Parameter Comparison

Engineering Selection Recommendations

The OPB718Z is the direct substitute for the OPB718. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in reflective optical sensing applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The OPB718 is obsolete, while the OPB718Z maintains active product status. Additionally, the OPB718Z achieves ROHS3 compliance, whereas the OPB718 is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the OPB718Z is the appropriate selection. For legacy system maintenance where component specifications are the sole requirement, either part satisfies the functional requirements.
