AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1000 pulses per revolution with commutation output in a right-angle orientation. This encoder is designed for chassis mount and motor applications with a 2mm to 8mm open center actuator and 5V supply voltage. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

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 operation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• Termination Compatibility: Terminal Pins or Connector

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain these core electrical and mechanical specifications. The primary difference is that substitute parts feature programmable pulses per revolution, allowing configuration to match the original 1000 PPR specification or other required values within the encoder's programmable range.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for applications currently using the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH requirements, meeting modern regulatory standards.

The primary distinction between the two substitutes is termination style: AMT313Q-V retains terminal pin termination matching the original AMT303-V configuration, while AMT313S-V uses connector termination. Selection between these substitutes depends on the existing system's connector interface requirements.

The programmable pulses per revolution feature in both substitutes provides design flexibility, allowing configuration to the original 1000 PPR specification or adjustment to alternative values as system requirements evolve.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used interchangeably with AMT303-V?

A: Both are functionally compatible substitutes provided the pulses per revolution are programmed to 1000 to match the original specification. The primary consideration is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination.

Q: What is the difference between terminal pin and connector termination?

A: Terminal pin termination uses individual pins for direct soldering or insertion into pin headers. Connector termination uses a mated connector interface. Selection depends on the existing system's interface design.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant, exceeding the RoHS compliance level of the original AMT303-V.

Q: Can the programmable pulses per revolution be set to values other than 1000?

A: The substitute parts feature programmable pulses per revolution capability. Configuration to 1000 PPR ensures functional equivalence to the original AMT303-V. Alternative PPR values may be available depending on encoder firmware specifications.

Q: What is the supply voltage requirement for all three encoders?

A: All three encoders require 5V supply voltage. No voltage conversion or additional power conditioning is required when substituting.

Q: Are there inventory considerations for these parts?

A: The AMT303-V is obsolete with limited remaining stock. Both AMT313Q-V and AMT313S-V are active products with current manufacturing and established inventory levels, ensuring reliable procurement for new designs and replacements.
