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 encoder features an 8-pole right-angle configuration with commutation output, designed for chassis mount and motor applications. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. Substitute encoders must maintain compatibility across electrical specifications, mechanical mounting, and output characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute encoders for the AMT303-V are identified based on strict alignment with the following critical parameters:

• Encoder Type: Must be incremental
• Supply Voltage: Must be 5V
• Mounting Type: Must support chassis mount and motor applications
• Orientation: Must be right angle configuration
• Actuator Type: Must accommodate 2mm ~ 8mm open center shaft
• Output Type: Must provide commutation output
• Termination Style: Compatible with terminal pins or connector-based termination

The AMT313Q-V and AMT313S-V meet these core electrical and mechanical requirements. Both are active-status products from CUI Devices' AMT31 series, offering programmable pulses per revolution capability while maintaining the same supply voltage, mounting configuration, and physical orientation as the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for applications requiring direct terminal pin termination. This encoder maintains identical termination methodology to the AMT303-V while offering programmable PPR configuration and active product status. ROHS3 compliance provides enhanced regulatory alignment compared to the original RoHS Compliant designation.

AMT313S-V serves as an alternative for systems where connector-based termination is acceptable or preferred. This variant provides the same electrical and mechanical compatibility as the AMT313Q-V but utilizes a connector termination interface instead of terminal pins. Selection between AMT313Q-V and AMT313S-V depends solely on termination style requirements within the target application.

Both substitutes are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both encoders meet the core electrical and mechanical specifications of the AMT303-V. 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 application's termination requirements.

Q: What is the key difference between AMT313Q-V and AMT313S-V?

A: The encoders are functionally identical except for termination style. AMT313Q-V provides terminal pin termination; AMT313S-V provides connector termination. Both maintain the same electrical output, supply voltage, mounting configuration, and physical orientation.

Q: Does the programmable PPR feature of the substitutes affect compatibility?

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, whereas the AMT303-V is fixed at 200 PPR. Both substitutes can be configured to 200 PPR to match the original specification, ensuring functional compatibility in existing designs.

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

A: The substitute parts carry ROHS3 Compliant status compared to the original RoHS Compliant designation. Both maintain REACH Unaffected status and identical moisture sensitivity levels. ROHS3 represents an updated compliance standard with no functional impact on encoder operation.

Q: What inventory status should I consider when selecting a substitute?

A: Both AMT313Q-V (1349 pcs) and AMT313S-V (1045 pcs) are in active production with substantial current inventory. The original AMT303-V (1117 pcs) is classified as obsolete, making the active-status substitutes the recommended choice for new designs and long-term system support.
