100324/VYA

Overview

Procurement Notes

This component is distributed by Rochester Electronics, LLC, a specialist in the secondary market for obsolete and end-of-life integrated circuits. Procurement verification must focus on confirming the specific manufacturer lot code, date code, and authenticity of the source device. Buyers should request detailed traceability documentation and test reports to ensure the part meets original equipment manufacturer specifications before integration into production or maintenance workflows.

Selection Notes

Selection of this part requires confirmation that the original manufacturer has discontinued active production. Engineers must verify pin compatibility and electrical parameter equivalence against current available alternatives if redesign is an option. Due to the secondary market nature, lead times may vary significantly. It is critical to validate the package type and marking codes to distinguish between different manufacturing lots or potential re-marked units during the sourcing phase.

Part Context
