Substitute Part Grouping Explanation

Substitution of the OPB665T is determined by strict equivalence across the following critical parameters:

• Sensing Distance: 0.125" (3.18mm) through-beam configuration
• Output Configuration: Pull-Up Resistor with Buffer output
• Mounting Type: Through Hole PCB Mount
• Electrical Specifications: 4.5V ~ 16V supply voltage, 12 mA supply current, 30ns response time
• Operating Temperature Range: -40°C ~ 100°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The OPB665N is identified as a manufacturer-recommended substitute. Both components share identical electrical and mechanical specifications, with the primary distinction being product status and packaging configuration.

Parameter Comparison
