CD19FD911JO3 Equivalent & Substitute Parts

Part Overview

The CD19FD911JO3 is a 910 pF mica capacitor rated for 500 V with radial through-hole mounting, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active and suitable for general-purpose applications requiring stable capacitance and high voltage performance across extended temperature ranges (-55°C to 125°C).

Substitute parts are identified when electrical specifications, mechanical dimensions, and mounting characteristics remain identical or functionally equivalent. The primary reason for identifying substitutes is to ensure design continuity, support supply chain flexibility, and accommodate component availability variations across manufacturing batches and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD911JO3 is determined by strict equivalence across the following critical parameters:

Capacitance Value: 910 pF (exact match required)
Tolerance: ±5% (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: 0.343" (8.70 mm) (exact match required)
Physical Dimensions: 0.650" L x 0.209" W, Height 0.512" max (exact match required)
Series Classification: CD19 (exact match required)

Substitute parts must satisfy all parameters listed above to ensure direct interchangeability without circuit redesign, PCB layout modification, or performance degradation.

Engineering Selection Recommendations

CD19FD911JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. This part maintains active product status with established supply availability.

CD19FD911JO3F is the preferred selection for designs requiring ROHS3 compliance and REACH-unaffected material composition. Both parts are electrically and mechanically identical, with the primary distinction being regulatory compliance certifications. The CD19FD911JO3F variant provides enhanced compliance posture for regulated industries and export-controlled markets while maintaining identical electrical performance and physical interchangeability.

Selection between these parts depends on regulatory requirements applicable to the end application and geographic distribution channels rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Are CD19FD911JO3 and CD19FD911JO3F electrically interchangeable?

A: Yes. Both parts are identical in capacitance (910 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), and all electrical characteristics. They are direct electrical substitutes.

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts share identical physical dimensions (0.650" L x 0.209" W, 0.512" max height), lead spacing (0.343" / 8.70 mm), mounting type (through-hole radial), and package configuration. PCB layouts and mechanical assemblies require no modification.

Q: What is the difference between CD19FD911JO3 and CD19FD911JO3F?

A: The primary differences are regulatory compliance certifications. CD19FD911JO3F is ROHS3 compliant and REACH unaffected, while CD19FD911JO3 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance or REACH-unaffected material sourcing, CD19FD911JO3F is appropriate. For applications without these constraints, either part is functionally equivalent.

Q: Can CD19FD911JO3 be replaced with CD19FD911JO3F in existing assemblies?

A: Yes. The parts are mechanically and electrically identical, permitting direct substitution without circuit modification, PCB rework, or performance impact.

Q: Are there inventory differences between these parts?

A: Yes. CD19FD911JO3 has 804 pieces in stock, while CD19FD911JO3F has 1187 pieces in stock. Availability may vary based on current supply conditions.

Q: What is the lead spacing tolerance for these radial capacitors?

A: Lead spacing is 0.343" (8.70 mm) for both parts. This dimension is fixed and identical across both variants.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range -55°C to 125°C, supporting extended thermal environments within this specification.
