Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD19FD432JO3F must maintain electrical and mechanical compatibility based on the following critical parameters:

Electrical Parameters:

• Capacitance: 4300 pF
• Tolerance: ±5%
• Voltage Rating: 500 V
• Dielectric Material: Mica

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.343" (8.70 mm)
• Physical dimensions within specified limits
• Operating Temperature: -55°C ~ 125°C

The substitute part CD19FD432JO3 meets all electrical and mechanical requirements for direct substitution with the primary part number CD19FD432JO3F. Differences in compliance status and product tracking identifiers do not affect electrical or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CD19FD432JO3F and CD19FD432JO3 are active products from Cornell Dubilier Electronics with identical electrical and mechanical specifications. The primary difference lies in regulatory compliance status.

The CD19FD432JO3F is ROHS3 Compliant and REACH Unaffected, making it the preferred choice for applications subject to European Union environmental directives or organizations with strict compliance requirements.

The CD19FD432JO3 is RoHS non-compliant and REACH Affected. This part number is suitable for applications where ROHS3 or REACH compliance is not a requirement.

Selection between these part numbers should be determined by the specific regulatory environment and compliance requirements of the end application.
