Key Parameters

Substitute Part Grouping Explanation

The 940C10P22K-F serves as a direct equivalent substitute based on the following critical parameters:

• Capacitance Value: Identical at 0.22 µF
• Tolerance: Matching ±10% specification
• Voltage Rating: Identical DC (1000V) and AC (500V) ratings
• Dielectric Type: Identical polypropylene metallized construction
• ESR: Matching 7 mOhms specification
• Operating Temperature: Identical -55°C to 105°C range
• Package / Case: Identical axial through-hole configuration
• Physical Dimensions: Identical 0.689" Dia x 1.339" L (17.50mm x 34.00mm)
• Termination: Identical PC pins
• Application Requirements: Matching high-pulse and DV/DT capability

The primary distinction between the main part and its substitute is the packaging format and product status, with the substitute available in bulk packaging and classified as active production.

Engineering Selection Recommendations

The 940C10P22K-F is the direct engineering substitute for the obsolete 940C10P22K. The substitute part provides:

• Maintained Functional Equivalence: All electrical parameters (capacitance, voltage rating, ESR, temperature range) and mechanical specifications (dimensions, termination, package type) are identical, ensuring seamless replacement in circuit applications.
• Improved Compliance Status: The 940C10P22K-F achieves ROHS3 compliance, addressing regulatory requirements for new designs and extended product lifecycles.
• Active Production Status: The substitute is actively manufactured, providing supply continuity and long-term availability for continued procurement.
• Series Continuity: Both parts belong to the Cornell Dubilier Electronics 940C film capacitor series, maintaining manufacturer lineage and quality standards.

Selection of the 940C10P22K-F eliminates obsolescence risk while maintaining complete electrical and mechanical compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 940C10P22K-F be used as a direct replacement for the 940C10P22K?

A: Yes. The 940C10P22K-F is a direct engineering substitute with identical electrical parameters (0.22 µF, ±10% tolerance, 1000V DC / 500V AC rating), identical dielectric material (polypropylene metallized), identical ESR (7 mOhms), identical operating temperature range (-55°C to 105°C), and identical physical dimensions and termination. No circuit modification or redesign is required.

Q: What is the difference between these two parts?

A: The primary differences are product status, RoHS compliance, and packaging format. The 940C10P22K is obsolete and RoHS non-compliant, while the 940C10P22K-F is actively manufactured, ROHS3 compliant, and supplied in bulk packaging. All functional and mechanical specifications remain identical.

Q: Are the physical dimensions and pinout identical?

A: Yes. Both parts feature identical axial through-hole package configuration with PC pin termination and identical dimensions of 0.689" Dia x 1.339" L (17.50mm x 34.00mm). Direct PCB replacement is supported without board layout modifications.

Q: Does the RoHS3 compliance of the 940C10P22K-F affect performance?

A: No. RoHS3 compliance reflects manufacturing standards and material composition restrictions but does not impact electrical or thermal performance. The substitute maintains identical performance characteristics in all specified applications.

Q: Is the bulk packaging of the 940C10P22K-F suitable for my application?

A: Bulk packaging affects procurement and handling but does not impact component performance. The 940C10P22K-F is suitable for any application that previously utilized the 940C10P22K, regardless of packaging format.
