Key Parameters

Substitute Part Grouping Explanation

Substitution of the 940C12P15K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for capacitance value, voltage ratings (both AC and DC), dielectric material composition, tolerance, ESR characteristics, operating temperature range, physical dimensions, mounting configuration, and termination type. The 940C12P15K-F qualifies as a direct substitute because it shares all these parameters with the main part while offering the advantage of active product status and improved compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 940C12P15K-F is the direct equivalent substitute for the obsolete 940C12P15K. Both parts are manufactured by Cornell Dubilier Electronics within the 940C series and maintain complete electrical and mechanical parameter equivalence. The primary distinction is product status: the 940C12P15K-F holds active product status, ensuring continued availability and manufacturing support. Additionally, the 940C12P15K-F achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. For applications requiring RoHS compliance or long-term component availability, the 940C12P15K-F is the appropriate selection. Both parts share identical REACH status and ECCN/HTSUS classifications. The substitute part maintains the same packaging designation (Bulk) and inventory availability (1085 Pcs New Original In Stock).

Frequently Asked Questions (FAQ)

Q: Can the 940C12P15K-F be used as a direct replacement for the 940C12P15K in existing designs?
