CD19FD472FO3 Mica Capacitor 4700 pF 500 V Radial

Part Overview

The CD19FD472FO3 is a 4700 pF mica capacitor rated for 500 V with ±1% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as a general-purpose through-hole radial capacitor designed for applications requiring high stability and low loss characteristics inherent to mica dielectric technology. The part maintains active product status within the CD19 series. Identification of equivalent and substitute parts becomes necessary when primary inventory availability is limited or when compliance requirements differ between procurement specifications and application environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FD472FO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical capacitance value (4700 pF), tolerance specification (±1%), rated voltage (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting configuration (through-hole radial), lead spacing (0.343" / 8.70 mm), and physical envelope dimensions (0.701" L × 0.350" W, height 0.579" maximum).

The CD19FD472FO3F qualifies as a parametric equivalent based on complete alignment with these core specifications. Both parts belong to the CD19 series and share identical electrical performance characteristics and mechanical form factors. Differentiation between the main part and its substitute is limited to regulatory compliance status and inventory availability, not functional or dimensional parameters.

Engineering Selection Recommendations

The CD19FD472FO3 and CD19FD472FO3F are functionally and mechanically interchangeable for circuit applications requiring a 4700 pF mica capacitor at 500 V with ±1% tolerance and through-hole radial mounting.

Selection between these parts is determined by regulatory and compliance requirements:

CD19FD472FO3 is appropriate for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. Current inventory availability is 842 pieces.

CD19FD472FO3F is required for applications subject to ROHS3 compliance mandates and REACH-unaffected material specifications. This variant provides enhanced regulatory alignment for modern procurement environments. Current inventory availability is 6396 pieces.

Both parts maintain identical electrical performance, temperature stability, and mechanical compatibility. Selection should be based solely on applicable regulatory requirements and inventory availability for the specific application environment.

Frequently Asked Questions (FAQ)

Q: Can CD19FD472FO3F be used as a direct replacement for CD19FD472FO3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The CD19FD472FO3F can be substituted directly without circuit modification or re-qualification, provided that ROHS3 compliance and REACH-unaffected material status do not conflict with existing design specifications.

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

A: The parts are identical in capacitance (4700 pF), tolerance (±1%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through-hole radial), lead spacing (0.343" / 8.70 mm), and physical dimensions. The differences are limited to RoHS compliance status (non-compliant versus ROHS3 compliant) and REACH material classification (affected versus unaffected).

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts share identical lead spacing of 0.343" (8.70 mm), physical dimensions of 0.701" L × 0.350" W (17.80 mm × 8.90 mm), and maximum seated height of 0.579" (14.70 mm). No PCB layout modifications are required when substituting between these parts.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance and REACH-unaffected material sourcing, specify CD19FD472FO3F. For applications without these compliance mandates, either part is acceptable based on availability and cost considerations.

Q: Is there any difference in electrical performance or reliability?

A: No. Both parts deliver identical electrical performance, temperature stability, and reliability characteristics. Differences are regulatory and material sourcing only.
