How has the recent supply chain volatility changed your component selection criteria?

Hi everyone,

I’ve been re-evaluating my hardware design process lately, and I’ve realized that my approach to component selection has shifted significantly. I wanted to open this up for discussion and see how your strategies have evolved.

A few years ago, my "core logic" for selection was straightforward: Best Performance > Best Price > Brand Reputation. If the datasheet showed the right curves and the price was competitive, I’d lock the part into my schematic without a second thought.

However, after dealing with repeated supply chain disruptions, unexpected delivery delays, and sudden "End-of-Life" (EOL) announcements, my criteria have shifted heavily toward robustness and reliability. I now prioritize these factors, sometimes even at the cost of peak performance:

• Availability over Price: Even if a chip offers superior performance, if its supply chain is unstable or it relies on a single source, I now tend to pass. I prioritize parts with multiple distribution channels and long-term stock availability across major platforms.
• Footprint Compatibility: In my PCB layouts, I now prioritize designs that are footprint-compatible with multiple manufacturers. Even if I’m using "Brand A" now, I make sure the layout allows me to switch to "Brand B" quickly if shortages hit, without having to redesign the board.
• Pre-validated Alternatives: During the early design phase, I now proactively identify and cross-reference alternative parts. I try to verify the secondary options during the simulation phase to ensure I’m not caught off guard.

I’m curious to hear your thoughts:

1. Have you experienced this same shift in your design philosophy?
2. How do you balance potential performance trade-offs when prioritizing availability and supply chain security?
3. For projects that must use "niche" or highly specific components, what are your best practices for risk mitigation?

Looking forward to hearing your insights and experiences!
