Substitute Part Grouping Explanation

Substitute parts for the MKS4F032203F00KSC9 are identified based on strict electrical and mechanical parameter matching. The substitution logic requires equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±10% (identical tolerance band)
• DC voltage rating: 250V (minimum requirement)
• AC voltage rating: 160V (minimum requirement)
• Dielectric material: Polyester (PET), metallized construction
• Operating temperature range: -55°C to 125°C (full range coverage)

Mechanical Parameters:

• Mounting type: Through hole, radial configuration
• Lead spacing: 0.394" (10.00mm) center-to-center
• Physical dimensions: 0.512" L x 0.197" W (13.00mm x 5.00mm)
• Height seated maximum: 0.433" (11.00mm)
• Termination: PC pins for wave or hand soldering

Compliance Parameters:

• AEC-Q200 automotive qualification (required for automotive applications)
• Active product status (current manufacturing availability)

The B32521C3224K000 from EPCOS - TDK Electronics satisfies all specified parameters and qualifies as a parametric equivalent.

Engineering Selection Recommendations

Primary Selection: MKS4F032203F00KSC9 (WIMA)

The MKS4F032203F00KSC9 remains the primary component choice when available. Current inventory of 1011 units supports immediate procurement. This part carries active product status and full AEC-Q200 automotive qualification.

Substitute Selection: B32521C3224K000 (EPCOS - TDK Electronics)

The B32521C3224K000 qualifies as a direct parametric equivalent when the primary part is unavailable. This substitute maintains identical electrical specifications (0.22 µF, ±10%, 250V DC, 160V AC) and mechanical compatibility (10.00mm lead spacing, identical physical dimensions, through-hole radial mounting). Both parts satisfy AEC-Q200 automotive requirements and operate across the full -55°C to 125°C temperature range. The substitute carries active product status with 4874 units in inventory, providing supply continuity. The stacked metallized construction of the B32521C3224K000 represents a manufacturing variation within the polyester film capacitor category that does not affect electrical performance or circuit compatibility.

Both parts are ROHS3 compliant and carry EAR99 export classification. Selection between these equivalents depends solely on availability and procurement lead time.

Frequently Asked Questions (FAQ)

Q: Can the B32521C3224K000 be used as a direct replacement for the MKS4F032203F00KSC9 on existing PCBs?

A: Yes. Both parts share identical lead spacing (10.00mm), physical dimensions (13.00mm x 5.00mm), and maximum seated height (11.00mm). The radial through-hole mounting configuration is identical. No PCB layout modifications are required.

Q: Are there electrical performance differences between these two capacitors?

A: No. Both parts specify 0.22 µF capacitance with ±10% tolerance, 250V DC rating, 160V AC rating, and -55°C to 125°C operating temperature range. The dielectric material is polyester (PET) with metallized construction in both cases. Electrical performance is equivalent.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the MKS4F032203F00KSC9 and B32521C3224K000 carry AEC-Q200 automotive qualification. Either part is acceptable for automotive applications requiring this standard.

Q: What is the difference between standard metallized and stacked metallized construction?

A: The B32521C3224K000 uses stacked metallized construction, which is a manufacturing technique within polyester film capacitor design. This variation does not affect the electrical specifications, voltage ratings, capacitance value, or circuit compatibility. Both construction methods deliver equivalent performance for this application.

Q: Can I mix these two part numbers in the same production run?

A: Yes. Both parts are parametrically equivalent and carry identical electrical and mechanical specifications. Mixing these parts in the same production run does not create compatibility or performance issues.

Q: What is the lead time difference between these two parts?

A: The MKS4F032203F00KSC9 has 1011 units in stock. The B32521C3224K000 has 4874 units in stock. Actual lead times depend on your supplier's inventory management and order fulfillment processes.

Q: Are there any compliance or certification differences?

A: Both parts are AEC-Q200 qualified, ROHS3 compliant, and carry EAR99 export classification. The B32521C3224K000 includes REACH Unaffected status. No compliance barriers exist for substitution.
