BFC246958683 Equivalent & Substitute Parts

Part Overview

The BFC246958683 is a 0.068 µF film capacitor rated for 400V 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 system support and component procurement. The radial through-hole configuration with polyester metallized dielectric serves general-purpose applications requiring stable capacitance across the specified temperature range of -55°C to 105°C.

Substitute Part Grouping Explanation

Substitution of the BFC246958683 is determined by strict equivalence across the following critical parameters:

Capacitance value: 0.068 µF (exact match required)
Tolerance: ±10% (matching tolerance band)
Voltage rating: 400V DC minimum / 220V AC minimum
Dielectric type: Polyester, Metallized (material consistency)
Mounting configuration: Through-hole radial with 10.00mm lead spacing
Termination style: PC Pins
Operating temperature range: -55°C to 105°C minimum
RoHS compliance: ROHS3 Compliant

The BFC246730683 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the transition from obsolete (MKT469 series) to active product status (MKT467 series), with a minor reduction in seated height from 18.50mm to 16.00mm, which does not affect functional compatibility in standard through-hole applications.

Engineering Selection Recommendations

The BFC246730683 is the direct substitute for the obsolete BFC246958683. Both components maintain identical electrical specifications and mechanical compatibility for through-hole PCB applications. The transition from MKT469 to MKT467 series represents a product line consolidation by the manufacturer, with the newer series offering active product status and improved supply chain availability.

The reduction in seated height (18.50mm to 16.00mm) presents no functional constraint for standard applications and may provide marginal benefits in compact board layouts. Both components satisfy ROHS3 compliance requirements and operate across the full -55°C to 105°C temperature range.

Component selection should prioritize the BFC246730683 due to its active product status, ensuring long-term availability and consistent manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can BFC246730683 be used as a direct replacement for BFC246958683 in existing designs?

A: Yes. The BFC246730683 matches all critical electrical parameters (capacitance, voltage rating, tolerance, dielectric type) and mechanical specifications (lead spacing, termination style, mounting configuration) required for direct substitution in through-hole applications.

Q: What is the significance of the height difference between the two parts?

A: The BFC246730683 has a maximum seated height of 16.00mm compared to 18.50mm for the BFC246958683. This 2.50mm reduction does not affect electrical performance and may accommodate tighter vertical clearance constraints on PCBs. Standard through-hole spacing remains unchanged at 10.00mm.

Q: Why is the BFC246958683 classified as obsolete?

A: The BFC246958683 belongs to the MKT469 series, which has been superseded by the MKT467 series. The manufacturer has consolidated product lines, with the BFC246730683 representing the active equivalent offering identical performance with improved supply availability.

Q: Are there any compliance differences between the two parts?

A: Both components are ROHS3 compliant. The BFC246730683 lists Moisture Sensitivity Level as Not Applicable, while the BFC246958683 specifies MSL 1 (Unlimited). This difference does not affect substitution suitability for standard storage and handling conditions.

Q: What packaging options are available for the substitute part?

A: The BFC246730683 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original BFC246958683 packaging specification was not provided in the technical data.
