Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V is identified as a substitute for the AMT303LD-V based on the following matching parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center actuators
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configurations
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated at MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 192 PPR. The AMT313Q-V also carries an active product status, making it a viable long-term alternative.

Parameter Comparison
