Force Tech Talk #14 – Form-Fit-Function (FFF)

31 July 2025

Show Notes

In this episode of Force Tech Talk, Charlotte and Ben sit down to demystify a topic we’re asked about time and time again: what does Form-Fit-Function (FFF) actually mean when it comes to obsolete semiconductors?

From defining each element of FFF to understanding why it matters so much, especially in aerospace and defence, we explore how legacy systems are supported long after parts go end-of-life. We unpack key considerations like packaging differences, die revisions, and the challenges of verifying compliance without original documentation.

We also discuss how Force Technologies ensures that replacement components meet strict FFF standards, covering everything from engineering analysis and comparative testing, to real-world customer collaboration and application-level validation.

If you’re managing long-life systems, sourcing obsolete parts, or simply curious about the technical and commercial impacts of component replacement, this conversation is full of practical insights.
