CD10FD221JO3 Equivalent & Substitute Parts

Part Overview

The CD10FD221JO3 is a 220 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 are identified to address inventory availability, compliance requirements, or series preference while maintaining electrical and mechanical compatibility.

Mounting Type	Through Hole	Determines PCB assembly compatibility
Package / Case	Radial	Defines physical form factor and lead configuration
Lead Spacing	0.142" (3.60 mm)	Critical for PCB footprint compatibility
Physical Dimensions	0.390" L x 0.220" W (9.90 mm x 5.60 mm)	Ensures fit within board layout constraints
Height - Seated (Max)	0.382" (9.70 mm)	Determines clearance requirements in assembly

Substitute Part Grouping Explanation

Substitute parts for the CD10FD221JO3 are identified based on strict electrical and mechanical parameter matching. All substitute candidates maintain identical capacitance (220 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.142" / 3.60 mm), and physical dimensions (0.390" L x 0.220" W / 9.90 mm x 5.60 mm).

Substitution is permissible when these core parameters align across all candidates. Variations in compliance status (RoHS, REACH), series designation (CD10 versus CM04), or moisture sensitivity level do not affect electrical or mechanical interchangeability but may influence procurement decisions based on regulatory or environmental requirements.

Engineering Selection Recommendations

CD10FD221JO3F is electrically and mechanically identical to the primary part CD10FD221JO3 with the distinction of ROHS3 compliance and REACH unaffected status. Selection of CD10FD221JO3F is appropriate for applications subject to RoHS3 regulatory requirements or where REACH compliance is mandated. This part maintains the same electrical performance and physical compatibility while offering improved compliance posture.

CM04FD221JO3 is electrically and mechanically identical to the primary part with identical RoHS non-compliant and REACH affected status. The CM04 series designation indicates a different product line within Cornell Dubilier Electronics. This part is suitable for applications where series preference is not a constraint and where RoHS3 compliance is not required. Moisture sensitivity level is specified as 1 (Unlimited) compared to Not Applicable for the CD10 series, indicating different handling and storage protocols.

All three parts are active products with confirmed inventory availability. Selection between CD10FD221JO3 and CD10FD221JO3F depends on compliance requirements. Selection of CM04FD221JO3 is appropriate when series flexibility is permitted and higher inventory levels are advantageous.

Frequently Asked Questions (FAQ)

Q: Can CD10FD221JO3F be used as a direct replacement for CD10FD221JO3?

A: Yes. CD10FD221JO3F is electrically and mechanically identical to CD10FD221JO3. Both parts share identical capacitance (220 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.142" / 3.60 mm), and physical dimensions. The primary difference is RoHS3 compliance status of CD10FD221JO3F versus non-compliance of CD10FD221JO3.

Q: Can CM04FD221JO3 be used as a direct replacement for CD10FD221JO3?

A: Yes. CM04FD221JO3 is electrically and mechanically identical to CD10FD221JO3. Both parts share identical capacitance (220 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.142" / 3.60 mm), and physical dimensions. The series designation differs (CM04 versus CD10), but this does not affect electrical or mechanical compatibility.

Q: What is the significance of the moisture sensitivity level difference between CD10FD221JO3 and CM04FD221JO3?

A: CD10FD221JO3 specifies moisture sensitivity level as Not Applicable, while CM04FD221JO3 specifies MSL 1 (Unlimited). This indicates different handling and storage protocols. MSL 1 (Unlimited) means the component has no moisture sensitivity restrictions and does not require special dry-pack storage or floor-life management. The Not Applicable designation for CD10FD221JO3 indicates mica capacitors in this series do not require moisture sensitivity classification. Both designations reflect the inherent moisture resistance of mica dielectric capacitors.

Q: Are there any PCB layout considerations when substituting between these parts?

A: No. All three parts maintain identical lead spacing (0.142" / 3.60 mm), physical dimensions (0.390" L x 0.220" W / 9.90 mm x 5.60 mm), and maximum seated height (0.382" / 9.70 mm). PCB footprints and assembly clearances are identical across all substitute candidates.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 regulatory requirements, CD10FD221JO3F is the appropriate selection. For applications without RoHS3 compliance mandates, CD10FD221JO3 or CM04FD221JO3 are suitable. All three parts are active products with confirmed inventory availability.
