AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 1000 pulses per revolution with 8-pole commutation output in a right-angle orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The encoder operates at 5V supply voltage with a 2mm to 8mm open center actuator and chassis mount configuration suitable for motor integration applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by alignment across the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Detent and Built-in Switch: Must match (No for both)

The substitute parts AMT313Q-V and AMT313S-V satisfy these core compatibility criteria. Both are active-status incremental encoders from CUI Devices with programmable pulses per revolution capability, allowing configuration to match the 1000 PPR specification of the original AMT303-V. The primary distinction between substitutes lies in termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status components with current manufacturing support, providing supply chain continuity for applications currently using the obsolete AMT303-V.

AMT313Q-V is the preferred direct substitute when terminal pin termination is required to match existing PCB layouts or connector designs. This part maintains identical termination methodology to the original AMT303-V while offering programmable PPR configuration.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. The connector interface may simplify integration in modular system designs but requires interface compatibility verification with the target application.

Both substitutes comply with ROHS3 standards, exceeding the RoHS compliance level of the original part. Both maintain the same moisture sensitivity classification and REACH unaffected status as the AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to operate at 1000 PPR like the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 1000 PPR to match the original specification.

Q: What is the primary difference between the two substitute parts?

A: The termination style differs. AMT313Q-V uses terminal pins, matching the AMT303-V configuration. AMT313S-V uses a connector interface. Selection depends on the target application's termination requirements.

Q: Are the substitute parts compatible with the same mounting locations as the AMT303-V?

A: Yes. Both substitutes share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center), ensuring mechanical compatibility.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original AMT303-V was RoHS compliant but not ROHS3 certified.

Q: What is the supply voltage requirement for the substitute parts?

A: Both substitutes operate at 5V supply voltage, identical to the AMT303-V.

Q: Are there inventory considerations when selecting between the two substitutes?

A: Both parts are in active production with current stock availability. AMT313Q-V has 1349 units in stock; AMT313S-V has 1045 units in stock.
