CM05CD010DO3 Mica Capacitor – Equivalent & Substitute Parts

Part Overview

The CM05CD010DO3 is a 1 pF mica capacitor rated for 500 V, designed for through-hole radial mounting in general purpose applications. This part is currently active in production and maintains full inventory availability (961 pcs in stock). Mica capacitors are essential for high-frequency circuits, RF applications, and precision timing networks where low capacitance values with tight tolerances are required. Alternative equivalent models are necessary when the CM05 series is unavailable or when compliance requirements differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CM05CD010DO3 are qualified based on identical electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 1 pF (exact match required)
• Voltage rating: 500 V (exact match required)
• Tolerance: ±0.5 pF (exact match required)
• Dielectric material: Mica (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Mounting configuration: Through-hole radial (exact match required)
• Lead spacing: 0.232" (5.90 mm) (exact match required)
• Physical dimensions: 0.449" L × 0.169" W (exact match required)

The two substitute parts—CD15CD010DO3 and CD15CD010DO3F—meet all electrical and mechanical requirements for direct replacement. Both utilize the same CD15 series platform with identical capacitive characteristics, voltage handling capability, and thermal performance. The primary differentiator between substitutes is regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CM05CD010DO3, CD15CD010DO3, and CD15CD010DO3F—are functionally equivalent for applications requiring a 1 pF, 500 V mica capacitor with through-hole radial mounting. Selection between them is driven by regulatory and compliance requirements rather than electrical performance.

For RoHS3 Compliant Applications: Use CD15CD010DO3F. This part meets RoHS3 compliance standards and is not affected by REACH restrictions, making it the optimal choice for consumer electronics, automotive systems, and applications subject to environmental regulations.

For Legacy Systems or REACH-Compliant Applications: Use CD15CD010DO3 or CM05CD010DO3. Both maintain compatibility with existing designs. The CM05CD010DO3 is RoHS non-compliant and REACH-affected, while CD15CD010DO3 shares identical RoHS non-compliance but is also REACH-affected. These parts are appropriate for industrial, military, or aerospace applications where RoHS exemptions apply.

For Maximum Availability: CD15CD010DO3F provides the highest inventory level (1886 pcs), followed by CM05CD010DO3 (961 pcs) and CD15CD010DO3 (926 pcs).

Frequently Asked Questions (FAQ)

Q: Are CM05CD010DO3, CD15CD010DO3, and CD15CD010DO3F electrically interchangeable?

A: Yes. All three parts have identical capacitance (1 pF), voltage rating (500 V), tolerance (±0.5 pF), and temperature range (-55°C to 125°C). They are direct functional equivalents for all circuit applications.

Q: Can I use CD15CD010DO3F as a drop-in replacement for CM05CD010DO3?

A: Yes. The parts are mechanically and electrically identical. The primary difference is compliance status: CD15CD010DO3F is RoHS3 compliant and REACH unaffected, while CM05CD010DO3 is RoHS non-compliant and REACH-affected. Verify compliance requirements for your application before selection.

Q: What does "REACH Affected" versus "REACH Unaffected" mean?

A: REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) status indicates whether a component is subject to European chemical regulation requirements. REACH-affected parts may have restrictions on use in certain jurisdictions. REACH-unaffected parts (such as CD15CD010DO3F) have no such restrictions.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All parts measure 0.449" L × 0.169" W (11.40 mm × 4.30 mm) with a maximum seated height of 0.358" (9.10 mm) and lead spacing of 0.232" (5.90 mm). They mount identically in through-hole radial applications.

Q: Which substitute part should I select for new product designs?

A: CD15CD010DO3F is the recommended choice for new designs because it meets RoHS3 compliance and is not affected by REACH restrictions. This part supports compliance with current and future environmental regulations while maintaining full electrical and mechanical equivalence.

Q: Can I mix these parts within the same assembly?

A: Yes. Since all three parts are electrically and mechanically identical, they can be used interchangeably within the same PCB assembly. However, verify that your supply chain and compliance documentation can accommodate multiple part numbers if required for traceability.
