Substitute Part Grouping Explanation

Substitution eligibility for the CM07FD103GO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD30FD103GO3F qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Alignment:

• Capacitance value: 10000 pF (identical)
• Voltage rating: 500 V (identical)
• Tolerance: ±2% (identical)
• Dielectric material: Mica (identical)
• Operating temperature range: -55°C to 125°C (identical)

Mechanical Parameter Alignment:

• Mounting type: Through Hole (identical)
• Package configuration: Radial (identical)
• Lead spacing: 0.437" / 11.10 mm (identical)
• Physical dimensions: 0.799" L x 0.339" W / 20.30 mm x 8.60 mm (identical)
• Maximum seated height: 0.890" / 22.60 mm (identical)

Series Differentiation: The CM07FD103GO3 belongs to the CM07 series, while the substitute CD30FD103GO3F belongs to the CD30 series. Both series are manufactured by Cornell Dubilier Electronics and share identical performance specifications for this capacitance and voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The CD30FD103GO3F substitute part maintains complete electrical and mechanical equivalence to the CM07FD103GO3 across all functional parameters. Both components deliver identical capacitance, voltage rating, tolerance, temperature performance, and physical form factor. Direct substitution is supported by parametric equivalence without performance degradation.

Compliance Considerations:

A significant differentiation exists in regulatory compliance status. The CM07FD103GO3 is classified as RoHS non-compliant and REACH Affected. The CD30FD103GO3F is ROHS3 Compliant and REACH Unaffected. Selection between these parts depends on application regulatory requirements. Applications subject to RoHS3 or REACH compliance mandates must utilize the CD30FD103GO3F. Applications without such regulatory constraints may use either part based on availability and inventory management priorities.

Product Status:

Both parts maintain Active product status, confirming ongoing manufacturing support and supply chain availability through Cornell Dubilier Electronics.

Frequently Asked Questions (FAQ)

Q: Can the CD30FD103GO3F be used as a direct replacement for the CM07FD103GO3 in existing circuit designs?

A: Yes. The CD30FD103GO3F is a parametric equivalent with identical electrical specifications (10000 pF, 500 V, ±2% tolerance, mica dielectric) and mechanical configuration (radial through-hole, 0.437" lead spacing, identical dimensions). No circuit redesign or PCB layout modification is required.

Q: What is the difference between the CM07 and CD30 series?

A: Both series are manufactured by Cornell Dubilier Electronics and deliver identical performance for this 10000 pF, 500 V mica capacitor specification. The series designation reflects internal product line organization. Electrical and mechanical performance is equivalent.

Q: Does the RoHS3 compliance difference affect electrical performance?

A: No. RoHS3 compliance is a regulatory classification related to restricted substance content in manufacturing. It does not alter the electrical characteristics, capacitance value, voltage rating, tolerance, temperature performance, or dielectric properties of the component.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the CM07FD103GO3 and CD30FD103GO3F share identical dimensions: 0.799" L x 0.339" W (20.30 mm x 8.60 mm), maximum seated height of 0.890" (22.60 mm), and lead spacing of 0.437" (11.10 mm). PCB footprints are interchangeable.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 or REACH compliance requirements, select the CD30FD103GO3F. For applications without such regulatory mandates, either part is suitable. Consult application-specific compliance documentation to determine regulatory requirements.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C, ensuring equivalent thermal performance in all application environments.

Q: What is the lead spacing significance for PCB assembly?

A: Lead spacing of 0.437" (11.10 mm) defines the distance between component leads on the PCB. Both parts share this identical spacing, confirming direct footprint compatibility without PCB redesign.
