Parameter Comparison

Engineering Selection Recommendations

The OPB902W55 is obsolete and no longer in active production. Both OPB902W55Z and OPB912W55Z are active production parts that maintain full electrical and mechanical compatibility with the original specification.

OPB902W55Z is the direct equivalent, sharing the same base product number (OPB902) and offering ROHS3 compliance. This part is the primary substitute for direct replacement applications.

OPB912W55Z is the manufacturer-recommended alternative, utilizing the OPB912 base product number while maintaining identical electrical specifications and performance characteristics. This part is also ROHS3 compliant and represents the current production recommendation from TT Electronics/Optek Technology.

Both substitute parts are available in bulk packaging and provide improved regulatory compliance compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can OPB902W55Z and OPB912W55Z be used interchangeably with OPB902W55?

A: Yes. Both parts maintain identical electrical specifications (15 mA supply current, 4.75V ~ 5.25V supply voltage, 70ns response time) and mechanical parameters (0.375" sensing distance, through-beam sensing method, totem pole inverted output, chassis mount configuration, module wire leads package). Functional compatibility is assured.

Q: What is the difference between OPB902W55Z and OPB912W55Z?

A: Both parts are electrically and mechanically equivalent. The primary difference is the base product number (OPB902 versus OPB912). Both are active production parts with ROHS3 compliance and identical performance specifications.

Q: Why is the original OPB902W55 obsolete?

A: The OPB902W55 is no longer in active production. TT Electronics/Optek Technology has transitioned to the OPB902W55Z and OPB912W55Z variants, which offer improved regulatory compliance (ROHS3) while maintaining full functional equivalence.

Q: Are there packaging differences between these parts?

A: The OPB902W55 was available in standard packaging. Both OPB902W55Z and OPB912W55Z are supplied in bulk packaging, which is the current standard for these product lines.

Q: Do these parts meet current regulatory requirements?

A: OPB902W55Z and OPB912W55Z are both ROHS3 compliant. The original OPB902W55 is RoHS non-compliant. For applications requiring regulatory compliance, either substitute part is appropriate.
