• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-Beam
• Output configuration: Phototransistor
• Maximum collector current: 30 mA
• Maximum forward current: 50 mA
• Collector-emitter breakdown voltage: 30 V
• Operating temperature range: -40°C ~ 85°C
• Package configuration: Module, Pre-Wired
• Sensor type: Unamplified

Parts meeting all these specifications within the OPB880 base product family are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The OPB880N11Z is a direct parametric equivalent to the OPB880N55Z. Both parts maintain identical electrical specifications, mechanical configuration, and regulatory compliance status. Selection between these parts is based on availability and inventory considerations rather than functional differences.

Both parts are Active products with RoHS3 compliance and REACH Unaffected status, ensuring suitability for current design requirements and regulatory environments. The identical MSL rating (1 - Unlimited) indicates equivalent moisture handling characteristics for storage and assembly processes.
