OPB773N Equivalent & Substitute Parts

Part Overview

The OPB773N is a reflective optical sensor manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This component functions as an infrared reflective sensor with NPN open collector output, designed for detecting Kodak® paper at sensing distances between 0.080" and 0.220" (2.03mm to 5.59mm). The OPB773N is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPB773N is determined by strict equivalence across the following critical parameters:

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

The OPB773TZ meets all electrical and functional parameters required for direct substitution. The primary distinction between the OPB773N and OPB773TZ is product status and compliance certification, with OPB773TZ being an active product with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The OPB773TZ is the direct equivalent for the obsolete OPB773N. Both components share identical electrical specifications, sensing characteristics, and functional performance. The OPB773TZ is the recommended selection for new designs and production applications due to its active product status and ROHS3 compliance certification. The OPB773N should be replaced with OPB773TZ in applications where regulatory compliance and long-term component availability are required.

Frequently Asked Questions (FAQ)

Q: Can OPB773TZ directly replace OPB773N in existing designs? A: Yes. The OPB773TZ provides electrical and functional equivalence across all specified parameters, including sensing distance, output configuration, supply voltage, and supply current.

Q: What is the primary difference between OPB773N and OPB773TZ? A: The OPB773N is obsolete and RoHS non-compliant, while the OPB773TZ is an active product with ROHS3 compliance. Both components are electrically and functionally identical.

Q: Are there any mounting differences between these parts? A: The OPB773N uses through-hole mounting, while the OPB773TZ uses chassis mount configuration. Physical mounting requirements should be evaluated during design integration.

Q: What certifications apply to the OPB773TZ? A: The OPB773TZ is ROHS3 compliant and REACH unaffected. Both components carry the same ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Is the OPB773TZ available in the same packaging as the OPB773N? A: Both components are supplied in module packaging. The OPB773TZ is available in bulk packaging format.
