CD19FD561FO3 Equivalent & Substitute Parts

Part Overview

The CD19FD561FO3 is a 560 pF mica capacitor rated for 500 V operation in radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active product status and serves general-purpose applications requiring stable capacitance and high voltage tolerance. The CD19 series mica capacitors are designed for circuits demanding precision capacitance values with minimal drift across temperature ranges from -55°C to 125°C. Identification of equivalent substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or when specific compliance certifications are required for end-application standards.

Substitute Part Grouping Explanation

Substitution of the CD19FD561FO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical capacitance value (560 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), physical dimensions (0.650" L x 0.201" W / 16.50 mm x 5.10 mm), and maximum seated height (0.512" / 13.00 mm). These parameters define the functional and physical interchangeability required for direct component substitution in circuit board layouts and electrical schematics. Variations in any of these parameters disqualify a part from serving as a true equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD561FO3F serves as a parametric equivalent to the CD19FD561FO3, with all electrical and mechanical specifications matching identically. Both components are active products from Cornell Dubilier Electronics within the CD19 series. The primary distinction between these parts lies in regulatory compliance status. The CD19FD561FO3F achieves ROHS3 compliance and REACH unaffected status, whereas the CD19FD561FO3 is classified as RoHS non-compliant and REACH affected. Selection between these equivalents depends on end-application regulatory requirements. Applications subject to RoHS3 or REACH directives require the CD19FD561FO3F variant. Applications without such regulatory constraints may utilize either part. Both components maintain identical functional performance, physical footprint, and electrical characteristics across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CD19FD561FO3F replace CD19FD561FO3 in existing circuit designs?

A: Yes. The CD19FD561FO3F is a parametric equivalent with identical capacitance (560 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 (0.650" L x 0.201" W / 16.50 mm x 5.10 mm). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between CD19FD561FO3 and CD19FD561FO3F?

A: The components are electrically and mechanically identical. The CD19FD561FO3F carries ROHS3 compliance and REACH unaffected certification, while the CD19FD561FO3 is RoHS non-compliant and REACH affected. Selection depends on regulatory requirements for the end application.

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

A: No. Both parts share identical dimensions: 0.650" length x 0.201" width (16.50 mm x 5.10 mm), maximum seated height of 0.512" (13.00 mm), and lead spacing of 0.343" (8.70 mm). PCB layout compatibility is complete.

Q: Which part should be selected for RoHS3-compliant applications?

A: The CD19FD561FO3F is ROHS3 compliant and must be used for applications requiring RoHS3 certification. The CD19FD561FO3 does not meet this requirement.

Q: Are both parts currently available?

A: Both components maintain active product status. Inventory availability: CD19FD561FO3 (735 pcs), CD19FD561FO3F (1033 pcs).
