Key Parameters

Substitute Part Grouping Explanation

The BFC246731183 qualifies as a direct substitute for BFC246959183 based on the following critical parameters:

• Identical capacitance value: 0.018 µF
• Matching tolerance specification: ±5%
• Equivalent voltage ratings: 400V DC / 220V AC
• Identical dielectric material: Polyester, Metallized
• Matching operating temperature range: -55°C to 105°C
• Compatible mounting configuration: Through Hole Radial
• Identical lead spacing: 0.394" (10.00mm)
• Matching termination type: PC Pins
• Equivalent RoHS compliance: ROHS3 Compliant

The primary distinction between these parts is product status (obsolete versus active) and series designation (MKT469 versus MKT467), with minor physical height variation that does not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

BFC246731183 is the appropriate selection for applications currently specified with BFC246959183. The substitute maintains full electrical equivalence across all critical parameters including capacitance, voltage rating, dielectric composition, and temperature operating range. The active product status of BFC246731183 ensures ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance, satisfying regulatory requirements. The reduced seated height of BFC246731183 (0.630" versus 0.728") presents no compatibility constraint for standard through-hole PCB layouts with standard lead spacing. Packaging format difference (Tape & Reel versus bulk) affects procurement logistics but not component performance or board-level functionality.

Frequently Asked Questions (FAQ)

Q: Can BFC246731183 be used as a direct replacement for BFC246959183 in existing designs?

A: Yes. Both parts share identical electrical specifications (0.018 µF, ±5%, 400V DC, polyester metallized dielectric) and mechanical compatibility (through-hole radial configuration with 0.394" lead spacing). The height difference does not affect standard PCB assembly.

Q: What is the significance of the series designation change from MKT469 to MKT467?

A: Series designation reflects internal Vishay product line organization. The change does not indicate functional differences; both series employ identical dielectric materials, voltage ratings, and capacitance values for this specification.

Q: Does the packaging format change from bulk to Tape & Reel affect component performance?

A: No. Packaging format affects procurement and assembly handling only. Electrical and mechanical properties remain identical regardless of delivery format.

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

A: Both parts maintain ROHS3 compliance. BFC246731183 includes REACH Unaffected status documentation, while BFC246959183 does not specify this parameter. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the practical impact of the 0.098" (2.50mm) height reduction?

A: The reduced height of BFC246731183 provides improved board-level clearance without affecting electrical performance or lead spacing. This represents a design improvement in the active product line.
