CMR03F101JOCP Equivalent & Substitute Parts

Part Overview

The CMR03F101JOCP is a 100 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 and suitable for general-purpose applications requiring stable capacitance and high voltage performance. Mica capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Substitute parts are identified to address inventory availability, compliance requirements, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMR03F101JOCP is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 100 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 300 V (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.118" / 3.00 mm (exact match required)
• Physical dimensions: 0.272" L x 0.181" W / 6.90 mm x 4.60 mm (exact match required)
• Maximum seated height: 0.240" / 6.10 mm (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

The identified substitute parts CD5FC101JO3 and CD5FC101JO3F satisfy all electrical, mechanical, and environmental parameters. Differences in compliance certifications (RoHS status, REACH status) and series designation (CD5 vs. CMR) do not affect functional substitution but may impact regulatory or procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

CMR03F101JOCP (Primary Part)

The CMR03F101JOCP is the primary specification. It carries ROHS3 compliance and REACH Unaffected status, making it suitable for applications subject to environmental regulations in the European Union and other regions with equivalent requirements. Moisture Sensitivity Level 1 indicates unlimited shelf life without special storage conditions.

CD5FC101JO3F (Preferred Substitute)

The CD5FC101JO3F is the recommended substitute when CMR03F101JOCP availability is constrained. It matches all electrical and mechanical parameters and carries identical compliance certifications: ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level 1 provides equivalent storage characteristics. The CD5 series designation indicates a different product line within Cornell Dubilier Electronics, but functional equivalence is complete.

CD5FC101JO3 (Alternative Substitute)

The CD5FC101JO3 is functionally equivalent in all electrical and mechanical parameters but differs in compliance status. It is RoHS non-compliant and REACH Affected. This part is suitable only for applications where regulatory compliance is not a requirement or where legacy equipment specifications explicitly permit non-compliant components. Moisture Sensitivity Level is listed as Not Applicable, which may indicate different handling or storage protocols compared to the primary part.

Frequently Asked Questions (FAQ)

Q: Can CD5FC101JO3 and CD5FC101JO3F be used interchangeably with CMR03F101JOCP?

A: Both substitute parts are electrically and mechanically equivalent. CD5FC101JO3F is directly interchangeable with no restrictions. CD5FC101JO3 is functionally equivalent but carries different compliance certifications; use is restricted to applications where RoHS and REACH compliance are not mandated.

Q: What is the difference between CD5FC101JO3 and CD5FC101JO3F?

A: Both parts are identical in electrical and mechanical specifications. The primary difference is compliance status: CD5FC101JO3F is ROHS3 Compliant and REACH Unaffected, while CD5FC101JO3 is RoHS non-compliant and REACH Affected. For new designs and regulated applications, CD5FC101JO3F is the appropriate selection.

Q: Will these substitute parts fit the same PCB footprint as CMR03F101JOCP?

A: Yes. All three parts share identical lead spacing (0.118" / 3.00 mm), physical dimensions (0.272" L x 0.181" W / 6.90 mm x 4.60 mm), and maximum seated height (0.240" / 6.10 mm). PCB layout compatibility is complete.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. All three parts operate across the identical temperature range (-55°C to 125°C) and carry the same 300 V voltage rating. Electrical performance characteristics remain unchanged.

Q: What does Moisture Sensitivity Level 1 mean for CD5FC101JO3?

A: CD5FC101JO3 lists MSL as Not Applicable, which differs from the CMR03F101JOCP and CD5FC101JO3F (both MSL 1 / Unlimited). This indicates different moisture handling protocols may apply; consult the manufacturer datasheet for specific storage and handling requirements.

Q: Can I use these parts in high-frequency applications?

A: Mica capacitors in this specification are suitable for general-purpose applications. Frequency performance characteristics are not provided in the parametric data. Application-specific frequency response requirements must be evaluated against manufacturer datasheets.
