Substitute Part Grouping Explanation

The MOC3083TVM qualifies as a direct substitute for the MOC3083TM based on electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Isolation voltage: 4170Vrms (identical)
• Off-state voltage: 800 V (identical)
• Static dV/dt rating: 600V/µs (identical)
• LED trigger current: 5mA maximum (identical)
• Hold current: 500µA typical (identical)
• Forward voltage: 1.3V typical (identical)
• Maximum forward current: 60 mA (identical)
• Operating temperature range: -40°C ~ 85°C (identical)
• Package configuration: 6-DIP through-hole (identical)
• Output type: Triac (identical)
• Zero-crossing circuit: Present (identical)
• Channel count: 1 (identical)

The MOC3083TVM maintains full electrical and mechanical compatibility with the MOC3083TM, differing only in product status and packaging format.
