Substitute Part Grouping Explanation

Substitution eligibility for the OPB483L11Z is determined by strict equivalence across the following critical parameters:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-beam
• Output configuration: NPN open collector, inverted
• Supply voltage range: 4.5V ~ 16V
• Supply current: 7.5 mA
• Response time: 50ns
• Operating temperature range: -40°C ~ 85°C
• Series: Photologic®
• Manufacturer: TT Electronics/Optek Technology
• RoHS compliance: ROHS3 Compliant

The OPB493T11Z qualifies as a substitute based on identical electrical specifications and performance characteristics. Both parts share the same sensing distance, through-beam methodology, output configuration, power requirements, response time, and operating temperature range. The primary distinction between these parts is the mounting configuration: the OPB483L11Z features wire leads for chassis mount applications, while the OPB493T11Z is configured for PCB mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the OPB483L11Z and OPB493T11Z are active production parts from TT Electronics/Optek Technology with ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application mounting requirements rather than electrical performance, as all functional parameters are identical. The OPB483L11Z is specified for wire lead chassis mount applications, while the OPB493T11Z is configured for PCB mount installations. Current inventory levels support both options: 1121 units of OPB483L11Z and 1038 units of OPB493T11Z are available.

Frequently Asked Questions (FAQ)

Q: Can OPB493T11Z replace OPB483L11Z in all applications?
