BFC246952182 Equivalent & Substitute Parts

Part Overview

The BFC246952182 is a 1800 pF 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 substitute parts essential for ongoing design support and production continuity. The polyester metallized dielectric construction provides stable performance across the operating temperature range of -55°C to 105°C in general-purpose applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC246952182 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1800 pF
• Tolerance: ±5%
• Voltage rating: 400V DC / 220V AC minimum
• Dielectric type: Polyester, Metallized
• Mounting configuration: Through Hole Radial
• Lead spacing: 0.394" (10.00mm)
• Operating temperature range: -55°C to 105°C minimum
• Termination style: PC Pins

The BFC246756182 meets all these criteria and qualifies as a direct substitute. Physical dimensions may vary within the radial package envelope, provided lead spacing and termination remain compatible with the original PCB layout.

Parameter Comparison

Engineering Selection Recommendations

The BFC246756182 is the appropriate substitute for the obsolete BFC246952182. Both components are manufactured by Vishay and maintain identical electrical specifications, dielectric composition, and mechanical compatibility. The substitute part is currently in active production status, ensuring supply chain availability.

The primary dimensional difference is seated height: the substitute measures 0.571" (14.50mm) compared to the original 0.453" (11.50mm). This 3mm increase must be evaluated against available PCB clearance in the target application. Lead spacing and footprint remain unchanged at 0.394" (10.00mm), confirming PCB layout compatibility.

Both parts maintain ROHS3 compliance and identical electrical performance across the specified operating temperature and voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can BFC246756182 be used as a direct replacement for BFC246952182?

A: Yes. Both components share identical capacitance (1800 pF), tolerance (±5%), voltage ratings (400V DC / 220V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), lead spacing (10.00mm), and termination style (PC Pins). The substitute is electrically and mechanically compatible.

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

A: The BFC246756182 has a maximum seated height of 14.50mm compared to 11.50mm for the BFC246952182. This 3mm difference must be verified against available vertical clearance on the PCB and within the enclosure. If clearance is limited, alternative solutions may be required.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. No compliance or certification differences exist between the main part and substitute.

Q: Why is the original part obsolete?

A: The BFC246952182 (MKT469 series) is classified as obsolete by the manufacturer. The BFC246756182 (MKT467 series) represents the active production equivalent from the same manufacturer.

Q: Can these parts be used interchangeably in all applications?

A: Electrical interchangeability is confirmed. Physical interchangeability depends on PCB layout constraints, particularly the 3mm height difference. PCB clearance verification is required before implementation.
