CM07FD103FO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CM07FD103FO3 is a 10000 pF mica capacitor rated for 500 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 dielectric 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 become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative compliance certifications such as RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM07FD103FO3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 10000 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.437" / 11.10 mm (exact match required)
• Physical Dimensions: 0.799" L x 0.339" W / 20.30 x 8.60 mm (exact match required)
• Height - Seated (Max): 0.890" / 22.60 mm (exact match required)

The CD30FD103FO3F meets all mandatory matching parameters and qualifies as a parametric equivalent. Differences in series designation (CD30 versus CM07), RoHS compliance status, and REACH classification do not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

CM07FD103FO3 Selection Criteria:

• Select when RoHS non-compliant components are acceptable for the application
• Suitable for legacy designs or applications without RoHS compliance requirements
• Current inventory: 890 pieces available

CD30FD103FO3F Selection Criteria:

• Select when ROHS3 compliance is required by design specifications or regulatory requirements
• Select when REACH unaffected status is required for supply chain compliance
• Provides identical electrical and mechanical performance to CM07FD103FO3
• Current inventory: 974 pieces available
• Recommended for new designs requiring environmental compliance certifications

Both parts are active products from the same manufacturer and deliver equivalent performance in all electrical and mechanical parameters. Selection between them depends solely on compliance certification requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can CD30FD103FO3F be used as a direct replacement for CM07FD103FO3 in existing designs?

A: Yes. The CD30FD103FO3F is a direct parametric equivalent. All electrical specifications (capacitance, tolerance, voltage rating, temperature range) and mechanical specifications (package type, lead spacing, physical dimensions, mounting configuration) are identical. No circuit modifications or PCB layout changes are required.

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

A: The series designation reflects the product line within Cornell Dubilier Electronics' mica capacitor portfolio. Both CM07 and CD30 series use identical mica dielectric technology and construction methods. The series difference does not affect electrical performance or mechanical compatibility.

Q: Why does CD30FD103FO3F have ROHS3 compliance while CM07FD103FO3 does not?

A: RoHS compliance status reflects the manufacturing process and material sourcing practices used for each product line. The CD30 series incorporates manufacturing processes that meet ROHS3 requirements, while the CM07 series does not. Both parts contain the same functional capacitor element and deliver identical electrical performance.

Q: Are there any lead spacing or footprint differences between these parts?

A: No. Both CM07FD103FO3 and CD30FD103FO3F have identical lead spacing of 0.437 inches (11.10 mm) and identical physical dimensions of 0.799" L x 0.339" W (20.30 x 8.60 mm). They are footprint-compatible and require no PCB modifications.

Q: Which part should be selected for new product designs?

A: For new designs, CD30FD103FO3F is the recommended selection due to ROHS3 compliance and REACH unaffected status, which align with current environmental and regulatory standards. The part provides identical performance with enhanced compliance certifications.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts are electrically and mechanically equivalent. However, design documentation and bill of materials should specify the appropriate part number based on compliance requirements for the specific application or customer.
