Frequently Asked Questions (FAQ)

Q: Can BFC236645393 be used as a direct replacement for BFC236545393? A: Yes. Both parts share identical capacitance (0.039 µF), tolerance (±10%), voltage ratings (250V DC / 160V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), mounting type (through hole radial), physical dimensions (10.00mm x 4.00mm), height (13.50mm max), lead spacing (5.00mm), and termination (PC pins). No circuit modifications are required.

Q: What is the primary reason for substitution? A: BFC236545393 is classified as obsolete. BFC236645393 is the active equivalent from the same manufacturer, providing continued component availability for production and repair applications.

Q: Are there any packaging differences between these parts? A: BFC236645393 is supplied in Tape & Box (TB) packaging. Both parts maintain identical physical form factors and are compatible with standard through-hole assembly processes.

Q: Do both parts meet the same compliance standards? A: Yes. Both BFC236545393 and BFC236645393 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.25.0010) classifications.

Q: What is the difference between the MKT365 and MKT366 series designations? A: Both are Vishay film capacitor series with identical electrical and mechanical specifications for this 0.039 µF 250V rating. The series designation reflects internal product line organization but does not affect functional equivalence.
