The European Space Components Coordination (ESCC) Qualification Parts List (QPL) is a vital document for the aerospace and defence industries. The latest edition, Edition 251, released in June 2024, includes significant updates that impact several manufacturers and their components. This blog post will delve into the specific changes in this edition, including certificate extensions and removals, and their implications for the industry.
Certificate extension
313F, Kongsberg Defence & Aerospace Norway
One of the significant updates in Edition 251 is the extension of the certificate for Kongsberg Defence & Aerospace Norway. This certificate includes SAW Filters, detailed in ESCC 3502/002.
SAW filters: Overview and importance
SAW Filters are critical components in aerospace and defence applications due to their ability to provide high-frequency signal processing with excellent stability and reliability. These filters are used for various functions, including bandpass, resonator, notch, and low-loss impedance elements.
Certificate removal
317E, LEACH Sarralbe (France)
Another critical update in this edition is the removal of the certificate for LEACH Sarralbe (France). The removal was due to unsatisfactory maintenance of qualification testing and a lack of sales. This certificate included latching relays based on type M402, detailed in ESCC 3602/004.
Impact on the market
The removal of this certificate can lead to a gap in the market for these relays. Manufacturers relying on these specific relays will need to find alternative certified suppliers to ensure their products meet the required standards. This change may also encourage other component manufacturers to maintain rigorous quality control to avoid similar issues.
