Key Parameters

Substitute Part Grouping Explanation

Substitution of the 935C2W1K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 200V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 140V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• ESR: 20 mOhms (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.449" Dia x 1.248" L (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical compatibility within the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The 935C2W1K-F is a direct substitute for the obsolete 935C2W1K. Both components are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance. The 935C2W1K-F carries an active product status, ensuring continued availability and supply chain support. Additionally, the 935C2W1K-F is ROHS3 compliant, whereas the original 935C2W1K is RoHS non-compliant. This compliance difference is significant for applications subject to RoHS regulations or for equipment requiring compliance documentation.

Both components maintain identical REACH and ECCN classifications, confirming equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the 935C2W1K-F replace the 935C2W1K in existing circuit designs?

A: Yes. The 935C2W1K-F is electrically and mechanically equivalent to the 935C2W1K across all specified parameters, including capacitance, voltage rating, dielectric material, ESR, operating temperature range, and physical dimensions. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference between these parts?

A: The 935C2W1K is classified as obsolete, indicating discontinued manufacturing and limited availability. The 935C2W1K-F maintains active product status, ensuring ongoing production, supply chain availability, and manufacturer support. For new designs or long-term production requirements, the active 935C2W1K-F is the appropriate selection.

Q: Does the RoHS3 compliance of the 935C2W1K-F affect compatibility?

A: RoHS3 compliance of the 935C2W1K-F indicates adherence to current environmental and hazardous substance restrictions. This compliance status does not affect electrical or mechanical compatibility. For applications or markets requiring RoHS compliance documentation, the 935C2W1K-F is the required selection.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 935C2W1K and 935C2W1K-F share identical axial package dimensions of 0.449" diameter by 1.248" length (11.40mm x 31.70mm). PCB layout and mechanical mounting considerations remain unchanged.

Q: What is the packaging difference between these parts?

A: The 935C2W1K-F is supplied in bulk packaging, whereas the original 935C2W1K packaging specification is not detailed in the provided data. For procurement purposes, confirm packaging requirements with the supplier, as bulk packaging may affect order quantities and handling procedures.

Q: Are there any applications where the 935C2W1K cannot be substituted with the 935C2W1K-F?

A: No. The 935C2W1K-F is a complete functional equivalent across all electrical, mechanical, and environmental parameters. Substitution is valid for all applications originally specified for the 935C2W1K, including high-frequency and switching circuit applications.
