Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC237045152 is permissible when the following conditions are met:

• Capacitance value remains 1500 pF
• Tolerance remains ±10%
• Dielectric material remains polyester, metallized
• Operating temperature range remains -55°C to 105°C
• Mounting type remains through hole
• Package and case remain radial
• Physical dimensions and lead spacing remain identical
• Voltage rating is equal to or greater than the required circuit voltage

The BFC237051152 qualifies as a parametric equivalent because it maintains all core electrical and mechanical specifications while providing a higher DC voltage rating of 400V, making it suitable for applications requiring higher voltage margins or operating in elevated voltage environments.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC237045152 and BFC237051152 are active production parts with identical AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is determined by circuit voltage requirements:

• Use BFC237045152 when the circuit design specifies a maximum operating voltage of 250V DC or 160V AC.
• Use BFC237051152 when the circuit design permits or requires a higher voltage rating of 400V DC or 220V AC, or when higher voltage margin is desired for reliability in automotive environments.

Both parts are suitable for through-hole PCB assembly in automotive applications. Physical footprint compatibility is confirmed across all dimensional parameters, including lead spacing and seated height.

Frequently Asked Questions (FAQ)

Q: Can BFC237051152 be used as a direct replacement for BFC237045152?

A: Yes, when circuit voltage requirements permit. The BFC237051152 maintains identical capacitance, tolerance, dielectric material, operating temperature range, and physical dimensions. The higher voltage rating of 400V DC is compatible with any circuit designed for 250V DC or lower.

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

A: No. Both parts share identical physical dimensions, lead spacing of 0.200" (5.08mm), and radial package configuration. PCB footprints are directly compatible.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both BFC237045152 and BFC237051152 carry AEC-Q200 qualification and are suitable for automotive applications.

Q: What is the difference in voltage rating between these parts?

A: The BFC237045152 is rated for 250V DC and 160V AC. The BFC237051152 is rated for 400V DC and 220V AC. The higher voltage rating of the substitute part provides additional voltage margin without changing any other electrical or mechanical characteristics.
