Substitute Part Grouping Explanation

Substitution of the OP265AA is determined by strict equivalence across the following critical parameters:

• Wavelength: 850nm (exact match required)
• Current Rating: 50mA maximum forward current
• Voltage: 1.8V typical forward voltage
• Radiant Intensity: 5.5mW/cm² @ 20mA minimum
• Viewing Angle: 18°
• Mounting Type: Through Hole
• Package Type: Radial

The OP265FAA meets all specified electrical and mechanical parameters and qualifies as a direct substitute. Both components share identical functional characteristics within the defined operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The OP265FAA is the qualified substitute for the obsolete OP265AA. Both components are manufactured by TT Electronics/Optek Technology and maintain identical electrical and mechanical specifications across all critical parameters.

The OP265FAA carries Active product status, ensuring ongoing availability and supply chain continuity. The substitute component is ROHS3 compliant, meeting current environmental and regulatory requirements. Both components share REACH Unaffected status and EAR99 ECCN classification.

Selection of the OP265FAA eliminates obsolescence risk while maintaining full functional equivalence in circuit applications designed for the OP265AA.
