AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in a 4-pole right angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this encoder model.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V must satisfy the following critical parameters to ensure functional compatibility:

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm–8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Output Type: Commutation (required match)

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain these core electrical and mechanical parameters. Both substitute parts feature programmable pulses per revolution, which accommodates the fixed 800 PPR specification of the AMT303-V while providing additional flexibility for future applications.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product offerings from CUI Devices and represent direct functional substitutes for the obsolete AMT303-V. Selection between these two alternatives depends on termination requirements:

AMT313Q-V: Features terminal pin termination, matching the original AMT303-V termination style. This option minimizes integration changes in existing designs.

AMT313S-V: Features connector termination, providing an alternative interface option. This configuration may require connector adaptation depending on system design.

Both substitute parts maintain full compliance with RoHS3 and REACH regulations, exceeding the RoHS compliance level of the original part. The programmable pulses per revolution specification of both substitutes accommodates the fixed 800 PPR requirement of the AMT303-V while supporting broader application flexibility.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical compatibility requirements. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on your system's termination requirements.

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 800 PPR to match the AMT303-V specification. This programmability also enables these parts to serve multiple applications beyond the fixed 800 PPR requirement of the original encoder.

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

A: The AMT303-V is supplied in standard packaging, while AMT313Q-V and AMT313S-V are supplied in box packaging. This difference does not affect functional performance or integration.

Q: Do the substitute parts meet current regulatory standards?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original AMT303-V meets RoHS compliance but is classified as obsolete.

Q: Which substitute part should I select for a direct replacement?

A: AMT313Q-V is the recommended direct replacement due to matching terminal pin termination. If your application requires connector termination, AMT313S-V is the appropriate alternative.
