Substitute Part Grouping Explanation

Substitution for the OPB982T11 is determined by strict equivalence across the following critical parameters: sensing distance (0.125" / 3.18mm), sensing method (through-beam), output configuration (totem pole inverted), supply current (15 mA), supply voltage range (4.75V ~ 5.25V), response time (70ns), operating temperature range (-40°C ~ 70°C), mounting type (chassis mount), and package type (module with wire leads). All substitute parts listed maintain these electrical and mechanical specifications without deviation. The primary distinction among substitutes is product status and compliance certification, with active parts offering continued availability and RoHS3 compliance compared to the obsolete OPB982T11.

Engineering Selection Recommendations

All listed substitute parts maintain complete electrical and mechanical equivalence to the OPB982T11 across all specified parameters. The primary advantage of selecting any active substitute is product availability and RoHS3 compliance certification. The OPB982T11's obsolete status necessitates transition to an active equivalent for new production and long-term system support.

For applications requiring immediate availability, OPB992P51Z offers the highest inventory level (69,800 pcs) while maintaining full parameter equivalence. OPB982P51Z and OPB982T51Z provide direct base product family continuity with 1,937 and 1,842 pcs in stock respectively. OPB932W51Z and OPB932W55Z represent alternative base product families within the same Photologic® series, each with confirmed inventory and active product status.

All substitute parts carry identical REACH unaffected status and EAR99 ECCN classification as the original part. Selection among substitutes should be based on supply chain availability, packaging preference (bulk), and internal design documentation requirements rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can OPB982T11 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical electrical specifications (15 mA supply current, 4.75V ~ 5.25V supply voltage, 70ns response time), mechanical specifications (0.125" sensing distance, through-beam sensing method, totem pole inverted output, chassis mount, module with wire leads), and operating temperature range (-40°C ~ 70°C). Direct substitution is electrically and mechanically valid.

Q: What is the primary reason to transition from OPB982T11?

A: The OPB982T11 is classified as obsolete. All listed substitutes are active products with confirmed current availability and RoHS3 compliance certification, ensuring long-term supply chain continuity and regulatory compliance for new designs and production runs.

Q: Are there differences in output behavior between the OPB982T11 and substitute parts?

A: No. All parts share identical output configuration (totem pole, inverted) and response time (70ns). Output behavior is equivalent across all listed parts.

Q: Does packaging differ among the substitutes?

A: The OPB982T11 is listed with unspecified packaging. All substitute parts are supplied in bulk packaging. Confirm bulk packaging compatibility with your procurement and assembly processes before selection.

Q: Which substitute offers the best supply availability?

A: OPB992P51Z maintains the highest inventory level at 69,800 pcs. OPB992N55Z follows with 20,299 pcs. Both are suitable for high-volume production requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliant certification. The original OPB982T11 is RoHS non-compliant, making compliance upgrade an additional benefit of substitution.
