CD15FD511FO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD15FD511FO3 is a 510 pF mica capacitor rated for 500 V with ±1% tolerance, manufactured by Cornell Dubilier Electronics (CDE) in the CD15 series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance and high voltage performance across an operating temperature range of -55°C to 125°C. The part is currently active in production with 711 units in stock.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and mounting characteristics are maintained across the component family, enabling direct replacement in circuit designs without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD511FO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 510 pF (exact match required)
• Tolerance: ±1% (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" (5.90 mm) (exact match required)
• Physical Envelope: 0.469" L x 0.220" W x 0.402" H max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The CD15FD511FO3F qualifies as a parametric equivalent substitute because it maintains identical electrical and mechanical specifications across all critical parameters. Differences in regulatory compliance status (RoHS and REACH) do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CD15FD511FO3 and CD15FD511FO3F are active production components from Cornell Dubilier Electronics with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and compliance requirements applicable to the end application.

CD15FD511FO3 is suitable for applications where RoHS non-compliance and REACH-affected status are acceptable or where legacy component specifications are required.

CD15FD511FO3F is the appropriate selection for applications requiring ROHS3 compliance and REACH unaffected status. This variant maintains full functional equivalence while meeting enhanced environmental and regulatory standards.

Both parts share identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications. Inventory availability differs slightly: CD15FD511FO3 has 711 units in stock, while CD15FD511FO3F has 690 units in stock.

Frequently Asked Questions (FAQ)

Q: Can CD15FD511FO3F be used as a direct replacement for CD15FD511FO3 in existing designs?

A: Yes. The CD15FD511FO3F is a direct parametric equivalent with identical capacitance (510 pF), tolerance (±1%), 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). No circuit modifications or PCB layout changes are required.

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

A: The primary differences are regulatory compliance certifications. CD15FD511FO3F is ROHS3 compliant and REACH unaffected, while CD15FD511FO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts have identical physical dimensions of 0.469" L x 0.220" W (11.90 mm x 5.60 mm) with a maximum seated height of 0.402" (10.20 mm). Lead spacing is 0.232" (5.90 mm) for both variants.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance or REACH unaffected status, use CD15FD511FO3F. For applications without these requirements, either part is functionally equivalent.

Q: Do these parts have different temperature performance?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C with the same mica dielectric material and performance characteristics.

Q: Are the lead spacings compatible with standard 0.1" grid PCB layouts?

A: The lead spacing of 0.232" (5.90 mm) does not align with standard 0.1" (2.54 mm) grid spacing. PCB layouts must accommodate the specific 5.90 mm lead spacing for both CD15FD511FO3 and CD15FD511FO3F.
