AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 250 pulses per revolution (PPR) output. This encoder features an 8-pole right angle orientation with commutation output, designed for chassis mount and motor applications. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must remain consistent:

• Encoder Type: Incremental
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: Required

The AMT303-V specifies a fixed 250 PPR output. Substitute parts AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration to 250 PPR to match the original specification. Both substitutes maintain identical supply voltage, actuator geometry, mounting configuration, and environmental compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination requirements:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, providing direct mechanical and electrical compatibility with existing connector interfaces. This part carries ROHS3 compliance certification.

AMT313S-V provides connector-based termination, requiring interface adapter consideration if the original system uses terminal pin connections. This part also carries ROHS3 compliance certification.

Both substitutes support programmable PPR configuration, enabling the 250 PPR setting required to match the original AMT303-V specification. The programmable capability provides additional flexibility for future system modifications without component replacement.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the AMT303-V output specification?

A: Yes. Both substitute parts feature programmable PPR capability and can be configured to 250 PPR, matching the fixed output of the AMT303-V. All other electrical and mechanical parameters remain identical across the three encoders.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: The termination style differs. AMT313Q-V uses terminal pins, matching the original AMT303-V. AMT313S-V uses a connector interface. Selection depends on the existing system connector type.

Q: Are the substitute parts compatible with 5V supply systems?

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, identical to the AMT303-V.

Q: Do the substitute encoders maintain the same mounting configuration?

A: Yes. All three encoders feature chassis mount orientation for motor applications with right angle configuration and 2mm ~ 8mm open center actuator type.

Q: What is the significance of ROHS3 compliance on the substitute parts?

A: ROHS3 compliance on AMT313Q-V and AMT313S-V represents current regulatory certification. The original AMT303-V carries RoHS Compliant status. Both certifications satisfy RoHS requirements for electronic component manufacturing and distribution.
