Not taking care of issues in your BOM will ruin your hardware project when it’s time to order—full stop. In this video I walk through how I use Altium Develop (the BOM manager / Materials Manager) to surface the exact problems that bite teams in production: parts that are “not recommended for new designs,” parts that look active but have zero authorized distributors, unknown data, end-of-life flags, and supply chain risk like sourcing time overshoot. The demo is on the NVIDIA Jetson AGX Orin carrier board BOM, and I show you how a senior hardware engineer actually thinks when a part needs to be replaced. I’m doing real parametric search and alternate-part selection, not just clicking random substitutions. I’ll pop a questionable MPN into Octopart to sanity-check distributor coverage, then I’ll filter for stuff I actually care about—active product status, RoHS/REACH compliance, voltage, capacitance, tolerance, temperature range, and availability—then replace the line item and watch the error disappear. I also call out a big workflow mistake: don’t get bogged down in a sea of alternates with the same issues. You only need one solid primary and one solid alternate to build a BOM you can actually manufacture again later.
