Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the OPB982L55. The primary distinction between the original part and substitutes is product status and regulatory compliance.

The OPB982L55 is classified as obsolete and carries RoHS non-compliant status. All substitute parts listed are active products with ROHS3 compliance, making them suitable for new designs and systems requiring current regulatory adherence.

For applications requiring immediate availability, OPB992P51Z offers the highest inventory level at 69,800 units. OPB992N55Z provides 20,299 units. Both maintain identical electrical specifications and operating parameters as the original OPB982L55.

Frequently Asked Questions (FAQ)

Q: Can OPB982L55 substitutes be used as direct replacements in existing designs?

A: Yes. All substitute parts maintain identical sensing distance (0.125"), sensing method (through-beam), output configuration (totem pole inverted), supply voltage (4.75V ~ 5.25V), supply current (15 mA), response time (70ns), operating temperature range (-40°C ~ 70°C), and package type (module with wire leads). Electrical and mechanical compatibility is complete.

Q: What is the difference between the various substitute part numbers?

A: Substitute parts differ only in base product designation (OPB932, OPB942, OPB982, OPB992 series) and packaging variant codes. All maintain identical electrical performance and mechanical specifications required for substitution.

Q: Why is RoHS compliance important for selecting a substitute?

A: The original OPB982L55 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements for manufacturing and distribution in regulated markets.

Q: Which substitute part has the best availability?

A: OPB992P51Z has the highest inventory at 69,800 units, followed by OPB992N55Z at 20,299 units. Both are active products with full ROHS3 compliance.

Q: Are there any performance differences between substitute options?

A: No. All substitute parts share identical electrical parameters: 15 mA supply current, 4.75V ~ 5.25V supply voltage, 70ns response time, and -40°C ~ 70°C operating temperature range. Selection can be based on availability, packaging preference, and supply chain considerations.
