TAIYO YUDEN
Taiyo Yuden UMK107AB7105KA-T closely matches the 1uF 50V X7R 0603 target.
CL10B105KB8NQNC is a 1uF 50V X7R 0603 MLCC. The closest listed alternate is Taiyo Yuden UMK107AB7105KA-T, pending FAE review.
Check DC bias and derating.
Low only for 0603 candidates.
Passive MLCC, no firmware.
Avoid obsolete low-voltage options.
Direct replacement for CL10B105KB8NQNC should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use UMK107AB7105KA-T first; use others only with parameter or PCB changes.
Voltage derating, DC bias capacitance loss, and footprint mismatch on non-0603 options.
