How do ESCC 3201 and MIL-STD-981 really compare when it comes to space-grade inductors?
In space applications, component qualification is far more than a formality. Behind each standard lies a distinct philosophy in terms of testing severity, environmental constraints and long-term reliability.
Our latest white paper provides a clear and technical comparison of these two major qualification frameworks, based on real, space-qualified magnetic components such as:
- Chip inductors
- Low-profile inductors
- Common-mode chokes
A practical guide designed for engineers involved in satellite, launcher and deep-space programs, helping you make informed decisions for high-reliability designs.

What’s inside the white paper?
This document offers a detailed comparison between ESCC 3201 and MIL-STD-981, using Exxelia’s qualified MPCI, SESI, and CMC magnetic components as reference points. It examines areas where the standards converge, where they differ, and how optional testing can bridge the gap for missions requiring hybrid compliance.
Key topics covered include:
- The qualification flow and shared test philosophies across both standards
- Differences in burn-in duration, vibration levels, mechanical shock, and environmental stress
- ESCC-specific screenings such as barometric pressure and moisture resistance tests
- MIL-STD-981 requirements that can be added upon request, including radiography and DPA
- Guidance to help design engineers align component selection with mission requirements
- Which qualification tests are equivalent between ESCC and MIL standards
- Where the main differences lie (burn-in duration, vibration levels, environmental testing…)
- Why ESCC qualification often goes further on environmental robustness
- How ESCC-qualified inductors can be adapted to MIL-STD-981 requirements through optional screenings
The goal is to offer a clear and structured overview that simplifies decision-making for satellite, launcher, and deep-space applications.
Why this matters
Selecting the right qualification framework is essential to ensuring reliability, mission autonomy, and long-term performance. This white paper provides useful insights for teams who want a deeper understanding of how ESCC and MIL-STD requirements apply to magnetic components, and how Exxelia can support programs needing tailored screening or additional testing.
