Substitute Part Grouping Explanation

Substitution of the CD15FD431JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 430 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.232" (5.90mm) (exact match required)
• Physical Dimensions: 0.469" L x 0.209" W, Height 0.390" max (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)

The CD15FD431JO3F is a parametric equivalent within the CD15 series that maintains identical electrical and mechanical specifications. The primary distinction between these parts lies in regulatory compliance certifications rather than functional performance.

Parameter Comparison

Engineering Selection Recommendations

CD15FD431JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. This part maintains active production status with adequate inventory availability.

CD15FD431JO3F is the appropriate selection for designs requiring ROHS3 compliance and REACH-unaffected component sourcing. This variant provides identical electrical and mechanical performance while meeting enhanced regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CD15FD431JO3 and CD15FD431JO3F be used interchangeably in circuit designs?

A: Yes. Both parts are parametric equivalents with identical capacitance (430 pF), tolerance (±5%), voltage rating (500 V), dielectric material (Mica), mounting type (Through Hole Radial), lead spacing (0.232"), physical dimensions, and operating temperature range (-55°C to 125°C). Electrical and mechanical performance are equivalent.

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

A: The primary differences are regulatory compliance certifications. CD15FD431JO3F is ROHS3 compliant and REACH unaffected, while CD15FD431JO3 is RoHS non-compliant and REACH affected. Electrical specifications and physical form factors are identical.

Q: Which part should be selected for new designs?

A: CD15FD431JO3F is recommended for new designs due to ROHS3 compliance and REACH-unaffected status, which align with current regulatory standards and reduce supply chain restrictions.

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

A: No. Both parts share identical lead spacing (0.232" / 5.90mm), physical dimensions (0.469" L x 0.209" W), and maximum seated height (0.390"). PCB footprints and mounting procedures are identical.

Q: What is the inventory status for each part?

A: CD15FD431JO3 has 911 units in stock. CD15FD431JO3F has 1093 units in stock. Both are available as new original components.
