Frequently Asked Questions (FAQ)

Q: Can R463N410000N2M or R463N410050N2M be used as direct replacements for R463N410040N2M?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical capacitance, voltage ratings, dielectric material, operating temperature range, physical dimensions, lead spacing, and termination configuration. Direct substitution is supported without circuit redesign.

Q: Are there any differences in performance between these substitute parts?

A: No. All parts operate within the same electrical specifications: 1 µF capacitance at ±20% tolerance, 630V DC / 310V AC rating, and -40°C to 110°C operating temperature range. Performance in EMI and RFI suppression applications is equivalent.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All parts maintain identical physical dimensions (1.043" L x 0.394" W / 26.50mm x 10.00mm) and lead spacing (0.886" / 22.50mm). PCB layout and mounting holes require no modification.

Q: Are compliance certifications identical across all substitute parts?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8532.25.0020. Regulatory requirements are satisfied uniformly.

Q: What is the difference between these part numbers if they are equivalent?

A: The part numbers reflect internal KEMET manufacturing codes. The differences in the numeric suffix (410040, 410000, 410050) do not indicate functional or electrical differences. All parts belong to the R46 series and maintain identical specifications.

Q: Can I mix these parts in the same design or assembly?

A: Yes. Since all parts are electrically and mechanically equivalent, they can be used interchangeably within the same circuit or assembly without performance degradation or compatibility issues.
