Key Parameters

Substitute Part Grouping Explanation

Substitution for the OPB773NZ is determined by strict equivalence across the following critical parameters:

• Sensing method (Reflective)
• Sensing distance range (0.080" ~ 0.220" / 2.03mm ~ 5.59mm)
• Sensing object (Kodak® Paper)
• Output configuration (NPN - Open Collector/Dark-ON)
• Sensing light type (Infrared)
• Mounting type (Chassis Mount)
• Supply voltage range (4.75V ~ 5.25V)
• Supply current (10 mA)
• Package type (Module)

The OPB773TZ qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status: OPB773TZ is active, whereas OPB773NZ is obsolete.
