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 suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental
• Output Type: Commutation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built-in Switch: No

The substitute parts AMT313Q-V and AMT313S-V maintain these core electrical and mechanical characteristics. The primary distinction between the main part and substitutes is the pulses per revolution specification: the AMT303-V provides fixed 200 PPR output, while the substitute models feature programmable PPR capability. This programmability allows the substitutes to be configured to match the 200 PPR requirement of the original component.

Parameter Comparison

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 identical to the original AMT303-V, providing direct mechanical and electrical compatibility for existing connector designs.

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 component. Both maintain REACH Unaffected status and identical moisture sensitivity classification. The programmable PPR capability of both substitutes allows configuration to the 200 PPR specification of the original part.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain identical electrical and mechanical parameters including encoder type, output type, supply voltage, actuator type, mounting type, and orientation. The programmable PPR feature allows configuration to match the 200 PPR output of the original component. The primary difference is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

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

A: The primary distinction is termination style. AMT313Q-V provides terminal pin termination, maintaining compatibility with existing AMT303-V connector designs. AMT313S-V uses connector-based termination, requiring interface redesign but offering standardized connector integration.

Q: Are the substitute parts compliant with current regulations?

A: Both AMT313Q-V and AMT313S-V carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: How is PPR configuration handled on the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR capability. Configuration to 200 PPR must be performed according to CUI Devices programming specifications for these models.

Q: Are inventory levels sufficient for both substitutes?

A: Current inventory shows 1349 units of AMT313Q-V and 1045 units of AMT313S-V available as new original stock.
