Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the OPB980P11. Selection among active alternatives should be based on the following factors:

Product Status: The OPB980P11 is obsolete. All substitute parts listed are active products with ongoing manufacturer support and availability.

Regulatory Compliance: The original OPB980P11 is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement.

Packaging Consideration: OPB980P11Z is available in bulk packaging, matching the original part designation structure with the "Z" suffix indicating RoHS3 compliance.

Inventory Availability: OPB980L55Z offers the highest inventory level at 20,399 units, followed by OPB980P51Z at 2,412 units and OPB930W51Z at 2,332 units, providing supply chain flexibility for volume requirements.

Base Product Families: Substitute parts are distributed across OPB980, OPB930, and OPB940 base product numbers within the Photologic® series, all maintaining identical functional specifications.

Frequently Asked Questions (FAQ)

Q: Can OPB980P11 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts maintain identical electrical specifications (15 mA supply current, 4.75V ~ 5.25V supply voltage, 70ns response time), identical sensing characteristics (0.125" through-beam distance), identical output configuration (Totem Pole, Buffer), and identical mechanical packaging (Module, Wire Leads). Direct circuit substitution is supported without design modification.

Q: What is the difference between OPB980P11 and OPB980P11Z?

A: OPB980P11Z is the active, RoHS3-compliant equivalent of the obsolete OPB980P11. The "Z" suffix indicates RoHS3 compliance. All electrical and mechanical parameters are identical. OPB980P11Z is the primary recommended substitute for direct replacement.

Q: Why are there multiple substitute part numbers (OPB980, OPB930, OPB940 series)?

A: These represent different base product families within the Photologic® series. Despite different base numbers, all listed parts meet identical specifications for sensing distance, sensing method, output configuration, supply parameters, response time, operating temperature, and packaging. The variation in base product numbers reflects different design generations or internal product line organization by the manufacturer, but functional equivalence is maintained.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original OPB980P11 is RoHS non-compliant. For new designs or procurement requiring regulatory compliance, any of the listed active substitutes satisfy current environmental requirements.

Q: Does packaging type affect substitution?

A: All parts use identical packaging: Module, Wire Leads with Chassis Mount configuration. Packaging differences are limited to commercial packaging (bulk vs. other formats), which do not affect electrical or mechanical compatibility. The functional package type remains constant across all substitutes.

Q: What is the supply voltage tolerance for these optical sensors?

A: The supply voltage range is 4.75V ~ 5.25V for all parts. This represents a standard 5V nominal supply with ±5% tolerance, suitable for standard logic-level power supplies and embedded system applications.
