Procurement Notes

This component is officially discontinued and no longer in active production by the manufacturer. Availability is restricted to existing stock held by distributors or secondary market suppliers such as Rochester Electronics. Verification of part authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the specific revision level and ensure compliance with current supply chain security requirements before acquisition.

Selection Notes

Engineers replacing this obsolete part must evaluate alternative SCR modules with comparable voltage and current ratings. The TO-200AA footprint compatibility should be verified against new candidates to maintain existing mechanical designs. Thermal resistance characteristics and gate triggering requirements must match the original system constraints. Cross-referencing datasheets for equivalent Infineon series or competing manufacturers is necessary to ensure functional parity in high-power applications.
