Substitute Part Grouping Explanation

Substitution of the OP265AB is determined by strict equivalence across the following electrical and mechanical parameters:

• Wavelength: 850nm (exact match required)
• Maximum forward current: 50mA (exact match required)
• Typical forward voltage: 1.8V (exact match required)
• Radiant intensity: 7.5mW/cm² @ 20mA (exact match required)
• Viewing angle: 18° (exact match required)
• Operating temperature range: -40°C ~ 100°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)

The OP265FAB meets all substitution criteria as a direct equivalent, maintaining identical electrical performance and mechanical compatibility with the obsolete OP265AB.
