CD10ED330JO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD10ED330JO3 is a 33 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 a general-purpose capacitor suitable for applications requiring stable capacitance and high voltage performance across an extended temperature range of -55°C to 125°C. The part maintains Active product status and is available in bulk packaging with 1142 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same dielectric material, voltage rating, capacitance value, and physical form factor. Identifying qualified substitutes ensures design flexibility and supply chain continuity while preserving circuit performance and reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD10ED330JO3 mica capacitor is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 33 pF (exact match required)
• Voltage Rating: 500 V (minimum acceptable rating)
• Dielectric Type: Mica (material specification)
• Tolerance: ±5% (electrical accuracy class)
• Mounting Configuration: Through Hole Radial (physical form factor)
• Lead Spacing: 0.142" (3.60mm) (PCB compatibility)
• Physical Dimensions: 0.370" L x 0.189" W x 0.339" H maximum (board layout fit)
• Operating Temperature Range: -55°C ~ 125°C (thermal performance envelope)

Substitute parts must satisfy all parameters listed above to ensure direct replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the CD10ED330JO3 and CM04ED330JO3 are Active product status components manufactured by Cornell Dubilier Electronics and maintain identical electrical and mechanical specifications across all critical substitution parameters. Both parts are subject to REACH compliance requirements and carry the same ECCN (EAR99) and HTSUS (8532.29.0020) classifications.

The CM04ED330JO3 represents a parametric equivalent substitute for the CD10ED330JO3. Selection between these two parts may be based on:

• Inventory Availability: CD10ED330JO3 has 1142 units in stock; CM04ED330JO3 has 788 units in stock
• Series Designation: CD10 series versus CM04 series (different product lines within CDE portfolio)
• Moisture Sensitivity Classification: CD10ED330JO3 lists MSL as Not Applicable; CM04ED330JO3 specifies MSL 1 (Unlimited)

Both parts satisfy identical functional and physical requirements for direct substitution in through-hole radial mica capacitor applications rated at 500 V with 33 pF capacitance.

Frequently Asked Questions (FAQ)

Q: Can the CM04ED330JO3 be used as a direct replacement for the CD10ED330JO3?

A: Yes. The CM04ED330JO3 meets all electrical and mechanical parameters required for direct substitution. Both parts share identical capacitance (33 pF), voltage rating (500 V), tolerance (±5%), dielectric material (mica), mounting type (through hole radial), lead spacing (0.142" / 3.60mm), physical dimensions (0.370" L x 0.189" W x 0.339" H maximum), and operating temperature range (-55°C ~ 125°C).

Q: What is the difference between the CD10 and CM04 series?

A: CD10 and CM04 are different product series within the Cornell Dubilier Electronics mica capacitor portfolio. Both series maintain equivalent electrical and mechanical specifications for the 33 pF, 500 V radial configuration. Series designation reflects internal product line organization and does not affect functional compatibility.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry identical REACH compliance status (REACH Affected) and ECCN classification (EAR99). Both are RoHS non-compliant. The primary difference is the Moisture Sensitivity Level (MSL) designation: CD10ED330JO3 lists MSL as Not Applicable, while CM04ED330JO3 specifies MSL 1 (Unlimited). This difference does not affect substitution eligibility for standard through-hole applications.

Q: Will the physical dimensions allow these parts to fit in the same PCB footprint?

A: Yes. Both the CD10ED330JO3 and CM04ED330JO3 share identical physical dimensions (0.370" L x 0.189" W) and lead spacing (0.142" / 3.60mm). Maximum seated height is identical at 0.339" (8.60mm). Both parts are compatible with the same through-hole radial footprint.

Q: Which part should I select based on current inventory?

A: CD10ED330JO3 has higher inventory availability (1142 units in stock) compared to CM04ED330JO3 (788 units in stock). Selection may be based on supply chain requirements and lead time considerations. Both parts are Active status and available for immediate procurement.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts maintain identical capacitance (33 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), and operating temperature range (-55°C ~ 125°C). Electrical performance is equivalent across all specified parameters.
