CD15FD331FO3 Equivalent & Substitute Parts

Part Overview

The CD15FD331FO3 is a 330 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 863 pieces available in new original stock.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, inventory depletion occurs, or when design requirements mandate compliance with specific regulatory standards such as RoHS3 certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD15FD331FO3 is determined by strict equivalence across all electrical and mechanical parameters. The critical parameters that define substitutability are:

• Capacitance Value: 330 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Physical Dimensions: Lead spacing 0.232" (5.90 mm), body dimensions 0.469" L x 0.209" W (11.90 mm x 5.30 mm), height 0.390" (9.90 mm) (exact match required)

The substitute part CD15FD331FO3F meets all these parameters identically, establishing it as a parametric equivalent within the CD15 series.

Parameter Comparison

Engineering Selection Recommendations

CD15FD331FO3F is the parametric equivalent substitute for CD15FD331FO3. Both parts are manufactured by Cornell Dubilier Electronics within the CD15 series and maintain identical electrical and mechanical specifications.

The primary distinction between these parts lies in regulatory compliance status:

• CD15FD331FO3: RoHS non-compliant, REACH Affected
• CD15FD331FO3F: 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 or REACH compliance exemption must use CD15FD331FO3F. Applications without such regulatory constraints may use either part. The CD15FD331FO3F variant also offers significantly higher inventory availability (3010 pieces versus 863 pieces).

Frequently Asked Questions (FAQ)

Q: Can CD15FD331FO3F be used as a direct replacement for CD15FD331FO3?

A: Yes. Both parts are parametric equivalents with identical capacitance (330 pF), tolerance (±1%), voltage rating (500 V), dielectric material (mica), temperature range (-55°C to 125°C), mounting type (through hole radial), and physical dimensions. Direct substitution is electrically and mechanically compatible.

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

A: The parts differ in regulatory compliance status. CD15FD331FO3F is ROHS3 Compliant and REACH Unaffected, while CD15FD331FO3 is RoHS non-compliant and REACH Affected. All electrical and mechanical parameters are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance exemption, use CD15FD331FO3F. Both parts are active in production and suitable for new designs.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: 0.469" L x 0.209" W (11.90 mm x 5.30 mm) body size, 0.390" (9.90 mm) maximum seated height, and 0.232" (5.90 mm) lead spacing. PCB layout and mechanical fit are identical.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. The identical electrical specifications (330 pF, ±1%, 500 V), temperature range (-55°C to 125°C), and physical dimensions ensure complete interchangeability in existing circuit designs and PCB layouts.

Q: What is the lead spacing for these capacitors?

A: The lead spacing is 0.232 inches (5.90 millimeters) for both parts, measured center-to-center between the radial leads.
