CD15ED220DO3 Equivalent & Substitute Parts

Part Overview

The CD15ED220DO3 is a 22 pF mica capacitor rated for 500 V operation in a radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active and suitable for general-purpose applications requiring stable capacitance values with tight tolerance specifications. Mica dielectric capacitors are selected for applications demanding high reliability, low loss, and stable performance across extended temperature ranges from -55°C to 125°C. Identification of equivalent substitute parts becomes necessary when managing inventory constraints, addressing supply chain variations, or accommodating specific compliance requirements such as RoHS status.

Substitute Part Grouping Explanation

Substitution eligibility for the CD15ED220DO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically to establish a valid substitute relationship:

• Capacitance value: 22 pF
• Tolerance specification: ±0.5 pF
• Rated voltage: 500 V
• Dielectric material: Mica
• Operating temperature range: -55°C to 125°C
• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.232" (5.90 mm)
• Series designation: CD15

The CD15ED220DO3F qualifies as a parametric equivalent substitute because it maintains identical electrical performance and mechanical compatibility across all specified parameters. Differences in RoHS compliance status and REACH classification do not affect functional interchangeability but may influence procurement decisions based on regulatory requirements.

Engineering Selection Recommendations

The CD15ED220DO3F serves as a direct functional substitute for the CD15ED220DO3 in applications where electrical and mechanical specifications are the primary selection criteria. Both components are active products from the same manufacturer and series, ensuring design continuity and performance equivalence.

Selection between these two parts should be based on regulatory compliance requirements:

• CD15ED220DO3: Select when RoHS non-compliance is acceptable or when REACH-affected status does not conflict with procurement specifications.

• CD15ED220DO3F: Select when ROHS3 compliance is mandated or when REACH-unaffected status is required by regulatory frameworks or customer specifications.

Both parts maintain identical electrical performance, mechanical fit, and thermal operating characteristics. The choice between them does not affect circuit functionality, PCB layout, or thermal management considerations.

Frequently Asked Questions (FAQ)

Q: Can CD15ED220DO3F be used as a direct replacement for CD15ED220DO3 in existing designs?

A: Yes. The CD15ED220DO3F is electrically and mechanically identical to the CD15ED220DO3. All critical parameters including capacitance, tolerance, voltage rating, temperature range, and physical dimensions are equivalent. Direct substitution in PCB layouts and circuit designs is supported without modification.

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

A: The primary differences are RoHS compliance status and REACH classification. The CD15ED220DO3 is RoHS non-compliant and REACH-affected, while the CD15ED220DO3F is ROHS3 compliant and REACH-unaffected. Electrical and mechanical specifications are identical.

Q: Are there any lead spacing or mounting differences between these parts?

A: No. Both parts feature identical lead spacing of 0.232" (5.90 mm) and radial through-hole mounting configuration. PCB footprints and assembly processes remain unchanged.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements applicable to the end application. For designs subject to RoHS3 or REACH compliance mandates, the CD15ED220DO3F is the appropriate choice. For applications without such constraints, either part is functionally equivalent.

Q: Is there a performance difference in temperature stability or capacitance tolerance?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C and maintain the same capacitance tolerance of ±0.5 pF. Temperature coefficient and stability characteristics are equivalent.

Q: Can these parts be mixed in the same production batch?

A: Yes, from a functional perspective. However, procurement and quality assurance processes should verify that mixing aligns with regulatory compliance documentation and traceability requirements for the specific application.
