A form-fit compatible upgrade with a higher voltage rating (10V) and lower ESR (0.9 Ohm).
Finding a replacement for the AVX TPSA106K006R1500 10µF 6.3V tantalum capacitor involves matching the 1206 package and capacitance, while carefully considering voltage and ESR ratings. Several upgrades and alternatives exist.
ESR and dielectric type vary significantly between candidates.
Many candidates share the same 1206 package.
There are several pin-compatible parts, but a true 'drop-in' depends on your circuit's sensitivity to ESR. TPSA106K016R1000 is a strong candidate for a drop-in upgrade.
Upgrade to a same-series (TPS) part with a higher voltage rating and lower ESR, such as TPSA106K016R1000.
The main risk is selecting a part with higher ESR, which can compromise performance in decoupling and filtering applications.
