Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC233922334 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.33 µF
• Tolerance: ±20%
• Voltage ratings: 630V DC / 310V AC minimum
• Dielectric material: Polypropylene (PP), Metallized
• Mounting configuration: Through Hole Radial
• Physical dimensions: 17.50mm x 8.50mm with 15.00mm lead spacing
• Termination type: PC Pins

Two substitute parts meet these criteria: BFC233820334 (MKP338 series) and BFC233920334 (MKP339 series). Both maintain identical electrical specifications and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. BFC233820334 is classified as a manufacturer-recommended substitute and carries AEC-Q200 automotive qualification on the main part and X2 rating on the substitute. BFC233920334 is a parametric equivalent within the same MKP339 series as the original part, also carrying AEC-Q200 and X2 ratings.

Selection between these parts should be based on supply chain availability and application-specific requirements. BFC233920334 offers the highest inventory level at 6850 units. BFC233820334 provides an alternative from the MKP338 series with 1900 units available. All three parts satisfy identical electrical and mechanical specifications for direct substitution in through-hole radial capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can BFC233820334 and BFC233920334 be used interchangeably with BFC233922334?

A: Yes. Both substitute parts maintain identical capacitance (0.33 µF), tolerance (±20%), voltage ratings (630V DC / 310V AC), dielectric material (polypropylene metallized), operating temperature range (-55°C to 110°C), and physical dimensions (17.50mm x 8.50mm with 15.00mm lead spacing). All three parts use PC pin termination and through-hole radial mounting.

Q: What is the difference between the MKP338 and MKP339 series?

A: Both series are polypropylene metallized film capacitors from Vishay with identical electrical and mechanical specifications for this 0.33 µF 630V application. Series designation reflects internal design evolution within the manufacturer's product line but does not affect functional compatibility.

Q: Are there any compliance or certification differences?

A: All three parts are ROHS3 compliant and REACH unaffected. BFC233922334 and BFC233920334 carry AEC-Q200 automotive qualification. BFC233820334 carries X2 rating. These certifications do not prevent substitution; they indicate the qualification level for specific application environments.

Q: Which part should be selected for new designs?

A: Selection should prioritize availability and supply chain lead times. BFC233920334 offers the highest inventory (6850 units). All three parts are active products suitable for new designs requiring 0.33 µF 630V polypropylene film capacitors in through-hole radial configuration.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions of 17.50mm length x 8.50mm width with 15.00mm lead spacing and maximum seated height of 15.00mm. PCB layout and mechanical clearance requirements are identical.
