Engineering Selection Recommendations

The OPB360T11 is obsolete and no longer in production. All listed substitute parts maintain identical electrical and mechanical specifications while offering active product status, ensuring continued availability and manufacturing support.

Selection among the substitute parts should be based on:

Product Status: All substitutes are in active production, providing long-term supply chain stability compared to the obsolete OPB360T11.
Compliance Certifications: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original component.
Inventory Availability: Current stock levels vary across substitute part numbers. OPB360T51 offers the highest inventory (2007 Pcs), followed by OPB365T55 (4496 Pcs), providing procurement flexibility.
Packaging Considerations: All substitutes are available in bulk packaging, suitable for production environments requiring component procurement in standard quantities.

Frequently Asked Questions (FAQ)

Q: Can OPB360L11, OPB360L51, and OPB360L55 be used as direct replacements for OPB360T11?

A: Yes. These parts share identical electrical specifications (50 mA forward current, 30 mA collector current, 30 V breakdown voltage), sensing distance (0.125"), sensing method (through-beam), output configuration (phototransistor), operating temperature range (-40°C to 85°C), and mounting type (through hole PCB mount). The primary difference is product status: OPB360T11 is obsolete while these alternatives are active.

Q: What is the difference between OPB360 and OPB365 and OPB370 series parts?

A: Within the provided data, OPB360, OPB365, and OPB370 series parts maintain identical electrical and mechanical parameters. The series designation reflects internal manufacturer classification but does not affect functional equivalence for the specified application parameters.

Q: Are there packaging differences among the substitute parts?

A: All substitute parts listed are supplied in bulk packaging. The OPB360T11 original part does not specify packaging type in the provided data, while all active substitutes are available in bulk format suitable for standard production procurement.
