Substitute Part Grouping Explanation

Substitution eligibility for the OPB701AL is determined by strict equivalence across the following critical parameters:

• Sensing distance: 0.200" (5.08mm)
• Sensing method: Reflective
• Output type: Photodarlington
• Voltage rating: 15 V maximum collector-emitter breakdown
• Current rating: 100 mA maximum DC forward current
• Mounting configuration: Chassis mount
• Package format: Module, pre-wired
• Temperature operating range: -40°C to 100°C

The OPB701ALZ qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The OPB701ALZ is the direct equivalent substitute for the OPB701AL. Both components share identical electrical specifications, sensing characteristics, and mechanical form factors. The OPB701ALZ offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the OPB701ALZ meets ROHS3 compliance requirements, whereas the OPB701AL is non-compliant. For new designs and legacy system replacements, the OPB701ALZ is the appropriate selection based on regulatory compliance and product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can the OPB701ALZ directly replace the OPB701AL in existing applications?
