Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPB770T is determined by strict equivalence across the following critical parameters:

• Sensing Method: Reflective
• Sensing Distance: 0.080" ~ 0.220" (2.03mm ~ 5.59mm)
• Sensing Object: Kodak® Paper
• Output Configuration: Totem Pole
• Sensing Light: Infrared
• Current - Supply: 10 mA
• Voltage - Supply: 4.75V ~ 5.25V
• Package / Case: Module

The OPB770TZ qualifies as a direct substitute based on complete alignment with all electrical and functional parameters. The primary distinction is product status: OPB770TZ is active and RoHS3 compliant, whereas OPB770T is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The OPB770TZ is the direct substitute for OPB770T applications. Both components share identical electrical specifications, sensing characteristics, and functional parameters. The OPB770TZ offers two significant advantages: active product status ensures ongoing availability and manufacturer support, and ROHS3 compliance satisfies current regulatory requirements for new designs and manufacturing environments where RoHS compliance is mandated.

For systems currently using OPB770T, transition to OPB770TZ maintains full functional compatibility while addressing obsolescence and compliance concerns. The base product number OPB770 is common to both variants, confirming their interchangeability at the functional level.

Frequently Asked Questions (FAQ)

Q: Can OPB770TZ directly replace OPB770T in existing designs?

A: Yes. Both components share identical sensing distance (0.080" ~ 0.220"), output configuration (Totem Pole), supply current (10 mA), supply voltage (4.75V ~ 5.25V), and sensing method (reflective infrared). Electrical and mechanical compatibility is complete.

Q: What is the difference between OPB770T and OPB770TZ?

A: The primary differences are product status and RoHS compliance. OPB770T is obsolete and RoHS non-compliant. OPB770TZ is active and ROHS3 compliant. All functional and electrical parameters are identical.

Q: Why is OPB770T obsolete?

A: OPB770T has been discontinued by the manufacturer. OPB770TZ is the active equivalent and recommended for all new applications and replacements.

Q: Are there packaging differences between OPB770T and OPB770TZ?

A: OPB770T packaging is listed as unspecified. OPB770TZ is supplied in Bag packaging. Both are Module package types with identical electrical characteristics.

Q: What compliance certifications apply to OPB770TZ?

A: OPB770TZ is ROHS3 compliant and REACH unaffected. It carries ECCN classification EAR99 and HTSUS code 8541.49.8000.
