Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD502FO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 5000 pF
• Tolerance: ±1%
• Voltage Rating: 500 V
• Dielectric Material: Mica

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.343" (8.70 mm)
• Physical Dimensions: 0.709" L × 0.370" W (18.00 mm × 9.40 mm)
• Maximum Seated Height: 0.591" (15.00 mm)

Environmental Parameters (Must Match Exactly):

• Operating Temperature Range: -55°C to 125°C

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in regulatory compliance status (RoHS, REACH) do not affect electrical or mechanical substitutability but must be evaluated against application requirements.

Engineering Selection Recommendations

Primary Selection (CD19FD502FO3F): The CD19FD502FO3F is the preferred component for applications requiring ROHS3 compliance and REACH unaffected status. This part maintains active production status with adequate inventory availability (838 units). Selection of this part number ensures regulatory alignment for applications subject to RoHS3 and REACH requirements.

Substitute Selection (CD19FD502FO3): The CD19FD502FO3 is a direct electrical and mechanical equivalent suitable for applications where RoHS3 compliance is not mandated and REACH affected status is acceptable. This substitute provides higher current inventory availability (996 units) and maintains identical electrical performance, temperature range, and physical form factor. The substitute is appropriate for legacy systems, non-regulated applications, or designs where regulatory compliance requirements do not apply.

Compliance Considerations: Applications subject to European Union regulations, RoHS directives, or REACH requirements must specify the CD19FD502FO3F. Applications without such regulatory constraints may utilize either part number based on availability and supply chain optimization.

Frequently Asked Questions (FAQ)

Q: Are CD19FD502FO3F and CD19FD502FO3 electrically interchangeable?

A: Yes. Both parts are manufactured by Cornell Dubilier Electronics within the CD19 series and share identical electrical specifications: 5000 pF capacitance, ±1% tolerance, 500 V rating, and mica dielectric. They operate across the same temperature range (-55°C to 125°C) and are suitable for equivalent circuit applications.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. Both parts feature identical mechanical specifications: through-hole radial mounting, 0.343" (8.70 mm) lead spacing, 0.709" L × 0.370" W (18.00 mm × 9.40 mm) physical dimensions, and 0.591" (15.00 mm) maximum seated height. They occupy the same footprint and require no PCB redesign.

Q: What is the difference between CD19FD502FO3F and CD19FD502FO3?

A: The primary differences are regulatory compliance status and current inventory levels. CD19FD502FO3F is ROHS3 compliant and REACH unaffected (838 units in stock). CD19FD502FO3 is RoHS non-compliant and REACH affected (996 units in stock). Electrical and mechanical specifications are identical.

Q: Which part should I specify for a new design?

A: Specify CD19FD502FO3F for designs subject to RoHS3 or REACH regulations. This part number ensures compliance with current European Union directives and is suitable for commercial, industrial, and consumer applications requiring regulatory certification.

Q: Can CD19FD502FO3 be used in applications requiring RoHS3 compliance?

A: No. CD19FD502FO3 is RoHS non-compliant and is not suitable for applications requiring RoHS3 certification. Use CD19FD502FO3F for all RoHS3-regulated applications.

Q: Are both parts currently in production?

A: Yes. Both CD19FD502FO3F and CD19FD502FO3 maintain active production status with Cornell Dubilier Electronics. Both are available as new original components.

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

A: The specified lead spacing is 0.343" (8.70 mm). This dimension is identical for both part numbers and determines PCB hole pattern compatibility.
