Substitute Part Grouping Explanation

Substitution of the BFC237035822 is permissible when the following conditions are met:

The substitute part must maintain identical capacitance value (8200 pF) and tolerance (±10%). The dielectric material, operating temperature range, mounting type, package configuration, and physical dimensions must remain unchanged. The substitute part must retain automotive qualification (AEC-Q200) and RoHS3 compliance status.

The primary allowable variation is voltage rating. A substitute part with a higher DC voltage rating (400V versus 250V) is functionally compatible because higher voltage-rated capacitors operate safely in lower voltage applications. The AC voltage rating may correspondingly increase (220V versus 160V) as a result of the higher voltage rating classification.

Packaging format changes from Tape & Box to Bulk are acceptable when supply chain or inventory management requirements permit, provided all electrical and mechanical specifications remain consistent.

Parameter Comparison

Engineering Selection Recommendations

The BFC237051822 qualifies as a direct substitute for the BFC237035822 based on maintained electrical and mechanical compatibility. Both parts are manufactured by the same supplier within the same MKT370 series, share identical capacitance, tolerance, dielectric composition, temperature operating range, and physical footprint. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance.

The BFC237051822 provides a higher voltage rating (400V DC / 220V AC) compared to the original specification (250V DC / 160V AC). This higher rating ensures safe operation in applications originally designed for the lower voltage specification. The substitute part is suitable for direct replacement in automotive circuits where the 250V DC rating was previously specified.

Packaging differences (Tape & Box versus Bulk) do not affect electrical or mechanical performance and may be selected based on assembly process requirements or inventory management preferences.

Frequently Asked Questions (FAQ)

Q: Can BFC237051822 replace BFC237035822 in all applications?

A: Yes, the BFC237051822 is electrically and mechanically compatible with BFC237035822 for all automotive applications originally specified for the 250V DC rated part. The higher voltage rating of the substitute ensures safe operation across the original design voltage range.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical radial package dimensions: 7.20mm length, 2.50mm width, 6.50mm maximum seated height, and 5.08mm lead spacing. Direct board-level substitution is possible without PCB redesign.

Q: What is the significance of the voltage rating difference?

A: The BFC237051822 operates at 400V DC compared to the 250V DC rating of BFC237035822. Higher voltage-rated capacitors are suitable for use in lower voltage applications. This substitution does not compromise performance and may provide additional design margin in voltage-sensitive circuits.

Q: Do both parts meet the same automotive standards?

A: Yes. Both BFC237035822 and BFC237051822 are AEC-Q200 qualified and ROHS3 compliant, meeting identical automotive reliability and environmental requirements.

Q: What is the difference between Tape & Box and Bulk packaging?

A: Tape & Box packaging provides pre-packaged quantities suitable for automated pick-and-place assembly. Bulk packaging offers loose components for manual assembly or alternative handling processes. Both formats contain the same electrical component with no performance difference.
