Substitute Part Grouping Explanation

Substitution of the OPB732W is determined by strict equivalence across the following critical parameters:

• Sensing distance: 3" (76.2mm)
• Sensing method: Reflective
• Output type: Phototransistor
• Voltage rating: 30 V maximum collector-emitter breakdown
• Current ratings: 50 mA maximum collector current and 50 mA maximum DC forward current
• Mounting configuration: Chassis mount
• Package type: Module, pre-wired

The OPB732WZ qualifies as a direct substitute based on identical electrical specifications, sensing characteristics, and mechanical form factor. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The OPB732WZ is the direct equivalent substitute for the obsolete OPB732W. Both components share identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs. The OPB732WZ offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the OPB732WZ meets ROHS3 compliance requirements, whereas the OPB732W is non-compliant. For new designs and legacy system replacements, the OPB732WZ is the appropriate selection. The packaging difference (bulk for OPB732WZ versus standard for OPB732W) does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the OPB732WZ directly replace the OPB732W in existing applications?

A: Yes. The OPB732WZ is electrically and mechanically identical to the OPB732W. All electrical parameters, sensing characteristics, and mounting specifications are equivalent, enabling direct substitution without circuit modification.

Q: What is the primary reason to transition from OPB732W to OPB732WZ?

A: The OPB732W is classified as obsolete, creating supply and support risks. The OPB732WZ maintains active product status with higher inventory availability, ensuring long-term component sourcing for production and maintenance.

Q: Does the packaging difference between OPB732W and OPB732WZ affect performance?

A: No. The packaging difference (bulk versus standard) is a distribution and handling consideration only. The electrical and mechanical form factor remain identical, with no impact on circuit performance or integration.

Q: Are there compliance differences between these parts?

A: Yes. The OPB732WZ is ROHS3 compliant, while the OPB732W is non-compliant. For applications subject to RoHS regulations, the OPB732WZ is the required selection.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by sensing distance (3" / 76.2mm), sensing method (reflective), output type (phototransistor), voltage rating (30 V maximum), current ratings (50 mA maximum), and mounting configuration (chassis mount, pre-wired module).
