Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LESR 6-NP are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Current Sensing Capability: 6A nominal rating
• Sensor Technology: Hall Effect, Closed Loop topology
• Output Configuration: Ratiometric voltage output
• Sensitivity: 104.2 mV/A
• Frequency Response: 300 kHz bandwidth
• Accuracy and Linearity: ±1.25% accuracy and ±0.1% linearity
• Supply Voltage: 4.75V ~ 5.25V operating range
• Response Time: 400 ns
• Polarization: Bidirectional measurement capability
• Mounting and Package: Through Hole module configuration
• Environmental Compliance: RoHS Compliant, REACH Unaffected status
• Operating Temperature: -40°C ~ 105°C range

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Series designation changes (LESR to LXSR) do not affect functional equivalence when all electrical and mechanical parameters remain identical.
