Substitute Part Grouping Explanation

Substitution of the CD19FD512JO3F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 5100 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.343" (8.70mm) (exact match required)
• Physical Dimensions: 0.709" L x 0.370" W x 0.591" H max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The substitute part CD19FD512JO3 maintains identical electrical and mechanical specifications, confirming direct substitutability in circuit applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

CD19FD512JO3F is the primary selection for applications requiring ROHS3 compliance and REACH unaffected status. This part is suitable for designs subject to environmental regulations in the European Union and other regions enforcing RoHS and REACH directives.

CD19FD512JO3 serves as a functional equivalent where RoHS3 compliance and REACH unaffected status are not required. This substitute maintains identical electrical performance and physical compatibility. Selection of this part should be based on application requirements and regulatory constraints specific to the end-use market.

Both parts are active products with adequate inventory availability. Selection between them depends solely on compliance certification requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can CD19FD512JO3 be used in place of CD19FD512JO3F?

A: CD19FD512JO3 is electrically and mechanically equivalent to CD19FD512JO3F. Both parts have identical capacitance (5100 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), mounting type (through hole radial), lead spacing (0.343"), and physical dimensions. Substitution is valid from a functional standpoint. However, the substitute part is RoHS non-compliant and REACH affected, whereas the main part is ROHS3 compliant and REACH unaffected. Selection must account for regulatory requirements applicable to the end application.

Q: Are the physical dimensions identical between CD19FD512JO3F and CD19FD512JO3?

A: Yes. Both parts share identical physical specifications: 0.709" length x 0.370" width (18.00mm x 9.40mm), maximum seated height of 0.591" (15.00mm), and lead spacing of 0.343" (8.70mm). PCB layout and mechanical clearance requirements are identical for both parts.

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

A: The primary differences are compliance certifications. CD19FD512JO3F is ROHS3 compliant and REACH unaffected. CD19FD512JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical. The suffix designation in the part number reflects compliance status.

Q: Can I use CD19FD512JO3 in a design that specifies CD19FD512JO3F?

A: Electrical and mechanical substitution is valid. However, compliance requirements must be evaluated. If the design or end-use market requires ROHS3 compliance or REACH unaffected status, CD19FD512JO3 is not suitable. If no such requirements exist, the substitute part is functionally equivalent.

Q: What is the lead spacing for these capacitors?

A: Lead spacing is 0.343 inches (8.70 millimeters) for both parts. This dimension is critical for PCB footprint design and component placement.

Q: Are both parts currently available?

A: Yes. CD19FD512JO3F has 961 units in stock. CD19FD512JO3 has 972 units in stock. Both parts are active products in the Cornell Dubilier Electronics CD19 series.
