Engineering Selection Recommendations
All listed substitute parts maintain full compliance with ROHS3 and REACH requirements, matching the regulatory status of the OPB970P55. The primary distinction between substitute options is product status: all alternatives are classified as active, ensuring continued manufacturer support and supply chain availability.
For new designs and production continuity, selection should prioritize parts with the highest inventory levels and confirmed active status. OPB960T51 offers the largest available inventory (20,199 pcs), followed by OPB960N51 (8,810 pcs). Both maintain identical electrical and mechanical specifications to the OPB970P55.
Packaging type differences (bulk vs. standard) do not affect functional performance or circuit-level compatibility. Selection between OPB930 and OPB960 base families is determined by application-specific requirements not specified in the provided parameters; both families are electrically and mechanically equivalent for through-beam 0.125" sensing applications.
Frequently Asked Questions (FAQ)
Q: Can OPB960 series parts directly replace OPB970P55 in existing designs?
A: Yes. OPB960 series optical sensors maintain identical electrical specifications (4.75V ~ 5.25V supply, 15 mA current, 70ns response time), mechanical mounting (through hole PCB mount), and sensing characteristics (0.125" through-beam) as the OPB970P55. Direct substitution is functionally equivalent.
Q: What is the difference between OPB930 and OPB960 base product families?
A: Both families provide identical electrical and mechanical performance for 0.125" through-beam PCB mount applications. Differences are limited to internal design variants not specified in the provided parameters. Selection between families should be based on application-specific requirements and inventory availability.
Q: Does packaging type (bulk vs. standard) affect electrical performance?
A: No. Packaging type differences do not alter electrical characteristics, response time, supply voltage requirements, or operating temperature range. Packaging affects only handling, storage, and procurement logistics.
Q: Why is OPB970P55 classified as obsolete?
A: The OPB970P55 has reached end-of-life status. Active alternatives within the Photologic® family provide equivalent functionality with ongoing manufacturer support and confirmed supply availability.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the OPB970P55.
Q: Which substitute part offers the best inventory availability?
A: OPB960T51 provides the highest inventory level at 20,199 pcs, followed by OPB960N51 at 8,810 pcs. Both maintain full electrical and mechanical equivalence to the OPB970P55.
