Alternative components sourcing for cross-refs and drop-in candidates
When the preferred MPN is scarce, you need alternates that engineering can approve—and a partner who can actually buy them.
The problem
Cross-reference tables look neat until voltage, package, firmware, and second-source reality intervene. Teams stall between engineering approval and procurement execution.
