Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230341394 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.39 µF (exact match required)
• Capacitance tolerance: ±10% (matching tolerance band)
• Voltage rating - DC: 250V (minimum requirement; higher ratings acceptable)
• Voltage rating - AC: 63V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polyester, Metallized (material class equivalence)
• Operating temperature range: -55°C to 105°C (minimum requirement; extended ranges acceptable)
• Mounting type: Through Hole (form factor requirement)
• Package / Case: Radial (form factor requirement)
• Lead spacing: 0.394" (10.00mm) (PCB layout compatibility requirement)
• Termination: PC Pins (connection method requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The substitute part BFC2373EE394MD meets all these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The BFC2373EE394MD is the manufacturer-recommended substitute for the obsolete BFC230341394. Both components are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain identical electrical specifications across capacitance, voltage ratings, dielectric material, and operating temperature range. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring equivalent regulatory and environmental performance.

The primary distinction is product status: the BFC230341394 is obsolete, while the BFC2373EE394MD is active with confirmed inventory availability. The substitute exhibits minor dimensional variations in width (5.00mm versus 4.90mm) and seated height (11.00mm versus 9.60mm), while maintaining identical lead spacing of 10.00mm for PCB compatibility. These dimensional differences do not affect electrical function and remain within standard radial capacitor form factor tolerances.

Frequently Asked Questions (FAQ)

Q: Can BFC2373EE394MD be used as a direct replacement for BFC230341394?

A: Yes. Both components share identical electrical specifications: 0.39 µF capacitance, ±10% tolerance, 250V DC / 63V AC ratings, polyester metallized dielectric, -55°C to 105°C operating range, and 10.00mm lead spacing. The substitute is the manufacturer-recommended equivalent.

Q: What are the dimensional differences between these parts?

A: The BFC2373EE394MD is slightly wider (5.00mm versus 4.90mm) and taller when seated (11.00mm versus 9.60mm). Lead spacing remains identical at 10.00mm. These variations are within standard radial capacitor tolerances and do not affect PCB layout compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC230341394 and BFC2373EE394MD are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current regulatory requirements.

Q: Why is the main part listed as obsolete?

A: The BFC230341394 (MKT303 series) has been discontinued by the manufacturer. The BFC2373EE394MD (MKT373M series) represents the active equivalent offering continued availability and support.

Q: Are there any electrical performance differences?

A: No. Both parts maintain identical voltage ratings, capacitance values, tolerance bands, dielectric materials, and operating temperature ranges. Electrical performance is equivalent.
