The risk is not theoretical. Semiconductor manufacturers are already changing their product mix and manufacturing priorities as demand shifts toward higher-value AI and data-center products.
The Cost of One Missing Component
Samsung, for example, explicitly stated that its Memory Business was improving profitability by increasing sales of high-value-added products such as HBM, server DDR5, and enterprise SSDs. Samsung also said it planned to continue prioritizing high-value-added products for AI applications in 2026.
TSMC has also been shifting mature-node capacity toward higher-demand power-management applications. As AI infrastructure drives greater demand for PMICs and power devices, the company is reducing portions of its 8-inch capacity while prioritizing manufacturing resources toward products serving higher-value applications.
STMicroelectronics is increasingly emphasizing power semiconductor technologies designed for high-demand applications. Its portfolio includes GaN and SiC solutions targeting AI servers, industrial systems, and high-power infrastructure, reflecting a broader shift toward power devices capable of supporting higher power density and increasingly demanding electrical architectures.

These changes do not mean manufacturers are simply abandoning conventional components. Rather, they demonstrate how limited manufacturing capacity and capital are increasingly being directed toward products with stronger demand and higher value, particularly across AI and data-center markets.
For industrial manufacturers, that distinction matters.
A mature component can remain essential to a factory while becoming a lower strategic priority for its manufacturer. If production is reduced, a product family is rationalized, or allocation is redirected, a previously routine BOM item can suddenly become difficult to source
Three Defenses Against Component Discontinuation Risk
1. Conduct BOM Health Audits Regular BOM reviews can identify potential bottlenecks before they become emergencies. Manufacturers should prioritize:
（1）Single-source and EOL components （2）Legacy or mature-node semiconductors （3）Parts with unstable or extended lead times （4）Hard-to-substitute components （5）Parts dependent on a single manufacturer or factory （6）The goal is to identify which components could stop production if availability changes.
2. Pre-Qualify Drop-In Alternatives Finding a replacement after a component becomes unavailable is already too late.
Manufacturers should pre-qualify form-fit-function alternatives and verify electrical specifications, tolerance, temperature range, package, footprint, reliability, and certifications.
This ensures a replacement is ready before the original component becomes a constraint.
3. Secure Verified Buffer Stock Strategic inventory can protect critical components against sudden EOL announcements, allocation restrictions, and lead-time increases.
However, availability alone is not enough. Critical material should have appropriate traceability, authenticity, date-code, packaging, and quality verification.
