Substitute Part Grouping Explanation

Substitution eligibility for the 935C2W3K is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically to establish a valid substitute relationship:

• Capacitance value: 3 µF
• Tolerance specification: ±10%
• DC voltage rating: 200V minimum
• AC voltage rating: 140V minimum
• Dielectric material: Polypropylene (PP), Metallized
• ESR: 13 mOhms
• Operating temperature range: -55°C to 105°C
• Mounting configuration: Through Hole, Axial
• Physical dimensions: 0.654" Dia × 1.500" L
• Termination type: PC Pins

The 935C2W3K-F qualifies as a direct substitute based on complete parameter alignment across all electrical specifications and mechanical form factors. The primary distinction between these parts is product status and compliance certification, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 935C2W3K-F is the direct substitute for the obsolete 935C2W3K. Both components are manufactured by Cornell Dubilier Electronics within the same 935C series and maintain identical electrical and mechanical specifications.

Product Status Consideration: The 935C2W3K carries obsolete status, indicating discontinued production and limited availability. The 935C2W3K-F maintains active product status, ensuring ongoing manufacturing support and supply chain availability.

Compliance Advantage: The 935C2W3K-F achieves ROHS3 compliance, whereas the original 935C2W3K is RoHS non-compliant. Both components maintain REACH Unaffected status and share the same EAR99 export classification and HTSUS code (8532.25.0060).

For applications requiring continued supply, regulatory compliance, or new production designs, the 935C2W3K-F provides functional and dimensional equivalence with enhanced compliance certification and active manufacturing status.
