Siemens A6X30140144 — 30mm Illuminated Pushbutton Body
Parametric Comparison: Seed vs Alternates
The reader must qualify all listed alternates independently against the application requirements; numeric similarity does not imply functional equivalence.

Why similar — A6X30140145, A6X30140141, A6X30140149: All four share the same MPN prefix (A6X3014014x), belong to the Siemens 3SU1 30mm series, and carry identical specs for actuator type, illumination, cutout, and block/LED requirements. The trailing digit varies, consistent with color-termination variant coding within the same family.

The A6X30140144 is an illuminated pushbutton body from Siemens' 3SU1 30mm modular series. It requires separate contact blocks and an illumination source (typically an LED module) to form a complete operator. The blue actuator color is encoded in the trailing digit of the MPN.
Family Context
The 3SU1 series uses a trailing-digit MPN scheme where the last digit encodes actuator color. Blue variants in this group occupy MPN suffixes 4 and 7 (A6X30140144, A6X30140177). Non-illuminated versions (A6X30140044) share the same mechanical footprint but omit the illumination source requirement.
