About The Obsolescence Brief
Every engineer has a version of the same story. A reorder bounces. The part is gone. Nobody got a notice. Now someone has to figure out what to do next, fast, with a product in production and a line waiting.
The Obsolescence Brief exists for the people who live in that problem.
This is a practitioner newsletter covering electronic component obsolescence, end-of-life risk, and the decisions that follow when a part you depend on disappears. Every issue includes a deep-dive teardown of a real obsolete part, a look at what the replacement landscape actually looks like, and the watch list items worth tracking before they become emergencies.
Who writes it
A supply chain professional with ten years of experience across healthcare, oil and gas, manufacturing, and defense contractor manufacturing. I have worked component obsolescence from the inside: the BOM scrubs, the last-time buys, the alternate qualification cycles, the moments when a cross-reference tool points you at a part that will not actually work in your design.
This newsletter is what I wanted to read and could not find. Most obsolescence content is vendor marketing dressed up as advice. The independent, practitioner-grade, vendor-neutral take does not exist in newsletter form. This is the attempt to fix that.
What you will find here
Every claim is sourced. Every suggested replacement is framed as a candidate to evaluate in your own system, not a guaranteed drop-in. The engineering judgment here comes from experience, not a spec sheet summary. When the honest answer is "there is no clean path," that is what you will read.
What you will not find here
Vendor promotion. Unverified statistics. Parts presented as drop-in replacements when they are not. Generic supply chain advice that applies to everything and helps nothing.
