Obsolete components? No problem!
We can offer help for obsolete components.
The number of components discontinued by the supply industry is steadily increasing. This sometimes has far-reaching implications for vehicle keepers and operators. The aim is to plan ahead. Not taking provisions at an early stage may have negative financial consequences.
This is why we offer a comprehensive obsolescence management for electronic components. For selected components we also offer 3D printing for faster availability of spare parts.
We keep an eye on the market of spare and component parts as well as on developments on the supplier side or in the price segment. We keep you informed about the discontinuation of spare parts and components and also offer solutions.
Our services in Detail
Obsolescence risk analyses
Periodic redesigns of entire rail vehicles are carried out to enable technical upgrades to be implemented, interior fittings and designs to be modernised and, more importantly, worn components and structural parts of the rail vehicle to be repaired and critical technical systems to be stabilised. These redesigns should be used to ensure the long-term availability of (potentially) obsolete components and assemblies.
To identify the risks, an obsolescence robustness analysis is conducted that reveals the risks and serves as a basis for developing solutions. The robustness analysis consists of the milestones data collection, analysis of the maintenance situation, assessment of the ageing condition and determination of possible solutions.
The analysis results in a coordinated obsolescence strategy that is then implemented. The strategy can be implemented in part by means of a redesign, especially if the substitution of the entire system was determined to be the more favourable solution. In all other cases such as long-term repairs, refurbishments, stabilisation of spare parts supply, no provision needs to be made in the redesign since neither the system nor the installed components are changed.
End-of-life inventory ensures the availability of materials through stock-holding up until the end of the life of the rail vehicle. We have storage spaces for virtually all components. These are fitted with suitable long-term storage equipment such as nitrogen cabinets or special packaging/containers. To prolong the service life, conservation methods, e.g. energising, are carried out.
Substitution refers to the replacement of a component or assembly with a solution involving equivalent installation and operation procedures. If substitution is deemed appropriate, we will provide the equivalent replacement. Adaptation refers to the replacement of an obsolete component with a solution that does not involve equivalent installation and operation procedures. Extensive tests ensure that the substitute or adapted solution is in fact equivalent and that the processes are documented.
If no suitable substitute is available or if a cost-effectiveness analysis indicates that a redesign is the most economical solution, we will use the original specifications and requirements or a sample device to create a new documentation with identical specifications. First, we will reverse-engineer the circuity of the board and digitise it as closely as possible to the original. After this the required quantity can be produced. We use experienced service providers for production. By producing a 1:1 replica, the electrical and mechanical properties of the original part are retained, keeping costly re-qualifications to a minimum. Qualification tasks, e.g. regarding the suitability for railway use (DIN 50155), are also carried out by the service provider.
Just like mechanical components, vehicle electronics are subject to wear and contamination. This has a negative effect on proper functioning and, in the worst case, can result in a total failure. We remove contamination, quickly replace old electronic components as soon as they reach their wear limit, professionally clean components and repair damage – even mechanical damage to metal sheets, welded or bonded joints and paintwork. If possible, we will fix design flaws and protect electronic components with protective coatings.
We restore the parts and components we remove from vehicles so that they are fully functional again. Thanks to our many years of experience in repairing old parts, we have stocks of electronic components from older vehicles.
