Selection between these families should be based on existing design documentation and supply chain preferences, as all maintain identical electrical and mechanical specifications.
Frequently Asked Questions (FAQ)
Q: Can OPB960 series parts directly replace OPB930 series parts in the same application?
A: Yes. Both OPB930 and OPB960 series parts maintain identical electrical specifications (voltage, current, response time, operating temperature) and mechanical parameters (sensing distance, mounting type, package configuration). Substitution is functionally equivalent.
Q: What is the difference between the suffix codes (L51, L55, N11, N51, N55, P51, T11, T51, T55) in the part numbers?
A: The suffix codes represent internal design variants within the Photologic® series. All variants listed maintain identical electrical and mechanical parameters specified for this application. Suffix differences do not affect functional substitution capability.
Q: Why is OPB970L55 classified as obsolete?
A: The OPB970L55 has been superseded by active alternatives within the Photologic® family. The OPB930 and OPB960 series provide equivalent functionality with continued manufacturer support and availability.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.
Q: Which substitute part should be selected for new designs?
A: For new designs, select from Active products with the highest inventory availability. OPB960T51 offers the largest stock position. Consult design documentation for any existing part number preferences within the OPB930 or OPB960 families.
Q: Is PCB layout modification required when substituting these parts?
A: No. All substitute parts maintain identical through-hole mounting specifications and PCB mount package configuration, requiring no layout changes.
