Frequently Asked Questions (FAQ)

Q: Are R46KF310000M1K and R46KF3100JMP0K true substitutes for R46KF310040P0K?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (0.1 µF, ±10% tolerance, 560V DC rating) and mechanical dimensions (13.00mm x 6.00mm, 10.00mm lead spacing, radial through-hole configuration). All three parts are from the KEMET R46 series and share the same dielectric material, operating temperature range, and compliance certifications.

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

A: Yes. The substitute parts have identical package dimensions, lead spacing, and mounting type (radial through-hole). No PCB layout modifications are required for substitution.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.25.0010. Regulatory compliance is equivalent across all three part numbers.

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

A: The part numbers reflect different internal KEMET manufacturing codes or packaging lot designations. The electrical and mechanical specifications are identical, making them functionally interchangeable for circuit design purposes.

Q: Which part should I select if all are available?

A: Selection should be based on inventory availability and procurement lead time. R46KF3100JMP0K currently has the highest inventory level (2752 Pcs), which may provide supply chain advantages for high-volume applications.
