Substitute Part Grouping Explanation

The OPB696AZ qualifies as a direct substitute for the OPB696A based on the following critical parameters that determine functional equivalence:

• Sensing Method: Both components utilize optical flag sensing technology
• Output Configuration: Both feature NPN open collector buffer output
• Mounting Type: Both employ snap-in mounting
• Voltage Supply Range: Both operate within 4.5V ~ 8V
• Current Supply: Both require 20 mA
• Response Time: Both maintain 30ns response time
• Package / Case: Both are module connectors
• Series: Both belong to the Photologic® series
• Manufacturer: Both manufactured by TT Electronics/Optek Technology

The primary distinction between these parts is product status and compliance certification, with OPB696AZ representing the active production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OPB696AZ is the direct active production equivalent of the obsolete OPB696A. All electrical and mechanical parameters are identical, ensuring functional compatibility in existing circuit designs and mechanical assemblies.

The OPB696AZ offers improved compliance status, achieving ROHS3 compliance compared to the non-compliant RoHS status of the OPB696A. Both components maintain identical REACH and ECCN classifications. The transition from OPB696A to OPB696AZ does not introduce compatibility constraints for applications requiring the specified electrical characteristics and snap-in mounting configuration.
