CMR03C2R0DOCR Equivalent & Substitute Parts

Part Overview

The CMR03C2R0DOCR 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 utilized in RF circuits, precision timing networks, and high-reliability applications where temperature stability and low dielectric loss are critical performance factors. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when design flexibility permits equivalent component selection.

Parameter Comparison

Engineering Selection Recommendations

The CD5CC020DO3F is a direct parametric equivalent to the CMR03C2R0DOCR. Both components are manufactured by Cornell Dubilier Electronics and share identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

Both parts maintain Active product status, ensuring continued availability and manufacturer support. Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. The identical operating temperature range (-55°C to 125°C) and Moisture Sensitivity Level (1 - Unlimited) confirm compatibility in equivalent applications.

The primary distinction is series designation: CMR versus CD5. This reflects different product lines within the CDE mica capacitor portfolio. The CD5CC020DO3F may be selected as a substitute when CMR03C2R0DOCR inventory is constrained, provided circuit design permits cross-series component substitution.

Frequently Asked Questions (FAQ)

Q: Can the CD5CC020DO3F be used as a direct replacement for the CMR03C2R0DOCR?

A: Yes. Both components share identical capacitance (2 pF), tolerance (±0.5 pF), voltage rating (300 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), and mechanical dimensions. Radial through-hole mounting with 0.118" (3.00 mm) lead spacing is identical. Both are ROHS3 Compliant with MSL 1 rating.

Q: Are there any differences in performance between these two parts?

A: No performance differences exist within the specified parameters. Both components are manufactured by Cornell Dubilier Electronics and meet identical electrical and mechanical specifications. Series designation (CMR versus CD5) reflects product line organization but does not affect functional performance in applications requiring 2 pF, 300 V mica capacitors.

Q: Will the CD5CC020DO3F fit the same PCB footprint as the CMR03C2R0DOCR?

A: Yes. Both components have identical physical dimensions (0.272" L x 0.110" W / 6.90 mm x 2.80 mm), maximum seated height (0.189" / 4.80 mm), and lead spacing (0.118" / 3.00 mm). PCB layout and footprint design require no modification.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the CMR03C2R0DOCR and CD5CC020DO3F are ROHS3 Compliant and REACH Unaffected. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the tolerance specification for these capacitors?

A: Both components carry a tolerance of ±0.5 pF. This tolerance applies to the 2 pF nominal capacitance value, resulting in an acceptable range of 1.5 pF to 2.5 pF.

Q: Can these capacitors be used in high-temperature applications?

A: Yes. Both components are rated for continuous operation across the temperature range of -55°C to 125°C. This range supports applications requiring thermal stability across industrial and aerospace temperature extremes.
