Substitute Part Grouping Explanation

Substitution for the CD30FD392JO3 is determined by electrical and mechanical parameter equivalence. The substitute part CD30FD392JO3F maintains identical specifications across all critical electrical parameters: 3900 pF capacitance with ±5% tolerance, 500 V rated voltage, and mica dielectric material. Physical dimensions, lead spacing, and mounting configuration (through-hole radial) are identical. The primary distinction between the original part and its substitute relates to regulatory compliance status: the CD30FD392JO3F variant achieves RoHS3 compliance and REACH Unaffected status, whereas the original part carries RoHS non-compliance and REACH Affected classification. Both parts are classified as Active status and operate within the identical temperature range of -55°C to 125°C.

Parameter Comparison

Engineering Selection Recommendations

The CD30FD392JO3F serves as a direct parametric and mechanical equivalent to the CD30FD392JO3, with both parts delivering identical electrical performance and physical fit within circuit board designs. Selection between these parts depends on regulatory and compliance requirements. Applications requiring RoHS3 compliance or REACH Unaffected designation should specify CD30FD392JO3F. Applications without such constraints or with legacy compliance requirements may utilize either part. Both components carry Active product status, indicating ongoing manufacturer support and continued availability.
