Telecom Procurement Notes

This component is officially listed as discontinued by Infineon Technologies. Availability is restricted, and it may not be sold in all regions through standard distributors. Verification of current stock status and end-of-life documentation is essential before design finalization. Sourcing should focus on authorized channels or approved secondary markets to ensure authenticity and traceability.

Telecom Selection Notes

Engineers replacing this part must evaluate pin-compatible alternatives within the same SOCRATES family or newer generations. Key parameters such as channel count, interface types, and operating voltage must match the original design requirements. Thermal management strategies should be reviewed, as power dissipation characteristics may vary between legacy and replacement components.

Telecom Part Context
