OPL810-OC Equivalent & Substitute Parts
Part Overview
The OPL810-OC is a Photologic® optical sensor manufactured by TT Electronics/Optek Technology, designed as a 935nm photo detector with logic output in an open collector configuration housed in a TO-18 small package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The OPL810-OC operates across an extended temperature range of -55°C to 105°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Engineering Selection Recommendations
OPL800-OC is the primary substitute for the obsolete OPL810-OC. Both components share identical wavelength, sensor type, package configuration, and compliance certifications. The OPL800-OC maintains active product status with extended operating temperature capability (-55°C to 110°C versus -55°C to 105°C), providing improved thermal margin. Output configuration is functionally equivalent (Open Collector), making this a direct replacement without circuit modification requirements.
OPL813-OC serves as an alternative substitute when output inversion is required by system design. This component is also active and maintains all core compliance and packaging specifications. The critical distinction is the Open Collector Inverter output type, which inverts the logic signal compared to the OPL810-OC. Selection of the OPL813-OC requires verification that the receiving circuit accommodates inverted logic levels.
Both substitute parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original OPL810-OC specification.
Frequently Asked Questions (FAQ)
Q: Can the OPL800-OC directly replace the OPL810-OC without circuit modifications?
A: Yes. The OPL800-OC shares identical wavelength (935nm), sensor type (Photo Detector, Logic Output), output configuration (Open Collector), and package (TO-18 small). No circuit modifications are required for functional substitution.
Q: What is the key difference between OPL800-OC and OPL813-OC?
A: The output type differs. OPL800-OC provides standard Open Collector output, while OPL813-OC provides Open Collector Inverter output. The OPL813-OC inverts the logic signal, requiring circuit-level verification before implementation.
Q: Are both substitute parts currently available?
A: Yes. OPL800-OC is active with 1176 pieces in stock. OPL813-OC is active with 621 pieces in stock. The original OPL810-OC is obsolete.
Q: Do the substitute parts meet the same compliance requirements?
A: Yes. Both OPL800-OC and OPL813-OC are ROHS3 compliant with REACH Unaffected status, matching the OPL810-OC specification.
Q: What is the operating temperature difference between OPL810-OC and OPL800-OC?
A: OPL810-OC operates from -55°C to 105°C. OPL800-OC extends the upper limit to 110°C, providing 5°C additional thermal margin.
Q: Are all three parts housed in the same package?
A: Yes. OPL810-OC, OPL800-OC, and OPL813-OC all use TO-18 small package configuration, ensuring mechanical compatibility in existing PCB layouts.
