CD15FD431GO3 Equivalent & Substitute Parts

Part Overview

The CD15FD431GO3 is a 430 pF mica capacitor rated for 500 V with ±2% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component operates across -55°C to 125°C and is classified as Active product status. Mica capacitors in this specification are used in general-purpose applications requiring stable capacitance and high voltage performance. Identifying equivalent substitute parts becomes necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when compliance requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD431GO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 430 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: 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)

The substitute part CD15FD431GO3F meets all these criteria and is classified as a parametric equivalent within the CD15 series from Cornell Dubilier Electronics.

Parameter Comparison

Engineering Selection Recommendations

The CD15FD431GO3F serves as a direct parametric equivalent to the CD15FD431GO3 across all electrical and mechanical specifications. Both parts are Active status products from Cornell Dubilier Electronics within the CD15 series.

The primary distinction between these parts lies in regulatory compliance:

• CD15FD431GO3: RoHS non-compliant, REACH Affected
• CD15FD431GO3F: ROHS3 Compliant, REACH Unaffected

Selection between these parts should be based on the regulatory requirements of the end application and target market. Applications requiring ROHS3 compliance and REACH compliance should specify CD15FD431GO3F. Applications without such regulatory constraints may use either part interchangeably from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can CD15FD431GO3F be used as a direct replacement for CD15FD431GO3?

A: Yes. Both parts are parametric equivalents with identical capacitance (430 pF), tolerance (±2%), voltage rating (500 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), mounting type (Through Hole), package configuration (Radial), lead spacing (0.232"), and physical dimensions. They are electrically and mechanically interchangeable.

Q: What is the difference between CD15FD431GO3 and CD15FD431GO3F?

A: The parts differ in regulatory compliance status. CD15FD431GO3F is ROHS3 Compliant and REACH Unaffected, while CD15FD431GO3 is RoHS non-compliant and REACH Affected. All other specifications are identical.

Q: Are these parts suitable for PCB assembly?

A: Both parts are through-hole radial components with 0.232" (5.90mm) lead spacing. They are compatible with standard through-hole PCB assembly processes. Physical dimensions are 0.469" L x 0.209" W with maximum seated height of 0.390".

Q: What applications use 430 pF mica capacitors rated at 500 V?

A: These capacitors are classified as general-purpose components. The 430 pF capacitance value and 500 V rating make them suitable for high-voltage circuits requiring stable capacitance across the -55°C to 125°C operating range.

Q: Is inventory availability a factor in part selection?

A: Current inventory shows CD15FD431GO3 at 694 pieces and CD15FD431GO3F at 1118 pieces. Availability may influence sourcing decisions, but both parts remain in stock.
