Understanding the Latest Changes in the ESCC QPL (Edition 249, April 2024)

Certificates Extension 

The most recent updates to the ESCC QPL include the extension of several certificates, indicating that the validity date of the certificate is extended. Notably:

• Radiall (France) has extended its certificate 178N to cover RF coaxial attenuators based on type R413, included in ESCC specifications 3403/005 and 3403/008.
• L. Gore & Co (Germany) received a certificate extension 216P for its low frequency wires and cables based on type SPM, included in ESCC 3901/018.
• Exxelia Technologies (Chanteloupe en Brie, France) was granted extensions for two certificates, 315F and 324E, covering different types of ceramic capacitors, which are crucial for managing power supply and electronic circuit stability in harsh space environments.

These extensions reflect ongoing trust in established products and manufacturers, ensuring continuity and reliability in space component sourcing.

Rescoping of Certificates

Radiall’s certificate 185M has been adjusted with the discontinuation of variants 04 and 05 under ESCC 3403/004, replaced by variants from ESCC 3403/006. This rescope RF Coaxial Loads based on type R404, which is crucial for managing RF power within spacecraft communication systems.

Certificate Extension with Remark

Space IC (Germany) had a remarkable addition to certificate 376A. A new remark indicates that the operating range of the supply voltage in standby condition for Variant 1 of the 2A synchronous rectified step-down converter SPPL12420RH has been modified. It now has a maximum of +15V, aligning with the latest issues of ESCC 9102/014. This change reflects adaptations to component specifications based on evolving technical standards and operational feedback.

The modifications and extensions in Edition 249 of the ESCC QPL signify continual advancement and adaptation in space technology components. For businesses and engineers in the space sector, these changes are crucial for compliance and competitiveness. Staying updated with these modifications ensures that designs and products are not only compliant but also incorporate the latest in technology and reliability standards.
