Key Parameters

Substitute Part Grouping Explanation

Substitution of the 940C6P15K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.15 µF (exact match required)
• Tolerance: ±10% (defines acceptable capacitance range)
• Voltage Rating - DC: 600V (minimum voltage withstand requirement)
• Voltage Rating - AC: 275V (AC stress rating)
• Dielectric Material: Polypropylene (PP), Metallized (determines electrical characteristics and temperature stability)
• ESR: 13 mOhms (specifies high-frequency performance and pulse handling capability)
• Operating Temperature Range: -55°C to 105°C (thermal operating envelope)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Axial (physical form factor and lead configuration)
• Size / Dimension: 0.413" Dia x 1.339" L (10.50mm x 34.00mm) (board layout and mechanical fit)
• Termination: PC Pins (solder connection type)
• Applications: High Pulse, DV/DT (intended use case)

The substitute part 940C6P15K-F meets all these parameters identically, with the primary distinction being product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 940C6P15K-F is a direct functional equivalent to the 940C6P15K. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications across all critical parameters including capacitance, voltage ratings, dielectric material, ESR, operating temperature range, and physical dimensions.

The primary distinctions between these parts are:

Product Status: The 940C6P15K is classified as obsolete, while the 940C6P15K-F maintains active product status. Active status indicates ongoing manufacturer support, continued availability, and compliance with current industry standards.

RoHS Compliance: The 940C6P15K is RoHS non-compliant, whereas the 940C6P15K-F is ROHS3 compliant. This distinction is significant for applications subject to RoHS regulations or for integration into systems requiring RoHS-compliant component sourcing.

Packaging Configuration: The 940C6P15K is supplied in standard packaging, while the 940C6P15K-F is supplied in bulk packaging. Packaging selection depends on procurement volume and inventory management requirements.

For new designs, repair operations, or production requiring component continuity, the 940C6P15K-F is the appropriate selection due to its active status and regulatory compliance. Both parts are electrically and mechanically interchangeable within the specified application envelope.

Frequently Asked Questions (FAQ)

Q: Can the 940C6P15K-F be used as a direct replacement for the 940C6P15K in existing designs?

A: Yes. The 940C6P15K-F is electrically and mechanically identical to the 940C6P15K. All critical parameters including capacitance (0.15 µF), voltage ratings (600V DC / 275V AC), dielectric material (polypropylene metallized), ESR (13 mOhms), operating temperature range (-55°C to 105°C), and physical dimensions (0.413" Dia x 1.339" L) are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 940C6P15K is RoHS non-compliant, while the 940C6P15K-F is ROHS3 compliant. RoHS3 compliance indicates the part meets current Restriction of Hazardous Substances regulations. For applications subject to RoHS requirements or for integration into systems requiring RoHS-compliant components, the 940C6P15K-F is the appropriate selection.

Q: Are there any differences in electrical performance between the 940C6P15K and 940C6P15K-F?

A: No. Both parts have identical electrical specifications: 0.15 µF capacitance with ±10% tolerance, 600V DC / 275V AC voltage ratings, 13 mOhms ESR, and -55°C to 105°C operating temperature range. Performance in high pulse and DV/DT applications is equivalent.

Q: What is the difference between standard and bulk packaging?

A: Standard packaging and bulk packaging refer to the quantity and presentation format of components during shipment. Bulk packaging typically accommodates larger order quantities. Selection depends on procurement volume and inventory management requirements. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Why is the 940C6P15K classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The 940C6P15K-F represents the current active equivalent, ensuring ongoing availability, manufacturer support, and compliance with contemporary standards.

Q: Are both parts suitable for high pulse and DV/DT applications?

A: Yes. Both the 940C6P15K and 940C6P15K-F are specified for high pulse and DV/DT applications. The polypropylene metallized dielectric, 13 mOhms ESR, and 600V DC rating support these demanding electrical conditions.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts are through-hole axial components with identical physical dimensions (0.413" Dia x 1.339" L / 10.50mm x 34.00mm) and PC pin termination. They are mechanically and electrically interchangeable in PCB assembly applications.
