CM05FD241JO3 Equivalent & Substitute Parts

Part Overview

The CM05FD241JO3 is a 240 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE) in the CM05 series. This through-hole radial component is designed for general-purpose applications requiring high voltage stability and precision capacitance values. The part is currently active in production. Equivalent substitute parts are necessary to address inventory availability, compliance requirements, or manufacturing continuity across different product series within the same manufacturer portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM05FD241JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 240 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• 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, Height 0.382" max (exact match required)

All identified substitute parts meet these criteria. Variations in series designation (CM05 vs. CD15), RoHS compliance status, and REACH classification do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

CM05FD241JO3: Select this part number for applications where REACH Affected status is acceptable and RoHS non-compliance aligns with project requirements. Current inventory: 824 pcs.

CD15FD241JO3: This substitute provides identical electrical and mechanical specifications with equivalent REACH and RoHS status to the CM05FD241JO3. Use when CD15 series availability is preferred or when CM05 inventory is depleted. Current inventory: 4254 pcs.

CD15FD241JO3F: This substitute provides identical electrical and mechanical specifications with ROHS3 compliance and REACH Unaffected status. Select this part number for applications requiring RoHS3 compliance or REACH compliance. Current inventory: 1434 pcs.

All three parts are manufactured by Cornell Dubilier Electronics and maintain active product status. Selection between them should be based on regulatory compliance requirements and inventory availability rather than electrical performance, as all three are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can CD15FD241JO3 be used as a direct replacement for CM05FD241JO3?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance (240 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C ~ 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.232"), and physical dimensions. The difference in series designation (CM05 vs. CD15) does not affect interchangeability.

Q: What is the difference between CD15FD241JO3 and CD15FD241JO3F?

A: Both parts are electrically and mechanically identical. The primary differences are regulatory compliance: CD15FD241JO3 is RoHS non-compliant and REACH Affected, while CD15FD241JO3F is ROHS3 Compliant and REACH Unaffected. Select CD15FD241JO3F for applications requiring RoHS3 or REACH compliance.

Q: Are the physical dimensions identical across all three part numbers?

A: Yes. All three parts share identical dimensions: 0.461" L x 0.201" W (11.70mm x 5.10mm) with a maximum seated height of 0.382" (9.70mm). Lead spacing is 0.232" (5.90mm) for all three. They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: Which substitute should I select if RoHS compliance is required?

A: Select CD15FD241JO3F, which carries ROHS3 Compliant status. The other two part numbers (CM05FD241JO3 and CD15FD241JO3) are RoHS non-compliant.

Q: Can these parts be used in high-temperature applications?

A: Yes. All three parts are rated for operation across the temperature range -55°C ~ 125°C, making them suitable for high-temperature environments within this specification.

Q: Are there any differences in moisture sensitivity?

A: The CM05FD241JO3 has Moisture Sensitivity Level (MSL) 1 (Unlimited). The CD15FD241JO3 and CD15FD241JO3F both list MSL as Not Applicable. This does not affect electrical performance or interchangeability.
