CD19FD302FO3F Equivalent & Substitute Parts

Part Overview

The CD19FD302FO3F is a 3000 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD19 series. This through-hole radial component operates at 500 V rated voltage with ±1% tolerance and is designed for general-purpose applications across an operating temperature range of -55°C to 125°C. The part is currently active in production status. Substitute parts are identified when inventory constraints, compliance requirements, or procurement lead times necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD302FO3F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 3000 pF (exact match required)
• Tolerance: ±1% (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: 0.681" L x 0.280" W, Height 0.551" max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The identified substitute part CD19FD302FO3 maintains complete electrical and mechanical compatibility with the primary part number across all specified parameters. Differences in regulatory compliance status (RoHS and REACH) do not affect functional substitution but must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CD19FD302FO3F is the preferred component for new designs and applications requiring ROHS3 compliance and REACH unaffected status. This part maintains active production status with robust inventory availability (889 pieces).

Substitute Selection: CD19FD302FO3 provides complete electrical and mechanical equivalence and is suitable for applications where RoHS3 compliance is not mandated and REACH affected status is acceptable. This part is also in active production with adequate inventory (672 pieces).

Compliance Considerations: Applications subject to RoHS3 regulations or REACH compliance requirements must use CD19FD302FO3F. Applications without these regulatory constraints may utilize CD19FD302FO3 as a direct functional substitute. Both parts are manufactured by the same supplier (Cornell Dubilier Electronics) within the same CD19 series.

Frequently Asked Questions (FAQ)

Q: Can CD19FD302FO3 be used in place of CD19FD302FO3F?

A: CD19FD302FO3 is electrically and mechanically equivalent to CD19FD302FO3F across all specified parameters including capacitance, voltage rating, tolerance, dielectric material, mounting type, and physical dimensions. Substitution is valid from a functional standpoint. However, regulatory compliance differences must be evaluated: CD19FD302FO3F is ROHS3 compliant and REACH unaffected, while CD19FD302FO3 is RoHS non-compliant and REACH affected.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.681" length x 0.280" width (17.30mm x 7.10mm), maximum seated height of 0.551" (14.00mm), and lead spacing of 0.343" (8.70mm). PCB layout and mechanical fit are interchangeable.

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

A: The primary differences are regulatory compliance status and inventory levels. CD19FD302FO3F is ROHS3 compliant with REACH unaffected status, while CD19FD302FO3 is RoHS non-compliant with REACH affected status. Electrical specifications, physical dimensions, and performance characteristics are identical.

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

A: Specify CD19FD302FO3F for new designs unless specific regulatory exemptions apply. This part maintains current compliance certifications and active production status.

Q: Are both parts currently in production?

A: Yes. Both CD19FD302FO3F and CD19FD302FO3 maintain active product status with Cornell Dubilier Electronics.
