BFC238340912 Equivalent & Substitute Parts

Part Overview

The BFC238340912 is a 9100 pF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, part of the MMKP383 series. This polypropylene metallized radial capacitor is rated for 1400V DC and 500V AC operation across an operating temperature range of -55°C to 105°C. The component is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings and physical dimensions remain compatible with the original application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC238340912 is determined by strict adherence to the following electrical and mechanical parameters:

Capacitance value must remain 9100 pF with ±5% tolerance. Dielectric material must be polypropylene (PP), metallized construction. Mounting type must be through-hole radial configuration. Physical dimensions, including length, width, and height, must match or be compatible with the original footprint. Lead spacing must remain 0.591" (15.00mm). Termination type must be PC pins.

Voltage ratings may be equal to or exceed the original specification. Operating temperature range must encompass or match the original -55°C to 105°C range. Series designation and product status should remain consistent within the MMKP383 family.

Parameter Comparison

Engineering Selection Recommendations

The BFC238350912 is a direct substitute for the BFC238340912 within the MMKP383 series. Both components maintain identical capacitance, tolerance, dielectric material, physical dimensions, and lead spacing. The substitute part features elevated voltage ratings of 1600V DC and 550V AC compared to the original 1400V DC and 500V AC specifications. Both parts are Active in product status and ROHS3 compliant. The substitute part is suitable for applications requiring equivalent or higher voltage performance within the same form factor and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can BFC238350912 replace BFC238340912 in all applications?

A: The BFC238350912 is electrically and mechanically compatible with the BFC238340912. The substitute part maintains identical capacitance (9100 pF), tolerance (±5%), physical dimensions (17.50mm x 8.50mm), lead spacing (15.00mm), and operating temperature range (-55°C to 105°C). The elevated voltage ratings (1600V DC / 550V AC versus 1400V DC / 500V AC) do not restrict compatibility in applications designed for the original part.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the BFC238340912 and BFC238350912 share identical physical dimensions of 0.689" L x 0.335" W (17.50mm x 8.50mm), maximum seated height of 0.591" (15.00mm), and lead spacing of 0.591" (15.00mm). Both use radial through-hole mounting with PC pin termination.

Q: What is the difference between these two parts?

A: The primary difference is the voltage rating. The BFC238350912 is rated for 1600V DC and 550V AC, while the BFC238340912 is rated for 1400V DC and 500V AC. All other electrical and mechanical parameters, including capacitance, tolerance, dielectric material, temperature range, and package configuration, are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the BFC238340912 and BFC238350912 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
