Engineering Selection Recommendations

For new designs and procurement, OPB892T55Z is the primary recommended substitute. This part maintains active product status with full manufacturer support and carries identical electrical and environmental specifications to the obsolete OPB892L55Z. Both parts share the OPB892 base product number, ensuring design compatibility.

For applications requiring alternative base product numbers within the OPB series, OPB890 and OPB891 variants provide parametric equivalence. All active alternatives listed—OPB890L11Z, OPB890T11Z, OPB890T51Z, OPB890T55Z, OPB891T51Z, OPB891T55Z, and OPB892L51Z—maintain identical electrical ratings, operating temperature range, and compliance certifications.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Moisture sensitivity level remains constant at MSL 1 (Unlimited) across all alternatives, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can OPB892T55Z directly replace OPB892L55Z in existing designs?

A: Yes. OPB892T55Z is the direct active equivalent. Both parts share identical electrical specifications (50 mA If max, 30 mA Ic max, 30 V VCE breakdown), operating temperature range (-40°C ~ 85°C), sensing distance (0.125"), sensing method (through-beam), output configuration (phototransistor), and mounting configuration (PCB mount, chassis mount). The only difference is product status: OPB892L55Z is obsolete while OPB892T55Z is active.

Q: What is the difference between OPB890 and OPB891 series alternatives?

A: OPB890 and OPB891 are alternative base product numbers within the same optical sensor family. All variants listed—OPB890L11Z, OPB890T11Z, OPB890T51Z, OPB890T55Z, OPB891T51Z, and OPB891T55Z—maintain identical electrical and mechanical parameters to OPB892L55Z. Selection among these alternatives is based on availability and packaging preferences, as all meet the same functional requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance and REACH unaffected status, matching the regulatory certifications of OPB892L55Z.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Standard PCB assembly processes and storage conditions are acceptable without special moisture control measures.

Q: Can I use OPB892L51Z as a substitute?

A: Yes. OPB892L51Z is parametrically equivalent and carries active product status. It maintains all electrical specifications and environmental ratings of OPB892L55Z while offering improved availability.

Q: Why are there multiple part numbers with identical specifications?

A: The OPB series includes multiple variants within the same product family. Variations in the part number suffix (such as L/T designations and numeric codes) reflect manufacturing or packaging differences that do not affect the electrical or mechanical parameters relevant to substitution. All listed alternatives are functionally interchangeable based on the provided specifications.
