All listed alternate parts are from the Siemens 3SU1 22mm series with a 22.3mm panel cutout and box packaging. They differ from the primary in that illumination is absent, requiring the reader to apply contact blocks for circuit completion.

Why these are catalog-similar: Same manufacturer, shared 22mm panel-mount form factor, and identical encapsulation packaging. The primary part carries a factory-integrated red LED source rated at 24 VAC/DC, while the alternates are bare non-illuminated pushbutton heads that depend on external contact blocks for electrical function.
