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 8-pole commutation output. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The AMT303-V is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional equivalence:

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

The AMT313Q-V and AMT313S-V both satisfy these core electrical and mechanical compatibility criteria. The primary distinction between substitutes is the pulses per revolution specification and termination style, which are addressed in the parameter comparison table below.

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 consistent with the original AMT303-V design. This option minimizes integration changes in existing connector designs.

• AMT313S-V: Provides connector-based termination, which may require interface redesign but offers standardized connector compatibility for new implementations.

Both substitutes feature programmable pulses per revolution, enabling configuration to match the original 192 PPR specification or alternative resolution requirements. Both meet ROHS3 compliance and maintain identical electrical supply, mounting, and mechanical specifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V?

A: Both parts satisfy the core electrical and mechanical compatibility requirements. The primary consideration is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while 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 the original 192 PPR specification or alternative resolutions as required by system design.

Q: Are there compliance differences between the original and substitute parts?

A: The original AMT303-V is RoHS Compliant. Both substitutes meet the more recent ROHS3 Compliant standard, which is a higher compliance level. All three parts maintain identical moisture sensitivity ratings and REACH unaffected status.

Q: Which substitute should be selected for new designs?

A: Selection depends on termination interface requirements. For designs requiring terminal pin connections, AMT313Q-V is appropriate. For designs utilizing connector-based interfaces, AMT313S-V is suitable.

Q: Are there inventory considerations for these substitutes?

A: AMT313Q-V has 1349 units in stock, and AMT313S-V has 1045 units in stock, both in new original condition.
