The 4103/6103 ceramic nozzle has a 0.9 × 0.5 mm pickup tip and a 10.8 mm overall length. Within the SIPLACE 4xxx/6xxx nozzle family, this tip size places it between finer-tip options such as the 4105/6105 and larger pickup geometries such as the 4107/6107. That dimensional difference matters when selecting a nozzle for a particular component footprint: a larger tip is not automatically a better fit if the component’s pickup surface is smaller. The 4103/6103 is listed for 1005 metric-size components (0402 imperial).
P/N 03101981 identifies this ceramic nozzle for compatible C&P20 P/M2/P2 head configurations. Its defining selection criteria are the pickup-face dimensions and the corresponding component package, rather than ceramic construction alone. For a replacement, the original nozzle designation and approved component setup are more useful than choosing by appearance.
