• Voltage ratings: 250V DC and 160V AC (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.394" / 10.00mm (exact match required)
• Termination style: PC Pins (exact match required)

The substitute part BFC236845473 meets all these criteria, confirming full parametric equivalence within the MKT368 series from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both BFC236843473 and BFC236845473 are active production components manufactured by Vishay Beyschlag/Draloric/BC Components with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture sensitivity constraints. Selection between these parts should be based on inventory availability and supply chain logistics, as they are functionally and physically interchangeable in all applications requiring a 0.047 µF, 250V DC rated film capacitor with radial through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can BFC236845473 be used as a direct replacement for BFC236843473?

A: Yes. Both parts are parametrically identical across all electrical specifications (capacitance, voltage ratings, tolerance, dielectric material, operating temperature range) and mechanical specifications (package type, lead spacing, termination style, physical dimensions). They belong to the same MKT368 series and are manufactured by the same company.

Q: Are there any differences in PCB board layout or mounting considerations?

A: No. Both parts share identical lead spacing (0.394" / 10.00mm), physical dimensions (0.492" L x 4.50mm W), and maximum seated height (0.532" / 13.50mm). PCB footprints and mounting procedures are identical.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both BFC236843473 and BFC236845473 are ROHS3 compliant and carry MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions without moisture sensitivity concerns.

Q: What is the primary reason to use a substitute part?

A: Substitute parts are selected when the primary part number experiences supply constraints, extended lead times, or inventory depletion. BFC236845473 offers higher current inventory availability (2625 units versus 937 units), making it a viable alternative for immediate procurement needs.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate identically within the specified capacitance range (0.047 µF ±10%), voltage ratings (250V DC / 160V AC), and temperature operating range (-55°C to 105°C). They utilize the same polyester metallized dielectric technology and long-life design features.
