OPB696B Optical Sensor Module Equivalent and Substitute Parts

Part Overview

The OPB696B is an optical flag module with connector manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This component is classified as an optical sensor with NPN open collector buffer output configuration and snap-in mounting. The OPB696B is currently obsolete, necessitating identification of active equivalent components to maintain system functionality and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

The OPB696B has one manufacturer-recommended substitute: OPB696AZ. Substitution eligibility is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Output Configuration: NPN - Open Collector, Buffer (identical)
• Current - Supply: 20 mA (identical)
• Response Time: 30ns (identical)

Mechanical Compatibility Parameters:

• Mounting Type: Snap-In (identical)
• Package / Case: Module, Connector (identical)
• Sensing Method: Optical Flag (identical)

Voltage Supply Consideration: The OPB696B operates at 8V ~ 13.5V, while the OPB696AZ operates at 4.5V ~ 8V. The overlap range is 8V, which permits operation within this common window. Applications requiring the full 8V ~ 13.5V range of the OPB696B must verify that system voltage does not exceed 8V when using the OPB696AZ.

Parameter Comparison

Engineering Selection Recommendations

The OPB696AZ is the manufacturer-recommended substitute for the obsolete OPB696B. Both components share identical electrical output characteristics (NPN open collector buffer), supply current (20 mA), response time (30ns), and mechanical mounting configuration (snap-in module with connector).

The OPB696AZ is currently in active production status, ensuring availability for new designs and ongoing production support. The OPB696AZ carries ROHS3 compliance certification, whereas the OPB696B is RoHS non-compliant. Both components maintain identical REACH and ECCN classifications.

The primary design consideration is voltage supply range. The OPB696AZ operates within 4.5V ~ 8V, which overlaps with the OPB696B range of 8V ~ 13.5V at the 8V point. System designs operating exclusively within the 4.5V ~ 8V window are fully compatible with the OPB696AZ. Designs requiring operation above 8V require alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the OPB696AZ directly replace the OPB696B in all applications?

A: Direct replacement is possible only when system supply voltage does not exceed 8V. The OPB696AZ maximum supply voltage is 8V, while the OPB696B supports up to 13.5V. Electrical output characteristics, current draw, response time, and mechanical mounting are identical between both components.

Q: What is the voltage overlap range between OPB696B and OPB696AZ?

A: Both components operate at 8V. The OPB696B range is 8V ~ 13.5V, and the OPB696AZ range is 4.5V ~ 8V. Applications designed for 8V operation are compatible with both parts.

Q: Are there differences in connector or packaging between these components?

A: Both the OPB696B and OPB696AZ use identical package and case specifications: Module, Connector with snap-in mounting. No mechanical redesign is required for substitution within compatible voltage ranges.

Q: What compliance certifications differ between OPB696B and OPB696AZ?

A: The OPB696AZ is ROHS3 compliant, while the OPB696B is RoHS non-compliant. Both components are REACH Unaffected and carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Is the OPB696AZ available in the same packaging as the OPB696B?

A: The OPB696AZ is supplied in bulk packaging, while the OPB696B packaging specification is not detailed in the provided data. Both components use identical module and connector case specifications for functional compatibility.

Q: What operating temperature range does the OPB696AZ support?

A: The OPB696AZ operates across -40°C ~ 100°C. Operating temperature specification for the OPB696B is not provided in the available data.
