Substitute Part Grouping Explanation

Substitute parts for the OPB771NZ are identified based on electrical and mechanical parameter equivalence. The following parameters determine substitution compatibility:

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

Parts meeting all these criteria are classified as direct substitutes and can replace the OPB771NZ in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The OPB771TZ is the manufacturer-recommended substitute for the OPB771NZ. Both parts share identical electrical and mechanical specifications, including sensing distance, output configuration, supply voltage, and current requirements. The primary distinction is product status: the OPB771NZ is obsolete while the OPB771TZ remains active.

The OPB771TZ maintains full ROHS3 compliance and REACH unaffected status, consistent with the original part. Selection of the OPB771TZ ensures continued access to an equivalent optical sensor within the Photologic® series from TT Electronics/Optek Technology.

Frequently Asked Questions (FAQ)

Q: Can the OPB771TZ directly replace the OPB771NZ?

A: Yes. The OPB771TZ is the manufacturer-recommended substitute. Both parts have identical electrical specifications (4.75V ~ 5.25V supply, 10 mA current), sensing distance (0.080" ~ 0.220"), output configuration (NPN - Open Collector), and mounting type (Chassis Mount Module).
