Original Siemens 6sn1112 Power Supply Board A5E02026600 A5EO2O266OO

Siemens A5E02026600 | Industrial Drive & Automation Spare Part PCB — A5E Series, Germany

Part Number: A5E02026600

Manufacturer: Siemens AG (Germany)

Product Type: Spare Part PCB — Industrial Drive / Automation System Board

Part Series: A5E (Siemens Internal Spare Part Number Series)

Application: Siemens industrial drives, automation systems, and associated electronics

Overview

The A5E02026600 is a Siemens spare-part printed circuit board identified under Siemens' A5E internal component numbering system.

The A5E designation is Siemens' structured reference for replacement and spare-part components used across its industrial drive, CNC, automation, and power electronics product lines. 

Boards in the A5E series serve as verified replacements for specific assemblies within Siemens drive and automation equipment — covering control boards, gate driver assemblies, interface boards, power boards, and functional sub-assemblies used in the manufacture and servicing of Siemens' industrial product portfolio.

Siemens industrial drive systems — across platforms including SINAMICS, SIMOVERT MASTERDRIVES, MICROMASTER, SIMOREG, and SIMODRIVE — contain numerous distinct PCBs and electronic sub-assemblies, each identified by a unique A5E part number in the Siemens spare parts catalogue. When a specific electronic sub-assembly within a drive or automation system requires replacement, the correct A5E part number identifies the exact compatible board.

This ensures that replacement components are built to the same specification and quality standard as the original part in the manufactured equipment.

The A5E02026600 is sourced from Siemens' established manufacturing and supply base in Germany, reflecting the build quality and component standards that underpin Siemens' reputation in industrial automation.

The board is engineered for service in the demanding thermal, electrical, and vibration environments that industrial drive equipment typically operates in.

Key Specifications

A5E Series Spare Parts — How Siemens Identifies Replacement Boards

Siemens uses a structured internal part numbering system for spare and replacement components. The A5E prefix identifies a spare part that is used in, or manufactured as a replacement for, a component in a Siemens industrial product.

The A5E number is the definitive identifier for spare parts ordering — it cross-references directly to the specific PCB assembly, sub-board, or electronic module needed for a particular repair.

For industrial drive systems, every replaceable PCB assembly within the drive unit carries an A5E reference number printed on the board label or documented in the drive's spare parts list in the service manual.

The service manual or spare parts catalogue for the drive in question lists the A5E numbers for all serviceable board assemblies, allowing maintenance engineers to identify and order the exact board needed for a repair.

The A5E02026600 belongs to this category — a board that serves a defined function within its host Siemens drive or automation system.

Its correct identification is through the Siemens spare parts system or the specific service documentation for the equipment in which it is installed.

Industrial Drive PCB Reliability — Service Environment

Siemens industrial drive PCBs are engineered to operate in the electrical environment of a drive cabinet.

This means tolerance for high-frequency switching noise generated by the IGBT transistors in the same cabinet, resistance to temperature cycling as the drive loads up and cools down, and resistance to vibration from the machinery to which the drive is connected. 

Siemens specifies environmental operating conditions for each product class and validates that boards like the A5E02026600 meet these requirements through its standard qualification processes.

A Siemens spare-part board ordered through legitimate channels carries the same quality credentials as the board originally fitted in the equipment — it is built to the same specifications, uses the same or equivalent components, and passes the same outgoing quality checks.

This is the distinction between an authentic Siemens A5E spare part and a counterfeit or generic substitute, which may superficially resemble the original but lack the validation and component traceability that Siemens applies to its spare parts production.

Ordering and Identification

The A5E02026600 board should be ordered by specifying the exact part number to ensure the correct assembly is supplied.

In Siemens' spare parts system, the A5E number is the primary identifier. The host equipment's serial number and type designation may also be requested to verify compatibility.

For maintenance engineering teams managing installed Siemens drive equipment, maintaining a record of the A5E numbers for critical replaceable boards in each drive type — drawn from the equipment's service manual — is good practice.

This allows rapid identification and ordering of the correct spare when a board failure occurs, minimising the diagnostic delay that comes from needing to identify the part number at the time of a fault.

FAQ

Q1: How do I confirm that A5E02026600 is the correct board for my Siemens drive before ordering?

Locate the spare parts section of the drive's service manual or maintenance instructions. This document lists all replaceable PCB assemblies with their A5E part numbers and the specific drive positions they occupy.

Cross-reference the board's physical label on the installed unit with the A5E number in the documentation. If the A5E02026600 number appears on the board's label and in the documentation for the affected board position, it is the correct spare.

Q2: Can A5E spare parts from Siemens be substituted with generic or third-party alternatives?

Generic substitutes may be available but carry significant risks: component differences can result in incorrect performance, failure under the drive's specific operating conditions, or, in worst cases, consequential damage to connected components.

Siemens' A5E spare parts are validated for the specific electrical and thermal environment of their host equipment.

For production-critical drives, using authentic Siemens A5E spare parts is the safest approach. 

Third-party repairs using non-OEM boards typically void Siemens' ability to provide support for subsequent failures.

Q3: The drive fault occurred after a power surge event. If the A5E02026600 board is the damaged component, will replacing it restore the drive to normal operation?

A power surge can damage multiple components simultaneously — the A5E02026600 board, the IGBT modules, capacitors, and fuses may all be affected. Replacing the board alone restores full drive function only if the board is the sole damaged component.

After board replacement, a systematic inspection of other drive components — particularly the DC bus capacitors and any surge suppression components — is advisable before returning the drive to service.

Q4: Is the A5E02026600 board interchangeable across different Siemens drive models?

A5E spare part boards are typically specific to a defined set of drive models and configurations.

Two different Siemens drive models may use the same A5E board if they share the same power section or control board design, but this cannot be assumed without confirming compatibility through the documentation for each drive model. 

Always verify that the A5E number in the spare parts documentation of the specific drive model matches before installing a board.

Q5: What ESD precautions are required when handling the A5E02026600 board?

Industrial PCBs of this type contain CMOS and low-power IC devices that are susceptible to electrostatic discharge.

Handle the board only with an approved ESD wrist strap connected to an appropriate grounding point. Work on a conductive or dissipative surface. 

Do not place the board on insulating materials such as cardboard or plastic bags. When not installed, store the board in conductive anti-static packaging. 

These precautions prevent static-induced damage that may not produce an immediate failure but can cause latent defects that result in premature board failure in service.
