Engineering Selection Recommendations
Both the BFC238340683 and B32654A1683J000 maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. The substitute part offers a 200V DC voltage rating advantage (1600V vs. 1400V), providing additional safety margin in high-voltage applications.
The B32654A1683J000 carries AEC-Q200 automotive qualification, which may be relevant for applications requiring automotive-grade reliability. The operating temperature range of the substitute extends to 100°C maximum compared to 105°C for the original part; this difference is negligible for most industrial applications but should be evaluated if operation near the upper temperature limit is required.
Physical dimensions show minor variations: the substitute is slightly narrower (11.00mm vs. 13.00mm) and shorter (21.00mm vs. 23.00mm), which may provide layout advantages in space-constrained designs while maintaining identical lead spacing for PCB compatibility.
Frequently Asked Questions (FAQ)
Q: Can the B32654A1683J000 be used as a direct replacement for the BFC238340683?
A: Yes. Both parts share identical capacitance (0.068 µF), tolerance (±5%), AC voltage rating (500V), dielectric material (polypropylene metallized), mounting type (through hole radial), lead spacing (27.50mm), and termination (PC pins). The substitute provides higher DC voltage rating (1600V vs. 1400V).
Q: What are the key differences between these parts?
A: The primary differences are manufacturer, DC voltage rating (1600V vs. 1400V), operating temperature maximum (100°C vs. 105°C), physical dimensions (slightly smaller for the substitute), and certifications (AEC-Q200 for the substitute). Electrical performance and capacitance characteristics remain equivalent.
Q: Will the smaller physical dimensions of the B32654A1683J000 affect PCB layout?
A: No. The lead spacing remains identical at 27.50mm, ensuring direct PCB footprint compatibility. The reduced length and width may actually provide layout flexibility in space-constrained applications.
Q: Are both parts suitable for high-pulse and DV/DT applications?
A: The BFC238340683 is specified for high-pulse and DV/DT applications. The B32654A1683J000 is specified for DC link, DC filtering, high-pulse, and DV/DT applications, confirming suitability for the same application categories.
Q: What is the inventory status for each part?
A: BFC238340683 has 728 units in stock. B32654A1683J000 has 1620 units in stock, providing greater availability for procurement planning.
