Parameter Comparison

Engineering Selection Recommendations

The 940C6P68K-F is a direct electrical and mechanical equivalent to the 940C6P68K. Both parts share identical capacitance, voltage ratings, dielectric material, ESR, operating temperature range, and physical dimensions.

The primary distinction between these parts is product status and regulatory compliance. The 940C6P68K is classified as obsolete, while the 940C6P68K-F maintains active product status. Additionally, the 940C6P68K-F achieves ROHS3 compliance, whereas the 940C6P68K is RoHS non-compliant.

For new designs or applications requiring current component availability and regulatory compliance, the 940C6P68K-F is the appropriate selection. Both parts maintain identical electrical performance characteristics for high pulse and DV/DT applications.

Frequently Asked Questions (FAQ)

Q: Can the 940C6P68K-F replace the 940C6P68K in existing designs?

A: Yes. The 940C6P68K-F is electrically and mechanically equivalent. All electrical parameters, physical dimensions, and termination specifications are identical. Direct substitution is valid without circuit modification.

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

A: The 940C6P68K-F differs from the 940C6P68K in product status and regulatory compliance. The 940C6P68K-F is an active product with ROHS3 compliance, while the 940C6P68K is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between 940C6P68K and 940C6P68K-F?

A: Both parts use identical axial through-hole packaging with PC pin termination. Physical dimensions are 0.709" Dia x 1.339" L (18.00mm x 34.00mm). The primary packaging difference is that 940C6P68K-F is supplied in bulk packaging, while 940C6P68K inventory status is listed as new original stock.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for high pulse and DV/DT applications. The 600V DC and 275V AC ratings, combined with polypropylene metallized dielectric and 6 mOhms ESR, support these application requirements.

Q: Are there any compliance considerations for component selection?

A: The 940C6P68K-F meets ROHS3 compliance requirements, while the 940C6P68K does not. Both parts are REACH unaffected and classified under ECCN EAR99. For applications subject to RoHS regulations, the 940C6P68K-F is the required selection.
