Siemens Industrial Parts — New, Discontinued & Obsolete
Apex sources Siemens automation and control components for maintenance teams, system integrators, and procurement departments across Singapore, Southeast Asia and Australia — including discontinued and obsolete parts that Siemens no longer manufactures, new and reconditioned. If your SIMATIC system is approaching end-of-life, we can help with replacement planning to avoid unplanned downtime, sourcing a direct replacement or a compatible spare. Our component lifecycle management approach means panels running Siemens gear stay documented well before a part is discontinued.
PLCs
SIMATIC S7-300, S7-1200, and S7-1500 series controllers — including obsolete S7-300 CPU modules no longer sold new by Siemens.
Drives
SINAMICS G120, V20, and legacy MICROMASTER VFDs and drive systems, including discontinued models still supported through our sourcing network.
Switchgear
SIRIUS contactors, overload relays, and circuit breakers — current production and obsolete replacements for panels still running older Siemens gear.
