CD42FD223JO3F Equivalent & Substitute Parts

Part Overview

The CD42FD223JO3F is a 0.022 µF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as active product status and is designed 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 performance across extended temperature ranges from -55°C to 125°C. Substitute parts are identified when inventory constraints, compliance requirements, or specific application needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD42FD223JO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 0.022 µF
• Tolerance: ±5%
• Voltage rating: 500 V
• Dielectric material: Mica

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 1.063" (27.00 mm)

Performance Parameters:

• Operating temperature range: -55°C to 125°C

The CD42FD223JO3 qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, dielectric material, mechanical configuration, and thermal operating range. Substitution is valid based on these matching parameters. Compliance status differences (RoHS and REACH) are noted but do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Selection: CD42FD223JO3F

The CD42FD223JO3F is the recommended primary choice for new designs and applications where regulatory compliance is a requirement. This part carries ROHS3 compliance certification and REACH Unaffected status, meeting current environmental and hazardous substance restrictions applicable to electronic components in regulated markets.

Substitute Selection: CD42FD223JO3

The CD42FD223JO3 serves as a functional equivalent for applications where compliance certifications are not mandated or where legacy system maintenance requires component matching with existing inventory. This part is electrically and mechanically identical to the primary part but carries RoHS non-compliant and REACH Affected designations. Selection of this substitute is appropriate only when:

• Replacement of existing CD42FD223JO3 components in operational systems
• Applications in non-regulated environments
• Inventory availability constraints require alternative sourcing
• Cost considerations override compliance requirements

Both parts maintain identical electrical performance, thermal stability, and mechanical compatibility. The choice between them is determined by regulatory environment and compliance obligations rather than technical performance factors.

Frequently Asked Questions (FAQ)

Q: Can CD42FD223JO3 be used as a direct replacement for CD42FD223JO3F in new designs?

A: CD42FD223JO3 is electrically and mechanically equivalent to CD42FD223JO3F. However, new designs should specify CD42FD223JO3F due to its ROHS3 compliance and REACH Unaffected status. Use CD42FD223JO3 only when compliance certifications are not applicable to the end application.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both CD42FD223JO3F and CD42FD223JO3 share identical dimensions: 1.421" L x 0.311" W (36.10 mm x 7.90 mm), with maximum seated height of 0.882" (22.40 mm). Lead spacing is 1.063" (27.00 mm) for both parts, ensuring identical PCB footprint compatibility.

Q: What is the difference between these two part numbers?

A: The primary differences are regulatory compliance certifications. CD42FD223JO3F is ROHS3 compliant and REACH Unaffected, while CD42FD223JO3 is RoHS non-compliant and REACH Affected. All electrical and mechanical specifications are identical.

Q: Can these parts be intermixed in the same circuit board assembly?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (0.022 µF), tolerance (±5%), voltage rating (500 V), and physical configuration. However, mixing parts with different compliance statuses may create documentation and traceability issues in regulated manufacturing environments.

Q: What is the lead spacing specification, and why is it important?

A: Lead spacing is 1.063" (27.00 mm) for both parts. This specification defines the distance between the two radial leads and determines PCB hole pattern compatibility. Identical lead spacing ensures both parts fit the same through-hole footprint without modification.

Q: Are there any temperature performance differences between these substitutes?

A: No. Both CD42FD223JO3F and CD42FD223JO3 operate across the identical temperature range of -55°C to 125°C with equivalent performance characteristics across this envelope.

Q: Which part should be specified for medical device applications?

A: CD42FD223JO3F should be specified for medical device applications due to its ROHS3 compliance certification. Medical device regulations typically require components meeting current environmental and hazardous substance restrictions.
