Substitute Part Grouping Explanation

Substitution of the OPB705W optical sensor is determined by strict equivalence across the following critical parameters:

• Sensing Distance: 0.150" (3.81mm) — determines detection range and application compatibility
• Sensing Method: Reflective — defines the operational principle and target surface requirements
• Output Type: Phototransistor — specifies the signal interface and circuit integration method
• Electrical Ratings: Voltage (30 V max), Collector Current (25 mA max), Forward Current (40 mA max) — ensure safe operation within system constraints
• Mounting Configuration: Chassis Mount, Module, Pre-Wired — confirms mechanical and electrical integration compatibility

The OPB705WZ maintains identical electrical and functional specifications across all critical parameters, establishing it as a direct substitute for the obsolete OPB705W.

Frequently Asked Questions (FAQ)

Q: Can the OPB705WZ be used as a direct replacement for the OPB705W?

A: Yes. The OPB705WZ is electrically and mechanically equivalent to the OPB705W. Both components share identical sensing distance (0.150"), sensing method (reflective), output type (phototransistor), electrical ratings, and mounting configuration. The OPB705WZ is the active production equivalent of the obsolete OPB705W.

Q: What is the difference between the OPB705W and OPB705WZ?

A: The primary differences are product status and regulatory compliance. The OPB705W is obsolete and RoHS non-compliant, while the OPB705WZ is in active production and ROHS3 compliant. All functional and electrical specifications are identical.

Q: Are there any compatibility concerns when substituting the OPB705WZ for the OPB705W?

A: No compatibility concerns exist. The OPB705WZ maintains the same chassis-mount configuration, pre-wired module package, and electrical characteristics. Circuit integration and mechanical installation procedures remain unchanged.

Q: What is the sensing distance of these optical sensors?

A: Both the OPB705W and OPB705WZ operate at a sensing distance of 0.150" (3.81mm) in reflective mode, detecting objects at this fixed distance from the sensor module.

Q: What is the maximum collector current rating?

A: The maximum collector current (Ic) for both components is 25 mA. Circuit designs must not exceed this rating during operation.
