Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection among equivalent parts should be based on inventory availability and application-specific requirements. OPB960T51 offers the highest inventory level at 20199 units. OPB960N51 provides 8810 units with identical electrical and mechanical specifications. Parts designated with the OPB970 base number represent alternative configurations within the Photologic® series that maintain all critical sensing parameters. All parts are suitable for direct substitution in through-beam optical sensing applications requiring 0.125" sensing distance and 5V supply operation.

Frequently Asked Questions (FAQ)

Q: Can OPB960N11 be directly replaced with OPB960T51? A: Yes. Both parts share identical sensing distance (0.125"), output configuration (totem pole buffer), supply voltage (4.75V ~ 5.25V), current draw (15 mA), response time (70ns), operating temperature range (-40°C ~ 70°C), and PCB mount package type. Direct substitution is functionally equivalent.

Q: What is the difference between OPB960 and OPB970 base series parts? A: Both series maintain identical electrical and mechanical parameters specified for through-beam sensing at 0.125" distance. Differences in base product numbering reflect internal design variations that do not affect functional performance in equivalent applications.
