Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

C0603C393K5RAC7867 (KEMET) and KGM15BR71H393KT (KYOCERA AVX) are direct functional equivalents to the CL10B393KB8SFNC. Both parts maintain identical electrical specifications (0.039 µF, ±10%, 50V, X7R) and mechanical compatibility within the 0603 package envelope. All three parts are ROHS3 compliant and REACH unaffected. Selection between these direct equivalents is based on procurement availability and supply chain requirements.

Upgraded Tolerance Selection:

C0603C393J5RAC7867 (KEMET) and KGM15BR71H393JT (KYOCERA AVX) provide tighter tolerance specifications (±5%) while maintaining all other electrical and mechanical parameters. These upgrades are suitable for applications requiring improved capacitance accuracy without circuit redesign. Both parts are ROHS3 compliant and REACH unaffected.

Upgraded Voltage Rating Selection:

C0603C393K1RAC7867 (KEMET) provides a 100V voltage rating while maintaining the 0.039 µF capacitance and ±10% tolerance. This upgrade is suitable for applications requiring higher voltage margin or operating in elevated voltage environments. The part is ROHS3 compliant and REACH unaffected.

Regulatory and Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. Moisture Sensitivity Level 1 (Unlimited) is consistent across all parts, eliminating moisture handling concerns during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can C0603C393K5RAC7867 directly replace CL10B393KB8SFNC without circuit modification?

A: Yes. C0603C393K5RAC7867 is a direct equivalent with identical capacitance (0.039 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), and package (0603). No circuit modification is required.

Q: What is the difference between the direct equivalent and upgraded tolerance parts?

A: Direct equivalents (C0603C393K5RAC7867, KGM15BR71H393KT) have ±10% tolerance. Upgraded tolerance parts (C0603C393J5RAC7867, KGM15BR71H393JT) have ±5% tolerance, providing tighter capacitance accuracy. All other specifications remain identical.

Q: Can I use C0603C393K1RAC7867 (100V) in place of the 50V rated CL10B393KB8SFNC?

A: Yes. The 100V rated C0603C393K1RAC7867 is electrically and mechanically compatible. Higher voltage rating provides additional safety margin and is suitable for applications where voltage headroom is beneficial. No circuit modification is required.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within 0603 standard tolerances. KEMET parts (C0603C393K5RAC7867, C0603C393J5RAC7867, C0603C393K1RAC7867) have thickness of 0.034" (0.87mm). KYOCERA AVX parts (KGM15BR71H393KT, KGM15BR71H393JT) have thickness of 0.037" (0.95mm). Both are within 0603 package specifications and suitable for standard PCB assembly processes.

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

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the CL10B393KB8SFNC. Moisture Sensitivity Level 1 (Unlimited) is consistent across all parts.

Q: Which substitute part has the highest inventory availability?

A: KGM15BR71H393KT (KYOCERA AVX) has the highest inventory with 102,361 pieces available, followed by KGM15BR71H393JT with 31,095 pieces. KEMET parts range from 5,250 to 17,481 pieces.

Q: Can I mix different manufacturers' parts in the same assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 0603 package. Mixed manufacturer sourcing is acceptable from an engineering compatibility standpoint, though procurement and quality assurance processes should address any internal requirements.
