Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPB770N is determined by strict alignment of the following critical parameters:

• Sensing Distance: 0.080" ~ 0.220" (2.03mm ~ 5.59mm)
• Sensing Method: Reflective
• 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 meets all specified electrical and mechanical parameters required for direct substitution with the OPB770N. Both components share identical sensing characteristics, supply requirements, and functional output configuration.

Parameter Comparison

Engineering Selection Recommendations

The OPB770TZ is the direct substitute for the OPB770N. Both components are manufactured by the same supplier and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: the OPB770N is obsolete while the OPB770TZ remains in active production.

For new designs or system replacements, the OPB770TZ is the appropriate selection. The OPB770TZ provides improved regulatory compliance, meeting ROHS3 standards compared to the non-compliant status of the OPB770N. Both components maintain REACH Unaffected status and identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the OPB770TZ directly replace the OPB770N in existing applications?

A: Yes. The OPB770TZ meets all electrical and mechanical specifications of the OPB770N, including sensing distance, output configuration, supply voltage, and current requirements. No circuit modifications are required.

Q: What is the difference between the OPB770N and OPB770TZ?

A: The components are functionally identical. The OPB770TZ is the active production variant with ROHS3 compliance, while the OPB770N is obsolete and RoHS non-compliant. Packaging differs: OPB770N uses module packaging while OPB770TZ is supplied in bag packaging.

Q: Are there any compliance considerations when switching from OPB770N to OPB770TZ?

A: The OPB770TZ provides improved regulatory compliance with ROHS3 certification. Both components maintain REACH Unaffected status. If your application requires RoHS compliance, the OPB770TZ is the appropriate choice.

Q: What is the sensing distance specification for these optical sensors?

A: Both the OPB770N and OPB770TZ operate with a sensing distance of 0.080" to 0.220" (2.03mm to 5.59mm) for Kodak® Paper detection using reflective infrared sensing.

Q: Are mounting considerations different between these parts?

A: The OPB770N specifies through hole mounting. The OPB770TZ mounting type is not specified in available documentation. Verify mechanical compatibility with your application before implementation.
