AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 250 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 suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by the following critical parameters that must remain consistent across alternative components:

• Encoder Type: Incremental operation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation-based output
• Termination Style: Pin-based connection

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain compatibility across these core parameters. The primary distinction between these alternatives is the pulses per revolution specification: while the AMT303-V provides fixed 250 PPR output, the substitute parts feature programmable PPR capability, allowing configuration to match the original 250 PPR specification or other required values within the encoder's programmable range.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes should be based on termination requirements:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, providing direct mechanical and electrical compatibility for existing connector interfaces.

AMT313S-V features connector-based termination, requiring interface modification but offering standardized connector-based integration for new designs.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance of the original part, and maintain REACH unaffected status. The programmable PPR capability of both alternatives provides operational flexibility, allowing configuration to the original 250 PPR specification or adjustment to alternative values as system requirements dictate.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain the core electrical and mechanical parameters required for substitution: incremental encoder type, 5V supply, commutation output, right-angle orientation, and chassis mount capability. The primary difference is termination style. AMT313Q-V uses terminal pins matching the original; AMT313S-V uses a connector interface requiring mechanical redesign.

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

A: The AMT303-V provides fixed 250 PPR output. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to 250 PPR to match the original specification or to alternative values within the encoder's programmable range. This flexibility supports both direct replacement and system optimization scenarios.

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

A: The substitute parts carry ROHS3 compliance, which represents a more current regulatory standard than the RoHS compliance of the AMT303-V. Both maintain REACH unaffected status. These differences represent regulatory advancement rather than functional degradation.

Q: Which substitute should be selected for new designs?

A: Selection depends on connector interface requirements. For systems requiring terminal pin connections, AMT313Q-V is appropriate. For systems utilizing connector-based interfaces, AMT313S-V is suitable. Both parts are active products with current manufacturing support.

Q: What is the inventory status of these alternatives?

A: AMT313Q-V has 1349 units in stock; AMT313S-V has 1045 units in stock. Both are available as new original components.
