BFC230363393 Equivalent & Substitute Parts

Part Overview

The BFC230363393 is a 0.039 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, part of the MKT303 series. This radial polyester metallized film capacitor is rated for 630V DC operation with ±10% tolerance and operates across a temperature range of -55°C to 105°C. The component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230363393 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.039 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 630V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Termination: PC Pins (exact match required)
• Operating temperature range: -55°C to 105°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (exact match required)

The BFC237261393 qualifies as a direct substitute based on these parameters. While the AC voltage rating increases from 160V to 250V and physical dimensions vary slightly, these differences do not preclude substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The BFC237261393 is the designated substitute for the obsolete BFC230363393. Both components maintain identical electrical specifications for capacitance, tolerance, DC voltage rating, dielectric material, and operating temperature range. The substitute part is currently in active production status, ensuring availability for replacement and new applications.

Both parts carry ROHS3 compliance certification and MSL rating of 1, meeting regulatory and environmental requirements. The increased AC voltage rating of the substitute (250V versus 160V) provides enhanced performance margin without compromising circuit compatibility. Physical dimension differences, specifically increased width and height, require PCB layout verification to confirm mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can BFC237261393 be used as a direct replacement for BFC230363393?

A: Yes. Both parts share identical capacitance (0.039 µF), tolerance (±10%), DC voltage rating (630V), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), lead spacing (10.00mm), and termination type (PC pins). The substitute is electrically and functionally equivalent.

Q: What are the physical differences between these parts?

A: The BFC237261393 has increased width (6.00mm versus 4.30mm) and height (12.00mm versus 9.00mm). Length remains identical at 12.50mm. Lead spacing is unchanged at 10.00mm. PCB layout must accommodate the larger footprint.

Q: Does the higher AC voltage rating of the substitute affect compatibility?

A: No. The increased AC voltage rating (250V versus 160V) on the substitute represents an enhanced performance specification. Applications designed for the original 160V AC rating will operate within the substitute's capabilities.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC230363393 and BFC237261393 are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: Why is the original part obsolete?

A: The BFC230363393 (MKT303 series) has been discontinued by the manufacturer. The BFC237261393 (MKT372 series) represents the active production equivalent with identical electrical performance.
