Institutional Risk Assessment: 1756-EN2T
Statistical failure modeling indicates that Allen-Bradley ControlLogix modules of this vintage exhibit a MTBF (Mean Time Between Failure) degradation of 12% annually after the 10-year service mark. Given this unit was discontinued in 2023, it has exceeded its primary reliability window.
The $2,800 - $4,200 replacement cost represents only 5% of the total economic exposure. A single failure event triggers an immediate $12,500/hr cascade loss across interconnected facility sub-networks.
Lifecycle Termination & Acquisition Protocol
As of CURRENT_TIMESTAMP, the 1756-EN2T is classified as "High Scarcity" (Stage 4 Obsolescence). Secondary markets show a 45-day rolling average for verified functioning units. Acquisition should be prioritized for units with confirmed firmware revision matching your existingControlLogix architecture to avoid mid-stream protocol mismatch.
Industrial Ghost Parts protocols suggest immediate acquisition of cold-standby units to mitigate on-going supply chain volatility in the Allen-Bradley lifecycle.

Expert Recommendation
Given the $2,800 - $4,200 replacement cost and $12,500/hr downtime impact, we recommend maintaining a minimum of 2 verified units in local on-site storage.
