MKP4J021002B00KSSD Film Capacitor Equivalent & Substitute Parts

Part Overview

The MKP4J021002B00KSSD is a 10000 pF (0.01 µF) film capacitor manufactured by WIMA, designed for high-frequency and switching applications. This polypropylene metallized radial capacitor operates at 630V DC with a ±10% tolerance and is rated for temperatures from -55°C to 105°C. The component is currently in active production status with 897 pieces available in stock. Alternative equivalent parts may be required due to supply constraints, lead time considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MKP4J021002B00KSSD is determined by strict adherence to the following electrical and mechanical parameters:

Critical Electrical Parameters:

• Capacitance value must be 10000 pF (0.01 µF) with ±10% tolerance
• Voltage rating must be rated for minimum 630V DC operation
• Dielectric material must be film-based (polypropylene or polyester metallized)

Critical Mechanical Parameters:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Termination must be PC Pins
• Lead spacing must accommodate 0.295" (7.50mm) or compatible spacing

Environmental Parameters:

• Operating temperature range must support -55°C to 105°C or equivalent
• Moisture sensitivity level must be compatible with application requirements

Substitute parts must satisfy all critical parameters simultaneously. Deviations in any critical parameter disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Based on the parameter comparison, the ECQ-E6104KF (Panasonic) is not a direct equivalent substitute for the MKP4J021002B00KSSD (WIMA). The following factors prevent substitution:

1. Capacitance Mismatch: The ECQ-E6104KF has a capacitance of 0.1 µF, which is 10 times higher than the required 10000 pF. This fundamental difference makes it unsuitable for direct replacement in circuits designed for 0.01 µF operation.

2. Lead Spacing Incompatibility: The MKP4J021002B00KSSD has 7.50mm lead spacing, while the ECQ-E6104KF has 15.00mm lead spacing. This difference prevents direct PCB mounting without circuit board redesign.

3. Physical Footprint Difference: The Panasonic part is significantly larger (18.50mm x 6.30mm vs. 10.00mm x 3.00mm), creating space constraint issues in compact designs.

4. Dielectric Material Difference: Polypropylene and polyester film capacitors have different electrical characteristics. Polypropylene offers superior frequency response and lower losses for high-frequency applications.

5. Temperature Range: The WIMA part supports -55°C operation, while the Panasonic part is limited to -40°C minimum.

For applications requiring the MKP4J021002B00KSSD, equivalent parts must match the 10000 pF capacitance value, 630V DC rating, 7.50mm lead spacing, and polypropylene dielectric material. The ECQ-E6104KF should only be considered if circuit requirements allow for 0.1 µF capacitance and PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6104KF replace the MKP4J021002B00KSSD in my circuit?

A: No. The ECQ-E6104KF has a capacitance of 0.1 µF, which is 10 times higher than the required 10000 pF. Direct substitution will cause circuit malfunction. Additionally, the lead spacing (15.00mm vs. 7.50mm) and physical dimensions are incompatible with the original PCB layout.

Q: What are the critical parameters for finding a true equivalent?

A: A true equivalent must have: 10000 pF capacitance with ±10% tolerance, 630V DC minimum rating, polypropylene metallized dielectric, through-hole radial package, PC pin termination, and 7.50mm lead spacing. All parameters must be matched simultaneously.

Q: Why is lead spacing important for substitution?

A: Lead spacing determines the distance between mounting holes on the printed circuit board. A mismatch (7.50mm vs. 15.00mm) means the component cannot be inserted into the existing PCB without physical modification or rewiring, making it unsuitable for direct substitution.

Q: Does the dielectric material matter for substitution?

A: Yes. Polypropylene and polyester film capacitors have different electrical properties. Polypropylene offers lower dissipation factor and better performance in high-frequency and switching applications. Substituting with polyester may degrade circuit performance.

Q: What is the significance of the operating temperature range difference?

A: The MKP4J021002B00KSSD operates from -55°C to 105°C, while the ECQ-E6104KF operates from -40°C to 105°C. If your application requires operation below -40°C, the Panasonic part cannot be used.

Q: Are there compliance differences between these parts?

A: The ECQ-E6104KF is ROHS3 compliant and REACH unaffected. The WIMA part's compliance status is not specified in the provided data. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What should I do if the MKP4J021002B00KSSD is unavailable?

A: Contact the component supplier for alternative 10000 pF, 630V DC, polypropylene metallized radial capacitors with 7.50mm lead spacing from other manufacturers. Do not substitute with parts having different capacitance values or lead spacing without circuit redesign and validation.
