Hearing from our supply chain that the larger passive case sizes are becoming increasingly difficult to source by virtue of the law of supply and demand driven by smaller form factor high-tech consumer electronics in particular. Certainly we are being told that availability of values ≤1uF & ≥0603 case size MLCCs are becoming a serious issue, which has a ring of truth.

Consideration is being given to fitting some 0402 where appropriate on to existing designs with only 0603 lands, to save mass PCB design changes. Whilst not ideal this might be a short-term solution with suitably limited implementation, but I can think of several downsides to this. 

I just wondered if others were being told the same from their purchasing/supply chain and whether a similar approach was being/already had been considered and/or implemented and/or refused and rejected

Thanks...
