CM05FD241FO3 Equivalent & Substitute Parts

Part Overview

The CM05FD241FO3 is a 240 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 a general-purpose mica capacitor with ±1% tolerance and operates across the temperature range of -55°C to 125°C. The part maintains Active product status and is available in bulk packaging with 969 pieces in current inventory.

Mica capacitors are essential in applications requiring high stability, low loss, and reliable performance across wide temperature ranges. Equivalent and substitute parts become necessary when addressing supply chain constraints, inventory optimization, or when alternative series offerings provide identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution of the CM05FD241FO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 240 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500 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: 0.232" / 5.90mm (exact match required)
• Physical dimensions: 0.461" L x 0.201" W / 11.70mm x 5.10mm (exact match required)

Environmental Parameters:

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

The CD15FD241FO3 meets all substitution criteria as a parametric equivalent within the Cornell Dubilier Electronics product portfolio, representing an alternative series designation while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CM05FD241FO3 and CD15FD241FO3 are Active products manufactured by Cornell Dubilier Electronics and carry identical compliance designations (REACH Affected, ECCN EAR99, HTSUS 8532.29.0020). Selection between these parts should be based on the following factors:

Inventory Availability: The CD15FD241FO3 maintains higher current inventory (1,243 pieces) compared to the CM05FD241FO3 (969 pieces), making it the preferred choice for applications requiring immediate procurement or larger volume orders.

Series Designation: The CM05 series represents the primary specification, while the CD15 series provides an equivalent alternative within the same manufacturer's portfolio. Both series employ identical mica dielectric technology and construction methods.

Compliance Considerations: Both parts are RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH restrictions require explicit verification of exemption applicability before component selection.

Moisture Sensitivity: The CM05FD241FO3 carries MSL 1 (Unlimited) classification, while the CD15FD241FO3 lists MSL as Not Applicable. This distinction does not affect substitution eligibility for general-purpose applications but should be noted for high-humidity storage or assembly environments.

Frequently Asked Questions (FAQ)

Q: Can the CD15FD241FO3 be used as a direct replacement for the CM05FD241FO3 in existing designs?

A: Yes. The CD15FD241FO3 is a parametric equivalent with identical electrical specifications (240 pF, ±1%, 500 V), dielectric material (mica), mounting configuration (radial through-hole), lead spacing (0.232" / 5.90mm), and physical dimensions (0.461" L x 0.201" W / 11.70mm x 5.10mm). Direct substitution is permissible without circuit redesign or PCB layout modification.

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

A: No performance differences exist between the CM05FD241FO3 and CD15FD241FO3. Both components operate across the identical temperature range (-55°C to 125°C), maintain ±1% tolerance, and are rated for 500 V operation. The difference is series designation only, reflecting alternative product lines within Cornell Dubilier Electronics' mica capacitor portfolio.

Q: What is the significance of the MSL rating difference?

A: The CM05FD241FO3 carries MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling. The CD15FD241FO3 lists MSL as Not Applicable, which is consistent with mica capacitor technology that inherently exhibits minimal moisture absorption. This difference does not affect substitution suitability for standard manufacturing environments.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the CM05FD241FO3 and CD15FD241FO3 are rated for continuous operation up to 125°C and maintain performance across the full -55°C to 125°C temperature range. Selection between these parts for temperature-critical applications should be based on inventory availability rather than thermal performance differences.

Q: What compliance considerations apply to these components?

A: Both parts are RoHS non-compliant and REACH Affected. Applications subject to RoHS Directive 2011/65/EU or REACH Regulation (EC) 1907/2006 require explicit verification of exemption applicability. Both components carry identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications for export control and tariff purposes.

Q: Can these parts be used interchangeably in high-frequency circuits?

A: Substitution is based on the provided electrical and mechanical parameters. Both components are specified as general-purpose mica capacitors with identical capacitance, tolerance, voltage rating, and dielectric material. Circuit-specific performance validation remains the responsibility of the design engineer.
