CMR03C1R0DOCM Equivalent & Substitute Parts

Part Overview

The CMR03C1R0DOCM is a 1 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 across a wide operating temperature range of -55°C to 125°C. Substitute parts are identified when inventory constraints, compliance requirements, or specific application needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMR03C1R0DOCM are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters:

• Capacitance value: 1 pF
• Tolerance: ±0.5 pF
• Voltage rating: 300 V
• Dielectric material: Mica

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.118" (3.00 mm)
• Physical dimensions: 0.272" L x 0.110" W (6.90 mm x 2.80 mm)
• Maximum seated height: 0.189" (4.80 mm)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts match these parameters exactly, ensuring direct functional and mechanical compatibility in circuit board layouts and electrical applications.

Engineering Selection Recommendations

CMR03C1R0DOCM (Primary Part)

The CMR03C1R0DOCM is the primary reference component. It carries ROHS3 compliance certification and REACH Unaffected status, making it suitable for applications subject to environmental and regulatory restrictions. Current inventory of 1056 pieces supports standard procurement cycles.

CD5CC010DO3F (Preferred Substitute)

The CD5CC010DO3F is the recommended substitute when CMR03C1R0DOCM availability is limited. This part maintains identical electrical and mechanical specifications while providing ROHS3 compliance and REACH Unaffected status matching the primary part. Higher inventory availability (1748 pieces) supports extended procurement windows. Selection of CD5CC010DO3F is appropriate for applications with regulatory compliance requirements.

CD5CC010DO3 (Alternative Substitute)

The CD5CC010DO3 provides electrical and mechanical equivalence but carries RoHS non-compliant status and REACH Affected classification. This part is suitable only for applications without regulatory compliance constraints or where legacy system requirements permit non-compliant components. Use of this part requires explicit verification of application compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can CD5CC010DO3F be used as a direct replacement for CMR03C1R0DOCM in production assemblies?

A: Yes. The CD5CC010DO3F matches all electrical parameters (1 pF capacitance, ±0.5 pF tolerance, 300 V rating), mechanical specifications (radial through-hole package, 0.118" lead spacing, identical physical dimensions), and environmental ratings (-55°C to 125°C operating range, MSL 1). Both parts carry ROHS3 compliance and REACH Unaffected status. Direct substitution is electrically and mechanically valid.

Q: What is the difference between CD5CC010DO3 and CD5CC010DO3F?

A: Both parts are electrically and mechanically identical. The primary difference is regulatory compliance: CD5CC010DO3F is ROHS3 compliant and REACH Unaffected, while CD5CC010DO3 is RoHS non-compliant and REACH Affected. Selection depends on application compliance requirements.

Q: Will these substitute parts fit existing PCB layouts designed for CMR03C1R0DOCM?

A: Yes. All substitute parts share identical lead spacing (0.118" / 3.00 mm), physical dimensions (0.272" L x 0.110" W / 6.90 mm x 2.80 mm), and maximum seated height (0.189" / 4.80 mm). PCB footprints and through-hole spacing require no modification.

Q: Are there any performance differences between the CMR03C1R0DOCM and its substitutes?

A: No. All parts are mica dielectric capacitors with identical capacitance (1 pF), tolerance (±0.5 pF), voltage rating (300 V), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent across all three part numbers.

Q: Which substitute should be selected for new designs?

A: CD5CC010DO3F is the appropriate selection for new designs. It provides full regulatory compliance (ROHS3, REACH Unaffected) matching the primary CMR03C1R0DOCM while maintaining complete electrical and mechanical equivalence.

Q: Can CD5CC010DO3 be used in applications requiring RoHS compliance?

A: No. CD5CC010DO3 carries RoHS non-compliant status and is not suitable for applications with regulatory compliance requirements. Use CD5CC010DO3F or CMR03C1R0DOCM for RoHS-compliant applications.
