BFC237045222 Equivalent & Substitute Parts

Part Overview

The BFC237045222 is a 2200 pF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, designed for automotive applications requiring AEC-Q200 compliance. This radial polyester metallized capacitor operates across a temperature range of -55°C to 105°C and is rated for 250V DC operation. The part is currently active in production with robust inventory availability. Substitute parts are identified when equivalent capacitance and tolerance specifications can be maintained while accommodating different voltage ratings within the same physical package and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC237045222 is determined by the following criteria:

Critical Parameters (Must Match):

• Capacitance: 2200 pF
• Tolerance: ±10%
• Dielectric Material: Polyester, Metallized
• Mounting Type: Through Hole
• Package / Case: Radial
• Physical Dimensions: 7.20mm L x 2.50mm W
• Lead Spacing: 5.08mm
• Series: MKT370
• Operating Temperature Range: -55°C to 105°C

Allowable Variation Parameters:

• Voltage Rating - DC: May be equal to or greater than 250V
• Voltage Rating - AC: May be equal to or greater than 160V

The BFC237051222 qualifies as a parametric equivalent because it maintains identical capacitance, tolerance, physical dimensions, lead spacing, mounting configuration, and temperature range while providing higher voltage ratings (400V DC / 220V AC). This substitution is valid for applications where the circuit voltage requirements do not exceed the original 250V DC specification, as the higher-rated part can safely operate in lower-voltage environments.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC237045222 and BFC237051222 are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. The BFC237051222 substitute part is suitable for applications where component availability or supply chain considerations necessitate an alternative, provided the circuit design operates at or below 250V DC. The higher voltage rating of the substitute part introduces no functional degradation in lower-voltage applications and maintains identical physical footprint compatibility for PCB layout purposes. Both parts carry equivalent compliance certifications and long-life feature designations.

Frequently Asked Questions (FAQ)

Q: Can the BFC237051222 be used as a direct replacement for the BFC237045222?

A: Yes, the BFC237051222 is a direct substitute for applications operating at or below 250V DC. The substitute maintains identical capacitance (2200 pF), tolerance (±10%), physical dimensions (7.20mm x 2.50mm), lead spacing (5.08mm), and temperature range (-55°C to 105°C). The higher voltage rating (400V DC versus 250V DC) does not affect performance in lower-voltage circuits.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts share identical physical dimensions, lead spacing (5.08mm), and radial package configuration. PCB footprints and mounting holes require no modification.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the BFC237045222 and BFC237051222 carry AEC-Q200 ratings and are suitable for automotive applications.

Q: What is the difference between the two parts?

A: The primary difference is the voltage rating. The BFC237045222 is rated for 250V DC (160V AC), while the BFC237051222 is rated for 400V DC (220V AC). All other electrical and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected.
