Substitute Part Grouping Explanation

Substitution of the BFC236546473 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±5% (matching tolerance band)
• Voltage ratings: 250V DC and 160V AC (minimum required ratings)
• Dielectric type: Polyester, Metallized (material specification)
• Mounting configuration: Through Hole, Radial package with 5.00mm lead spacing
• Physical dimensions: 10.00mm L × 4.00mm W with 13.50mm maximum seated height
• Termination style: PC Pins
• Compliance: ROHS3 Compliant

The BFC236646473 qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and compliance certifications, with the distinction that it represents an active product in the MKT366 series.

Parameter Comparison

Engineering Selection Recommendations

The BFC236646473 is the direct equivalent for the obsolete BFC236546473. Both components maintain identical electrical performance specifications, mechanical form factors, and regulatory compliance certifications. The transition from MKT365 to MKT366 series represents a product line evolution within the same manufacturer portfolio, with no functional differences affecting circuit performance or board-level integration.

Selection of the BFC236646473 is appropriate for all applications previously served by the BFC236546473, including general-purpose film capacitor requirements in 250V DC circuits. The active product status of the BFC236646473 ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can BFC236646473 be used as a direct replacement for BFC236546473 in existing designs?

A: Yes. Both components share identical electrical ratings (0.047 µF, 250V DC, 160V AC), tolerance specifications (±5%), dielectric material (polyester metallized), and mechanical dimensions (10.00mm × 4.00mm with 5.00mm lead spacing). No circuit modifications or board layout changes are required.

Q: What is the difference between the MKT365 and MKT366 series?

A: The MKT365 series (BFC236546473) is obsolete. The MKT366 series (BFC236646473) is the active product line continuation from Vishay. Both series maintain equivalent electrical and mechanical specifications for this capacitance value and voltage rating.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant. No compliance or certification differences exist that would affect component selection or application suitability.

Q: Does packaging format affect substitution compatibility?

A: The BFC236646473 is supplied in Tape & Box (TB) packaging. Packaging format does not affect electrical performance or mechanical compatibility. Component functionality remains identical regardless of packaging configuration.

Q: What is the lead spacing specification, and why is it important?

A: Both components feature 5.00mm lead spacing, which determines PCB pad layout and through-hole positioning. Identical lead spacing ensures direct board-level compatibility without layout modifications.
