Substitute Part Grouping Explanation

Substitute parts for the BFC237086473 are qualified based on the following criteria:

Electrical Equivalence: Capacitance value (0.047 µF), tolerance (±5%), and voltage ratings (100V DC / 63V AC) must be identical.

Mechanical Compatibility: Radial through-hole package configuration with lead spacing of 0.200" (5.08mm) ±0.010" and maximum seated height of 0.256" (6.50mm) ensures PCB footprint compatibility.

Dielectric Technology: Polyester metallized film construction maintains equivalent electrical performance and frequency response characteristics.

Automotive Compliance: AEC-Q200 qualification is mandatory for automotive applications.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status must be maintained.

Packaging Variation: Substitutes may differ in packaging format (Tape & Box versus Bulk versus Cut Tape) without affecting functional performance, provided all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

BFC237022473 is a direct equivalent from the same manufacturer (Vishay) within the MKT370 series. It maintains identical electrical and mechanical specifications with the primary difference being packaging format (Bulk versus Tape & Box). This substitute is suitable for applications where packaging configuration does not impact assembly or logistics requirements. Both parts share identical product status (Active) and compliance certifications.

B32529C1473J289 from EPCOS - TDK Electronics is functionally equivalent with the following considerations: The operating temperature range extends to 125°C (versus 105°C for the main part), providing enhanced thermal performance. Lead spacing is 0.197" (5.00mm) versus 0.200" (5.08mm), representing a 0.08mm difference that remains within standard PCB tolerance ranges for radial through-hole components. Physical length is 0.287" (7.30mm) versus 0.283" (7.20mm), a 0.04mm variation. Both parts maintain AEC-Q200 qualification and ROHS3 compliance. The B32529C1473J289 utilizes a stacked metallized PET dielectric construction, which is electrically equivalent to the standard polyester metallized design. This part is suitable for applications requiring extended temperature operation or where cross-manufacturer sourcing is necessary.

Frequently Asked Questions (FAQ)

Q: Can BFC237022473 be used as a direct replacement for BFC237086473?

A: Yes. Both parts are manufactured by Vishay within the MKT370 series and maintain identical electrical specifications (0.047 µF, ±5%, 100V DC), mechanical dimensions, and automotive AEC-Q200 qualification. The only difference is packaging format (Bulk versus Tape & Box), which does not affect functional performance.

Q: What is the significance of the lead spacing difference between BFC237086473 and B32529C1473J289?

A: The lead spacing difference is 0.08mm (0.200" versus 0.197"). This variation falls within standard PCB manufacturing tolerances for radial through-hole components and does not prevent PCB footprint compatibility. Both parts are designed for 5.08mm and 5.00mm pitch applications respectively, which are functionally interchangeable in most automotive circuit designs.

Q: Is the extended temperature range of B32529C1473J289 (-55°C to 125°C) a performance advantage?

A: The extended upper temperature limit of 125°C (versus 105°C) provides additional thermal margin in high-temperature automotive environments. However, this is only beneficial if the application requires operation above 105°C. For applications within the -55°C to 105°C range, both parts perform identically.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification and are rated for automotive applications. They are ROHS3 compliant and REACH unaffected, meeting automotive regulatory requirements.

Q: Does the dielectric material difference (standard polyester versus stacked PET) affect electrical performance?

A: No. Both polyester metallized and stacked polyethylene terephthalate (PET) metallized constructions are electrically equivalent for this capacitance value and voltage rating. The dielectric material difference does not impact capacitance, tolerance, voltage rating, or frequency response within the specified operating parameters.

Q: What packaging formats are available for these substitutes?

A: BFC237086473 is supplied in Tape & Box format. BFC237022473 is available in Bulk packaging. B32529C1473J289 is supplied in Cut Tape format. Packaging selection depends on assembly process requirements and order quantity considerations.
