Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC233922473 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF
• Tolerance: ±20%
• Voltage ratings: 630V DC / 310V AC
• Dielectric type: Polypropylene (PP), Metallized
• Operating temperature range: -55°C ~ 110°C
• Mounting configuration: Through Hole Radial
• Lead spacing: 0.295" (7.50mm)
• Series classification: MKP339

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in electrical or mechanical specifications are permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

Both BFC233922473 and BFC233920473 are active products with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain considerations. Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification, ensuring equivalent performance in automotive and EMI/RFI suppression applications. The BFC233920473 offers higher inventory availability (11,099 pcs vs. 1,107 pcs), making it the preferred choice for high-volume procurement when supply continuity is a consideration.

Frequently Asked Questions (FAQ)

Q: Can BFC233920473 be used as a direct replacement for BFC233922473?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.047 µF), voltage ratings (630V DC / 310V AC), dielectric material (Polypropylene metallized), operating temperature range (-55°C ~ 110°C), and mechanical dimensions. They are interchangeable in all applications.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both parts carry AEC-Q200 certification and X2 ratings, meeting identical automotive reliability standards.

Q: What determines substitution eligibility for this capacitor?

A: Substitution requires exact matching of capacitance value, tolerance, voltage ratings, dielectric type, operating temperature range, mounting configuration, and lead spacing. Any deviation in these parameters disqualifies a part from substitution classification.

Q: Does lead spacing affect PCB compatibility?

A: Yes. Both parts maintain 0.295" (7.50mm) lead spacing and identical radial package dimensions (0.394" L x 0.197" W, 10.50mm seated height). PCB layouts designed for either part are fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC233922473 and BFC233920473 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
