Engineering Selection Recommendations

All three parts—BFC237051473, BFC237251473, and BFC237351473—are active production components with ROHS3 compliance and equivalent electrical ratings. Selection between these parts depends on printed circuit board layout constraints and lead spacing requirements.

The BFC237051473 features the smallest lead spacing at 0.200" (5.08mm), suitable for compact board designs. The BFC237251473 provides 0.394" (10.00mm) lead spacing with increased availability (5943 units in stock). The BFC237351473 offers the largest lead spacing at 0.591" (15.00mm) for applications requiring wider pad separation.

All parts maintain identical electrical performance across the specified operating temperature range and voltage ratings. Physical dimension differences do not affect electrical substitution when board layout accommodates the alternative lead spacing.

Frequently Asked Questions (FAQ)

Q: Can BFC237251473 replace BFC237051473 in an existing design?

A: Electrical substitution is valid. The parts share identical capacitance, voltage rating, tolerance, and dielectric specifications. Physical replacement requires verification that the printed circuit board accommodates the 0.394" (10.00mm) lead spacing of the BFC237251473, compared to the 0.200" (5.08mm) spacing of the original BFC237051473.

Q: What is the primary difference between these substitute parts?

A: The three parts differ only in lead spacing and physical dimensions. Electrical characteristics—capacitance, voltage rating, tolerance, temperature range, and dielectric material—are identical across all three part numbers.

Q: Are all substitute parts suitable for automotive applications?

A: The BFC237051473 carries AEC-Q200 qualification for automotive use. The BFC237251473 and BFC237351473 are designated for general purpose applications. Automotive-specific requirements must be evaluated against application specifications.

Q: Do the substitute parts have different moisture sensitivity levels?

A: The BFC237051473 lists moisture sensitivity as Not Applicable. The BFC237251473 and BFC237351473 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Can these parts be used interchangeably on the same production line?

A: Electrical interchangeability is confirmed. Manufacturing line compatibility depends on pick-and-place equipment capability to handle different lead spacing configurations. The 0.200" spacing of BFC237051473 differs from the 0.394" and 0.591" spacing of the substitute parts.
