Overview
Siemens is the largest brand in the Palm Parts Solution catalog: 1,419 part numbers across 18 product families and 37 series.
Drives dominate the listing. Variable frequency drives account for 430 part numbers, led by the Sinamics range (397) with Micromaster and SIMOVERT MasterDrives alongside it. Servo drives and motion control add 170, split mainly between Simodrive 611 (91) and Sinamics S120 (79). Siemens PLCs total 182 across SIMATIC S7-1500, S7-1200, S7-300, S7-400 and LOGO!.
Control and panel products follow: SIRIUS motor protection and starters (58), SIRIUS contactors (55), industrial networking including Scalance switches and communication processors (49), SITOP power supplies (47), Sinumerik CNC (38), SIMATIC HMI panels (25), 3SU command and signaling devices (23) and DC drives including SIMOREG 6RA70 and Sinamics DC Master 6RA80 (20).
Each family page carries its own technical detail, so this hub links out rather than repeating it. Siemens part numbers begin with an MLFB order code (6ES7, 6SL3, 6AV2, 3RT, 3RV and so on) — searching by that code is the most reliable route to a specific item. Condition is stated per product; send the MLFB number for a quote.

Frequently asked questions
Where can I buy Siemens PLCs and automation parts?
Sourcing Siemens SIMATIC controllers comes down to whether the platform is still in current production.
Current platforms — S7-1200 and S7-1500 — are available through authorized Siemens distribution with factory configuration support and standard lead times.
Legacy platforms — S7-300, S7-400, S5 and older SIMATIC HMI panels — are increasingly limited in authorized channels. Independent automation specialists such as Palm Parts Solution source these from new old stock, surplus and refurbished inventory.
Identify the part by its MLFB order number (for example 6ES7315-2EH14-0AB0). The trailing digits carry the functional version; a different suffix can mean different memory size, firmware or interface. Match the MLFB exactly, then confirm firmware version against your TIA Portal or STEP 7 project.
Before you buy, verify: the MLFB, firmware/functional version, the memory-card requirement, the communication interface (PROFIBUS versus PROFINET), and whether the seller states condition — new, surplus or refurbished — and the warranty term.
To see what is currently listed, browse Siemens PLCs. For migration planning, see the S7-300 to S7-1500 migration guide or the S7-1500 module compatibility matrix.

Is the Siemens S7-300 still available?
Yes, but with important caveats. Siemens has officially moved the SIMATIC S7-300 series to legacy status, initiating its phased withdrawal. While they are no longer recommended for new installations, complete product discontinuation takes time, meaning spare parts remain vital for existing systems.
At Palm Parts Solution, we understand that immediate migration isn't always feasible for maintenance engineers and plant managers. To help you avoid costly downtime, we maintain a comprehensive inventory of new, surplus, and certified refurbished Siemens PLC Spare Parts, including S7-300 CPUs, digital/analog I/O modules, and power supplies.
However, for long-term operational resilience, OEMs and facilities should actively plan their transition to the modern S7-1500 controller family. The S7-1500 offers superior diagnostics, faster backplane buses, and TIA Portal integration. For step-by-step advice on managing this hardware and software transition smoothly, please read our Siemens S7-300 to S7-1500 Migration Guide. We are here to support your current lifecycle needs while helping you prepare for future upgrades.
What replaces the Siemens S7-200?
For industrial facilities looking to upgrade from the legacy Siemens SIMATIC S7-200, the direct, modern successor is the SIMATIC S7-1200 controller. Introduced to bridge the gap between micro-PLCs and high-performance automation, the S7-1200 offers a seamless migration path with significantly enhanced processing power, integrated PROFINET ports, and native integration into the TIA Portal engineering framework.
For maintenance engineers and OEMs planning this transition, key factors include:
- Communications: The S7-1200 relies on Ethernet-based PROFINET, replacing the older serial PPI/MPI protocols of the S7-200.
- Software Migration: Code written in STEP 7-Micro/WIN cannot be executed directly; it requires conversion or rebuilding within the TIA Portal environment.
- I/O and Footprint: While the physical dimensions and wiring hookups differ, the S7-1200 features a compact-class modular design that easily fits existing DIN rail layouts.
