BFC246926224 Equivalent & Substitute Parts
Part Overview
The BFC246926224 is a 0.22 µF film capacitor rated for 100V DC operation, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the MKT469 series. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The radial through-hole configuration and polyester metallized dielectric make this capacitor suitable for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges.

Substitute Part Grouping Explanation
Substitution of the BFC246926224 is determined by strict equivalence across the following critical parameters:
Capacitance value must match exactly at 0.22 µF with tolerance maintained at ±5%. Voltage ratings must meet or exceed both the 100V DC and 63V AC specifications. The dielectric material must remain polyester metallized to preserve circuit performance characteristics. Mounting configuration must be through-hole radial with identical lead spacing of 0.394" (10.00mm) to ensure PCB compatibility without layout modification. Operating temperature range must span the full -55°C to 105°C specification. RoHS3 compliance is required for regulatory alignment.
The BFC246705224 qualifies as a direct substitute based on these parameters, despite belonging to the MKT467 series rather than the original MKT469 series.

Engineering Selection Recommendations
The BFC246705224 is the qualified substitute for the obsolete BFC246926224. Both components are manufactured by Vishay and maintain identical electrical specifications across capacitance, voltage rating, tolerance, and dielectric composition. Both achieve ROHS3 compliance, satisfying regulatory requirements for current production environments.
The primary physical difference is the seated height: the substitute measures 0.575" (14.60mm) compared to the original 0.453" (11.50mm). This 0.122" (3.10mm) increase in height must be evaluated against PCB clearance constraints and enclosure dimensions. If vertical space is constrained, this difference may require design review. Lead spacing and footprint remain identical, permitting direct PCB mounting without layout modification.
The substitute's active product status ensures ongoing availability and supply chain continuity, addressing the obsolescence limitation of the original part.
Frequently Asked Questions (FAQ)
Q: Can BFC246705224 be used as a direct replacement for BFC246926224 on existing PCBs?
A: Yes, from an electrical and footprint perspective. The lead spacing, termination type, and mounting configuration are identical. However, the increased seated height (0.575" versus 0.453") must be confirmed against available vertical clearance in the assembly.
Q: What is the significance of the series change from MKT469 to MKT467?
A: Both series are Vishay polyester film capacitor lines with identical electrical performance for this capacitance and voltage rating. The series designation reflects internal product line organization and does not affect functional compatibility.
Q: Are there any compliance differences between the original and substitute?
A: Both components are ROHS3 compliant. The substitute includes additional REACH Unaffected certification documentation. No compliance barriers exist for substitution.
Q: Why is the substitute part taller?
A: The MKT467 series uses a different physical construction that results in increased height while maintaining the same capacitance, voltage rating, and lead spacing. This is a design variation within Vishay's product portfolio.
Q: Is the ±5% tolerance maintained in the substitute?
A: Yes. Both the original BFC246926224 and substitute BFC246705224 maintain ±5% capacitance tolerance.
Q: Can the substitute handle the full -55°C to 105°C operating temperature range?
A: Yes. The BFC246705224 is rated for the identical -55°C to 105°C operating temperature range as the original component.
