CD15FD471FO3 Equivalent & Substitute Parts

Part Overview

The CD15FD471FO3 is a 470 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 813 units in stock.

Mica capacitors in this specification are essential for applications requiring high stability, low loss, and reliable performance in RF, timing, and precision filtering circuits. Identifying equivalent and substitute parts is necessary when managing inventory constraints, addressing supply chain variations, or transitioning between RoHS compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD471FO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (470 pF), tolerance specification (±1%), and voltage rating (500 V) must be identical. The mica dielectric material is a defining characteristic of this component class and cannot be substituted with alternative dielectric types.

Mechanical Parameters: Through-hole mounting configuration, radial package orientation, lead spacing (0.232" / 5.90 mm), and physical dimensions (0.469" L x 0.220" W, height 0.402" max) must match to ensure PCB compatibility and assembly feasibility.

Environmental Parameters: Operating temperature range (-55°C to 125°C) must be maintained or exceeded.

Series Designation: Parts must belong to the CD15 series from Cornell Dubilier Electronics to ensure manufacturing consistency and performance characteristics.

Substitute parts identified in this reference meet all electrical, mechanical, and environmental criteria. Compliance certifications (RoHS, REACH, ECCN) may vary between equivalent parts and should be evaluated based on end-application requirements.

Engineering Selection Recommendations

CD15FD471FO3F as Primary Substitute:

The CD15FD471FO3F is a direct parametric equivalent to the CD15FD471FO3, with identical electrical, mechanical, and environmental specifications. Both parts are active products from Cornell Dubilier Electronics within the CD15 series.

The primary distinction between these parts is regulatory compliance status. The CD15FD471FO3F carries ROHS3 compliance certification, whereas the CD15FD471FO3 is RoHS non-compliant. Additionally, the CD15FD471FO3F is REACH Unaffected, compared to the REACH Affected status of the original part.

Selection between these equivalent parts should be based on end-application compliance requirements. Applications subject to RoHS3 directives or REACH regulations should specify the CD15FD471FO3F. Applications without such regulatory constraints may use either part interchangeably from a functional and mechanical standpoint.

Both parts share identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can CD15FD471FO3F be used as a direct replacement for CD15FD471FO3 in existing designs?

A: Yes. The CD15FD471FO3F is electrically and mechanically identical to the CD15FD471FO3. Both parts have the same capacitance (470 pF), tolerance (±1%), voltage rating (500 V), lead spacing (0.232" / 5.90 mm), and physical dimensions. PCB layouts and circuit designs require no modification for this substitution.

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

A: The primary differences are regulatory compliance certifications. The CD15FD471FO3F is ROHS3 compliant and REACH Unaffected, while the CD15FD471FO3 is RoHS non-compliant and REACH Affected. All electrical and mechanical parameters are identical.

Q: Which part should I specify for new designs?

A: Specify the CD15FD471FO3F for new designs. This part carries current RoHS3 compliance certification and REACH Unaffected status, aligning with current regulatory standards. The CD15FD471FO3 remains available for legacy applications or designs without regulatory compliance requirements.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate identically across the -55°C to 125°C temperature range and are rated for 500 V. No derating or performance differences exist between the two parts.

Q: What is the lead spacing, and does it affect PCB compatibility?

A: Both parts have a lead spacing of 0.232" (5.90 mm). This dimension is critical for PCB footprint design. Verify that your PCB layout accommodates this lead spacing before component placement.

Q: Can these mica capacitors be substituted with film or ceramic capacitors?

A: No. Mica capacitors have distinct electrical characteristics including low loss, high stability, and superior frequency response compared to film or ceramic dielectrics. Substitution with alternative dielectric materials is not equivalent and may compromise circuit performance.

Q: What inventory levels are available for each part?

A: CD15FD471FO3 has 813 units in stock. CD15FD471FO3F has 1303 units in stock. Both are classified as new original components.
