Frequently Asked Questions (FAQ)

Q: Can the B32524Q3475K000 be used as a direct replacement for the MKS4F044706B00KSSD?

A: Yes. Both parts have identical capacitance (4.7 µF), voltage ratings (250V DC / 160V AC), tolerance (±10%), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), physical dimensions (31.50mm × 11.00mm × 21.00mm), lead spacing (27.50mm), and AEC-Q200 automotive qualification. The parts are mechanically and electrically interchangeable.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts have identical radial through-hole package dimensions, lead spacing, and termination type (PC pins). PCB hole patterns and mounting procedures are identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the MKS4F044706B00KSSD and B32524Q3475K000 carry AEC-Q200 automotive qualification, meeting automotive industry reliability and quality standards.

Q: What is the difference between the MKS 4 series and the B3252 MKT series?*

A: Both are established polyester film capacitor series from their respective manufacturers (WIMA and EPCOS - TDK Electronics). The series designation reflects manufacturer product line organization but does not affect electrical or mechanical compatibility for this specific part number comparison.

Q: Can I mix these two part numbers in the same production batch?

A: Yes. Since the parts are parametrically identical with matching electrical specifications, mechanical dimensions, and automotive certifications, they can be used interchangeably within the same circuit design and PCB layout.

Q: What is the lead spacing specification and why is it important?

A: The lead spacing is 27.50mm (1.083"). This dimension determines the PCB hole pattern pitch. Both parts have identical lead spacing, ensuring compatibility with the same PCB footprint design.

Q: Are there any temperature or voltage derating considerations?

A: Both parts operate across the identical temperature range of -55°C to 125°C with the same voltage ratings (250V DC / 160V AC). No differential derating applies between these parts.
