Frequently Asked Questions (FAQ)
Q: Can CL05B103KB5NFNC (50V) be used as a direct replacement for CL05B103KA5NNWC (25V)?
A: Yes. The 50V rated part is electrically and mechanically compatible. Higher voltage rating provides increased design margin without affecting circuit performance in 25V applications. All other parameters (capacitance, tolerance, temperature coefficient, package, operating temperature) remain identical.
Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?
A: Both packaging formats contain identical components. Tape & Reel is supplied on continuous tape for automated high-volume assembly. Cut Tape & Digi-Reel® is supplied in shorter tape segments or alternative reel formats for lower-volume production or manual assembly. Selection depends on procurement volume and assembly equipment compatibility.
Q: Are Murata GRM155R71E103KA01D and GRM155R71E103KA01J interchangeable?
A: Both parts have identical electrical and mechanical specifications. The difference is in the packaging reel configuration (indicated by the final character: D vs. J). They are functionally equivalent but may have different reel quantities or handling requirements. Verify reel specifications with supplier documentation.
Q: Why is CGJ2B2X7R1E103K050BA marked as Obsolete?
A: Obsolete status indicates the manufacturer (TDK) has discontinued production. While existing inventory may be available, this part is not recommended for new designs. Transition to active alternatives such as Samsung Electro-Mechanics CL series parts.
Q: Can I use TMK105B7103KV-F in a new design?
A: No. This Taiyo Yuden part carries "Not For New Designs" status, indicating the manufacturer recommends against use in new product development. Use Active-status alternatives for new designs to ensure long-term supply availability and manufacturer support.
Q: What does AEC-Q200 certification on CL05B103KA5VPNC indicate?
A: AEC-Q200 is an automotive industry standard for passive component reliability. This certification indicates the part meets enhanced testing, qualification, and traceability requirements for automotive applications. Use this part for designs requiring automotive-grade component qualification.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with environmental and hazardous substance restrictions. MSL 1 rating is consistent across all parts, indicating unlimited moisture sensitivity protection during assembly.
Q: What inventory levels should I consider when selecting a substitute?
A: Inventory levels are provided for reference but should not be the primary selection criterion. Prioritize Active product status and compliance requirements. Inventory availability fluctuates; consult current supplier data for real-time stock information.
