Substitute Part Grouping Explanation

Substitute parts for the OPB481T11Z are identified based on strict equivalence across the following critical parameters:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-Beam
• Output configuration: NPN - Open Collector, Buffer
• Supply voltage range: 4.5V ~ 16V
• Supply current: 7.5 mA
• Response time: 50ns
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Chassis Mount
• Package type: Module, Wire Leads

Parts meeting all these criteria are classified as direct substitutes within the OPB481 base product family.

Parameter Comparison

Engineering Selection Recommendations

Both OPB481T11Z and OPB481L11Z are active products with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and lead time considerations. Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can OPB481L11Z be used as a direct replacement for OPB481T11Z?

A: Yes. Both parts share identical electrical parameters, sensing characteristics, output configuration, and physical packaging. They are interchangeable within the same circuit design.

Q: What determines compatibility between these optical sensors?

A: Compatibility is determined by matching sensing distance (0.125"), sensing method (through-beam), output type (NPN open collector), supply voltage range (4.5V ~ 16V), response time (50ns), operating temperature range (-40°C ~ 85°C), and package type (module with wire leads).

Q: Are there any compliance differences between the substitute parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited).

Q: What is the significance of the base product number OPB481?

A: The base product number OPB481 identifies the core optical sensor design family. Variants within this family (such as T11Z and L11Z) may differ in specific manufacturing or sourcing details but maintain the same functional specifications.
