CD15FD431FO3 Equivalent & Substitute Parts

Part Overview

The CD15FD431FO3 is a 430 pF mica capacitor rated for 500 V with ±1% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component operates across the temperature range of -55°C to 125°C and is classified as a general-purpose capacitor. The part is currently active in production with 944 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints occur, or when design requirements necessitate alternative compliance certifications such as RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD15FD431FO3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match the following criteria:

• Capacitance value: 430 pF
• Tolerance: ±1%
• Voltage rating: 500 V
• Dielectric material: Mica
• Mounting configuration: Through hole radial
• Lead spacing: 0.232" (5.90 mm)
• Physical dimensions: 0.469" L x 0.209" W (11.90 mm x 5.30 mm)
• Height seated maximum: 0.390" (9.90 mm)
• Operating temperature range: -55°C to 125°C

The CD15FD431FO3F meets all these electrical and mechanical requirements and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CD15FD431FO3 and CD15FD431FO3F are parametric equivalents with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and regulatory status.

The CD15FD431FO3F is the preferred substitute when RoHS3 compliance is required for the end application. This part carries RoHS3 certification and REACH unaffected status, making it suitable for applications subject to European Union environmental directives.

The CD15FD431FO3 remains suitable for applications where RoHS compliance is not mandated. Both parts are active products with current manufacturing status and adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Are CD15FD431FO3 and CD15FD431FO3F electrically identical?

A: Yes. Both parts have identical capacitance (430 pF), tolerance (±1%), voltage rating (500 V), dielectric material (mica), and operating temperature range (-55°C to 125°C).

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts have identical lead spacing of 0.232" (5.90 mm), physical dimensions of 0.469" L x 0.209" W (11.90 mm x 5.30 mm), and seated height of 0.390" (9.90 mm). They are mechanically interchangeable in through-hole radial mounting applications.

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

A: The primary difference is regulatory compliance. The CD15FD431FO3F is RoHS3 compliant and REACH unaffected, while the CD15FD431FO3 is RoHS non-compliant and REACH affected. Both are manufactured by Cornell Dubilier Electronics in the CD15 series.

Q: Can I use CD15FD431FO3F as a direct replacement for CD15FD431FO3?

A: Yes. The CD15FD431FO3F is a direct parametric equivalent and can be used as a substitute in any application where the CD15FD431FO3 is specified, provided that regulatory compliance requirements do not restrict the choice.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For applications requiring RoHS3 compliance or REACH compliance, use CD15FD431FO3F. For applications without these regulatory requirements, either part is acceptable based on availability and supply chain considerations.
