Substitute Part Grouping Explanation

Substitution eligibility for the BFC237051333 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.033 µF (no tolerance variation permitted)
• Tolerance: Must be ±10%
• Voltage Rating - DC: Must be 400V or higher
• Voltage Rating - AC: Must be 220V or higher
• Dielectric Material: Must be Polyester, Metallized
• Operating Temperature Range: Must span -55°C to 105°C or equivalent
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial
• Termination: Must be PC Pins
• Compliance: Must maintain ROHS3 compliance and REACH Unaffected status

The substitute part BFC237251333 meets all electrical equivalence criteria. Mechanical differences in physical dimensions and lead spacing are permissible when the through-hole radial package and PC pin termination remain consistent with PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

Both BFC237051333 and BFC237251333 are active production components manufactured by Vishay Beyschlag/Draloric/BC Components with full ROHS3 compliance and REACH Unaffected status. Selection between these parts is based on:

BFC237051333 (MKT370 Series): Suitable for applications with compact PCB layouts requiring minimal footprint. Automotive-grade rating (AEC-Q200) qualifies this part for automotive applications. Lead spacing of 0.200" (5.08mm) accommodates standard through-hole PCB designs with tighter component density.

BFC237251333 (MKT372 Series): Suitable for general-purpose applications with standard PCB layouts. Lead spacing of 0.394" (10.00mm) accommodates through-hole designs with wider component spacing. Higher inventory availability (1115 units) may support shorter lead times.

Both parts deliver identical electrical performance across the specified voltage, capacitance, tolerance, and temperature operating ranges. PCB layout compatibility must be verified against lead spacing and physical dimensions before final component selection.

Frequently Asked Questions (FAQ)

Q: Can BFC237251333 replace BFC237051333 in any application?

A: Electrical substitution is valid when the application tolerates the physical dimension and lead spacing differences. BFC237251333 has a lead spacing of 0.394" (10.00mm) compared to BFC237051333 at 0.200" (5.08mm). PCB layout must accommodate the larger spacing before substitution is implemented.

Q: Are there differences in reliability or lifespan between these parts?

A: Both parts are manufactured by the same supplier, use identical dielectric material (Polyester, Metallized), and operate across the same temperature range (-55°C to 105°C). Both feature Long Life characteristics. Reliability is equivalent when used within specified electrical and environmental parameters.

Q: What is the significance of the MKT370 and MKT372 series designations?

A: Series designations indicate different mechanical packaging within the same electrical specification family. MKT370 and MKT372 represent different physical form factors while maintaining identical capacitance, voltage rating, tolerance, and dielectric properties.

Q: Does lead spacing affect electrical performance?

A: Lead spacing is a mechanical parameter that does not affect electrical performance. It determines PCB hole pattern compatibility and component density on the circuit board. Electrical characteristics remain identical regardless of lead spacing.

Q: Are both parts suitable for automotive applications?

A: BFC237051333 carries AEC-Q200 automotive-grade certification. BFC237251333 is rated for general-purpose applications. Automotive application requirements must reference the specific AEC-Q200 certification of BFC237051333 if automotive qualification is mandatory.
