CMR03C2R0DOCM Equivalent & Substitute Parts

Part Overview

The CMR03C2R0DOCM is a 2 pF mica capacitor rated for 300 V operation in a radial through-hole package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance values with tight tolerance specifications. Mica capacitors in this value range are used in RF circuits, timing networks, and precision filtering applications where the dielectric stability and low loss characteristics of mica are essential. Identifying equivalent substitute parts becomes necessary when managing inventory constraints, addressing supply chain disruptions, or consolidating component procurement across multiple design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMR03C2R0DOCM is determined by strict equivalence across the following critical parameters:

Capacitance Value: 2 pF (exact match required)

Capacitance Tolerance: ±0.5 pF (exact match required)

Voltage Rating: 300 V (minimum requirement; higher ratings are acceptable)

Dielectric Material: Mica (required for performance characteristics)

Mounting Configuration: Through Hole, Radial package with 0.118" (3.00 mm) lead spacing (physical compatibility requirement)

Operating Temperature Range: -55°C to 125°C (minimum requirement; extended ranges are acceptable)

Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory requirement)

The substitute part CD5CC020DO3F meets all substitution criteria through identical electrical specifications, mechanical dimensions, and regulatory compliance status. Both components are manufactured by Cornell Dubilier Electronics and share the same dielectric material, package geometry, and environmental performance envelope.

Both components satisfy identical regulatory and compliance requirements and are suitable for direct substitution in applications requiring 2 pF mica capacitors at 300 V with ±0.5 pF tolerance.

Frequently Asked Questions (FAQ)

Q: Can CD5CC020DO3F be used as a direct replacement for CMR03C2R0DOCM?

A: Yes. The CD5CC020DO3F is a direct electrical and mechanical equivalent. Both components share identical capacitance values, tolerance specifications, voltage ratings, dielectric materials, operating temperature ranges, and physical package dimensions. No circuit modifications or board layout adjustments are required.

Q: Are there any differences in the radial package configuration between these parts?

A: No. Both components feature identical radial through-hole packages with 0.118" (3.00 mm) lead spacing, 0.272" L x 0.110" W body dimensions, and 0.189" maximum seated height. PCB footprints and mounting hole spacing are identical.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both CMR03C2R0DOCM and CD5CC020DO3F are ROHS3 compliant and REACH unaffected. They carry identical environmental and regulatory certifications.

Q: What is the difference between the CMR and CD5 series designations?

A: The series designation reflects the internal product line classification within Cornell Dubilier Electronics. The CMR03C2R0DOCM belongs to the CMR series, while the CD5CC020DO3F belongs to the CD5 series. Despite different series names, both components meet identical electrical and mechanical specifications for this 2 pF, 300 V mica capacitor application.

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

A: No. Both components operate across the identical temperature range of -55°C to 125°C and are constructed from mica dielectric material, which provides equivalent frequency response and temperature stability characteristics.

Q: Can these parts be mixed in the same circuit board assembly?

A: Yes. Since both components are electrically and mechanically identical, they can be used interchangeably within the same assembly or across multiple production batches without affecting circuit performance or reliability.
