Key Parameters

Substitute Part Grouping Explanation

Substitution of the NCP1217P65 is determined by strict equivalence across the following critical parameters:

• Topology & Isolation: Flyback converter with isolated output
• Electrical Specifications: Supply voltage range (7.6V ~ 16V), startup voltage (12.8V), switching frequency (65kHz), and duty cycle (74%)
• Protection Features: Over-load, over-temperature, and short-circuit fault protection
• Thermal Range: Operating temperature 0°C ~ 150°C (TJ)
• Package Compatibility: 8-DIP (0.300", 7.62mm) with 7 leads, through-hole mounting
• Moisture Sensitivity: MSL 1 (Unlimited)

The NCP1217P65G qualifies as a direct substitute based on identical electrical and mechanical specifications within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The NCP1217P65G is the direct equivalent substitute for the NCP1217P65. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in flyback converter applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The NCP1217P65 is obsolete, while the NCP1217P65G maintains active production status. Additionally, the NCP1217P65G meets ROHS3 compliance requirements, whereas the original NCP1217P65 is non-compliant. For new designs and production continuity, the NCP1217P65G is the appropriate selection.

Both components maintain identical supply voltage ranges, switching frequency, duty cycle, fault protection mechanisms, and thermal operating specifications. No circuit redesign or board layout modification is required when transitioning from NCP1217P65 to NCP1217P65G.
