Substitute Part Grouping Explanation

Substitute parts for the OPB880L55Z are selected based on strict electrical and mechanical parameter matching. The critical parameters that determine substitution eligibility are:

Sensing Distance: 0.125" (3.18mm)
Sensing Method: Through-Beam
Output Configuration: Phototransistor
Current - DC Forward (If) (Max): 50 mA
Current - Collector (Ic) (Max): 30 mA
Voltage - Collector Emitter Breakdown (Max): 30 V
Operating Temperature: -40°C ~ 85°C
Mounting Type: Chassis Mount
Package / Case: Module, Pre-Wired
Type: Unamplified
RoHS Status: ROHS3 Compliant
