AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 192 pulses per revolution (PPR) and 4-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 chassis mount configuration suitable for motor applications.

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
• Moisture Sensitivity Level: 1 (Unlimited)

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain all critical electrical and mechanical parameters. The primary distinction is that substitute parts feature programmable pulses per revolution, allowing configuration to 192 PPR or other values as required. Both substitutes are active products with current manufacturing status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable replacements for the obsolete AMT303-V based on electrical and mechanical compatibility. The primary selection criterion between the two substitutes is termination style:

• AMT313Q-V: Terminal Pins termination, packaged in Box
• AMT313S-V: Connector termination, packaged in Box

Selection should be based on the existing system's connector interface requirements. Both substitutes carry active product status with ROHS3 compliance, providing superior regulatory alignment compared to the original RoHS Compliant designation. The programmable PPR feature of both substitutes allows configuration to match the original 192 PPR specification or other 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 equivalent in terms of electrical operation and mechanical mounting. The difference lies in termination style: AMT313Q-V uses terminal pins while AMT313S-V uses a connector. Selection depends on your system's existing interface.

Q: What is the advantage of programmable PPR in the substitute parts?

A: The AMT313Q-V and AMT313S-V allow PPR configuration, enabling the encoder to be set to 192 PPR to match the original AMT303-V specification or adjusted to other values if system requirements change.

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

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V specification.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate RoHS compliance. ROHS3 represents the current regulatory standard. Both the original and substitute parts meet hazardous substance restrictions.

Q: Do the substitute parts have the same mounting configuration?

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

Q: Which substitute should I choose if I need to minimize design changes?

A: If your current system uses terminal pins, select AMT313Q-V. If your system uses connectors, select AMT313S-V. Both maintain identical electrical and mechanical parameters otherwise.
