Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC237041332 is permissible when the following conditions are met:

Primary Substitution Criteria:

• Capacitance value remains 3300 pF (no deviation)
• Tolerance specification remains ±10%
• Dielectric material remains polyester, metallized
• Mounting type remains through hole radial
• Physical dimensions and lead spacing remain identical
• Operating temperature range remains -55°C to 105°C
• Automotive qualification (AEC-Q200) is maintained
• RoHS3 compliance is maintained

Voltage Rating Flexibility: The DC voltage rating may be increased from 250V to higher values (such as 400V) without affecting circuit functionality, provided the application does not impose a maximum voltage constraint. Higher voltage ratings provide additional design margin and reliability in the same physical package.

Parameter Comparison

Engineering Selection Recommendations

BFC237041332 Selection: Select this part when the application circuit is designed for 250V DC operation and 160V AC operation. This part carries active product status with established supply availability.

BFC237051332 Selection: Select this part when the application circuit operates at or below 250V DC and 160V AC, as the higher voltage rating (400V DC / 220V AC) provides additional safety margin without altering electrical performance. This substitute maintains identical capacitance, tolerance, temperature range, and physical form factor. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. The substitute offers higher inventory availability (2200 units versus 889 units).

Both parts are manufactured by the same supplier within the MKT370 series, ensuring consistent quality and reliability standards for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can BFC237051332 be used in place of BFC237041332? A: Yes. The BFC237051332 maintains identical capacitance (3300 pF), tolerance (±10%), dielectric material (polyester, metallized), operating temperature range (-55°C to 105°C), physical dimensions, lead spacing, and automotive qualification (AEC-Q200). The higher voltage rating does not affect compatibility in circuits designed for 250V DC or lower.

Q: What is the difference between these two parts? A: The primary difference is the voltage rating. BFC237041332 is rated 250V DC / 160V AC, while BFC237051332 is rated 400V DC / 220V AC. All other electrical and mechanical specifications are identical.

Q: Are these parts interchangeable on the PCB? A: Yes. Both parts have identical physical dimensions (0.283" L x 0.098" W), lead spacing (0.200"), and radial through-hole mounting configuration. No PCB layout modifications are required.

Q: Do both parts meet automotive standards? A: Yes. Both BFC237041332 and BFC237051332 carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting the same regulatory and quality requirements.

Q: Which part should I select for new designs? A: For new designs, BFC237051332 is recommended when circuit voltage does not exceed 250V DC, as the higher voltage rating provides additional design margin and the part has higher inventory availability (2200 units in stock).
