Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the OPB980P11Z. Selection among equivalent parts should be based on inventory availability and application-specific packaging variant requirements. The OPB980L55Z offers the highest inventory level (20,399 pcs), providing supply chain stability for high-volume applications. Parts within the OPB980 base product family (OPB980L51Z, OPB980L55Z, OPB980P51Z, OPB980T11Z, OPB980T51Z, OPB980T55Z) maintain identical specifications to the OPB980P11Z and represent direct substitutes. Cross-family substitution to OPB930W51Z, OPB940W51Z, OPB940W55Z, and OPB990L11Z is valid when electrical and mechanical parameters remain the controlling factors in system design.

Frequently Asked Questions (FAQ)

Q: What determines if an OPB980P11Z substitute is functionally equivalent?

A: Functional equivalence is determined by matching all electrical parameters (voltage supply 4.75V ~ 5.25V, current 15 mA, response time 70ns), sensing specifications (0.125" distance, through-beam method, totem pole buffer output), operating temperature range (-40°C ~ 70°C), and mechanical form factor (module with wire leads, chassis mount). All listed substitutes meet these criteria.

Q: Can I use OPB980P11Z substitutes interchangeably in existing designs?

A: Yes. All substitute parts listed maintain identical electrical specifications, output configuration, sensing distance, and package type. Direct substitution is valid without circuit or mechanical redesign when the part number variant differs only in packaging or base product designation within the Photologic® series.

Q: What is the difference between OPB980P11Z and OPB980L55Z?

A: Both parts share identical electrical and mechanical specifications. The difference lies in packaging variant designation (P versus L suffix) and inventory availability. OPB980L55Z has significantly higher stock (20,399 pcs versus 1,055 pcs for OPB980P11Z).

Q: Are cross-family substitutions (OPB930, OPB940, OPB990) safe?

A: Cross-family substitution is valid when all specified parameters remain constant. OPB930W51Z, OPB940W51Z, OPB940W55Z, and OPB990L11Z are qualified substitutes because they maintain identical sensing distance, sensing method, output configuration, voltage/current specifications, response time, operating temperature, package type, and mounting configuration.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant and maintain Active product status. REACH status is Unaffected for all parts, and ECCN classification is EAR99 across the entire substitute list.
