CD10CD010DO3 Equivalent & Substitute Parts Reference

Part Overview

The CD10CD010DO3 is a 1 pF mica capacitor rated for 500 V operation in a radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general-purpose applications requiring high-voltage, low-capacitance energy storage or filtering in electronic circuits.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design specifications permit selection from qualified alternatives that meet identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD10CD010DO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1 pF (exact match required)
• Capacitance Tolerance: ±0.5 pF (exact match required)
• Rated Voltage: 500 V (minimum requirement; higher ratings are acceptable)
• Dielectric Material: Mica (material type must match)
• Mounting Type: Through Hole (form factor must match)
• Package Configuration: Radial (lead configuration must match)
• Lead Spacing: 0.142" / 3.60 mm (mechanical compatibility requirement)
• Physical Dimensions: 0.360" L x 0.189" W / 9.15 mm x 4.80 mm (PCB layout compatibility)
• Operating Temperature Range: -55°C to 125°C (thermal operating envelope)

Parts meeting all these parameters are classified as parametric equivalents and may be selected interchangeably for the CD10CD010DO3 in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

CD10CD010DO3F is the qualified parametric equivalent for CD10CD010DO3. Both parts are manufactured by Cornell Dubilier Electronics within the CD10 series and share identical electrical and mechanical specifications.

Compliance Differentiation:

The CD10CD010DO3F carries ROHS3 compliance certification, whereas the CD10CD010DO3 is classified as RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the CD10CD010DO3F is the appropriate selection.

The CD10CD010DO3F is classified as REACH Unaffected, while the CD10CD010DO3 is REACH Affected. For supply chains requiring REACH compliance documentation, the CD10CD010DO3F eliminates REACH-related compliance obligations.

Both parts carry identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications, indicating equivalent export control and tariff treatment.

Inventory Availability:

CD10CD010DO3: 1,124 pieces in stock CD10CD010DO3F: 752 pieces in stock

Selection between these parts should be based on compliance requirements, inventory availability, and supply chain specifications rather than electrical or mechanical performance, as both parts are functionally identical.

Frequently Asked Questions (FAQ)

Q: Can CD10CD010DO3F be used as a direct replacement for CD10CD010DO3 in existing circuit designs?

A: Yes. The CD10CD010DO3F is a parametric equivalent with identical capacitance (1 pF), tolerance (±0.5 pF), voltage rating (500 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.142" / 3.60 mm), physical dimensions, and operating temperature range (-55°C to 125°C). No circuit redesign or PCB layout modification is required.

Q: What is the difference between CD10CD010DO3 and CD10CD010DO3F?

A: The electrical and mechanical specifications are identical. The primary differences are regulatory compliance status and inventory levels. CD10CD010DO3F is RoHS3 compliant and REACH Unaffected, while CD10CD010DO3 is RoHS non-compliant and REACH Affected. CD10CD010DO3 has higher current inventory (1,124 vs. 752 pieces).

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and are manufactured from mica dielectric material with identical specifications. No performance differentiation exists in thermal or frequency response.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For designs requiring RoHS compliance, specify CD10CD010DO3F. For designs without RoHS requirements, either part is acceptable based on availability and supply chain preferences.

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

A: Yes, provided the application does not mandate single-part-number consistency. Both parts are electrically and mechanically identical and will perform identically in circuit operation. Compliance documentation should reflect the specific part number used in each unit.

Q: What is the lead spacing tolerance for PCB design?

A: Lead spacing is 0.142" (3.60 mm) for both parts. PCB through-hole pad spacing should be designed to accommodate this specification with standard manufacturing tolerances.
