Certified Space-Grade Components for Aerospace Innovation

High-Reliability Space-Approved Electronic Components and Systems for Space Applications

Standards, Qualification, and European Space Initiatives

When designing electronics for space platforms (satellites, launch vehicles, rovers, and deep-space systems) component selection is one of the most critical factors in mission success. Electrical, electronic, and electromechanical (EEE) components must withstand radiation exposure, extreme thermal variations, mechanical stress, vacuum, and long operational lifetimes without maintenance. Each component must deliver consistent reliability throughout the entire mission cycle.

To coordinate and standardise efforts in this field, the European Space Components Coordination (ESCC) was established in 2002, bringing together ESA, national and international public space organisations, component manufacturers, and user industries. The ESCC works to harmonise product specification, development, evaluation, and qualification, ensuring strategic availability of high-performance EEE components for both institutional and commercial space programmes.

The Role of a Specialist Distributor

Sourcing ESCC-approved products that meet stringent space specifications often requires extensive research, supplier engagement, and evaluation. A specialist distributor such as Rhopoint Components streamlines this process—bringing together a wide range of space-ready components from qualified suppliers.

We can provide Commercial Off-The-Shelf (COTS) components for early development phases, with certification for space use arranged later, reducing vendor complexity and easing procurement. Sharing a bill of materials (BOM) with us allows our team to propose a tailored, optimised solution across multiple suppliers.

Manufacturers benefit too—partnering with Rhopoint increases visibility of their space-approved products within a highly targeted customer base, without additional marketing overheads. We also manage end-of-life (EOL) notifications, helping customers secure last-time buys, find approved alternatives, or even source custom solutions.

With decades of experience in aerospace and defence, Rhopoint Components offers expert guidance on EEE components that comply with ECSS, ESCC and MIL-PRF (e.g. MIL-PRF-55342) standards that are acknowledged and published by NASA and ESA.

Trusted Support for Mission-Critical Projects

Our technical sales team offers in-depth application knowledge, assisting with component selection, qualification requirements, and compliance documentation. We work with leading manufacturers such as Isabellenhütte, Cissoid, Exxelia Ohmcraft, and ISOCOM, ensuring you receive only the most reliable components for your designs.
