CD42FC623JO3 Equivalent & Substitute Parts

Part Overview

The CD42FC623JO3 is a 0.062 µF mica capacitor rated for 300 V operation in a radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active and currently in production. The CD42 series represents a general-purpose mica capacitor line designed for applications requiring stable capacitance values across wide temperature ranges and high voltage environments.

Identification of equivalent and substitute parts becomes necessary when the primary part number experiences supply constraints, when design revisions require updated compliance certifications, or when inventory management requires sourcing from alternative stock positions while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD42FC623JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.062 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 300 V (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 27.00 mm (exact match required)
• Physical dimensions: 37.30 mm L × 11.40 mm W × 23.40 mm H maximum seated height (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

The CD42FC623JO3F qualifies as a parametric equivalent because it maintains identical electrical specifications, mechanical configuration, and environmental performance characteristics. The primary distinction between these part numbers relates to regulatory compliance status rather than functional performance.

Parameter Comparison

Engineering Selection Recommendations

CD42FC623JO3: This part number is active and available with current inventory of 838 pieces. Selection of this part is appropriate for applications where RoHS non-compliant components are acceptable and REACH-affected materials are permissible under project specifications.

CD42FC623JO3F: This part number is active and available with current inventory of 931 pieces. Selection of this part is appropriate for applications requiring ROHS3 compliance certification and REACH-unaffected material status. The "F" suffix designation indicates updated regulatory compliance. This part number is suitable for designs subject to European Union environmental directives or customer specifications mandating RoHS3 compliance.

Both part numbers are functionally and mechanically interchangeable. Selection between them depends solely on regulatory compliance requirements applicable to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Are CD42FC623JO3 and CD42FC623JO3F electrically identical?

A: Yes. Both part numbers deliver identical electrical performance: 0.062 µF capacitance at ±5% tolerance, 300 V rated voltage, mica dielectric, and -55°C to 125°C operating temperature range.

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts feature identical radial through-hole configuration with 27.00 mm lead spacing and matching physical dimensions (37.30 mm L × 11.40 mm W × 23.40 mm H maximum seated height). Direct substitution in PCB layouts is possible without modification.

Q: What is the difference between these part numbers?

A: The primary difference is regulatory compliance status. CD42FC623JO3F carries ROHS3 compliance certification and REACH-unaffected material status, while CD42FC623JO3 does not. Electrical and mechanical specifications are identical.

Q: Which part should I select for new designs?

A: Selection depends on project compliance requirements. If ROHS3 compliance or REACH-unaffected status is required, select CD42FC623JO3F. If these certifications are not required, either part number is acceptable based on availability and cost considerations.

Q: Can I substitute CD42FC623JO3 with CD42FC623JO3F in existing designs?

A: Yes, provided the design does not explicitly prohibit RoHS3-compliant components or REACH-unaffected materials. No circuit modifications or PCB layout changes are required.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical capacitance stability, voltage performance, and temperature characteristics across the specified operating range.
