AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 200 pulses per revolution (PPR) output. This component is designed for chassis mount and motor applications requiring precise rotational feedback with commutation output in a right-angle orientation. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

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 support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Environmental Compliance: RoHS and REACH status must be maintained

The substitute parts AMT313Q-V and AMT313S-V meet these core requirements. Both are active products from CUI Devices in the AMT31 series with programmable pulses per revolution capability, allowing configuration to match the original 200 PPR specification when required.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable replacements for the obsolete AMT303-V based on functional parameter alignment and active product status. The primary distinction between the two substitutes is termination style:

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

Selection between these substitutes depends on the existing system's connector interface requirements. Both maintain full compliance with RoHS3 and REACH regulations, exceeding the original part's RoHS Compliant status. The programmable pulses per revolution feature of both substitutes provides flexibility for configuration to the original 200 PPR specification or alternative resolutions as system requirements evolve.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core functional and environmental requirements of the AMT303-V. The selection between them depends on termination style compatibility with your system. AMT313Q-V uses terminal pins; AMT313S-V uses a connector interface.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to match the original 200 PPR specification or other resolutions. This provides design flexibility while maintaining compatibility with the AMT303-V's core functionality.

Q: Are there packaging differences between the main part and substitutes?

A: The AMT303-V packaging is listed as "-" (unspecified). Both substitutes are packaged in Box format. Confirm packaging compatibility with your procurement and assembly processes.

Q: Do the substitute parts maintain the same environmental compliance?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 Compliant and REACH Unaffected, meeting or exceeding the original part's compliance status.

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

A: Terminal pins provide direct solder or crimp connections to the PCB or harness. Connector termination uses a mated connector interface. Selection depends on your system's existing interface design.
