Substitute Part Grouping Explanation

Substitution of the OPB667T 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 inverted logic
• Mounting Type: Through-hole PCB mount
• Electrical Specifications: 4.5V to 16V supply voltage, 12 mA supply current, 30ns response time
• Operating Temperature Range: -40°C to 100°C
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The OPB667N qualifies as a direct substitute based on identical electrical characteristics, sensing method, and mechanical mounting requirements. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The OPB667N is the manufacturer-recommended substitute for the obsolete OPB667T. Both components maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs. The OPB667N carries active product status, providing assured availability and ongoing manufacturer support. Both parts satisfy ROHS3 compliance and REACH requirements, supporting regulatory obligations in current manufacturing environments. Selection between these parts should be based on packaging requirements and supply chain availability, as the OPB667N is supplied in tube packaging format.
