Substitute Part Grouping Explanation

Substitution of the CM05FD221FO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 220 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 ~ 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 x 0.382" H max (exact match required)

The substitute part CD15FD221FO3F meets all electrical and mechanical parameters specified above. The primary distinction between the main part and its substitute relates to regulatory compliance status and product series designation.

Parameter Comparison

Engineering Selection Recommendations

Electrical and Mechanical Compatibility: The CD15FD221FO3F substitute part is electrically and mechanically equivalent to the CM05FD221FO3. Both components share identical capacitance, voltage rating, tolerance, dielectric material, temperature range, and physical dimensions. Direct substitution is permissible from a functional standpoint.

Regulatory Compliance Considerations: The CD15FD221FO3F offers enhanced regulatory compliance status. This substitute part is ROHS3 compliant and REACH unaffected, whereas the CM05FD221FO3 is RoHS non-compliant and REACH affected. Selection of the CD15FD221FO3F is appropriate for applications subject to RoHS or REACH regulatory requirements.

Product Series and Availability: The CM05FD221FO3 belongs to the CM05 series, while the CD15FD221FO3F belongs to the CD15 series. Both series are manufactured by Cornell Dubilier Electronics and maintain Active product status. The CD15FD221FO3F demonstrates higher current inventory availability (3636 pcs) compared to the CM05FD221FO3 (854 pcs).

Frequently Asked Questions (FAQ)

Q: Can the CD15FD221FO3F be used as a direct replacement for the CM05FD221FO3 in existing circuit designs?

A: Yes. The CD15FD221FO3F is electrically and mechanically equivalent. Both components have identical capacitance (220 pF), voltage rating (500 V), tolerance (±1%), operating temperature range (-55°C ~ 125°C), and physical dimensions. The radial through-hole package and lead spacing (0.232" / 5.90mm) are identical, permitting direct PCB substitution without layout modifications.

Q: What are the key differences between these two parts?

A: The primary differences are regulatory compliance status and product series designation. The CD15FD221FO3F is ROHS3 compliant and REACH unaffected, while the CM05FD221FO3 is RoHS non-compliant and REACH affected. The parts belong to different CDE product series (CD15 versus CM05) but maintain equivalent electrical and mechanical specifications.

Q: Should I select the CD15FD221FO3F over the CM05FD221FO3 for new designs?

A: Selection depends on regulatory requirements applicable to the end application. If RoHS or REACH compliance is mandated, the CD15FD221FO3F is the appropriate choice. Both parts are Active status and suitable for general-purpose applications. The CD15FD221FO3F also offers higher inventory availability.

Q: Are there any package or mounting differences between these capacitors?

A: No. Both the CM05FD221FO3 and CD15FD221FO3F are radial through-hole mica capacitors with identical physical dimensions (0.461" L x 0.201" W x 0.382" H max) and lead spacing (0.232" / 5.90mm). No PCB layout or mounting modifications are required for substitution.

Q: What is the moisture sensitivity level for these parts?

A: The CM05FD221FO3 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited). The CD15FD221FO3F lists MSL as Not Applicable. Both classifications indicate minimal moisture sensitivity, typical of mica dielectric capacitors.
