Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC236521473 is based on electrical and mechanical parameter equivalence. The following criteria determine functional interchangeability:

Critical Electrical Parameters:

• Capacitance value: 0.047 µF
• Tolerance: ±10%
• Voltage rating: 100V DC minimum
• Dielectric type: Polyester, Metallized

Critical Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.197" (5.00mm)
• Physical dimensions: 0.394" L x 0.157" W (10.00mm x 4.00mm)
• Height seated: 0.532" (13.50mm) maximum

Compliance Requirements:

• RoHS3 compliance maintained
• Operating temperature range: -55°C to 105°C

The substitute part BFC236621473 meets all these criteria, differing only in series designation (MKT366 vs. MKT365) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The BFC236621473 is the direct equivalent substitute for the obsolete BFC236521473. Both parts are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: BFC236621473 is currently in active production, whereas BFC236521473 is obsolete. This makes BFC236621473 the appropriate selection for new designs, component replenishment, and system maintenance where the original part is no longer available.

Both parts maintain ROHS3 compliance and are suitable for general-purpose applications within the specified operating temperature range of -55°C to 105°C. The series change from MKT365 to MKT366 reflects manufacturing evolution within the same product family, with no impact on functional performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can BFC236621473 be used as a direct replacement for BFC236521473?

A: Yes. All electrical parameters (capacitance, tolerance, voltage rating, dielectric type) and mechanical parameters (dimensions, lead spacing, mounting configuration) are identical. The parts are pin-compatible and functionally equivalent.

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

A: Both series are polyester metallized film capacitors manufactured by Vishay. The MKT366 represents the current production series, while MKT365 is obsolete. No functional differences exist between the series for this specific part value and rating.

Q: Are there any packaging differences between these parts?

A: The main part (BFC236521473) uses standard packaging, while the substitute (BFC236621473) is supplied in Tape & Reel (TR) format. Both maintain identical physical dimensions and lead spacing, ensuring mechanical compatibility in through-hole applications.

Q: Is RoHS compliance maintained with the substitute part?

A: Yes. Both BFC236521473 and BFC236621473 are ROHS3 compliant.

Q: Can this capacitor be used in high-temperature applications?

A: The operating temperature range is -55°C to 105°C. Applications requiring operation outside this range require alternative component selection.
