thermal performance equivalence across all operating conditions.

Q: Is there a difference in moisture sensitivity between these parts?

A: CM05FD331JO3 specifies MSL 1 (Unlimited). CD15FD331JO3 and CD15FD331JO3F list MSL as Not Applicable, indicating mica capacitors do not require moisture sensitivity classification.
