CMR03C2R0DOCP Equivalent & Substitute Parts

Part Overview

The CMR03C2R0DOCP is a 2 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 300 V operation in radial through-hole configuration. This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance values across wide temperature ranges. Mica capacitors of this specification are used in RF circuits, timing networks, and precision filtering applications where low capacitance values and tight tolerances are critical. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMR03C2R0DOCP is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2 pF (exact match required)
• Tolerance: ±0.5 pF (exact match required)
• Voltage rating: 300 V (minimum requirement; higher ratings acceptable)
• Dielectric material: Mica (required for performance characteristics)

Mechanical Parameters:

• Mounting type: Through Hole (required for PCB assembly compatibility)
• Package configuration: Radial (required for lead orientation and spacing)
• Lead spacing: 0.118" / 3.00 mm (required for footprint compatibility)
• Physical dimensions: 0.272" L x 0.110" W / 6.90 mm x 2.80 mm (required for board layout)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C (minimum requirement)
• RoHS3 compliance status (required for regulatory alignment)
• Moisture Sensitivity Level 1 (required for storage and handling)

The substitute part CD5CC020DO3F meets all specified criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CMR03C2R0DOCP and CD5CC020DO3F are Active product status components manufactured by Cornell Dubilier Electronics. Selection between these parts is based on availability and procurement logistics rather than technical differentiation.

CMR03C2R0DOCP (CMR Series):

• Current inventory: 813 pieces
• Recommended for primary procurement when available

CD5CC020DO3F (CD5 Series):

• Current inventory: 785 pieces
• Recommended as direct substitute when CMR series is unavailable

Both parts satisfy identical electrical specifications, mechanical compatibility, and regulatory compliance requirements (ROHS3 Compliant, REACH Unaffected). Selection does not require design modification, PCB layout changes, or performance re-evaluation. The parts are interchangeable at the component level for all applications requiring 2 pF, 300 V, ±0.5 pF tolerance mica capacitors in radial through-hole configuration.

Frequently Asked Questions (FAQ)
