Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BFC236845474 are qualified based on the following critical parameters that determine functional interchangeability:

Mandatory Matching Parameters:

• Capacitance value: 0.47 µF (exact match required)
• Tolerance: ±10% (electrical performance specification)
• Voltage Rating - DC: 250V minimum (safety and reliability requirement)
• Dielectric Material: Polyester, Metallized (electrical characteristics)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: Radial (circuit board layout compatibility)
• Termination: PC Pins (soldering interface)

Allowable Variation Parameters:

• Operating Temperature Range: Minimum -55°C to 105°C acceptable; extended ranges do not disqualify substitution
• Physical dimensions: Lead spacing of 0.886" (22.50mm) is preferred for direct board compatibility; alternative spacing requires PCB layout verification
• Voltage Rating - AC: 160V minimum acceptable; higher ratings provide additional margin

Substitute parts B32521C3474K000 and QXL2E474KTPT meet all mandatory matching parameters and are therefore qualified as direct substitutes for the BFC236845474.

Parameter Comparison

Engineering Selection Recommendations

B32521C3474K000 (EPCOS - TDK Electronics): This substitute offers extended operating temperature capability to 125°C, providing additional thermal margin in high-temperature environments. The compact form factor (13.00mm length, 12.00mm height) enables space-constrained PCB layouts. However, the reduced lead spacing of 0.394" (10.00mm) versus the original 0.886" (22.50mm) requires PCB footprint modification. This part carries AEC-Q200 automotive qualification, suitable for automotive and EMI/RFI suppression applications. RoHS3 compliance and REACH unaffected status maintain regulatory alignment.

QXL2E474KTPT (Nichicon): This substitute maintains identical lead spacing of 0.886" (22.50mm) to the original part, enabling direct PCB compatibility without layout modification. The part is rated for 250V AC operation, providing voltage margin in AC-coupled applications. Operating temperature range extends to 105°C maximum, matching the original specification. Physical dimensions are comparable to the original (25.50mm length, 19.70mm height). RoHS3 compliance and REACH unaffected status maintain regulatory alignment. This part is optimized for high-frequency and switching applications.

Both substitutes maintain the mandatory electrical parameters (0.47 µF capacitance, ±10% tolerance, 250V DC rating, polyester metallized dielectric, through-hole radial package with PC pin termination) and Active product status required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can B32521C3474K000 be used as a direct drop-in replacement for BFC236845474?

A: B32521C3474K000 is electrically equivalent but requires PCB layout verification due to different lead spacing (0.394" versus 0.886"). The reduced spacing necessitates footprint modification. All electrical parameters match the original specification.

Q: What is the primary difference between QXL2E474KTPT and the original BFC236845474?

A: QXL2E474KTPT maintains identical lead spacing and comparable physical dimensions, enabling direct PCB compatibility. The primary difference is the AC voltage rating specification (250V AC versus 160V AC on the original). Both parts meet the 250V DC requirement and operate across compatible temperature ranges.

Q: Are all three parts RoHS3 compliant?

A: Yes. BFC236845474, B32521C3474K000, and QXL2E474KTPT are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should be selected for space-constrained applications?

A: B32521C3474K000 offers the most compact form factor (13.00mm length, 12.00mm height) and is suitable for space-constrained designs. PCB layout modification is required to accommodate the 0.394" lead spacing.

Q: Can these substitutes be used interchangeably in automotive applications?

A: B32521C3474K000 carries AEC-Q200 automotive qualification and is explicitly rated for automotive use. QXL2E474KTPT and BFC236845474 do not carry automotive certifications. Application requirements should determine automotive suitability.

Q: What is the operating temperature consideration when selecting a substitute?

A: BFC236845474 and QXL2E474KTPT operate to 105°C maximum. B32521C3474K000 extends to 125°C, providing additional thermal margin in high-temperature environments. QXL2E474KTPT has a minimum operating temperature of -40°C versus -55°C for the other two parts.
